Myocardial infarction happens unexpectedly, and it occurs because of a disturbance of the blood supply to a certain part of the heart muscle. This acute condition causes problems with all organs of the cardiovascular system and poses a real threat to life.
Insufficient blood supply to the heart muscle (or rather, to the heart middle layer, myocardium) is the main reason of this acute condition. It can occur due to atherosclerosis, which is characterized by the appearance of plaques on the vascular walls that prevent proper blood circulation.
