Abstract

Abstract

Objective To investigate the status quo of drug therapy and the factors affecting the standardized drug therapy in patients with heart failure with chronic ejection fraction reduction （HFrEF） in Yunnan province. Methods This is a single-center, prospective, and observational study. A total of 110 patients who were hospitalized in the Department of Cardiology in the First Affiliated Hospital of Kunming Medical University during July 2019 to September 2020 were enrolled.The utilization rate and dose of ACEI/ARB/ARNI, β-blocker and MRA were collected during hospitalization, 3 and 6 months after discharge. According to the drug dose at discharge, patients were divided into 100% target dose group, 50% ～ 99% target dose group and < 50% target dose group, and the factors affecting the standardized drug treatment were analyzed. Results The average age of 110 HFrEF patients was （57.9±14.1） years old, among which 65 （58.6%） were males. The utilization rates of ACEI/ARB/ARNI, β-blocker and MRA at discharge （73.6% , 82.1% , 89.6% , respectively） were higher than that at 3 months （69.8% , 79.2% , 84.4% , respectively） and 6 months （69.0% , 78.6% , 78.6% , respectively） after discharge. Both of 100% target dose of ACEI/ARB/ARNI and β-blocker were lower at the time of discharge, 3 and 6 months after discharge, among which the 100% target dose rate of β-blocker was the lowest. ACEI/ARB/ARNI and β-blocker usage at 100% target dose was lower at discharge, 3 months after discharge, and 6 months after discharge, with rates of 12.8% and 1.1%, 14.9% and 0%, and 15.5% and 1.5% respectively. Among them, the rate of reaching the target dose was the lowest for β-blockers. When comparing the three groups of 100% target dose, 50-99% target dose, and < 50% target dose, patients in the ACEI/ARB/ARNI 50-99% target dose group had higher body mass index （25.5±3.4 vs. 23.2±4.1, P = 0.038） and systolic blood pressure （131.1±21.6 vs 109.7±14.9, P < 0.001） than those in the < 50% target dose group. There were no significant differences in NYHA functional classification, BNP, and serum creatinine among the three groups （P > 0.05）. The age of patients in the β-blocker 50-99% target dose group was significantly lower than that in the < 50% target dose group （46.9±10.0 vs. 64.4±13.2, P = 0.005）, and there were no significant differences in NYHA functional classification, heart rate, and systolic blood pressure among the three groups （P > 0.05）. During hospitalization, the main reasons for the underuse or suboptimal dose of heart failure medications were lack of prescription by doctors, drug intolerance, and contraindications. After discharge, apart from contraindications, the main reasons for non-compliance with medication guidelines were patient self-discontinuation and lack of prescription by doctors. Conclusions In HFrEF patients in some areas of Yunnan Province, the utilization rate and dosage of ACEI/ARB/ARNI and β-blockers were low. With the extension of discharge time, the utilization rate of drugs continued to decline, and the dosage did not increase significantly. Drug contraindications or intolerances in patients, self-withdrawal after discharge and non-prescription by doctors are the important reasons for non-standardized drug use.
