Abstract
Background: Initiation of sacubitril-valsartan and mineralocorticoid receptor antagonists (MRA) during hospitalization for acute decompensated heart failure (ADHF) may be an ideal time to optimize guideline-directed medical therapy. However, there is limited research assessing the safety of combining these agents in the hospital. Methods: This was a multi-center, retrospective, propensity-score matched cohort study performed at 7 acute-care hospitals within a large health care system. All adult patients admitted with ADHF between January 1, 2019 to December 31, 2021 who received sacubitril-valsartan with MRA (MRA group) or without MRA (non-MRA group) and had a left ventricular ejection fraction (LVEF) < 40% were included in the study. Results: 220 patients were screened during the study time frame with 179 meeting inclusion criteria. Following propensity-score matching, 50 patients in the MRA group were matched to 50 patients in the non-MRA group. The overall incidence of adverse drug reactions (ADRs) was 24% in the non-MRA group compared to 20% in the MRA group (P = .629). There was a significantly greater incidence of hyperkalemia in the MRA group (0% vs 10%; P = .022). None of the patients in the non-MRA group were readmitted within 30 days due to an ADR compared to 6% in the MRA group (P = .079). Conclusion: The addition of spironolactone to sacubitril-valsartan in the hospital setting following stabilization of ADHF did not lead to a significantly greater incidence of overall ADRs, but patients were more likely to develop hyperkalemia and there was a numerically higher incidence of 30-day readmissions due to ADRs.
