  Myocardial infarction (MI), commonly referred to as a "heart attack," occurs when blood flow to a portion of the myocardium is significantly reduced or completely obstructed. Smoking and an abnormal apolipoprotein ratio demonstrate the strongest correlation with myocardial infarction. Additional risk factors include moderately elevated plasma homocysteine levels, independently increasing the risk of MI. Acute occlusion of one or more large epicardial coronary arteries for a duration exceeding 20 to 40 minutes can precipitate acute myocardial infarction, typically resulting from thrombotic occlusion following plaque rupture in the coronary arteries. This occlusion leads to myocardial oxygen deprivation, causing sarcolemmal disruption and myofibril relaxation, representing among the initial ultrastructural changes in the progression of MI, followed by mitochondrial alterations. Evaluation of MI involves assessing clinical features, ECG findings, and cardi...
