Current Smoking, Smoking Cessation, and the Risk of Sudden Cardiac Death in Patients With Coronary Artery Disease

Goldenberg, Ilan·2003·Archives of Internal Medicine

Abstract

BACKGROUND: Cigarette smoking is a known risk factor for sudden cardiac death (SCD). However, the effect of continued cigarette smoking and smoking cessation on SCD risk in patients with established coronary artery disease (CAD) is subject to controversy. We, therefore, evaluated the effect of cigarette smoking on SCD risk in a large cohort of patients with established CAD. METHODS: The study population was composed of 3122 patients with a previous myocardial infarction or stable angina who participated in the Bezafibrate Infarction Prevention Trial. Patients were prospectively followed up for a mean of 8.2 years. The primary end point was the incidence of SCD according to smoking status. RESULTS: Among the 370 patients who were current smokers, 30 (8.1%) experienced SCD; 83 (4.6%) of the 1821 patients who had quit smoking and 43 (4.6%) of the 931 patients who had never smoked experienced SCD (P =.01). In multivariate analyses, current smoking was associated with a significant increase in the risk of SCD (hazard ratio, 2.47; 95% confidence interval, 1.46-4.19). Patients who had stopped smoking had no significant increase in the risk of SCD compared with patients who had never smoked (hazard ratio, 1.06; 95% confidence interval, 0.70-1.62). CONCLUSIONS: Current cigarette smoking is a powerful independent predictor of SCD risk in patients with CAD. Patients who quit smoking experienced a significant reduction in SCD risk. Thus, efforts to reduce mortality from SCD in patients with CAD should include vigorous smoking cessation strategies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
