Impact of chronic obstructive pulmonary disease in patients with heart failure with preserved ejection fraction: Insights from paragon-hf

Research output: Contribution to journalArticlepeer-review

Abstract

BACKGROUND: Little is known about the impact of chronic obstructive pulmonary disease (COPD) in patients with heart failure with preserved ejection fraction (HFpEF). METHODS AND RESULTS: We examined outcomes in patients with heart failure with preserved ejection fraction, according to COPD status, in the PARAGON-HF (Prospective Comparison of Angiotensin Receptor Neprilysin Inhibitor With Angiotensin Receptor Blocker Global Outcomes in Heart Failure With Preserved Ejection Fraction) trial. The primary outcome was a composite of first and recurrent hospitalizations for heart failure and cardiovascular death. Of 4791 patients, 670 (14%) had COPD. Patients with COPD were more likely to be men (58% versus 47%; P<0.001) and had worse New York Heart Association functional class (class III/IV 24% versus 19%), worse Kansas City Cardiomyopathy Questionnaire Clinical Summary Scores (69 versus 76; P<0.001) and more frequent history of heart failure hospitalization (54% versus 47%; P<0.001). The decrement in Kansas City Cardiomyopathy Questionnaire Clinical Summary Scores with COPD was greater than for other common co-morbidities. Patients with COPD had echocardiographic right ventricular enlargement, higher serum creatinine (100 μmol/L versus 96 μmol/L) and neutrophil-to-lymphocyte ratio (2.7 versus 2.5), than those without COPD. After multivariable adjustment, COPD was associated with worse outcomes: adjusted rate ratio for the primary outcome 1.51 (95% CI, 1.25–1.83), total heart failure hospitalization 1.54 (95% CI, 1.24–1.90), cardiovascular death (adjusted hazard ratio [HR], 1.42; 95% CI, 1.10–1.82), and all-cause death (adjusted HR, 1.52; 95% CI, 1.25–1.84). COPD was associated with worse outcomes than other comorbidities and Kansas City Cardiomyopathy Questionnaire Clinical Summary Scores declined more in patients with COPD than in those without. CONCLUSIONS: Approximately 1 in 7 patients with heart failure with preserved ejection fraction had concomitant COPD, which was associated with greater functional limitation and a higher risk of heart failure hospitalization and death.
