OBJECTIVE: In this post hoc analysis of the PARAGON-HF (Prospective Comparison of ARNI with ARB Global Outcomes in HFpEF) trial, we evaluated clinical outcomes and responses to sacubitril/valsartan by duration of heart failure (HF) with left ventricular ejection fraction ≥ 45% at initial diagnosis.
METHODS AND RESULTS: The primary outcome was a composite of total hospitalizations due to HF and cardiovascular deaths, analyzed by using a semiparametric proportional rates method, stratified by geographic region. Among 4784 (99.7%) randomized participants in the PARAGON-HF trial for whom baseline HF duration was captured, 1359 (28%) had durations of HF of < 6 months, 1295 (27%) of 6 months-2 years, and 2130 (45%) of > 2 years. Longer HF duration was associated with higher comorbidity burdens, worse health status and lower rates of prior hospitalization due to HF. Over a median follow-up of 35 months, longer HF duration was associated with a higher risk of first and recurrent primary events (per 100 patient-years): < 6 months, 12.0 (95% CI, 10.4-14.0); 6 months-2 years, 12.2 (10.6-14.2); > 2 years, 15.8 (14.2-17.5). Relative treatment effects of sacubitril/valsartan vs valsartan were consistent, irrespective of baseline HF duration on the primary endpoint (Pinteraction = 0.112). Clinically meaningful (≥ 5 point) improvements in Kansas City Cardiomyopathy Questionnaire-Clinical Summary Scores were also similarly observed, irrespective of HF duration; (Pinteraction = 0.112). Adverse events were similar between treatment arms across HF duration categories.
CONCLUSIONS: In PARAGON-HF, longer HF duration was independently predictive of adverse HF outcomes. Treatment effects of sacubitril/valsartan were consistent, irrespective of baseline HF duration, suggesting that even ambulatory patients with longstanding HFpEF and predominantly mild symptoms stand to benefit from treatment optimization.
