The basic pathophysiology of myocardial infarction is best described as:

a) cardiac output that is insufficient to meet the needs of the heart and body.
b) temporary vasospasm that occurs in a coronary artery.
c) total obstruction of a coronary artery, which causes myocardial necrosis.
d) irregular heart rate and force, reducing blood supply to coronary arteries.

Option C - total obstruction of a coronary artery, which causes myocardial necrosis.

Explanation:

MYOCARDIAL INFARCTION is the necrosis (death of tissues) of heart muscle caused by an interruption to the supply of blood to the heart, often as a result of coronary thrombosis (blockage caused by blood clot).

So, the basic pathophysiology of myocardial infarction is TOTAL OBSTRUCTION of the coronary artery by blood clot, resulting in myocardial necrosis
