摘要:

背景:采用裸金属支架置入治疗心肌梗死可在一定程度上改善心肌功能,但容易出现血栓等情况。

目的:分析肝素缓释支架对急性心肌梗死后患者血管再生及心肌功能改善的影响。

方法:纳入急性心肌梗死患者87例,其中男47例,女40例,年龄55-81岁,分两组治疗,观察组(n=45)经皮冠状动脉置入肝素缓释支架,对照组(n=42)经皮冠状动脉置入裸金属支架。随访12个月,观察两组血管再生、心肌功能改善及心脏不良事件发生情况。

结果与结论:观察组新生血管密度A值、心肌存活面积A值、左心室射血分数均高于对照组(P < 0.05);随访3个月时,观察组有1例出现再次血运重建,1例出现急性复发心肌梗死;对照组有1例患者出现再次血运重建,1例出现急性复发心肌梗死,1例出现心脏性死亡,两组心脏不良反应情况比较差异无显著性意义。表明经皮冠状动脉置入肝素缓释支架治疗急性心肌梗死可有效促进血管再生,改善心肌功能,并具有良好的生物相容性。

Abstract:

BACKGROUND: Bare-metal stent for treatment of myocardial infarction may improve cardiac function to some extent, but it is prone to induce thrombus.

OBJECTIVE: To explore the effect of heparin slow-release stent on angiogenesis and cardiac function of patients with acute myocardial infarction.

METHODS: A total of 87 patients with acute myocardial infarction were enrolled, including 47 males and 40 females, aged 55-81 years. These patients were divided into observation group (n=45) with percutaneous coronary intervention with heparin slow-release stent and control group (n=42) with percutaneous coronary intervention with bare metal stent. The follow-up period was 12 months, and angiogenesis, cardiac function improvement and adverse cardiac events in the two groups were observed and compared.

RESULTS AND CONCLUSION: The new blood vessel density, myocardial survival area and left ventricular ejection fraction were all higher in the observation group than the control group (P < 0.05). At 3 months after intervention, there was one case of revascularization and one case of recurrent acute myocardial infarction in the observation group; in the control group, there was case of revascularization, one case of recurrent acute myocardial infarction and one case of sudden cardiac death, and there was no difference between the two groups. These findings indicate that that percutaneous coronary intervention with heparin slow-release stent has good biocompatibility and can effectively promote the regeneration of blood vessels and improve cardiac function of patients with acute myocardial infarction.
