Treatment of Moderate Ischemic Mitral Regurgitation in Patients With Coronary Artery Disease

Treatment of Moderate Ischemic Mitral Regurgitation in Patients With Coronary Artery Disease

This study aims to evaluate the effect of angiotensin receptor/neprilysin inhibitors (ARNI) on improving ischemic mitral regurgitation (IMR) in patients with coronary artery disease undergoing isolated coronary artery bypass grafting (CABG) through a randomized controlled clincial trial.

Inclusion Criteria:

1. Fully informed and voluntarily signed informed consent;
2. Received CABG and moderate IMR was diagnosed on two consecutive preoperative transthoracic echocardiography (according to 2021 ESC/EACTS Guidance Standards )

Exclusion Criteria:

1.Symptomatic hypotension and/or a SBP < 100 mmHg at screening; 2.Estimated GFR < 30 mL/min/1.73m2; 3.Serum potassium > 5 mmol/L at screening; 4.History of angioedema or unacceptable side effects while receiving ACE inhibitors or ARBs; 5.Patients receiving mitral valve intervention at the same time, or have participated in other clinical trials, or are unwilling to participate in this study.
