Abstract
OBJECTIVE: To assess the prevalence of guideline-directed medical therapy (GDMT) and identify reasons for nonprescription and dose optimization in heart failure patients with reduced ejection fraction (HFrEF) in a tertiary care hospital in southern India.
METHODS: A cross-sectional study was conducted in a tertiary care hospital involving HFrEF patients. Patients with heart failure were categorized based on GDMT prescriptions. Reasons for nonprescription and suboptimal dosing were identified.
RESULTS: The study included 102 HFrEF patients with a mean age of 54 ± 11.7 years, predominantly male (89%). Only 10.8% of patients received GDMT at optimal doses. Although 62% were on triple therapy, many had one or more medications at suboptimal doses. Additionally, 26% of patients were not prescribed all recommended drug classes. Notably, the majority of patients with renal impairment fail to receive triple therapy. Barriers identified included hemodynamic issues and renal dysfunction.
CONCLUSION: GDMT adherence in HFrEF patients is significantly lower than expected, with only 10.8% receiving therapy at recommended doses. Key issues include suboptimal dosing and incomplete prescription of drug classes, influenced by patient-specific factors and systemic barriers.
