Acute myocardial infarction: what it is and what are the possible causes. When curing with the stent

Heart attack (or acute myocardial infarction) it occurs when one of the coronary arteries, which supply blood to the heart muscle, becomes blocked. A “plug” (atherosclerotic plaque) forms in one of the coronary arteries and blocks the flow of blood: if the occlusion lasts long enough, the portion of the heart downstream of the artery remains without oxygen and undergoes necrosis, i.e. its cells die.
