Heart Failure With Preserved Ejection Fraction: Comparison of Patients With and Without Angina Pectoris (From the Duke Databank for Cardiovascular Disease)

Objectives tudy investigated the characteristics and outcomes of patients with heart failure with preserved ejection fraction (HFpEF) and angina pectoris (AP). ound a predictor of adverse events in patients with heart failure with reduced EF. The implications of AP in HFpEF are unknown. s lyzed 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. s 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). sions 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.
