Values are n (%). HR indicates hazard ratio; VAMI, vasospastic angina presenting with myocardial infarction.
a
Adjusted covariates included age, sex, diabetes mellitus, hypertension, current smoker, dyslipidemia, and history of myocardial infarction.
b
Defined as a composite of cardiac death, myocardial infarction, revascularization, or rehospitalization due to recurrent angina during follow‐up.
