ABSTRACT
The PARAGON-HF clinical trial suggested that sacubitril/valsartan may become a treatment option for particular subgroups of patients with heart failure and preserved ejection fraction (HFpEF). However, the proportion of real-world HFpEF patients who are theoretically superimposable with the PARAGON-HF population is yet unknown. The present study was performed to define the proportion of real-world PARAGON-HF-like patients and to describe their clinical characteristics and long-term prognosis in comparison with those who would not meet PARAGON-HF criteria. We systematically applied PARAGON-HF inclusion and exclusion criteria to a total of 427 HFpEF patients who have been participating in a prospective national registry between December 2010 and December 2019. In total, only 170 (39.8%) registry patients were theoretically eligible for PARAGON-HF. Patients not meeting inclusion criteria (41.0%) were less impaired with respect to exercise capacity (median 6-min walk distance 385 m (IQR 300-450) versus 323 m (IQR 240-383); p < 0.001) had lower pulmonary pressures (mean pulmonary artery pressure (mPAP) 31.2 mmHg, standard deviation (SD) ±10.2 versus 32.8 mmHg, SD ±9.7; p < 0.001) and better outcomes (log-rank p < 0.001) as compared to the PARAGON-like cohort. However, patients theoretically excluded from the trial (19.2%) were those with most advanced heart failure symptoms (median 6-min walk test 252 m (IQR 165-387); p < 0.001), highest pulmonary pressures (mPAP 38.2 mmHg, SD ±12.4; p < 0.001) and worst outcome (log-rank p = 0.037). We demonstrate here that < 40% of real-world HFpEF patients meet eligibility criteria for PARAGON-HF. We conclude that despite reasons for optimism after PARAGON-HF, a large proportion of HFpEF patients will remain without meaningful treatment options.
