Abstract:Objective To explore the effect of sacubitril and valsartan on ventricular remodeling and prognosis in patients with heart failure with reduced ejection fraction with or without type 2 diabetes mellitus (T2DM).Methods The 101 patients with heart failure admitted to our hospital were divided into two groups according to the presence of T2DM, where 57 patients with heart failure without T2DM were enrolled as the control group and 44 patients with heart failure with T2DM were enrolled as the study group. Both groups of patients took the oral tablets of sacubitril and valsartan for 12 months, and the therapeutic efficacy was evaluated at the end of the treatment. The patients were followed up for another 12 months after the treatment. The therapeutic efficacy, and the ventricular remodeling and the myocardial injury before and after the treatment were compared between the two groups. Besides, the safety of the drug and the prognosis of the two groups of patients were recorded.Results There was no significant difference in the overall effective rate between the two groups (P > 0.05). The differences in left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), and left ventricular end-systolic diameter (LVESD) before and after the treatment in the study group were lower than those in the control group (P < 0.05). The differences in N-terminal pro-B-type natriuretic peptide (NT-proBNP) and cardiac troponin Ⅰ (cTnⅠ) before and after the treatment in the study group were lower than those in the control group (P < 0.05). There was no significant difference in the overall incidence of adverse reactions or cardiac adverse events between the two groups (P > 0.05).Conclusions The presence of T2DM does not affect the efficacy and safety of sacubitril and valsartan in the treatment of patients with heart failure with reduced ejection fraction, and the short-term prognosis is also comparable between patients with and without T2DM. However, sacubitril and valsartan exhibits more pronounced effects on improving the ventricular remodeling and the myocardial injury in those without T2DM.
