Understanding Heart Disease

• Heart disease occurs when plaque develops in the arteries. This blocks important nutrients and oxygen from reaching this vital organ.
• Heart disease, sometimes called coronary heart disease (CHD), is the leading cause - Source of death among adults in the United States.
• Heart disease is caused by the build-up of plaque, a waxy substance made up of cholesterol, fatty molecules, and minerals.
• It accumulates over time when the inner lining of arteries is damaged by high blood pressure, cigarette smoking, or elevated cholesterol or triglycerides.
• Learning about the causes and risk factors of this disease may help you avoid heart problems.

Having family members who have or have had heart disease raises the chance of getting the condition.

Genes alone can increase the chances of developing heart disease, especially when combined with lifestyle risk factors. Having a parent with heart disease may slightly raise the chance of the condition slightly more - Higher risk of a sibling with heart disease, and even more so if they’re a twin.

 

How do demographics affect the risk of heart disease?

Biological factors can raise chances as well. For instance, the chance of heart disease increases around the age of 55 in females and 45 in males. 24%Trusted Source of people of South Asian descent develop heart disease, compared to only 8% of people who are white. People who are white have a heart disease rate of only 3.2%, compared to just over 5% in Hispanics and Black people.

 

Health conditions increasing the risk of heart disease.

High blood pressure, low-density lipoprotein (LDL) cholesterol (“bad” cholesterol), and triglycerides.

Diabetes –

 People with type 2 diabetes — and especially those who have reached middle age — are twice as likely. Adults with diabetes also tend to have heart attacks at a younger age. They’re more likely to experience multiple heart attacks if they have insulin resistance or high blood glucose levels. The reason for this is the relationship between glucose and blood vessel health. High blood glucose levels that aren’t managed can increase the amount of plaque that forms within the walls of the blood vessels. This hinders or stops the flow of blood to the heart. If you have diabetes, you can reduce the risk of heart disease by managing your blood sugar carefully. Follow a diet rich in fibre and low in sugar, fat, and simple carbohydrates. Managing blood sugar levels can also help lower the risk of eye disease and circulation problems. Also, maintain a healthy weight. And if you smoke, now’s a good time to consider quitting.

Depression

Depression develops heart disease at higher rates than the general population. Depression can lead to some changes in the body that can increase the chance of developing heart disease or having a heart attack. Too much stress, consistently feeling sad, can elevate your blood pressure. Depression also raises your levels of a substance called C-reactive protein (CRP). CRP is a marker for inflammation in the body. Higher than typical levels of CRP have also been shown to predict heart disease.

Depression can also lead to a decreased interest in daily activities. This includes daily routines like exercise that are necessary to help prevent heart disease. Other unhealthy behaviours that can also raise the chance of heart disease may follow, such as skipping medications or not putting effort into eating a healthy diet.

Behaviour 

Unhealthy lifestyle choices play a big role. Some unhealthy lifestyle choices that can contribute to heart disease include:

• living a sedentary lifestyle and not getting enough physical exercise
• eating an unhealthy diet that’s high in fat proteins, trans fats, sugary foods, and sodium
• smoking
• alcohol misuse
• staying in a high-stress environment without proper stress management techniques
• not managing your diabetes

 

Signs the heart is quietly failing.

Heart failure occurs when the heart can’t pump enough blood to the body. Common symptoms include shortness of breath, fatigue, oedema, and feeling faint or weak. Other symptoms may include sudden weight gain, loss of appetite, confusion, coughing, and swelling in various parts of the body. Heart failure is a chronic condition, but it can also occur acutely.

A heart attack is a problem caused by blocked coronary arteries that feed the heart. Heart failure is a muscle problem. If you experience sudden, severe, and sharp chest pain, call local emergency services right away. It may be a sign of a heart attack.

Other symptoms of a heart attack may include:

•           shortness of breath

•           pain in your left arm, shoulder, or neck

•           nausea or sweating

•           light-headedness or dizziness

•           fatigue

A heart attack may lead to heart failure if it causes a significant amount of heart muscle damage.

Takeaway 

Heart disease is dangerous, but it can be prevented in many cases. Everyone would benefit from maintaining a heart-healthy lifestyle, but it’s particularly important for those with increased risk.

Prevent heart disease by doing the following:

• Exercise regularly.
• Maintain a healthy diet.
• Maintain a healthy weight.
• Reduce stress in your life.
• Stop smoking.
• Drink in moderation.
• Get annual physical exams from your doctor to detect abnormalities and assess risk factors.
• Take supplements, as advised by your doctor.
• Know the warning signs of heart disease, heart attack, and stroke.

You cannot control your genetics, and as a result, some people are more susceptible to heart disease than others. That said, living a healthy lifestyle is one of the most effective ways you can reduce the chance of getting heart disease.

 

Complications of Heart Disease:

• Heart failure
• Heart attack
• Stroke
• Pulmonary embolism
• Cardiac arrest
• PAD
• AFib
• Angina

Overview

Heart disease is an umbrella term, meaning it describes many conditions that affect a person’s heart health. Heart disease describes conditions that affect a person’s heart muscle, heart valves, coronary arteries, or heart rhythm. Each of these components plays an important part in a person’s overall heart health. When a person learns they have heart disease, they need to make lifestyle changes to slow the progression of the disease. Heart disease can cause many potentially fatal complications if left untreated - an estimated 1 in 4 deaths in the United States is due to heart disease.

Heart failure

Heart failure occurs when the heart cannot adequately pump blood throughout the body. The heart muscle is very strong. However, over time, the muscle can be affected and have trouble doing its job. The heart starts to compensate by beating faster, building up more muscle, or stretching to accommodate more blood. Over time, these methods of compensating can affect the heart’s function and result in heart failure. This can cause shortness of breath, dizziness, confusion, and the build-up of fluid in the body, causing swelling.

Heart attack

A heart attack occurs when the coronary arteries narrow so much that they cut off the blood supply to the heart. Often, this is the result of cholesterol buildup in the arteries called atherosclerosis. A piece of the cholesterol breaks off and can block the blood vessel. The heart cells begin to die as they’re deprived of oxygen. Symptoms include shortness of breath and severe chest pain that may radiate to the back, jaw, or left arm. However, women may experience different symptoms associated with a heart attack and heart disease, which are discussed below.

Stroke

When the heart isn’t working effectively, blood clots are more likely to form in the blood vessels. A stroke occurs when one of these clots lodges in a blood vessel in the brain and cuts off blood flow. This is called an ischemic stroke. Ischemic stroke symptoms include:

• numbness on one side of the body
• confusion
• trouble speaking
• loss of balance or coordination

If a person doesn’t seek treatment quickly enough, too many brain cells may die in important areas of the brain that control speech, strength, memory, and more. If a person does live through the stroke, these elements of brain function may never return or may take time and rehabilitation to recover.

Complications

Heart disease can greatly affect a person’s quality of life. If a person experiences angina, they may be afraid to exert themselves for fear of chest pain or other uncomfortable symptoms. Those with heart failure can develop swelling, dizziness, and other symptoms that can affect their ability to complete daily tasks. A person with diagnosed heart disease must also live with the stress of knowing they have a long-term illness that could result in a cardiac event, such as a heart attack or stroke.

The long-term outlook for people with heart disease depends upon many factors. These include the type of underlying heart disease, the person’s reaction to the medications, and the extent and severity of impairment. If a doctor diagnoses you or a loved one with heart disease, a medication and a healthy lifestyle regimen should be followed to prevent worsening complications.

Heart disease is considered a chronic condition, and there can be complications following periods of medication-induced improvement. However, heart disease remains the leading cause of death for both men and women. 

Imaging Tests to Diagnose Heart Disease

Stress echocardiography is an alternative to the nuclear stress test. Many people prefer this test because it does not use a radioactive agent. The movements of the ventricular walls are compared during stress and at rest. Wall motion drops during stress. Coronary angiography by cardiac catheterisation is the best way to evaluate coronary heart disease. Under the guidance of an X-ray camera, a long, thin plastic tube (catheter) is threaded into the opening of your coronary arteries from a blood vessel in either your groin (femoral artery) or your arm (radial artery). Once the catheter reaches the coronary artery opening, it injects a small amount of iodine dye, which makes the coronary arteries visible on the X-ray screen. Pictures of the coronary arteries are then recorded in a computer for later review. The images show the diameter of the coronary arteries and any blockages that narrow them.

Coronary angiography is an invasive test. In experienced hands, the risk of complications is less than 1%; however, it is the only test that helps a cardiologist to determine precisely whether to treat you with bypass surgery, a less-invasive technique such as angioplasty or stent placement, or medications.

Best Medications for Treating Heart Disease

Coronary artery disease decreases the blood supply to the heart from the blocked coronary artery. The lower blood flow may fail to meet the heart's demand for oxygen. Treatment aims to balance blood supply to the heart with heart oxygen demand and prevent worsening of coronary heart disease.

• Aspirin:
• Beta-blockers: 
• Nitro-glycerine: 
• Calcium channel blockers (CCBs): 
• ACE inhibitors: 

 

Statins: 

Clinical trials- include atorvastatin (Lipitor), pravastatin (Pravachol), simvastatin (Zocor), lovastatin (Manacor), and rosuvastatin (Crestor).

When angina symptoms worsen despite medications, one needs an invasive procedure in the cardiac catheterisation lab to clear the blocked artery. These procedures are performed by a cardiologist, not a cardiac surgeon, and have fewer complications.

Coronary angioplasty - 

Stents: A stent is a small, sieved, coil-like metallic tube or scaffold mounted over a balloon. The balloon is inflated at the blockage, which expands the stent. The balloon is then withdrawn, but the stent stays in place, keeping the artery from narrowing again. Like arteries treated with angioplasty alone, arteries treated with a stent can eventually close up again. The stent is a longer-lasting solution for many people.

Outlook for Heart Disease.

Recovery from coronary heart disease depends on many factors, including the following:

• the extent of coronary artery disease and the number of coronary arteries involved,
• the history of previous heart attacks or bypass surgery,
• the capacity for exercise or exertion,
• heart function (how well the heart contracts), and
• acuteness of symptoms. 

Open-Heart Surgery

Open-heart surgery involves cutting open and performing surgery on the muscles, valves, or arteries of the heart. You can help minimise some risks through caring for yourself and your incision after surgery. Open-heart surgery is sometimes called traditional heart surgery. Today, many new heart procedures can be performed with only small incisions, not wide openings. Therefore, the term “open-heart surgery” can be misleading.

Sudden Death

Recently news we have seen sudden death in youngsters, which can be a distressing event. That requires thorough investigation, including a review of the individual's medical history, family history, recent symptoms or complaints, and circumstances surrounding the death.

Causes of sudden death in a youngster include:

• Cardiac Issues: heart conditions such as hypertrophic cardiomyopathy (thickening of the heart muscle), arrhythmias (irregular heartbeats), or congenital heart defects could lead to sudden cardiac arrest.
• Trauma: Accidents result in sudden death due to severe trauma to vital organs.
• Drug Overdose: Illicit drugs or misuse of medications can cause sudden death, particularly if the drugs affect the cardiovascular or respiratory systems.
• Sudden Infant Death Syndrome. In infants under one year old, it is a leading cause of sudden and unexplained death. While its exact cause is unknown but abnormalities in the brain that control breathing and arousal from sleep.
• Infections: Severe infections, such as meningitis or sepsis, can lead to sudden death if not diagnosed and treated promptly.
• Neurological Causes: Conditions like epilepsy or brain aneurysms can lead to sudden death.
• Genetic Disorders: Certain genetic conditions can predispose to sudden death.
• Sudden Arrhythmia - sudden death in young individuals without any structural heart abnormalities.
• In many cases, sudden death in youngsters remains unexplained despite thorough examination, which can be incredibly challenging.

 

Heart Attack

Damage to the heart muscle caused by a loss of blood supply due to blockages in the arteries.

Urgent medical attention is usually recommended by healthcare providers. It can be dangerous or life-threatening if untreated. Very common (More than 1 crore cases per year in India)

What is a heart attack?  The heart muscle needs oxygen to survive. A heart attack occurs when the blood flow that brings oxygen to the heart muscle is severely reduced or cut off completely. This happens when the coronary arteries that supply the heart muscle with blood flow become narrowed from a build-up of fat, cholesterol and other substances that together are called plaque. This slow process is known as atherosclerosis. When plaque within a heart artery breaks, a blood clot forms around the plaque. This blood clot can block the blood flow through the artery to the heart muscle.

Ischemia is a condition in which the blood flow (and thus oxygen) is restricted or reduced in a part of the body. Cardiac ischemia is decreased blood flow and oxygen to the heart muscle. When damage or death to part of the heart muscle occurs due to ischemia, it’s called a heart attack, or myocardial infarction (MI).

About every 40 seconds, someone in the United States has a heart attack.

The process of atherosclerosis may have no symptoms in its early stages. But when an artery is narrowed by over 70%, muscle pain or cramps may occur when tissue needs more oxygen than it’s able to receive. When a coronary artery narrows and constricts blood flow, other nearby blood vessels that serve the heart sometimes expand to compensate, which may explain why there may be no warning signs. Such a network of expanded nearby blood vessels is called collateral circulation, and it helps protect some people from heart attacks by delivering needed blood to the heart. Collateral circulation can also develop after a heart attack to help the heart muscle recover.

When a heart attack occurs, the heart muscle that has lost blood supply begins to suffer injury. The amount of damage to the heart muscle depends on the size of the area supplied by the blocked artery and the time between injury and treatment.

The heart muscle damaged by a heart attack heals by forming scar tissue. It usually takes several weeks for your heart muscle to heal. The length of time depends on the extent of your injury and your rate of healing.

The heart is a tough organ. Even though part of it may have been severely injured, the rest of the heart keeps working. But, because of the damage, your heart may be weakened and unable to pump as much blood as usual.

With proper treatment and lifestyle changes after a heart attack, further damage can be limited or prevented.

How long will it take to recover from my heart attack? Heart attacks can have longer or shorter recoveries and complications. It depends on the size and location of the damage and the treatment of your heart attack. In the damaged area, scar tissue may form and doesn’t contract or pump as well as healthy muscle tissue. As a result, the extent of damage to the heart muscle can affect how well the heart pumps blood throughout the body.

The pumping function is lost, depending on the size and location of the scar tissue. Most heart attack survivors have some degree of coronary artery disease. and will have to make important lifestyle changes and possibly take medication to prevent a future heart attack. Taking these steps can help you lead a full, productive life.

Another common type of chest pain is called angina. It’s a recurring discomfort that usually lasts only a few minutes. Angina occurs when your heart muscle doesn’t get the blood supply and oxygen that it needs, and is a signal that you’re at higher risk of having a heart attack. The difference between angina and a heart attack is that angina attacks don’t permanently damage the heart muscle.

Different types of angina: - Stable angina, or angina pectoris. It often occurs during exercise or emotional stress when your heart rate and blood pressure increase, and your heart muscle needs more oxygen.  - Unstable angina. One of several acute coronary syndromes, it occurs while you’re resting or sleeping, or with little physical exertion. It comes as a surprise. Unstable angina can lead to a heart attack, and it should be treated as an emergency.  

Medical terms for a heart attack;

Acute coronary syndrome (ACS): The umbrella term is for situations in which the blood supplied to the heart muscle is suddenly blocked.  

STEMI: A common name for ST-elevation myocardial infarction, it's caused by a complete blockage in a coronary artery.

NSTEMI: A non-ST-elevation myocardial infarction is when an artery is partially blocked and severely reducing blood flow.

Myocardial infarction (MI): It occurs when an area of the heart muscle (myocardium) is damaged or dies after the blood supply is blocked. It’s the classic medical term for a heart attack.

Coronary thrombosis: It occurs when a clot is formed in one of the arteries that supply blood to the heart muscle. It's also called coronary occlusion.

Coronary occlusion: An obstruction of a coronary artery that hinders blood flow to some part of the heart muscle and can cause a heart attack.

Other causes of a heart attack besides blockage

Sometimes a coronary artery temporarily contracts or goes into spasm. When this happens, the artery narrows and blood flow to part of the heart muscle decreases or stops.

A spasm can occur in normal-appearing blood vessels as well as in vessels partly blocked by atherosclerosis. A severe spasm can cause a heart attack.

Another rare cause of a heart attack is spontaneous coronary artery dissection (SCAD), which is a spontaneous tearing of the coronary artery wall.

How is a heart attack different from cardiac arrest?

People often use these terms to mean the same thing, but they describe different events. A heart attack occurs when blood flow to the heart is blocked. It’s a circulation problem. With sudden cardiac arrest (SCA), the heart malfunctions and suddenly stops beating. Sudden cardiac arrest is an electrical problem caused by irregular heart rhythms called arrhythmias. A common and potentially deadly arrhythmia is ventricular fibrillation. This happens when the heart’s lower chambers suddenly start beating chaotically and don’t pump blood. A heart attack can cause ventricular fibrillation, which in turn can cause sudden cardiac arrest. Death can occur within minutes after the heart stops. Cardiac arrest may be reversed if CPR (cardiopulmonary resuscitation) is performed and a defibrillator is used within minutes to shock the heart and restore a normal heart rhythm.

Acute Coronary Syndrome

So, you’ve never heard of acute coronary syndrome? But what about a heart attack or unstable angina? These well-known conditions are both acute coronary syndromes (ACS), an umbrella term for situations in which blood supplied to the heart muscle is suddenly blocked. The blockage is usually due to a blood clot and can be sudden and complete. If a clot forms due to a plaque rupture, a part of the clot may break away and clog one of the coronary arteries, causing ACS. Though less common, spasms in the coronary artery may also limit blood flow. Regardless of the cause of the blockage, it’s damaging to the heart and a medical emergency.

What are the symptoms?

Chest pain or discomfort may immediately signal that something’s wrong with your heart. But other symptoms may leave you unsure of what’s wrong. Take note of these common signs of an acute coronary syndrome:

·        Chest pain or discomfort, which may involve pressure, tightness or fullness

·        Pain or discomfort in one or both arms, the jaw, neck, back or stomach

·        Shortness of breath

·        Feeling dizzy or lightheaded

·        Nausea

·        Sweating

Chest pain caused by acute coronary syndromes can come on suddenly, as is the case with a heart attack. Other times, the pain can be unpredictable or get worse even with rest – both hallmark symptoms of unstable angina. People who experience chronic chest pain resulting from decreased blood flow to the heart due to years of cholesterol build-up in their arteries can develop an acute coronary syndrome if a blood clot forms on top of the plaque build-up.

Diagnosis and Treatment

Careful medical history and give you a physical examination. If acute coronary syndrome is suspected, the following tests may be performed:  A blood test can show evidence that heart cells are dying. - An electrocardiogram (ECG or EKG) can diagnose an acute coronary syndrome by measuring the heart’s electrical activity.

If tests confirm blood flow to the heart has been blocked, - health care team will work quickly to restore it. Every second counts to prevent further damage to the heart muscle.

Treatment for acute coronary syndrome includes medicines and a procedure known as angioplasty, during which doctors inflate a small balloon to open the artery. A wire mesh tube called a stent may be permanently placed in the artery to keep it open. In hospitals not equipped to do angioplasty quickly, doctors may administer drugs to dissolve blood clots. 

Risk

Acute coronary syndromes, just like heart failure and stroke, are much more likely in people who have certain risk factors. These include:

·        Smoking

·        High blood pressure

·        High blood cholesterol

·        Diabetes

·        Physical inactivity

·        Being overweight or obese

·        A family history of chest pain, heart disease or stroke

Typical heart attack symptoms

·        Chest discomfort or pain. This discomfort or pain can feel like a tight ache, pressure, fullness or squeezing in the chest lasting more than a few minutes. This discomfort may come and go.

·        Upper body pain. Pain or discomfort may spread beyond the chest to the shoulders, arms, back, neck, teeth or jaw. Some people have upper-body pain with no chest discomfort.

·        Stomach pain. Pain may extend downward into the belly area and may feel like heartburn.

·        Shortness of breath. You may gasp for breath or try to take in deep breaths. This often occurs before any chest discomfort. Some people don't have chest discomfort.

·        Anxiety. You may feel a sense of doom or feel as if you're having a panic attack for no apparent reason.

·        Light-headedness. In addition to feeling chest pressure, you may feel dizzy or feel like you might pass out.

·        Sweating. You may suddenly break into a sweat with cold, clammy skin.

·        Nausea and vomiting. You may feel sick to your stomach or vomit.

·        Heart palpitations. You may feel as if your heart is skipping beats, or you may just be very aware that your heart is beating.

 

Heart attack symptoms can vary widely. For instance, you may have only minor chest discomfort while someone else has excruciating pain.

One thing applies to everyone, though: If you think that you're having a heart attack, immediately call 911 or your local emergency number.

If you don't have access to emergency medical services, have someone drive you to the nearest hospital. Drive yourself only if there are absolutely no other options.

Symptoms may not be dramatic

Movies and TV often portray heart attacks as dramatic, chest-clutching events. But heart attacks often begin with subtle symptoms — such as discomfort that may not even be described as pain.

It can be tempting to try to downplay the symptoms or brush them off as indigestion or anxiety. But don't "tough out" heart attack symptoms for more than five minutes. Call 911 or other emergency medical services for help.

Women may have different symptoms

Women may have many, a few or none of the typical heart attack symptoms. Some type of pain, pressure or discomfort in the chest is still a common symptom of a heart attack in women. However, many women have heart attack symptoms without chest pain. Symptoms of a heart attack in women may include:

·        Pain in the neck, back, shoulders or jaw

·        Shortness of breath

·        Stomach pain or heartburn

·        Pain in one or both arms

·        Nausea or vomiting

·        Dizziness or fainting

·        Unusual or unexplained fatigue, possibly for days

 

Older adults and people with diabetes may have no or very mild symptoms of a heart attack. Never ignore heart attack symptoms, even if they don't seem serious.

 

How to Treat a Heart Attack

Recognising the Symptoms and Calling for Help

1. Understand that sometimes there are very subtle or no warning signs. Some heart attacks are sudden and intense and provide no warning signs or tell-tale symptoms. However, in most cases, there are at least subtle clues that usually get rationalised or marginalised. Early warning signs of heart disease include high blood pressure, sensation of chronic heartburn, reduced cardiovascular fitness, and a vague feeling of malaise or being unwell. These symptoms may start many days or weeks before the heart muscle gets damaged enough to become dysfunctional.[1]

· Symptoms in women are particularly hard to recognise and are ignored or missed even more often.

· Major risk factors for heart disease, heart attack, and stroke include: high blood cholesterol levels, hypertension, diabetes, obesity, cigarette smoking and advancing age (65 years and older).

· A heart attack doesn't always lead to cardiac arrest (complete heart stoppage), but cardiac arrest is always indicative of a heart attack.

 

2.               Recognise the most common symptoms of a heart attack. Most heart attacks do not occur suddenly or "out of the blue." Instead, they typically start slowly with mild chest pain or discomfort that builds over many hours or even days. The chest pain (often described as intense pressure, squeezing or achiness) is located in the centre of the chest and can be constant or intermittent. Other common symptoms of a heart attack include: shortness of breath, cold sweats (with pale or ashen skin), dizziness or light-headedness, moderate-to-severe fatigue, nausea, abdominal pain and a sensation of severe indigestion.

· Not all people who experience heart attacks have the same symptoms or the same severity of symptoms — there's lots of variability.

· Some people also report feeling a sense of "doom" or "impending death" that is unique to the heart attack experience.

· Most people experiencing a heart attack (even a mild one) will collapse to the ground, or at least fall against something for support. Other common causes of chest pain don't typically lead to sudden collapse.

 

3.               Recognise some of the less common symptoms of a heart attack. In addition to the tell-tale symptoms of chest pain, shortness of breath, and cold sweats, there are a few common symptoms characteristic of myocardial infarction that you should be familiar with to better gauge the probability of heart failure. These symptoms include pain or discomfort in other areas of the body, such as the left arm (or sometimes both), mid-back (thoracic spine), front of the neck and/or lower jaw.

· Women are more likely than men to experience fewer common symptoms of a heart attack, particularly mid-back pain, jaw pain, and nausea/vomiting.

· Other diseases and conditions can mimic some of the symptoms of a heart attack, but the more signs and symptoms you experience, the greater the likelihood that your heart is the cause.

 

4.               Call emergency services immediately. Act immediately and call 9-1-1 or other emergency services in your area if you suspect someone is having a heart attack. Even if they don't display all or even the majority of the signs and symptoms, calling for medical help is the most important action you can take for someone in severe distress. Emergency medical services (EMS) can begin treatment as soon as they arrive and are trained to revive someone whose heart has completely stopped.

· If you can't call 9-1-1 for some reason, ask a bystander to call and give you updates as to the estimated arrival of emergency services.

· Patients with chest pain and suspected heart attack who arrive by ambulance usually receive faster attention and treatment at hospitals.

·  

 Treating Before Medical Help Arrives

 

1.    Put the person in a seated position, with knees raised. Most medical authorities recommend sitting a suspected heart attack sufferer down in the "W position" — semi-recumbent (sitting up at about 75 degrees to the ground) with knees bent. The person's back should be supported, perhaps with some pillows if at home or against a tree if outside. Once the person is in the W position, then loosen any loose clothing around his neck and chest (such as his necktie, scarf, or top buttons of his shirt) and try to keep him still and calm. You may not know what's causing his discomfort, but you can reassure him that medical help is on its way and that you'll stay with him at least until that point.

· The person should not be allowed to walk around.

· Keeping a person calm while having a heart attack is certainly a challenge, but avoid being too chatty and asking lots of irrelevant personal questions. The effort required to answer your questions may be too taxing to the person.

· While waiting for emergency help, keep the patient warm by covering him with a blanket or jacket.

 

2.               Ask the person if he carries nitroglycerine. People with a history of heart problems and angina (chest and arm pain from heart disease) are often prescribed nitroglycerine, which is a powerful vasodilator that causes large blood vessels to relax (dilate) so more oxygenated blood can reach the heart. Nitroglycerine also reduces the painful symptoms of a heart attack. People often carry their nitroglycerine with them, so ask if that's the case and then assist the person in taking it while waiting for emergency personnel to arrive. Nitro-glycerine is available as little pills or a pump spray, both of which are administered under the tongue (sublingually). The spray (Nitro lingual) reportedly is faster acting because it's absorbed quickly than the pills.

· If unsure of the dosage, administer one nitroglycerine pill or two pumps of the spray under the tongue.

· After administration of nitroglycerine, the person may become dizzy, lightheaded, or faint soon after, so make sure she is secured, sitting down, and not in danger of falling and hitting her head.

 

3.              Administer some aspirin. If you or the heart attack sufferer has any aspirin, then administer it if there's no indication of allergy. Ask the person if he has an allergy, and look for any medical bracelets on his wrists if he has trouble talking. Provided he is not younger than 18 years old, give him a 300 mg aspirin tablet to chew slowly. Aspirin is a type of non-steroidal anti-inflammatory drug (NSAID) that can reduce heart damage by "thinning" the blood, which means preventing it from clotting. Aspirin also reduces associated inflammation and helps reduce the pain of a heart attack.

· Chewing the aspirin allows the body to absorb it faster.

· Aspirin can be taken concurrently with nitroglycerin.

· A dose of 300 mg is either one adult tablet or two to four baby aspirins.

· Once at the hospital, stronger vasodilating, "clot-busting," anti-platelet and/or pain-relieving (morphine-based) drugs are given to people experiencing heart attacks.

 

4.              Initiate CPR if the person stops breathing. Cardiopulmonary resuscitation (CPR) involves chest compressions to help push some blood through the arteries (especially to the brain) combined with rescue breathing (mouth-to-mouth), which provides some oxygen to the lungs.[9] Keep in mind that CPR has its limitations and doesn't usually trigger a heart to start beating again, but it can provide some precious oxygen to the brain and buy some time before emergency services arrive with their electrical defibrillators. Regardless, take a CPR class and at least learn the basics.

· When someone starts CPR before emergency support arrives, people have a better chance of surviving a heart attack or stroke.

· People not trained in CPR should only do chest compressions and avoid rescue breathing. If the person doesn't know how to effectively deliver rescue breathing, they will simply be wasting time and energy by improperly administering breaths that are not effective.

· Keep in mind that time is very important when an unconscious person stops breathing. Permanent brain damage begins after four to six minutes without getting oxygen, and death can occur as soon as four to six minutes after enough tissue is destroyed.

 

What should I do after a heart attack?

After experiencing a heart attack, you need quick treatment to open the blocked artery and lessen the damage. At the first signs of a heart attack, call 911.

 

What procedures are used to treat a heart attack?

The procedures used to treat a heart attack include: Coronary angioplasty and stenting. This procedure is done to open clogged heart arteries and may also be called percutaneous coronary intervention (PCI). If you've had a heart attack, this procedure is often done during a procedure to find blockages (cardiac catheterisation).

 

The most common sites of myocardial infarction are in the left ventricle, that chamber of the heart which has the greatest workload.

 

A myocardial infarction may be silent and go undetected, or it could be a catastrophic event leading to hemodynamic deterioration and sudden death.

Coronary disorders

Understanding the anatomical aspects of the heart is crucial for grasping its function and the implications of various cardiovascular conditions. Here's a key point:

Structural Composition: The heart has four chambers - two atria and two ventricles. The right receives deoxygenated blood, which then goes into the right ventricle and is pumped to the lungs. Oxygen-rich blood returns to the left atrium, then goes into the left ventricle, which circulates it out to the rest of the body. This ensures the circulation of oxygenated blood throughout the body. Understanding this provides knowledge of cardiac physiology and pathology.

The coronary arteries supply oxygen-rich blood to the heart muscle. The coronary arteries originate from the base of the aorta; there are two main coronary arteries: the left coronary artery LC and the right coronary artery RC. The LAD supplies blood to the anterior wall of the left ventricle LC and a portion of the interventricular septum. The LC provides blood to the lateral wall of the left ventricle. The RC supplies blood to the right atrium, right ventricle, and a portion of the interventricular septum.

1. Distribution: The coronary arteries penetrate the heart muscle, delivering oxygen and nutrients to sustain the metabolic demands of cardiac cells.
2. Coronary Artery Disease occurs when the coronary arteries become narrowed or blocked due to plaque (atherosclerosis). This can restrict blood flow to the heart muscle, leading to ischemia and causing chest pain (angina), heart attack (myocardial infarction), or even sudden cardiac death.
3. Clinical Significance: Understanding the coronary arteries is essential for diagnosing and treating various cardiac conditions, such as coronary artery disease, myocardial infarction, and coronary artery anomalies. 

The heart performs several vital functions that are essential for sustaining life.  Key functions of the heart:

1.         Pumping Blood: 

2.         Maintaining Blood Pressure: 

3.         Circulating Oxygen and Nutrients: 

4.         Removing Waste Products: 

5.         Regulating Temperature: 

6.         Facilitating Immune Response: 

 

Overall, the heart's functions maintain homeostasis and the functioning of the body. Any disruption to its functions can have serious implications for well-being.

Coronary artery dysfunction

Coronary artery dysfunction can manifest in various forms, - atherosclerosis, the build-up of plaque within the arteries. Here are some common dysfunctions of the coronary arteries:

1. Coronary Artery Disease - Coronary Artery Spasm - Coronary Artery Dissection - Coronary Artery Anomalies:  This restricts blood flow to the heart muscle, leading to symptoms such as chest pain (angina), shortness of breath, and fatigue. Microvascular dysfunction involves abnormalities in the small blood vessels within the heart muscle. These abnormalities can impair the ability to regulate blood flow, leading to symptoms such as chest pain or discomfort. Microvascular dysfunction is more common in certain populations, such as individuals with diabetes or those with endothelial dysfunction.

 

Dysfunctions of the coronary arteries hinder proper blood flow to the heart muscle, resulting in significant health risks. These dysfunctions of the coronary arteries highlight the importance of maintaining heart health and managing risk factors such as high blood pressure, high cholesterol, diabetes, obesity, and smoking to reduce the likelihood of developing cardiovascular diseases. Regular medical check-ups and diagnostic tests can help detect these dysfunctions early and guide appropriate interventions to mitigate their impact on heart health.

Dysfunctions underlying causes. Here are the main causes:

1. Atherosclerosis - High Blood Pressure (Hypertension):  High Cholesterol Levels: 
2. Diabetes Mellitus: 
3. Smoking: 
4. Obesity and Physical Inactivity:
5. Genetic Factors: 
6. older age, family history of premature coronary artery disease, stress, poor dietary habits, excessive alcohol consumption, and certain underlying medical conditions such as chronic kidney disease or autoimmune disorders.

Understanding these causes of coronary artery dysfunction is essential for implementing preventive measures, lifestyle modifications, and targeted interventions to reduce the risk of cardiovascular events and improve overall heart health.

Care - Prevent Disorders

adopting a heart-healthy lifestyle and managing risk - reduces the likelihood of developing cardiovascular diseases. 

1. Maintain a Healthy Diet:
2. Regular Exercise:
3. Maintain a Healthy Weight:
4. Quit Smoking: 
5. Manage Stress: 
6. Control Blood Pressure: 
7. Manage Cholesterol Levels: 
8. Control Diabetes:

10. Follow Medical Advice: treatment, lifestyle modifications, and preventive care related to heart health.

This can reduce the risk of developing coronary artery disorders and improve overall cardiovascular health and well-being.

Suffering from cardiovascular disease worldwide represents a significant public health burden. The prevalence of CAD varies across different populations and is influenced by many factors such as age, sex, ethnicity, lifestyle, and socioeconomic status. 

1. CAD is contributing to a substantial number of deaths. It affects individuals of all ages, particularly with advancing age.
2. increases with age, with older adults being at higher risk. Men generally have a higher prevalence of CAD compared to premenopausal women. 
3. CAD is increasingly becoming a coin in developing countries with the adoption of Westernised lifestyles characterised by poor dietary habits, sedentary behaviour, and smoking.
4. Risk Factors: Several modifiable and non-modifiable risk factors - high blood pressure, high cholesterol, diabetes, obesity, smoking, physical inactivity, unhealthy diet, excessive alcohol consumption, and chronic stress. 
5. Prevention Efforts: promoting heart-healthy lifestyles, raising awareness about risk factors, encouraging regular medical check-ups, screening for cardiovascular risk factors, and implementing interventions to address modifiable risk factors.

Overall, coronary artery disease remains a significant health challenge worldwide, emphasising the importance of prevention, early detection, and management to reduce its burden and improve cardiovascular outcomes.

Heart Muscle Dysfunctions - Cardiomyopathy,

Overall, heart muscle dysfunctions can have significant effects on cardiac function and overall health, leading to symptoms ranging from mild to severe, life-threatening complications. Management typically involves medications, lifestyle modifications, and, in some cases, surgical interventions to alleviate symptoms, improve heart function, and reduce the risk of complications. Early diagnosis and appropriate management are crucial.

1. Dilated Cardiomyopathy (DCM):

• from a variety of factors, including genetic mutations, myocarditis, toxins (alcohol, certain drugs), autoimmune diseases, metabolic disorders, and nutritional deficiencies.
• Enlargement of the heart chambers and impaired contraction of the heart muscle. This results in decreased cardiac output, leading to symptoms such as fatigue, shortness of breath, swelling of the legs oedema, and pulmonary congestion. DCM can progress to heart failure, arrhythmias, and sudden cardiac death.

2.               Hypertrophic Cardiomyopathy (HCM):

• Hypertrophy of the heart muscle, particularly the left ventricle. This can impair the heart's ability to relax and fill with blood properly, leading to symptoms such as chest pain, shortness of breath, palpitations, fainting (syncope), and an increased risk of sudden cardiac death, particularly in young athletes.

Overall, heart muscle dysfunctions can have significant effects on cardiac function and overall health, leading to symptoms ranging from mild to severe, life-threatening complications.

Congenital Abnormalities in the Heart.

Congenital abnormalities in the heart, also known as congenital heart defects (CHDs), are structural problems with the heart that are present at birth. These defects can affect the heart's walls, valves, chambers, or blood vessels, and they vary widely in severity, ranging from mild conditions that may not require treatment to complex defects that can be life-threatening without medical intervention. Here are some common congenital heart defects:

1. Atrial Septal Defect (ASD): ASD is a hole in the wall (septum) between the heart's upper chambers (atria). This defect allows oxygen-rich blood from the left atrium to mix with oxygen-poor blood in the right atrium, leading to increased blood flow to the lungs and potential strain on the heart.
2. Ventricular Septal Defect (VSD): VSD is a hole in the wall (septum) between the heart's lower chambers (ventricles). This defect allows oxygen-rich blood from the left ventricle to mix with oxygen-poor blood in the right ventricle, leading to increased blood flow to the lungs and potential strain on the heart.
3. Tetralogy of Fallot (TOF): TOF is a complex congenital heart defect involving four abnormalities: a ventricular septal defect (VSD), pulmonary stenosis (narrowing of the pulmonary valve and artery), an overriding aorta (the aorta is shifted to the right and lies directly over the VSD), and right ventricular hypertrophy (thickening of the right ventricle). TOF can cause oxygen-poor blood to be pumped from the heart to the body, leading to cyanosis (bluish discolouration of the skin) and other symptoms.
4. Coarctation of the Aorta: Coarctation of the aorta is a narrowing of the aorta, the main artery that carries oxygen-rich blood from the heart to the body. This narrowing restricts blood flow to the lower part of the body and can lead to high blood pressure, heart failure, and other complications.
5. Transposition of the Great Arteries (TGA): TGA is a condition where the positions of the pulmonary artery and the aorta are switched. This means that oxygen-poor blood from the body is pumped back to the body without first passing through the lungs for oxygenation, and oxygen-rich blood from the lungs is pumped back to the lungs instead of being distributed to the body.
6. Hypoplastic Left Heart Syndrome (HLHS): HLHS is a rare and complex congenital heart defect where the left side of the heart (left ventricle, aorta, and mitral valve) is underdeveloped. This condition requires a series of surgeries to reroute blood flow and allow the right side of the heart to support circulation.
7. Ebstein's Anomaly: Ebstein's anomaly is a rare defect where the tricuspid valve, which separates the right atrium from the right ventricle, is malformed and positioned lower than normal. This defect can lead to blood leaking back into the right atrium and reduced blood flow to the lungs.

Treatment for congenital heart defects depends on the specific defect, its severity, and the presence of associated complications. Options may include medications, catheter-based procedures, surgical repair, or heart transplantation. With advances in medical technology and surgical techniques, many individuals with congenital heart defects can now live long and healthy lives with appropriate treatment and follow-up care.

• Transcatheter Interventions: Transcatheter interventions continue to evolve and expand, offering less invasive alternatives to traditional surgical procedures. In addition to TAVR for aortic valve replacement, transcatheter techniques are being used for mitral valve repair, closure of structural heart defects (such as atrial septal defects and patent foramen ovale), and treatment of coronary artery disease (such as percutaneous coronary interventions).
• Artificial Intelligence (AI) in Cardiology: AI and machine learning technologies are being increasingly integrated into the field of cardiology for various applications. AI algorithms can analyse medical imaging data, such as echocardiograms and cardiac MRI scans, to aid in diagnosis and treatment planning. These technologies have the potential to improve accuracy, efficiency, and personalised care in the management of heart conditions.
• Gene Therapy and Regenerative Medicine: Research into gene therapy and regenerative medicine approaches for treating heart disease is ongoing. These therapies aim to repair damaged heart tissue, promote cardiac regeneration, and improve heart function. While still in the experimental stages, these approaches hold promise for the future treatment of conditions such as heart failure and myocardial infarction.
• Remote Monitoring and Telemedicine: Remote monitoring technologies and telemedicine platforms are being increasingly utilised to manage and monitor patients with heart conditions, especially in the wake of the COVID-19 pandemic. These tools allow for remote tracking of vital signs, medication adherence, and disease progression, enabling more proactive and personalised care for patients with heart problems.

These therapies aim to restore heart function and improve the quality of life for patients with advanced heart disease.
• Remote Monitoring and Telemedicine: Remote monitoring technologies and telemedicine platforms are being utilised to monitor and manage patients with heart disease, especially in light of the COVID-19 pandemic. These tools enable remote tracking of vital signs, medication adherence, and disease progression, allowing for timely interventions and improved patient outcomes.
• Lifestyle Interventions and Prevention Programs: Emphasis on lifestyle interventions and prevention programs remains a cornerstone of heart disease management. Promoting healthy behaviours, such as regular exercise, a balanced diet, smoking cessation, and stress management, can help prevent and manage risk factors for heart disease, such as hypertension, diabetes, and obesity.
• Global Collaboration and Public Health Initiatives: International collaboration and public health initiatives play a crucial role in addressing the global burden of cardiovascular diseases. Efforts to improve access to quality healthcare, enhance public awareness, and implement evidence-based interventions can help reduce disparities in heart disease outcomes and improve population health worldwide.

Through continued innovation, collaboration, and investment in research and healthcare infrastructure, we will provide hope to mankind will be preventing, treating, and curing heart disease.

 

Congenital abnormalities in the heart.

Congenital heart defects that are present at birth, which affect the heart's walls, valves, chambers, or blood vessels, and vary widely in severity, from mild conditions that may not require treatment to complex defects that can be life-threatening. 

Here are some common congenital heart defects:

• Atrial Septal Defect (ASD): ASD is a hole in the wall (septum) between the heart's upper chambers (atria). This defect allows oxygen-rich blood from the left atrium to mix with oxygen-poor blood in the right atrium, leading to increased blood flow to the lungs and potential strain on the heart.
• Ventricular Septal Defect (VSD): VSD is a hole in the wall (septum) between the heart's lower chambers (ventricles). This defect allows oxygen-rich blood from the left ventricle to mix with oxygen-poor blood in the right ventricle, leading to increased blood flow to the lungs and potential strain on the heart.
• Tetralogy of Fallot (TOF): TOF is a complex congenital heart defect involving four abnormalities: a ventricular septal defect (VSD), pulmonary stenosis (narrowing of the pulmonary valve and artery), an overriding aorta (the aorta is shifted to the right and lies directly over the VSD), and right ventricular hypertrophy (thickening of the right ventricle). TOF can cause oxygen-poor blood to be pumped from the heart to the body, leading to cyanosis (bluish discolouration of the skin) and other symptoms.
• Coarctation of the Aorta: Coarctation of the aorta is a narrowing of the aorta, the main artery that carries oxygen-rich blood from the heart to the body. This narrowing restricts blood flow to the lower part of the body and can lead to high blood pressure, heart failure, and other complications.
• Transposition of the Great Arteries (TGA): TGA is a condition where the positions of the pulmonary artery and the aorta are switched. This means that oxygen-poor blood from the body is pumped back to the body without first passing through the lungs for oxygenation, and oxygen-rich blood from the lungs is pumped back to the lungs instead of being distributed to the body.
• Hypoplastic Left Heart Syndrome (HLHS): HLHS is a rare and complex congenital heart defect where the left side of the heart (left ventricle, aorta, and mitral valve) is underdeveloped. This condition requires a series of surgeries to reroute blood flow and allow the right side of the heart to support circulation.
• Ebstein's Anomaly: Ebstein's anomaly is a rare defect where the tricuspid valve, which separates the right atrium from the right ventricle, is malformed and positioned lower than normal. This defect can lead to blood leaking back into the right atrium and reduced blood flow to the lungs.

Treatment for congenital heart defects depends on the specific defect, its severity, and the presence of associated complications. With advances in medical technology and surgical techniques, many individuals with congenital heart defects can now live long and healthy lives.
