Abstract:Objective To investigate the therapeutic effect of sacubitril and valsartan combined with carvedilol in elderly patients with chronic heart failure arising from different etiologies.Methods A total of 89 patients with chronic heart failure admitted to Changzhou Fourth People's Hospital from March 2019 to February 2021 were selected and divided into coronary heart disease group (45 cases), hypertensive heart disease group (16 cases) and dilated cardiomyopathy group (28 cases) according to the etiologies. All patients were treated with sacubitril and valsartan combined with carvedilol for 3 months. The cardiac function parameters, clinical efficacy, serological indicators and adverse reactions during the treatment were compared among the three groups of patients.Results There was no difference in left ventricular end diastolic diameter (LVEDD), left ventricular end systolic diameter (LVESD), left ventricular ejection fraction (LVEF) and cardiac index among the three groups before the treatment (P > 0.05). The LVEDD and LVESD of the three groups were all lower after the treatment than those before the treatment (P < 0.05), while the LVEF and cardiac index were higher after the treatment than those before the treatment (P < 0.05). After the treatment, LVEDD, LVESD, LVEF and cardiac index were not different among the three groups (P > 0.05). There was also no difference in the clinical efficacy, the overall effective rate, or the incidence of adverse reactions among the three groups of patients (P > 0.05).Conclusions The sacubitril and valsartan combined with carvedilol can be applied in the treatment of elderly patients with chronic heart failure, with parallel clinical efficacy and adverse reactions among the patients with chronic heart failure due to different etiologies.
