BACKGROUND: New York Heart Association (NYHA) class and treadmill exercise test variables are widely used for estimating prognosis and measuring the outcomes of treatment in patients with heart failure, but they do not take patients' perceptions into account. METHODS AND RESULTS: Five hundred forty-five patients enrolled in a multicenter 24-week comparison of the effects of omapatrilat and lisinopril on functional capacity in patients with heart failure reported a visual analog scale (VAS) score of their overall health perception at week 12 of the study. A total of 27 first events, defined as death or worsening heart failure (hospitalization, emergency room visit, or study discontinuation), occurred in the subsequent 12 weeks. The mean (+/-SD) health perception scores were 0.43 +/- 0.31 and 0.68 +/- 0.20 in patients with and without events, respectively (P =.0006). The risk ratio (RR) for an event associated with a decile change in the health perception score was 0.74 (95% confidence interval [CI], 0.61-0.88; P =.001). The RR was unaltered by adjustment for demographic variables, treadmill time, and NYHA functional class. Although the week 12 NYHA functional class was predictive of events (RR = 2.1; 95% CI, 1.2-4.6; P =.04), treadmill time was not (RR = 0.87; 95% CI, 0.73-1.03; P = 0.11). CONCLUSIONS: A patient-reported measure of perceived health predicts events in patients with heart failure.
