What is a heart attack?

A heart attack happens when a sudden blockage in one of your coronary arteries cuts off the blood supply to your heart muscle. If a tear or rupture develops in a plaque that has built up in your coronary artery as a result of atherosclerosis, a blood clot can form on the torn plaque, just as a blood clot forms when you cut your skin. This clot can completely block the artery and cut off the blood supply to a portion of your heart muscle. Without blood, your heart muscle doesn't get oxygen, and without oxygen, the muscle can die.

The medical term for a heart attack is a myocardial infarction. "Myocardial" refers to your heart muscle, and "infarction" refers to the permanent damage to your heart muscle that results from a heart attack.

Many people live with coronary artery disease (CAD) and never have a heart attack. It's important to understand, however, that a heart attack can occur suddenly even in someone who has never had symptoms of CAD before. If you have plaque in your coronary arteries from atherosclerosis, you can have a heart attack. In fact, some people first learn that they have CAD when they have a heart attack. These people likely had CAD for many years but did not know it because it did not cause any symptoms.

What does a heart attack feel like?

The symptoms of a heart attack are similar to the symptoms of a type of chest pain called angina. Most people who have a heart attack experience some form of chest pain or discomfort that is often described as tightness, heaviness, squeezing, or crushing in the chest. Heart attacks also cause other related symptoms, such as difficulty breathing, nausea, and sweating. If you have had angina before, you will probably find that the symptoms of a heart attack are more intense and last longer than the symptoms of angina. A heart attack can happen during exertion or even while you are resting.

These symptoms can also be from unstable angina, a severe form of angina that means you have a greater risk of having a heart attack. When you go to the hospital, your doctor will have to determine whether you are having a heart attack or an episode of unstable angina.

What should I do if I think I am having a heart attack?

Call 911 or other emergency services immediately if you have any symptoms that suggest unstable angina or a heart attack. If you are having a heart attack, every minute counts. The longer you wait, the greater the chance that your heart will be permanently damaged or that you might die from the heart attack.

Will I die from a heart attack?

Your chances of dying from a heart attack depend on the size of your heart attack, the part of your heart that is affected, and your overall health. The other important factor is how quickly you are able to get medical attention after your heart attack begins. The longer your heart muscle is deprived of oxygen, the more the heart attack will damage your heart.

Your chances of dying from a heart attack also increase if your heart attack causes serious problems with your heart or with other parts of your body, such as heart failure or a stroke. The more problems that your heart attack causes, the worse your chances of survival are.

Statins may worsen heart failure for some

Wednesday, November 4, 2009 (canstar) - it is well known that cholesterol-lowering statins may benefit patients with heart disease, but a new study suggests that they can to harm some people with heart failure.

Heart disease can occur when arteries become clogged, but in heart failure, the heart gets progressively more weak and larger.

Still, since the study included a small number of patients and looked at a single point in time, it is too early to say if the findings have implications for heart failure patients taking statins, according to the principal of Lawrence P. Cahalin, PhD, of Northeastern University, Boston. Cahalin presented his findings Tuesday at the American College of Chest Physicians in San Diego annual meeting.

Tamara Horwich, MD, assistant professor of medicine at the University of California at Los Angeles, accepts that the results should be interpreted with caution. I just don "t think we can draw conclusions about Statins have benefits to the adverse effects in some patients," says Dr. Horwich, who was not involved in the study of the Cahalin.

In heart failure, the struggles of hypertrophy of the heart to pump enough blood, which can cause fluid to collect in branches and the lungs, resulting in shortness of breath and fatigue. However, one type of failure heart, systolic, occurs when the lower chambers of the heart may conclude a contract with sufficient force to blood drive in the body.

In the other type, diastolic heart failure, cardiac muscle is so rigid that it can relax is no longer enough to fill with blood between beats. About half of people with heart failure have systolic; the other half have diastolic, which becomes more common with age and is more likely to strike women.

About 5 million Americans have heart failure.

Currently, there is no guidelines on the question of whether patients with heart failure should take statins. Some studies have shown that they can be useful, while others have found no benefit. The decision to prescribe these drugs is generally based on the patient's cholesterol levels, age, and if there also coronary heart disease, according to Dr. Horwich.

"It is not a consensus," she said. "It is the physician individual to make a decision."

If it persists, fibrillation atrial ups your chances of a stroke.

Misfortunes of extra money coupled with already stressful Christmas can also be a Setup for overindulgence. "People do not have much money, but they still need to spend," said Gerald Fletcher, MD, a cardiologist at the clinic in Rochester, Minnesota Mayo "they are reduce, but they are concerned about the credit card bill on the path."
