目的比较不同分层标准SYNTAX积分对经皮冠状动脉介入治疗(PCI)复杂冠心病患者临床预后的预测价值。方法选择2007年1月—2008年12月共190例三支病变和(或)左主干病变的冠心病患者根据其造影结果计算SYNTAX积分,分别按照本研究人群SYNTAX积分总体分布三分位数值划分及SYNTAX研究人群三分位数值划分的不同分数段SYNTAX积分研究患者的主要不良心脑血管事件(包括死亡、非致命性心肌梗死、再次血运重建、脑血管事件)发生率,比较两者对主要不良心脑血管事件的预测作用。结果 (1)按照本研究人群SYNTAX积分总体分布三分位数值划分低分组(0~20.5)、中分组(21.0~31.0)及高分组(≥31.5)的主要不良心脑血管事件发生率分别为9.1%、16.2%及30.9%,SYNTAX积分能预测MACCE发生率(log rank P=0.006),多因素Cox比例风险回归分析结果显示,SYNTAX积分仍可预测MACCE发生率〔HR=2.07,95%CI(1.25,3.44),P=0.005〕;ROC曲线下面积=0.667〔95%CI(0.564,0.770),P=0.004〕。(2)按照SYNTAX研究人群三分位数值划分低分组(0~22)、中分组(23~32)及高分组(≥33)的主要不良心脑血管事件率分别为15.7%、12.9%及28.6%,此划分法不能预测MACCE的发生率(log rank P=0.09),多因素Cox比例风险回归分析结果显示,根据SYNTAX研究的分数段划分方法不能预测本人群MACCE发生率〔HR=1.47,95%CI(0.94,2.32),P=0.10〕;ROC曲线下面积=0.593〔95%CI(0.475,0.710),P=0.11〕。结论对于本研究190例三支病变和(或)左主干病变经PCI治疗的患者,根据本研究SYNTAX积分总体分布三分位数值的划分法(0~20.5,21.0~31.0,≥31.5)对MACCE有预测作用,而SYNTAX研究中的三分位数值划分法(0~22,23~32,≥33)对MACCE无预测作用。 相似文献

目的研究心脏外科与介入治疗狭窄冠脉研究(SYNTAX)积分以及总体危险分类系统(global riskclassification,GRC)对左主干和(或)三支病变的冠心病患者经皮冠状动脉介入治疗(PCI)预后的预测作用及两者的比较。方法回顾性分析2007年1月—2008年12月在北京安贞医院心内科行PCI的左主干和(或)三支病变的冠心病患者共190例。根据冠状动脉造影结果计算SYNTAX积分,通过SYNTAX积分联合欧洲心脏手术危险评估系统(EuroSCORE)得到GRC。随访终点为主要不良心脑血管事件(MACCE),包括死亡、非致命性心肌梗死、再次血运重建、脑卒中。结果 SYNTAX积分低、中、高分组的MACCE发生率分别为9.1%、16.2%及30.9%,单因素及多因素分析结果均显示SYNTAX积分是MACCE的独立预测因子〔分别为:HR=2.15,95%CI(1.30,3.54),P=0.003;HR=2.07,95%CI(1.25,3.44),P=0.005〕。GRC低、中、高分组的MACCE发生率分别为17.8%、14.2%及46.1%,单因素及多因素分析结果均显示GRC是MACCE的独立预测因子〔分别为:HR=1.94,95%CI(1.22,3.50),P=0.007;HR=1.94,95%CI(1.15,3.27),P=0.013〕。SYNTAX积分ROC曲线下面积(AUROC)为0.667〔95%CI(0.564,0.770),P=0.004〕,GRC AUROC为0.617〔95%CI(0.512,0.736),P=0.046〕。结论SYNTAX积分和GRC对冠状动脉左主干和(或)三支病变患者行PCI治疗后的MACCE均有预测作用,GRC不优于SYNTAX积分。 相似文献

目的比较多支冠状动脉病变患者实施经皮冠状动脉介入术的不同血运重建方式(完全性或不完全性)对其远期预后的影响。方法540例冠心病患者行选择性冠状动脉内支架术,其中多支病变完全性血运重建组(CR组,247例),多支病变不完全性血运重建组(IR组,293例),对比分析两组患者经皮冠状动脉介入(PCI)术后远期随访结果。结果与CR组比较,IR组患者中冠状动脉病变处数、严重程度、三支病变比例、左主干病变、慢性闭塞病变、分叉病变数量均明显升高(P〈0.05)。随访(32.4±2.4)个月,IR组左室射血分数明显低于CR组(P〈0.05)。IR组再次血运重建比例和不良心血管事件(MACE)发生率均显著高于CR组(P〈0.05)。Logistic回归分析发现不完全血运重建是MACE、再次血运重建的危险预测因子(P〈0.05),但未见对远期死亡、再发心肌梗死的影响有统计学意义。结论通过行冠状动脉介入术实现完全性血运重建的冠状动脉多支病变患者长期预后效果优于不完全性血运重建者。不完全血运重建是MACE事件、再次血运重建的预测因子。 相似文献

Objective To observe the ang/ographic characteristics and the long-term clinical outcomes following coronary stenting in non-diabetic (non-DM) and type 2 diabetic (DM) patients with coronary artery disease. Methods This cohort study enrolled 1172 consecutive patients with coronary heart disease underwent elective coronary stenting (249 type 2 DM and 923 non-DM). The angiographic characteristics and the long-term clinical follow-up results were compared between non-DM and DM patients. Results The follow-up period was (39.2±6.4) months (6-83 months), follow-up rate was 90.3% in DM and 91.0% in uon-DM group (P>0.05). Compared with non-diabetic patients, there were significantly higher incidences of 2-veasel (P = 0.029) and 3-vessel (P = 0.013) diseases of coronary artery, severe stenosis lesion(P =0.012), chronic total obstructive lesion(P =0.044) and long lesion(P =0.001), in-stent restenosis (ISR,P =0.000) and revascularization(P =0.000) and MACE(P =0.000) in DM patients. COX multiple factorial analysis showed that DM is independent risk factor for ISR (P = 0.000), revascularization(P =0.001) and MACE(P=0.003). Conclusions CHD patients with type 2 DM are associated with multi- and more severe vessel lesions. Type 2 DM is also an independent risk factor for increased ISR, revascularization and MACE post stenting. 相似文献

目的 比较单支和多支冠状动脉病变患者经皮冠状动脉介入术(PCI)后的远期预后以及实施完全性或不完全性血运重建对后者长期临床疗效的影响. 资料与方法 959例冠心病患者行选择性冠状动脉内支架置入术,其中单支病变组(single-vessel disease,SVD)362例,多支病变完全性血运重建组(complete revascularization,CR)291 例,多支病变不完全性血运重建组(incomplete revascularization,IR)306例,对比分析3组患者PCI手术后2.5年随访结果. 结果 与CR组比较,IR组患者中冠状动脉病变严重程度、3支病变比例、左主干病变、分叉病变数量均高 (P<0.05) ,病变数目少而平均置入支架数多(P<0.05).SVD组冠状动脉病变平均狭窄程度重而植入支架长度和直径均小于另两组(P<0.05).IR组再发心绞痛(P<0.05)、再次血运重建比例(P<0.01)和MACE事件发生率(P<0.05)均显著高于另两组. 结论 通过行PCI术实现完全性血运重建的多支冠状动脉病变患者长期预后效果与单支病变者类似,优于不完全性血运重建者. 相似文献
