Abstract | BACKGROUND: The aim of our study was to investigate the relationship between coronary artery disease (CAD), angina, and clinical outcomes in patients with heart failure and preserved ejection fraction enrolled in the irbesartan in patients with heart failure and preserved systolic function (I-Preserve) trial. METHODS AND RESULTS: The mean follow-up period for the 4128 patients enrolled in I-Preserve was 49.5 months. Patients were divided into 4 mutually exclusive groups according to history of CAD and angina: patients with no history of CAD or angina (n=2008), patients with no history of CAD but a history of angina (n=649), patients with a history of CAD but no angina (n=468), and patients with a history of CAD and angina (n=1003); patients with no known CAD or angina were the reference group. After adjustment for other prognostic variables using Cox proportional-hazard models, patients with CAD but no angina were found to be at higher risk of all-cause mortality (hazard ratio [HR], 1.58 [1.22-2.04]; P<0.01) and sudden death (HR, 2.12 [1.33-3.39]; P<0.01), compared with patients with no CAD or angina. Patients with CAD and angina were also at higher risk of all-cause mortality (HR, 1.29 [1.05-1.59]; P=0.02) and sudden death (HR, 1.83 [1.24-2.69]; P<0.01) compared with the same reference group and had the highest risk of unstable angina or myocardial infarction (HR, 5.84 [3.43-9.95]; P<0.01). CONCLUSIONS: Patients with heart failure and preserved ejection fraction and CAD are at higher risk of all-cause mortality and sudden death when compared with those without CAD.
