Abstract

OBJECTIVE: To identify factors predictive of smoking cessation after successful percutaneous coronary revascularization. MATERIAL & METHODS: We undertook a case-control study of the smoking status of all patients at Mayo ClinicRochester from September 1979 through December 1995 who were smokers at the time of an index percutaneous coronary revascularization procedure in the nonperi-infarction setting (no inyocardial infarction within 24 hours). Maximal duration of prospective follow-up was 16 years. Patients were classified into those who permanently quit smoking immediately after the procedure (n = 435; mean follow-up, 5.1 ±3.7 years) or those who continued to smoke at some time during follow-up (n = 734; mean follow-up, 5.3 ±3.7 years). Logistics regression models were formulated to determine independent predictors of smoking cessation. RESULTS: Predictors ot continued smoking were greater prior cigarette consumption (odds ratio (OR] = 1.009 for each pack-year; 95% confidence interval [CI] = 1.004 to 1.014) and having one or more risk factors for coronary artery disease other than cigarette smoking (OR = 1.49; 95% CI = 1.15 to 1.93). Older age (OR = 0.98 for each additional year; 95% Cl = 0.97 to 0.99) and unstable angina at time of initial assessment (OR = 0.69; 95% CI = 0.52 to 0.91 ) were associated with less likelihood of continued smoking. CONCLUSION: Younger patients with a worse risk profile and greater prior cigarette consumption were more likely than other patients to continue smoking after percutaneous coronary revascularization in the nonperi-infarction setting. Patients who had unstable angina were more likely to quit smoking than those who had stable angina. Despite the proven benefits of smoking cessation after percutaneous coronary revascularization, a substantial proportion of smokers (63%) continue to smoke: thus, smoking-cessation counseling should be addressed in this population.
