Variant angina pectoris in the elderly

Variant angina pectoris is a type of spontaneous angina pectoris. In 1959, Prinzmetal et al. Named ischemic angina pectoris caused by coronary spasm as variant angina pectoris, and pointed out that the onset of angina pectoris had nothing to do with the activity. The pain occurred at rest, the ST segment increased during the episode, and the ST segment decreased after the episode. A pathological Q wave appears. The pain is mainly caused by coronary spasm, and more myocardial infarction and death occur within six months.
