BACKGROUND: Prior study has demonstrated that transitioning patients in acutely decompensated heart failure with a low cardiac output directly from intravenous (i.v.) vasoactive (ie, vasodilators or inotropes) drugs to sacubitril-valsartan (S/V) can be done safely with tolerance to the 1-month follow-up. Here, we further characterize the hemodynamic impact of S/V after patients have been optimized on vasoactive therapy.
METHODS AND RESULTS: In a single-center, retrospective analysis, 25 patients with cardiac index of less than 2.2 L/min/m2 were admitted to the cardiac intensive care unit and newly initiated on angiotensin receptor-neprilysin inhibitor therapy with the guidance of invasive hemodynamic monitoring. Hemodynamic data were gathered and compared upon cardiac intensive care unit admission, after optimization with i.v. vasoactive therapy, and after S/V initiation and weaning off i.v.
THERAPY: All patients who tolerated S/V (n = 20) were weaned off vasoactive medications before transfer out of cardiac intensive care unit. Patients maintained their significant improvement in cardiac index and reduction in SVR/PVR on transition from i.v. inotropic and vasodilator therapy to oral S/V. There was an increase in pulmonary artery pulsatility index with S/V therapy compared with the i.v. vasoactive phase of care.
CONCLUSIONS: Patients in the cardiac intensive care unit can be successfully bridged from vasoactive i.v. therapy to oral S/V with sustained improvement in cardiac index garnered from vasoactive agents. We also observed improvement in the pulmonary artery pulsatility index and maintenance of left and right ventricular unloading with S/V. These encouraging findings merit further prospective study.
