Quizplus · Accepted Answer

Myocardial infarction, commonly known as a heart attack, occurs when there is a blockage in the blood vessels that supply the heart, leading to ischemia (lack of oxygen) and damage to the heart muscle. Mitral stenosis is a condition where the mitral valve, which controls blood flow between the left atrium and left ventricle of the heart, narrows and restricts blood flow. Tachycardia refers to a rapid heart rate, which may or may not be related to insufficient blood supply. Anemia is a condition where there is a decrease in the number of red blood cells or hemoglobin, which can lead to poor oxygen delivery to tissues, but it is not specific to the heart.
