研究目的:

本研究旨在探讨CABG术前早期应用PCSK9抑制剂对EAT和冠脉粥样硬化斑块的干预作用,并可能通过调节EAT的炎症浸润、延缓冠状动脉粥样硬化的进展而改善桥血管通畅率,最终改善患者预后。  

Objectives of Study:

This study aimed to investigate the interventional effects of early preoperative application of PCSK9 inhibitors on Epicardial Adipose Tissue and coronary atherosclerotic plaques in patients undergoing Coronary Artery Bypass Grafting . It is hypothesized that the intervention may improve graft patency rates by modulating inflammatory infiltration in EAT and delaying the progression of coronary atherosclerosis, ultimately leading to improved patient outcomes.

药物成份或治疗方案详述:

入选120例拟行CABG术患者,冠脉CT检查测定EAT体积,CABG术前7天(+/-3天)按照1:1比例随机分至强化组和常规组,强化组给予强化降脂,即PCSK9抑制剂托莱西单抗150mg QOW+瑞舒伐他汀10mg QN依折麦布10mg QD;常规组接受常规降脂,即瑞舒伐他汀10mg QN依折麦布10mg QD,术中采集EAT,检测其中炎症因子表达,术后维持以上调脂方案,进行为期26周随访。 

Description for medicine or protocol of treatment in detail:

120 patients eligible for CABG surgery will be enrolled, and the EAT volume is measured by coronary CT examination. Seven days before CABG surgery (+/-3 days), the subjects are randomly divided into an enhanced group and a conventional group in a 1:1 ratio. The enhanced group is given enhanced lipid-lowering therapy, which included PCSK9 inhibitor trastuzumab 150mg QOW+rosuvastatin 10mg QN and ezetimibe 10mg QD; The routine group receives routine lipid-lowering, namely rosuvastatin 10mg QN and ezetimibe 10mg QD. EAT is collected during surgery to detect the expression of inflammatory factors. The above lipid-lowering regimens are maintained after surgery during a 26 week follow-up.
