研究目的:

1)主要研究目的:比较在重度冠脉钙化患者中,采用秋水仙碱和安慰剂预处理,对旋磨治疗后冠脉微循环障碍的预防效果,并评估秋水仙碱治疗的安全性。 2)次要研究目的:进一步阐明钙化旋磨造成远端微血管慢/无复流的机制与NETs和钙化旋磨之间的关系,为治疗旋磨术后慢/无复流并发症提供新的治疗靶点。  

Objectives of Study:

Main study objective: By comparing the effectiveness of pretreatment with colchicine and placebo in patients with severe coronary calcification, we assess not only the prevention of coronary microcirculatory disorders after rotational atherectomy treatment but also the safety of colchicine. Secondary study objective: We intend to elucidate the mechanism of slow/no-reflow in distal microvessels caused by rotational atherectomy,and the link between NETs and rotational atherectomy. Therefore, a new therapeutic target will be provided when we treat the slow/no-reflow complications after rotational atherectomy.
