Prinzmetal or variant angina is a more serious type of chest pain because:
1. It indicates there is a large area of myocardial ischemia.
2. It indicates there is associated renal disease.
3. It indicates there is associated pulmonary disease.
4. It indicates the presence of a myocardial infarction.
It indicates there is a large area of myocardial ischemia.
Rationale: Variant, prinzmetal, or vasospastic angina is the most 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 a large area of the myocardium.
Prinzmetal angina does not occur due to renal disorders or pulmonary disorders, and is not specifically diagnostic for a myocardial infarction.
