      the coronary artery experiencing the ischemia. For example, an MI of the anterior wall is caused by ischemia in the left anterior descending coronary artery. The heart consists of three tissue layers: endocardium, myocardium, and pericardium. The endocardium, the innermost layer, lines the hearts chambers and is bathed in blood. The


    • Myocardial Infarction (Heart Attack) — STEMI vs. NSTEMI

      The term myocardial infarction refers to ischemia of the myocardial tissue due to a complete obstruction or drastic constriction of the coronary artery. This is usually accompanied by an increase in cardiac enzymes, typical ECG changes, and pain symptoms, or a thrombus or wall motion abnormality that is detected by means of medical imaging ...
