Final answer:
Myocardial infarction (MI) is a condition characterized by ischemic and infarct of the interior lateral myocardium. It occurs when there is a lack of blood flow and oxygen to a region of the heart, resulting in the death of cardiac muscle cells.
Step-by-step explanation:
A condition characterized by ischemic and infarct of the interior lateral myocardium is known as myocardial infarction (MI). It occurs when there is a lack of blood flow and oxygen to a region of the heart, leading to the death of cardiac muscle cells.
Myocardial infarction typically occurs when a coronary artery is blocked by the buildup of atherosclerotic plaque, which consists of lipids, cholesterol, fatty acids, and white blood cells. This blockage restricts the flow of blood and oxygen to the myocardium, causing tissue death.
Excessive exercise or severe stress can trigger myocardial infarction when the partially occluded artery is unable to pump enough blood or due to spasms of the smooth muscle in the vessel walls.
