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.
ABSTRACT
To perform a systematic review and network meta-analysis evaluating the efficacy and safety of low-molecular-weight heparins (LMWHs), vitamin K antagonists (VKAs), and direct-acting oral anticoagulants (DOACs) for the treatment of cancer-associated thrombosis (CAT). We searched MEDLINE, Cochrane Central Register of Controlled Trials, and conference abstracts through March 2018. Randomized controlled trials (RCTs) enrolling adults with CAT comparing 2 or more full-dose anticoagulants (LMWH, VKA, and DOAC) and evaluating recurrent venous thromboembolism (VTE), major bleeding, and/or all-cause mortality were included. Reviewers identified studies, extracted data, and assessed the quality of the evidence in duplicate. A frequentist network meta-analysis, which uses direct and indirect evidence to simultaneously compare multiple interventions, was performed using a random-effects approach. Results are reported as pooled relative risks (RRs) with 95% confidence intervals (CIs). We included 13 RCTs (n = 6292): 7 compared LMWHs with VKAs, 4 compared DOACs with VKAs, and 2 compared DOACs with LMWHs. The risk of recurrent VTE was significantly reduced by 28% and 54% with a DOAC compared to an LMWH and a VKA, respectively. Low-molecular-weight heparins significantly reduced the risk of recurrent VTE by 36% versus VKAs. The risk of major bleeding was 14% higher with DOACs compared to LMWHs and 15% and 25% lower with DOACs and LMWHs versus VKAs, although 95% CIs included unity for each. The risk of all-cause mortality appeared similar for all 3 comparisons (RR = 1.0 for each comparison). Direct-acting oral anticoagulants appeared superior in reducing recurrent VTE in patients with CAT compared to LMWH and VKAs, but an increased risk of major bleeding versus LMWH cannot be ruled out.
