Heart Attack (Myocardial Infarction) A heart attack, known medically as a myocardial infarction, occurs when a blood clot blocks one of the coronary arteries. Each coronary artery supplies blood to a specific part of the heart's muscular wall, so a blockage causes pain and malfunction in the area that the affected artery serves.

Understanding Heart Attack: The Basics The heart has three coronary arteries, two of them large, branching arteries that deliver oxygenated blood to the heart muscle. If one of these arteries or branches becomes blocked suddenly, a portion of the heart is starved of oxygen, a condition called cardiac ischemia. If cardiac ischemia lasts too long, the starved heart tissue dies. This is a heart attack, otherwise known as a myocardial infarction -- literally, death of heart muscle.

ischemia Myocardial ischemia is an intermediate condition in coronary artery disease during which the heart tissue is slowly or suddenly starved of oxygen and other nutrients. Eventually, the affected heart tissue will die.

Ischemia - Topic Overview What is ischemia? Ischemia is the medical term for what happens when your heart muscle doesn't get enough oxygen. Ischemia usually happens because of a shortage of blood and oxygen to the heart muscle. It is usually due to narrowing or blockage of one or more of the coronary arteries (which supply blood to the heart muscle). In many cases ischemia is a temporary problem. Your heart may be ...

Overview Acute coronary syndrome is a term used to describe a range of conditions associated with sudden, reduced blood flow to the heart. One condition under the umbrella of acute coronary syndrome is myocardial infarction (heart attack) — when cell death results in damaged or destroyed heart tissue. Even when acute coronary syndrome causes no cell death, the reduced blood flow alters heart function and indicates a high risk of heart attack.

acute myocardial infarction acute myocardial infarction (AMI) the early critical stage of necrosis of heart muscle tissue caused by blockage of a coronary artery. It is characterized by elevated S-T segments in the reflecting leads and elevated levels of cardiac enzymes. See also myocardial infarction.

- Acute myocardial infarction (MI) is the most common cause of cardiogenic shock and is defined as a clinical event consequent to the death of cardiac myocytes (myocardial necrosis) that is caused by ischemia (as opposed to other etiologies such as myocarditis or trauma).

In this condition, the left ventricle, which is the main heart muscle, is usually enlarged and dilated.This condition can be a result of a heart attack or coronary artery disease, a narrowing of the arteries.n this condition, the left ventricle, which is the main heart muscle, is usually enlarged and dilated.

Acronyms &Abbreviations Myocardial ischemia is an imbalance between myocardial oxygen supply and demand. Left untreated, it results in angina pectoris, myocardial stunning, myocardial hibernation, ischemic preconditioning, postconditioning, or under the most severe instances, acute coronary syndrome and myocardial infarction.

Myocardial infarction For other uses, see Heart attack (disambiguation). Myocardial infarction (MI) or acute myocardial infarction (AMI), commonly known as a heart attack, occurs when blood flow stops to a part of the heart causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw.

Silent Ischemia Related terms: ischemia, restricted blood flow. Ischemia is a condition where the flow of oxygen-rich blood to a part of the body is restricted. Cardiac ischemia refers to lack of blood flow and oxygen to the heart muscle. Cardiac ischemia happens when an artery becomes narrowed or blocked for a short time, preventing oxygen-rich blood from reaching the heart.

Ischemic Cardiomyopathy: Symptoms, Causes, and Treatment Ischemic cardiomyopathy (IC) is a condition when your heart muscle is weakened as a result of a heart attack or coronary artery disease. In coronary artery disease, the arteries that supply blood to your heart muscle become narrowed. This can keep necessary blood from reaching portions of your heart muscle, causing damage.
