Question: What is (are) Heart Attack ?
Answer: Blood Flow to the Heart Is Blocked The heart works 24 hours a day, pumping oxygen and nutrient-rich blood to the body. Blood is supplied to the heart through its coronary arteries. If a blood clot suddenly blocks a coronary artery, it cuts off most or all blood supply to the heart, and a heart attack results. If blood flow isn't restored quickly, the section of heart muscle begins to die. The more time that passes without treatment to restore blood flow, the greater the damage to the heart. Affects Both Men and Women Heart attacks are a leading killer of both men and women in the United States. Each year, more than one million people in the U.S. have a heart attack and about half of them die. Half of those who die do so within one hour of the start of symptoms and before reaching the hospital. The good news is that excellent treatments are available for heart attacks. These treatments can save lives and prevent disabilities. Prompt Treatment Is Important Heart attack treatment works best when it's given right after symptoms occur. Prompt treatment of a heart attack can help prevent or limit damage to the heart and prevent sudden death. Call 9-1-1 Right Away A heart attack is an emergency. Call 9-1-1 for an ambulance right away -- within 5 minutes -- if you think you or someone else may be having a heart attack. You also should call for help if your chest pain doesn't go away as it usually does when you take medicine prescribed for angina (chest pain). Do not drive to the hospital or let someone else drive you. Emergency personnel in the ambulance can begin life-saving treatment on the way to the emergency room. They carry drugs and equipment that can help your medical condition, including - oxygen - aspirin to prevent further blood clotting - heart medications, such as nitroglycerin - pain relief treatments - defibrillators that can restart the heart if it stops beating. oxygen aspirin to prevent further blood clotting heart medications, such as nitroglycerin pain relief treatments defibrillators that can restart the heart if it stops beating. If blood flow in the blocked artery can be restored quickly, permanent heart damage may be prevented. Yet, many people do not seek medical care for 2 hours or more after symptoms start.

Question: What causes Heart Attack ?
Answer: Most heart attacks are caused by a blood clot that blocks one of the coronary arteries, the blood vessels that bring blood and oxygen to the heart muscle. When blood cannot reach part of your heart, that area starves for oxygen. If the blockage continues long enough, cells in the affected area die. The Most Common Cause Coronary heart disease (CHD)is the most common underlying cause of a heart attack. CHD, also called coronary artery disease, is the hardening and narrowing of the coronary arteries caused by the buildup of plaque inside the walls of the arteries. When plaque builds up in the arteries, the condition is called atherosclerosis (ath-er-o-skler-O-sis). The buildup of plaque occurs over many years. Over time, an area of plaque can rupture (break open) inside of an artery. This causes a blood clot to form on the plaque's surface. If the clot becomes large enough, it can mostly or completely block blood flow through a coronary artery. If the blockage isn't treated quickly, the portion of heart muscle fed by the artery begins to die. Healthy heart tissue is replaced with scar tissue. This heart damage may not be obvious, or it may cause severe or long-lasting problems. Other Causes Heart attack also can occur due to problems with the very small, microscopic blood vessels of the heart. This condition is called microvascular disease. It's believed to be more common in women than in men. A less common cause of heart attacks is a severe spasm or tightening of the coronary artery that cuts off blood flow to the heart. These spasms can occur in persons with or without coronary artery disease. What causes a coronary artery to spasm isn't always clear. A spasm may be related to emotional stress or pain, exposure to extreme cold, cigarette smoking, or by taking certain drugs like cocaine. Risk Factors You Cannot Change Certain factors make it more likely that you will develop coronary artery disease and have a heart attack. These risk factors include some things you cannot change. If you are a man over age 45 or a woman over age 55, you are at greater risk. Having a family history of early heart disease, diagnosed in a father or brother before age 55 or in a mother or sister before age 65, is another risk factor. You are also at risk if you have a personal history of angina or previous heart attack, or if you have had a heart procedure such as percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG). Risk Factors You Can Change Importantly, there are many risk factors that you can change. These include - smoking - being overweight or obese - physical inactivity - high blood pressure - high blood cholesterol - high blood sugar due to insulin resistance or diabetes - an unhealthy diet (for example, a diet high in saturated fat, trans fat, cholesterol, and sodium). smoking being overweight or obese physical inactivity high blood pressure high blood cholesterol high blood sugar due to insulin resistance or diabetes an unhealthy diet (for example, a diet high in saturated fat, trans fat, cholesterol, and sodium). Metabolic Syndrome Some of these risk factorssuch as obesity, high blood pressure, and high blood sugartend to occur together. When they do, it's called metabolic syndrome. In general, a person with metabolic syndrome is twice as likely to develop heart disease and five times as likely to develop diabetes as someone without metabolic syndrome.

Question: Who is at risk for Heart Attack? ?
Answer: Lowering your risk factors for coronary heart disease (CHD) can help you prevent a heart attack. Even if you already have CHD or have already had a heart attack, you can still take steps to lower your risk. These steps involve following a heart healthy lifestyle and getting ongoing care for conditions that raise your risk. Heart Healthy Lifestyle Changes You can make these lifestyle changes to lower your risk of having a heart attack. - If you smoke, quit. - Maintain a healthy weight. - Be as physically active as you can. - Follow a heart healthy diet. If you smoke, quit. Maintain a healthy weight. Be as physically active as you can. Follow a heart healthy diet. If you smoke, quit. Smoking can raise your risk of CHD and heart attack. Talk with your doctor about programs and products that can help you quit. Also, try to avoid secondhand smoke. Maintain a healthy weight. If you're overweight or obese, work with your doctor to create a reasonable weight-loss plan that involves diet and physical activity. Controlling your weight helps you control risk factors for coronary heart disease (CHD) and heart attack. Be as physically active as you can. Physical activity can improve your fitness level and your health. Talk with your doctor about what types of activity are safe for you. Follow a heart healthy diet. Following a healthy diet is an important part of a heart healthy lifestyle. Eat a healthy diet to prevent or reduce high blood pressure and high blood cholesterol, and to maintain a healthy weight. A healthy diet includes a variety of fruits, vegetables, and whole grains. It also includes lean meats, poultry, fish, beans, and fat-free or low-fat milk or milk products. A healthy diet is low in saturated fat, trans fat, cholesterol, sodium (salt), and added sugars.

Question: How to diagnose Heart Attack ?
Answer: If You Have Symptoms, Call 9-1-1 Diagnosis and treatment of a heart attack can begin when emergency personnel arrive after you call 9-1-1. Do not put off calling 9-1-1 because you are not sure that you are having a heart attack. Call within 5 minutes of the start of symptoms. At the hospital emergency room, doctors will work fast to find out if you are having or have had a heart attack. They will consider your symptoms, medical and family history, and test results. Initial tests will be quickly followed by treatment if you are having a heart attack. Diagnostic Tests - an electrocardiogram - blood tests - nuclear heart scan - cardiac catheterization - and coronary angiography. an electrocardiogram blood tests nuclear heart scan cardiac catheterization and coronary angiography. The electrocardiogram, also known as ECG or EKG, is used to measure the rate and regularity of your heartbeat. Blood tests are also used in diagnosing a heart attack. When cells in the heart die, they release enzymes into the blood. They are called markers or biomarkers. Measuring the amount of these markers in the blood can show how much damage was done to your heart. Doctors often repeat these tests to check for changes. The nuclear heart scan uses radioactive tracers to outline the heart chambers and major blood vessels leading to and from the heart. A nuclear heart scan shows any damage to your heart muscle as well as how well blood flows to and from the heart. In cardiac catheterization, a thin, flexible tube is passed through an artery in your groin or arm to reach the coronary arteries. This test allows your doctor to - determine blood pressure and flow in the heart's chambers - collect blood samples from the heart, and - examine the arteries of the heart by x-ray. determine blood pressure and flow in the heart's chambers collect blood samples from the heart, and examine the arteries of the heart by x-ray. Coronary angiography is usually done with the cardiac catheterization. A dye that can be seen on an x-ray is injected through the catheter into the coronary arteries. It shows where there are blockages and how severe they are.

Question: What are the treatments for Heart Attack ?
Answer: If you are having a heart attack, doctors will work quickly to restore blood flow to the heart and continuously monitor vital signs to detect and treat complications. Restoring blood flow to the heart can prevent or limit damage to the heart muscle and help prevent another heart attack. Doctors may use clot-busting drugs called thrombolytics and procedures, such as angioplasty. Long-term treatment after a heart attack may include cardiac rehabilitation, checkups and tests, lifestyle changes, and medications.

Question: What is (are) Heart Attack ?
Answer: Angina is a recurring pain or discomfort in the chest that happens when some part of the heart does not receive enough blood. An episode of angina is not a heart attack. However, people with angina may have a hard time telling the difference between angina and heart attack symptoms. Angina is chest pain or discomfort that occurs when your heart muscle does not get enough blood. Angina may feel like pressure or a squeezing pain in your chest. The pain may also occur in your shoulders, arms, neck, jaw, or back. It may also feel like indigestion. It is usually relieved within a few minutes by resting or by taking prescribed angina medicine.
