What is the Origin of Myocardial Infarction?

The term is derived from the Greek myo- (muscle), kardia (heart), and the Latin infarcire (to stuff or plug up), referring to the plugging of a blood vessel leading to tissue death. This specific clinical diagnosis became clearly defined with advancements in cardiology and pathology in the 20th century.

What is the Mechanism of Myocardial Infarction?

The pathological mechanism begins with the rupture of a vulnerable plaque within a coronary artery, triggering a thrombotic cascade that forms a clot. This thrombus completely blocks blood flow, depriving the downstream myocardial tissue of oxygen and nutrients. Without prompt reperfusion, the resulting cellular hypoxia leads to energy depletion, structural damage, and ultimately, cell death, compromising the heart's pumping function.

Myocardial Infarction

Meaning

Myocardial infarction, commonly known as a heart attack, is a severe clinical event characterized by the irreversible necrosis, or death, of a portion of the heart muscle due to prolonged ischemia, which is a lack of adequate blood supply. This critical condition is typically caused by the occlusion of a coronary artery, often due to a ruptured atherosclerotic plaque. In hormonal health, systemic inflammation and hormonal dysregulation, such as low testosterone or high cortisol, are recognized risk factors for this cardiovascular event.
