Introduction: Heart failure is an important leading cause of mortality and morbidity despite optimal medical treatment and device therapy. Sacubitril/valsartan, a first-generation drug, was approved to use heart failure treatment recently. There are limited studies on the relationship between sacubitril/valsartan and left ventricular contraction. In our study, we aimed to evaluate the changes in left ventricular ejection fraction (LVEF) after sacubitril/valsartan treatment.
Patients and Methods: Fifty-two patients with heart failure and reduced ejection fraction (HFrEF) were enrolled in this study. The baseline demographic, clinical, and echocardiographic characteristics of 52 patients were compared using the Bayesian method.
Results: Fifty-two patients with heart failure and reduced ejection fraction (HFrEF) were included in the final analysis (66.2 ± 9.3 years, 69.2% male). Sacubitril/valsartan initial dose was low in 44.2% of patients, and intermediate in 55.8%. In the low initial dose population, the increase in absolute LVEF was 3.87 (95% HDI 1.53-6.20) and in the intermediate initial dose population, the increase in absolute LVEF was 5.89 (95% HDI 4.18-7.61). In the female population, the increase in absolute LVEF was 5.56 (95% HDI 3.49-7.63) and in the male population 4.75 (95% HDI 2.91-6.58) respectively.
Conclusion: In this study, we demonstrated that sacubitril/valsartan is associated with increased LVEF regardless of baseline clinical characteristics.
