Effect of cigarette smoking on survival of patients with angiographically documented coronary artery disease: report from the CASS registry
Through a multicenter registry of patients in the Coronary Artery Surgery Study, the author prospectively evaluated morbidity and mortality in 4165 smokers with angiographically proved coronary artery disease, 2675 of whom continued to smoke and 1490 of whom quit. At five years, mortality was 22% for those who continued smoking and 15% for quitters. The relative risk for mortality in continuers vs quitters was 1.55. The adverse effect of smoking mainly took the form of higher frequencies of myocardial infarction-associated death and sudden death: the frequencies of these events during follow-up in continuers vs quitters were 7.9% vs 4.4% for myocardial infarction-associated death and 2.8% vs 1.5% for sudden death. This study supports the recommendation that patients with coronary artery disease should stop smoking.
