摘要(Abstract):
目的 评估冠状动脉斑块旋磨术治疗冠状动脉弥漫钙化病变的长期安全性及有效性。方法 连续纳入2015年1月至2020年12月于北京大学人民医院因重度钙化病变行冠状动脉斑块旋磨术并符合研究入选标准的188例患者。根据旋磨靶病变长度分为弥漫病变(≥25 mm)旋磨组(98例)和标签内旋磨组(90例),比较两组患者旋磨术中并发症(C型以上冠状动脉夹层、慢血流/无复流、冠状动脉破裂、旋磨导丝断裂、旋磨头嵌顿)、住院期间主要不良心血管事件(全因死亡、经皮冠状动脉介入治疗相关心肌梗死、靶血管再次血运重建、急性/亚急性支架内血栓形成)及随访期间主要不良心血管事件(全因死亡、非致死性心肌梗死、靶血管再次血运重建、支架内血栓形成)的发生率。结果 两组患者临床基线资料匹配,差异无统计学意义(均P>0.05)。弥漫病变旋磨组旋磨术中并发症发生率高于标签内旋磨组(7.1%比3.3%,P=0.247),尤其是慢血流/无复流的发生率(5.1%比1.1%,P=0.121),但差异均无统计学意义。两组患者住院期间主要不良心血管事件发生率的差异无统计学意义(7.8%比11.2%,P=0.923),平均随访33.4个月,两组患者主要不良心血管事件发生率的差异无统计学意义(14.4%比15.3%,P=0.489)。结论 与标签内旋磨相比,冠状动脉斑块旋磨术治疗弥漫钙化病变安全有效,不增加住院期间和远期心血管事件风险。
