Causes of Myocardial Ischemia Myocardial ischemia occurs when blood flow to the heart muscle (myocardium) is blocked by a buildup of plaque (atherosclerosis) that partially or completely blocks the coronary arteries. If the plaque ruptures, you may have a heart attack (myocardial infarction).

Can ischemia cause myocardial infarction?

Cardiac ischemia occurs when an artery narrows or becomes blocked for a short period of time, preventing oxygen-rich blood from reaching the heart. If ischemia is severe or prolongedit can cause a heart attack (myocardial infarction) and cause the death of heart tissue.
