【摘要】 目的:探讨行急诊PCI(pPCI)的ST段抬高型心肌梗死(STEMI)患者入院血糖水平与冠脉血运重建血流TIMI帧数(TFC)之间的关系。方法:选取2015年1月-2017年6月本院收治的行pPCI的STEMI患者188例,根据入院血糖水平将其分为高血糖组(n=65)和非高血糖组(n=123)。比较两组一般资料及冠心病危险因素;分析冠脉血管病变特征及介入治疗情况、TFC与入院血糖水平的相关关系,明确影响TFC的危险因素。结果:高血糖组中年龄、糖尿病患者比例均高于非高血糖组(P<0.05);高血糖组GRACE評分、术中无复流比例、术后TFC均高于非高血糖组,差异均有统计学意义(P<0.05);Person相关分析显示,无论是否既往有糖尿病病史,TFC与入院血糖水平均呈正相关(P<0.05);多元回归分析显示,入院血糖水平是TFC的独立预测因子(P<0.05)。结论:入院血糖水平是STEMI患者的犯罪血管PCI术后高TFC独立预测因子。

【Abstract】 Objective:To investigate the relationship between blood glucose level and TIMI frame count(TFC)of coronary revascularization in patients with ST-segment elevation myocardial infarction(STEMI)undergoing emergency PCI(pPCI).Method:A total of 188 STEMI patients for pPCI from January 2015 to June 2017 in our hospital were selected,according to admitted blood glucose levels,they were divided into hyperglycemic groups(n=65)and non-hyperglycemic groups(n=123).The general data and coronary heart disease risk factors of two groups were compared,the characteristics of coronary vascular lesions and interventional therapy,and the correlation between TFC and admitted blood glucose levels were analyzed,and the risk factors affecting TFC were analyzed.Result:The proportion of age and diabetes mellitus in hyperglycemia group were higher than those of non-hyperglycemia group(P<0.05).The GRACE score,intraoperative no-reflow ratio and postoperative TFC in hyperglycemia group were higher than those of non-hyperglycemia group(P<0.05).Person analysis shows that whether or not there is a history of diabetes,TFC was positively correlated with admitted blood glucose level(P<0.05).Multivariate regression analysis showed that admission blood glucose level was an independent predictor of TFC(P<0.05).Conclusion:Admission blood glucose is an independent predictor of high TFC in STEMI patients after PCI.

糖尿病(DM)和冠状动脉性心脏病(CAD)患病率密切相关[1-2],两者均为多发慢性疾病。DM与CAD既可单发,也可合并发生,可能导致患者的生活质量预期寿命明显下降。随着生活质量提升,饮食结构变化以及老龄化等问题,两者发病均有上升趋势。虽然DM与CAD发病机制不同,但彼此联系密切[3]。DM可能提示CAD患者不良预后。与非DM患者相比,DM患者发生急性心肌梗死(AMI)后的预后较差[4]。既往研究显示,高血糖水平是AMI患者死亡率和院内并发症增加的独立危险因素[5]。然而高血糖不良预后影响的潜在机制尚不清楚。有研究显示,高血糖会损害微血管循环,并可能导致冠脉无复流现象[6]。如何评价微循环血流情况时是心肌灌注的重点。心肌梗死溶栓试验血流(TIMI)帧数(TFC)最初用于AMI患者冠脉再灌注的定量分级[7-8]。研究显示,TFC与AMI患者介入治疗后ST段回落密切相关,能很好地反应心肌缺血情况[9]。随访结果发现,TFC能预测梗死区域心肌局部收缩功能恢复情况,可作为评估AMI患者PCI术后疗效的预测指标[10]。因此,本文旨在探讨行急诊PCI(pPCI)的ST段抬高型心梗(STEMI)患者入院血糖水平与冠脉血运重建后TFC之间的关系。现报道如下。
然而,这是一项单中心研究,样本量较少,存在患者选择偏倚可能。且本研究使用TFC来评估冠状动脉血流,没有通过造影超声心动图等其他手段进一步确认研究结果。
综上所述,无论是否既往有糖尿病病史,入院血糖水平均与TFC呈正相关,是STEMI患者的犯罪血管PCI术后高TFC独立预测因子。
