BACKGROUND: Patient-perceived health status is receiving increased recognition as a patient-centered outcome in chronic heart failure (CHF) and coronary artery disease (CAD), but poor health status is also associated with adverse prognosis. In this systematic review, we examined current evidence on the influence of health status on prognosis in CHF and CAD. METHODS: We conducted a search of PubMed using a set of a priori-defined search terms, the Web of Science for newly cited articles, and the reference lists of eligible articles, resulting in 34 articles. RESULTS: Poor physical health status was a significant predictor for adverse health outcomes in patients with CHF and CAD. In CHF, poor physical health status seemed to be a stronger predictor of hospitalization than mortality. Little evidence was found that poor mental health status is associated with adverse prognosis in CHF and CAD. A disease-specific measure was a better predictor in CHF, but not in CAD. The majority of studies adjusted for an objective measure of disease severity. Neither the index event nor time to follow-up appeared to influence the predictive value of health status. CONCLUSIONS: Poor physical health status is associated with adverse CAD and CHF prognosis. Heterogeneity across studies makes definitive conclusions difficult as to which components of health status may be detrimental to patients' health, and how health status as a potential risk factor should be assessed, monitored, and intervened upon in clinical practice.
