P217 SACUBITRIL/VALSARTAN IN ADVANCED HEART FAILURE: SAFETY AND EFFECTS ON HAEMODYNAMIC PARAMETERS

Aims The angiotensin–II receptor neprilysin inhibitor (ARNI), sacubitril/valsartan has been shown to be effective in treatment of patients with heart failure (HF), but limited data is available in patients with advanced disease. This retrospective observational study assessed the effects of ARNI treatment in patients with advanced HF. Methods We reviewed medical records of all advanced HF patients evaluated at our center for unconventional therapies from September 2016 to January 2019. We studied 44 patients who started ARNI therapy and who had a hemodynamic assessment before beginning ARNI and after 6 ± 2 months. The primary endpoint was variation in pulmonary pressures and filling pressures at 6 months after starting ARNI therapy. Results Mean patient age was 51.6±7.4 years; 84% were male. At 6±2 months after starting ARNI, there was significant reduction of systolic pulmonary artery pressure (PAP) (32 mmHg, IQR 27–45 vs 25 mmHg, IQR 22.3–36.5; p Conclusions Sacubitril/valsartan is effective in reducing filling pressures and pulmonary pressures in patients with advanced HF. The absence of adverse events during follow–up suggests that sacubitril/valsartan is safe and well–tolerated in this cohort of patients.
