What is the Meaning of Myocardial Infarction?

Myocardial Infarction, commonly known as a heart attack, is the pathological event defined by ischemic necrosis of heart muscle tissue due to prolonged, severe reduction in blood supply to the myocardium. This critical event often results from the rupture of an atherosclerotic plaque leading to coronary artery thrombosis, causing irreversible cellular injury. While primarily cardiovascular, the risk profile is intimately linked to chronic endocrine imbalances, such as dyslipidemia driven by hypothyroidism or severe insulin resistance.

What is the Origin of Myocardial Infarction?

The term is derived from the Latin 'myocardium' (heart muscle) and 'infarctus' (stuffed), signifying tissue death due to obstruction of blood flow. Its study is central to cardiology, but contemporary understanding mandates evaluating systemic factors that predispose to plaque instability and thrombotic events.

What is the Mechanism of Myocardial Infarction?

The primary mechanism involves a mismatch between myocardial oxygen demand and supply, leading to cellular hypoxia and subsequent ATP depletion in cardiomyocytes. This process activates inflammatory pathways within the vessel wall, which can be exacerbated by high circulating levels of inflammatory cytokines related to visceral adiposity or chronic stress hormones. Hormonal status, particularly estrogen levels in premenopausal women, significantly influences vascular health and subsequent thrombotic risk.
