目的:探讨心肌桥与冠状动脉内支架植入术后再狭窄的关系。方法:选择从2015年1月到2015年12月在我院心内科导管室接受冠脉造影明确冠心病诊断并植入药物洗脱支架的患者共183例,其中合并心肌桥组16例,不合并心肌桥组167例。术后两组患者均规律服用相关药物,并于术后6-8月返院复查冠脉造影。结果:合并心肌桥组患者支架内再狭窄发生率为25%(4例),而不合并心肌桥组支架内再狭窄发生率为6.6%(11例),两组比较有统计学差异(P<0.05);合并心肌桥组患者主要不良心脏事件发生率明显高于无心肌桥组患者(P<0.05)。结论:合并心肌桥的冠心病患者支架内再狭窄的发生率及主要心血管不良事件发生率均高于不合并心肌桥的患者;心肌桥可能增加支架内再狭窄的发生率。
Objective: To investigate the relationship between myocardial bridge and restenosis after coronary stent implantation. Methods: From January 2015 to December 2015 in our hospital cardiology catheterization room confirmed by coronary angiography diagnosis of coronary heart disease and implantation of drug-eluting stents in patients with a total of 183 cases, of which 16 cases were combined myocardial bridge, not 167 patients with myocardial bridge. After the two groups of patients regularly take the relevant drugs, and returned to the hospital after 6-8 months coronary angiography. Results: The incidence of in-stent restenosis was 25% (4 cases) in patients with myocardial bridge and 6.6% (11 cases) in non-myocardial-bridge group. There was significant difference between the two groups (P <0.05). The incidence of major adverse cardiac events in patients with myocardial bridge was significantly higher than those in patients without myocardial bridge (P <0.05). Conclusion: The incidence of in-stent restenosis and the incidence of major adverse cardiac events in patients with coronary heart disease complicated with myocardial bridge are higher than those without myocardial bridge. The myocardial bridge may increase the incidence of in-stent restenosis.
