what is the major causes of heart attack?
Heart attacks most often result from coronary heart disease (also called coronary artery disease or ischemic heart disease). The most common cause is atherosclerosis ("hardening of the arteries"), a build-up of fatty deposits called plaque. Over time, plaque clogs and narrows the arteries and other blood vessels, and slows or blocks the flow of blood to the heart and elsewhere. Sometimes, the surface of plaques can rupture or tear, which can cause blood clots to form that block the arteries. A complete or near-complete blockage of the coronary arteries results in a heart attack. The signs and symptoms of a heart attack vary from person to person: # An intense aching in the left side or center of the chest Sometimes, the pain radiates into the neck, back, arms or jaw # A feeling of extreme pressure, fullness, or tightness in the chest # Nausea, dizziness, weakness, shortness of breath, or a cold sweat also can be experienced. These are the main symtoms.

Hello. It is a nice post and the information is nice. Thanks for sharing. This information is important for everyone. In my opinion heart attach occur due to smoke. We can prevent from heart attacks with eating clean and healthy food.

Hi Annie,
Thanks for sharing major causes of heart attack with everyone. Some more reasons of heart attack are:
Lack of exercising,
Smoking,
Drinking alcohol,
Eating too much saturated fat,
Taking too much stress,
Not having enough fruits and vegetables.

There are many things that effect your heart and if it has an attack (Myocardial infarction (posh word for heart attack)).
1. Food-the more fatty food u eat the more fat u have and your hearth slows down bit by bit.
2.Shocking-if u get shocked a lot like your friends comes behind and surprise your heart jumps fast which is not really good.
3. emotion-if u get angry and being aggressive a lot your heart will feel the same to cuz is part of you.
4. Alcohol - As per studies daily intake of small amount of alcohol increases the production of HDL(High density lipo proteins-good cholesterol).
5. Diabetes increases the process of arteriosclerosis in heart blood vessels and increases the possibility.Patient who are suffering from diabetes and heart attack precipitation should be watched carefully.Because diabetes patient may not have chest pain in attack(silent heart attack symptoms) is also a high risk factor in treating the diabetic heart attack patients.

High Blood Pressure (Hypertension). High blood pressure increases your risk of heart disease, heart attack, and stroke. Though other risk factors can lead to high blood pressure, you can have it without having other risk factors. If you are obese, you smoke, or you have high blood cholesterol levels along with high blood pressure, your risk of heart disease or stroke greatly increases.
Blood pressure can vary with activity and with age, but a healthy adult who is resting generally has a systolic pressure reading between 120 and 130 and a diastolic pressure reading between 80 and 90 (or below).
High Blood Cholesterol. One of the major risk factors for heart disease is high blood cholesterol. Cholesterol, a fat-like substance carried in your blood, is found in all of your body's cells. Your liver produces all of the cholesterol your body needs to form cell membranes and to make certain hormones. Extra cholesterol enters your body when you eat foods that come from animals (meats, eggs, and dairy products).
Although we often blame the cholesterol found in foods that we eat for raising blood cholesterol, the main culprit is the saturated fat in food. (Be sure to read nutrition labels carefully, because even though a food does not contain cholesterol it may still have large amounts of saturated fat.) Foods rich in saturated fat include butter fat in milk products, fat from red meat, and tropical oils such as coconut oil.
Too much low-density lipoprotein (LDL or "bad cholesterol") in the blood causes plaque to form on artery walls, which starts a disease process called atherosclerosis. When plaque builds up in the coronary arteries that supply blood to the heart, you are at greater risk of having a heart attack.
Diabetes. Heart problems are the leading cause of death among people with diabetes, especially in the case of adult-onset or Type II diabetes (also known as non-insulin-dependent diabetes). Certain racial and ethnic groups (African Americans, Hispanics, Asian and Pacific Islanders, and Native Americans) have a greater risk of developing diabetes. The American Heart Association estimates that 65% of patients with diabetes die of some form of cardiovascular disease. If you know that you have diabetes, you should already be under a doctor's care, because good control of blood sugar levels can reduce your risk. If you think you may have diabetes but are not sure, see your doctor for tests.
Obesity and Overweight. Extra weight is thought to lead to increased total cholesterol levels, high blood pressure, and an increased risk of coronary artery disease. Obesity increases your chances of developing other risk factors for heart disease, especially high blood pressure, high blood cholesterol, and diabetes.
Many doctors now measure obesity in terms of body mass index (BMI), which is a formula of kilograms divided by height in meters squared (BMI =W [kg]/H [m2]). According to the National Heart, Lung, and Blood Institute (NHLBI), being overweight is defined as having a BMI over 25. Those with a number over 30 are considered obese.
Smoking. Most people know that cigarette and tabacco smoking increases your risk of lung cancer, but fewer realize that it also greatly increases your risk of heart disease and peripheral vascular disease (disease in the vessels that supply blood to the arms and legs). According to the American Heart Association, more than 400,000 Americans die each year of smoking-related illnesses. Many of these deaths are because of the effects of smoking on the heart and blood vessels.
Research has shown that smoking increases heart rate, tightens major arteries, and can create irregularities in the timing of heartbeats, all of which make your heart work harder. Smoking also raises blood pressure, which increases the risk of stroke in people who already have high blood pressure. Although nicotine is the main active agent in cigarette smoke, other chemicals and compounds like tar and carbon monoxide are also harmful to your heart in a variety of ways. These chemicals lead to the buildup of fatty plaque in the arteries, possibly by injuring the vessel walls. And they also affect cholesterol and levels of fibrinogen, which is a blood-clotting material. This increases the risk of a blood clot that can lead to a heart attack.
Physical Inactivity. People who are not active have a greater risk of heart attack than do people who exercise regularly. Exercise burns calories, helps to control cholesterol levels and diabetes, and may lower blood pressure. Exercise also strengthens the heart muscle and makes the arteries more flexible. Those who actively burn 500 to 3500 calories per week, either at work or through exercise, can expect to live longer than people who do not exercise. Even moderate-intensity exercise is helpful if done regularly.
Gender. Overall, men have a higher risk of heart attack than women. But the difference narrows after women reach menopause. After the age of 65, the risk of heart disease is about the same between the sexes when other risk factors are similar.
Heredity. Heart disease tends to run in families. For example, if your parents or siblings had a heart or circulatory problem before age 55, then you are at greater risk for heart disease than someone who does not have that family history. Risk factors (including high blood pressure, diabetes, and obesity) may also be passed from one generation to another.
Also, researchers have found that some forms of cardiovascular disease are more common among certain racial and ethnic groups. For example, studies have shown that African Americans have more severe high blood pressure and a greater risk of heart disease than whites. The bulk of cardiovascular research for minorities has focused on African Americans and Hispanics, with the white population used as a comparison. Risk factors for cardiovascular disease in other minority groups are still being studied.
Age. Older age is a risk factor for heart disease. In fact, about 4 of every 5 deaths due to heart disease occur in people older than 65.
As we age, our hearts tend to not work as well. The heart's walls may thicken, arteries may stiffen and harden, and the heart is less able to pump blood to the muscles of the body. Because of these changes, the risk of developing cardiovascular disease increases with age. Because of their sex hormones, women are usually protected from heart disease until menopause, and then their risk increases. Women 65 and older have about the same risk of cardiovascular disease as men of the same age.
