Association of SF-36 with coronary artery disease risk factors and mortality: a PreCIS study.

This study examined the relationships among health-related quality of life and risk factors of coronary artery disease (CAD) and all-cause mortality in high-risk cardiac patients seen in a cardiology prevention clinic. At baseline, 1785 patients (age, 53.4+/-13.4 years; 58.8% men) had a medical history, physical examination, and laboratory tests. They completed the Medical Outcomes Study Short Form-36-Item Health Survey (SF-36). Analyses were conducted on associations of 2 SF-36 domain scores (overall physical health [OPH] and overall mental health [OMH]) with CAD biomarkers and all-cause mortality. Lower OPH scores were associated with CAD risk factors including smoking; history of hypertension, diabetes, and peripheral artery disease; the metabolic syndrome; and other novel CAD biomarkers. Lower OMH scores showed similar but weaker associations with CAD risk factors. OPH significantly predicted 5-year mortality in multivariable survival analysis. SF-36, especially OPH, was associated with many risk factors of CAD and significantly predicted mortality. (c) 2009 Wiley Periodicals, Inc.
