Choi et al. (2013) conducted a cohort in Variant Angina (n=686). Smoking vs. Non-smoking was evaluated on Cardiac events (recurrent chest pain, readmission, myocardial infarction, cardiac death, or need for coronary angiography) (HR 1.80, 95% CI 1.036-3.126, p=0.037). Smoking was a significant predictor of long-term cardiac events in Korean patients with variant angina (HR 1.80; 95% CI 1.036-3.126; P=0.037).
