Popis: Background: Limited evidence regarding the use of guideline directed medical therapy (GDMT) in patients with heart failure with reduced ejection fraction (HFrEF) undergoing coronary artery bypass grafting (CABG) is available. Objective: The purpose of this study was to characterize prescription of HFrEF GDMT use before and after CABG. Methods: A retrospective analysis of adult patients with an ejection fraction ≤40% undergoing CABG was performed. The primary objective was to evaluate patients receiving HFrEF GDMT, defined as a heart failure beta-blocker (HFBB) and a renin-angiotensin inhibitor preoperatively and postoperatively. Secondary outcomes included dosing, percent of patients on each individual therapy, mineralocorticoid receptor antagonist (MRA) use, and the combination thereof. The follow up period was 1 year. Results: Thirty-eight patients met criteria for inclusion. Prior to CABG, 52.6% of patients were receiving HFrEF GDMT. The prescribing rate of HFrEF GDMT was not significantly higher at any point within 1 year postoperatively ( P = .299). The rate of renin-angiotensin inhibitors, HFBB, and aldosterone antagonists use significantly increased from 13.2% preoperatively to 36.8% at 1 year after CABG ( P = .022). Doses of individual therapies were not significantly different across all time points preoperatively and postoperatively. Conclusion: HFrEF GDMT use and doses of individual therapies after CABG were not maximized. Collaborative efforts between cardiac surgeons, heart failure cardiologists, and pharmacists could be used to optimize HFrEF GDMT use and dose titration.
