Abstract:
Objective To investigate the long-term effect of frailty on heart failure with reduced ejection fraction(HFrEF)in elderly patients.Methods A retrospective analysis was conducted on 245 HFrEF patients aged ≥75 years admitted to our hospital from October 2017 to October 2020 due to acute exacerbation of chronic heart failure(HF).Based on their clinical frailty scale(CFS)score,they were divided into frailty group(1-4,135 cases)and non-frailty group(5-9,110 cases).Their general clinical data,clinical medication,and prognosis were compared between the two groups,and the influencing factors for frailty and death were analyzed.Results Faster heart rate,higher NT-proBNP level,and larger proportions of male,diabetes,coronary heart disease,≥5 chronic diseases,LVEF ≤35％,anemia and increased troponin I level,while lower BMI,eGFR and score of activity of daily living scale were observed in the frailty group than the non-frailty group(P＜0.05,P＜0.01).The frail group had significantly lower utilization rates of angiotensin converting enzyme inhibitors(ACEI),angiotensin receptor blockers(ARB),angiotensin receptor enkephalin inhibitors(ARNI)β receptor blockers,and sodium-glucose cotransporter 2 inhibitors than the non-frailty group(P＜0.01).Additionally,the frailty group exhibited a higher incidence of emergency room visits/readmissions within 3 months and 2-year mortality than the non-frailty group(P＜0.05,P＜0.01).Binary logistic regression analysis revealed that ≥5 chronic diseases,LVEF ≤ 35％,BMI,and GFR were independent risk factors for frailty(OR=0.167,95％CI:0.064-0.453,P=0.000;OR=0.306,95％CI:0.160-0.586,P=0.000;OR=0.868,95％CI:0.786-0.958,P=0.005;OR=0.966,95％CI:0.943-0.991,P=0.007),while ≥5 chronic disea-ses and frailty were independent risk factors for death in HF patients(P＜0.05).Conclusion The incidence of frailty is high in elderly HF patients with HFrEF.They have poor compliance to guideline directed drug therapy(GDMT).Frailty is an independent risk factor for long-term mor-tality in the patients.
