Abbreviations: BDI-II: Beck Depression Inventory-II; SDS: summed difference score; CI: confidence interval; CAD: coronary artery disease. †The β coefficient expresses the difference in SDS score points with a 1-point increase in BDI-II total score. Each model was constructed with SSS as dependent variable adjusting for the rest score (SRS). SE: standard error. ‡Sex, employment, race, marital status and cigarette smoking. §Gensini angiographic CAD severity score, left ventricular ejection fraction, hypertension, diabetes, BMI, previous revascularization procedures, use of statins, beta-blockers, and anti-depressants.
