Myocardial Ischemia

Myocardial ischemia (pronounced: my-o-CAR-dee-ul is-KEE-me-uh) is a medical condition characterized by reduced blood flow to the heart muscle, often due to a partial or complete blockage of the heart's arteries.

Etymology

The term "myocardial ischemia" is derived from the Greek words "myo" meaning muscle, "cardia" meaning heart, and "ischemia" meaning deficiency of blood.

Definition

Myocardial ischemia occurs when blood flow to the heart muscle (myocardium) is obstructed by a partial or complete blockage of a coronary artery by a buildup of plaques (atherosclerosis). This can damage or destroy part of the heart muscle.

Symptoms

Symptoms of myocardial ischemia can include chest pain (angina), shortness of breath, fatigue, and irregular heartbeat (arrhythmia). However, some people with myocardial ischemia may not have any symptoms, a condition known as silent ischemia.

Diagnosis

Diagnosis of myocardial ischemia involves a variety of tests, including electrocardiogram (ECG), stress tests, echocardiogram, and coronary angiogram.

Treatment

Treatment for myocardial ischemia aims to improve blood flow to the heart muscle. This can be achieved through lifestyle changes, medications, and in some cases, surgical procedures such as angioplasty and coronary artery bypass surgery (CABG).
