【摘要】 目的:探討行急診PCI(pPCI)的ST段抬高型心肌梗死(STEMI)患者入院血糖水平與冠脈血運(yùn)重建血流TIMI幀數(shù)(TFC)之間的關(guān)系。方法:選取2015年1月-2017年6月本院收治的行pPCI的STEMI患者188例,根據(jù)入院血糖水平將其分為高血糖組(n=65)和非高血糖組(n=123)。比較兩組一般資料及冠心病危險(xiǎn)因素;分析冠脈血管病變特征及介入治療情況、TFC與入院血糖水平的相關(guān)關(guān)系,明確影響TFC的危險(xiǎn)因素。結(jié)果:高血糖組中年齡、糖尿病患者比例均高于非高血糖組(P<0.05);高血糖組GRACE評(píng)分、術(shù)中無(wú)復(fù)流比例、術(shù)后TFC均高于非高血糖組,差異均有統(tǒng)計(jì)學(xué)意義(P<0.05);Person相關(guān)分析顯示,無(wú)論是否既往有糖尿病病史,TFC與入院血糖水平均呈正相關(guān)(P<0.05);多元回歸分析顯示,入院血糖水平是TFC的獨(dú)立預(yù)測(cè)因子(P<0.05)。結(jié)論:入院血糖水平是STEMI患者的犯罪血管PCI術(shù)后高TFC獨(dú)立預(yù)測(cè)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?。―M)和冠狀動(dòng)脈性心臟?。–AD)患病率密切相關(guān)[1-2],兩者均為多發(fā)慢性疾病。DM與CAD既可單發(fā),也可合并發(fā)生,可能導(dǎo)致患者的生活質(zhì)量預(yù)期壽命明顯下降。隨著生活質(zhì)量提升,飲食結(jié)構(gòu)變化以及老齡化等問(wèn)題,兩者發(fā)病均有上升趨勢(shì)。雖然DM與CAD發(fā)病機(jī)制不同,但彼此聯(lián)系密切[3]。DM可能提示CAD患者不良預(yù)后。與非DM患者相比,DM患者發(fā)生急性心肌梗死(AMI)后的預(yù)后較差[4]。既往研究顯示,高血糖水平是AMI患者死亡率和院內(nèi)并發(fā)癥增加的獨(dú)立危險(xiǎn)因素[5]。然而高血糖不良預(yù)后影響的潛在機(jī)制尚不清楚。有研究顯示,高血糖會(huì)損害微血管循環(huán),并可能導(dǎo)致冠脈無(wú)復(fù)流現(xiàn)象[6]。如何評(píng)價(jià)微循環(huán)血流情況時(shí)是心肌灌注的重點(diǎn)。心肌梗死溶栓試驗(yàn)血流(TIMI)幀數(shù)(TFC)最初用于AMI患者冠脈再灌注的定量分級(jí)[7-8]。研究顯示,TFC與AMI患者介入治療后ST段回落密切相關(guān),能很好地反應(yīng)心肌缺血情況[9]。隨訪結(jié)果發(fā)現(xiàn),TFC能預(yù)測(cè)梗死區(qū)域心肌局部收縮功能恢復(fù)情況,可作為評(píng)估AMI患者PCI術(shù)后療效的預(yù)測(cè)指標(biāo)[10]。因此,本文旨在探討行急診PCI(pPCI)的ST段抬高型心梗(STEMI)患者入院血糖水平與冠脈血運(yùn)重建后TFC之間的關(guān)系?,F(xiàn)報(bào)道如下。
然而,這是一項(xiàng)單中心研究,樣本量較少,存在患者選擇偏倚可能。且本研究使用TFC來(lái)評(píng)估冠狀動(dòng)脈血流,沒(méi)有通過(guò)造影超聲心動(dòng)圖等其他手段進(jìn)一步確認(rèn)研究結(jié)果。
綜上所述,無(wú)論是否既往有糖尿病病史,入院血糖水平均與TFC呈正相關(guān),是STEMI患者的犯罪血管PCI術(shù)后高TFC獨(dú)立預(yù)測(cè)因子。
