Prinzmetal’s or Prinzmetal angina (/ˈprɪntsmɛtəl/ sounds like prints metal) (also known as variant angina angina inversa or coronary vessel spasm) is a syndrome typically consisting of angina (cardiac chest pain) at rest that occurs in cycles. It is caused by vasospasm a narrowing of the coronary arteries caused by contraction of the smooth muscle tissue in the vessel walls rather than directly by atherosclerosis (buildup of fatty plaque and hardening of the arteries).
