研究疾病:

瓣膜反流术后左心室重构  

Target disease:

Left ventricular remodeling after valvular regurgitant surgery

研究疾病代码:

Target disease code:

研究类型:

干预性研究

Study type:

Interventional study

研究所处阶段:

上市后药物 

Study phase:

4

研究设计:

随机平行对照 

Study design:

Parallel 

研究目的:

1. 通过比较术后残余左心室重构出现完全逆转的时间点、发生率,探究血管紧张素受体脑啡肽酶抑制剂(angiotensin receptor-neprilysin inhibitor, ARNI)治疗的有效性是否优于血管紧张素受体阻滞剂(angiotensin receptor blocker, ARB); 2. 在左心室重构完全逆转的患者中,通过比较停药与继续用药,探究停药后左心室重构是否复发,并进一步比较复发率在ARNI与ARB组有无区别。  

Objectives of Study:

1. Explore the efficacy of ARNI in left ventricular reverse remodeling over ARB in patients with residual LV remodeling after AR and/or MR surgery. 2. Explore the probability of relapse in patients with recovered LV remodeling after treatment withdrawal.
