Rationale 1: Variant, Prinzmetal's, or vasospastic angina is a serious type of angina. It occurs when single or multiple sites in major coronary arteries and their large branches have vasospasm, thereby cutting off the blood supply to an area of the myocardium.
Rationale 2: Prinzmetal's angina is not linked to renal disorders.
Rationale 3: Prinzmetal's angina is not linked to pulmonary disorders.
Rationale 4: Prinzmetal's angina is not specifically diagnostic for myocardial infarction.
