Heart failure with preserved ejection fraction: comparison of patients with and without angina pectoris (from the Duke Databank for Cardiovascular Disease).
OBJECTIVES: This study investigated the characteristics and outcomes of patients with heart failure with preserved ejection fraction (HFpEF) and angina pectoris (AP). BACKGROUND: AP is a predictor of adverse events in patients with heart failure with reduced EF. The implications of AP in HFpEF are unknown. METHODS: We analyzed HFpEF patients (EF ≥50%) who underwent coronary angiography at Duke University Medical Center from 2000 through 2010 with and without AP in the previous 6 weeks. Time to first event was examined using Kaplan-Meier methods for the primary endpoint of death/myocardial infarction (MI)/revascularization/stroke (i.e., major adverse cardiac events [MACE]) and secondary endpoints of death/MI/revascularization, death/MI/stroke, death/MI, death, and cardiovascular death/cardiovascular hospitalization. RESULTS: In the Duke Databank, 3,517 patients met criteria for inclusion and 1,402 (40%) had AP. Those with AP were older with more comorbidities and prior revascularization compared with non-AP patients. AP patients more often received beta-blockers, angiotensin-converting enzyme inhibitors, nitrates, and statins (all p < 0.05). In unadjusted analysis, AP patients had increased MACE and death/MI/revascularization (both p < 0.001), lower rates of death and death/MI (both p < 0.05), and similar rates of death/MI/stroke and cardiovascular death/cardiovascular hospitalization (both p > 0.1). After multivariable adjustment, those with AP remained at increased risk for MACE (hazard ratio [HR]: 1.30, 95% confidence interval [CI]: 1.17 to 1.45) and death/MI/revascularization (HR: 1.29, 95% CI: 1.15 to 1.43), but they were at similar risk for other endpoints (p > 0.06). CONCLUSIONS: AP in HFpEF patients with a history of coronary artery disease is common despite medical therapy and is independently associated with increased MACE due to revascularization with similar risk of death, MI, and hospitalization.
