Quizplus · Accepted Answer

Angina pectoris is caused by reduced blood flow to the heart due to temporary narrowing or spasm of the coronary arteries. This results in chest pain or discomfort. Pericarditis is inflammation of the pericardium, the sac surrounding the heart, and is not caused by deficient blood delivery. Myocardial infarction (MI), commonly known as a heart attack, is caused by complete or near-complete blockage of the coronary artery, leading to damage or death of heart muscle tissue. Ischemia refers to insufficient blood supply to an organ, typically due to narrowing or blockage of a blood vessel, which can lead to a range of problems including angina pectoris and MI.
