What is the term for the blockage of one or more coronary arteries leading to a heart attack?

The term for the blockage of one or more coronary arteries leading to a heart attack is "Myocardial Infarction." This condition occurs when the blood flow to a part of the heart muscle is obstructed, typically due to a buildup of plaque or a blood clot in the coronary arteries. As a result, the affected heart tissue becomes deprived of oxygen and nutrients, leading to tissue damage or death. The term "myocardial" refers specifically to the heart muscle, while "infarction" denotes the death of tissue due to lack of blood supply.

In contrast, other terms listed refer to different conditions. Cardiac arrest describes a sudden cessation of heart function, which is not directly indicative of blockage in coronary arteries. Cerebral infarction pertains to a similar blockage occurring in the blood vessels supplying the brain, leading to a stroke. Coronary thrombosis refers to the presence of a blood clot in a coronary artery but does not encompass the broader implications and results of that blockage as comprehensively as myocardial infarction.
