The Effect of Sacubitril/Valsartan on Cardiovascular Events in Dialysis Patients and Efficacy Prediction of Baseline LVEF Value

Patients with end stage renal disease (ESRD), especially after having maintenance dialysis are among the highest risk of heart failure (HF), which is the most important cause that affects survival rate and quality of life. Sacubitril/Valsartan is recommended as a first-line option for treating symptomatic chronic heart failure, especially HF with reduced ejection fraction (HFrEF). Sacubitril/Valsartan was reported the different effectiveness in HFrEF and HF with preserved ejection fraction (HFpEF), and the clinical trials' results are controversial in HFpEF patients. So far, there have been seven clinical trials (or subgroups of trials) that used sacubitril/valsartan in heart failure patients with chronic kidney disease, only one retrospective study to evaluate the improvement of cardiovascular biomarkers and LVEF in hemodialysis patients who have HFrEF. In addition, there is no article predicting the outcomes of Sacubitril/Valsartan, the inclusion criteria of LVEF value are not consistent. Investigators will perform a prospective, cohort study to evaluate the efficacy and safety of Sacubitril/Valsartan on Cardiovascular Events Outcome in Maintenance hemodialysis and peritoneal dialysis patients with Heart Failure, and use secondary analysis to find out the range of baseline LVEF Value to predict the therapeutic effects.

The trial will examine the effect of Sacubitril/Valsartan on cardiovascular events in HF patients receiving maintenance hemodialysis or peritoneal dialysis. Subjects will be divided into two groups (1:1 matching will be achieved after a screening of propensity score) to receive one of two interventions in addition to standard HF management: Sacubitril/Valsartan group or RAAS inhibitor group. All subjects can have a beta-blocker, CCB, and/or alpha-blockers to control BP. Dialysis treatment: patients normally complete hemodialysis or peritoneal dialysis, need to ensure adequate dialysis requirements, no obvious overload, patients achieve dry weight after dialysis. Participants will be treated and follow-up for at least 18 months.
