Myocardial infarction or heart attack it is a life threatening emergency.
It presents itself when, following the rupture of an atherosclerotic plaque, a blood clot occludes a coronary artery.
The obstruction of the artery prevents blood from providing oxygen to the affected region of the heart. As a consequence, this cardiac region loses its ability to contract and pump blood. Without an immediate intervention, it risks being permanently damaged.
