氢氯噻嗪、氯沙坦单用或联用治疗轻中度高血压病患者降压效果及对心脏功能的影响

单一抗高血压药物治疗未能达到目标血压的高血压病患者主张联合用药或应用复方制剂.血管紧张素Ⅱ(AngⅡ)受体拮抗剂海捷亚(氯沙坦和噻嗪类利尿剂氢氯噻嗪的复方制剂,美国默沙东公司生产)在国内临床应用还不十分普及,本研究旨在探讨氢氯噻嗪、氯沙坦单用或联用的降压效果及对心脏功能的影响.     

冠状动脉多支病变患者不同介入性血运重建方式的远期随访比较

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。     

不同分层标准SYNTAX积分对经皮冠状动脉介入治疗复杂冠心病患者的预测价值

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。     

SYNTAX积分和GRC对复杂冠心病患者经皮冠状动脉介入治疗预后的预测作用研究

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。     

冠心病合并2型糖尿病患者冠状动脉内支架术后的远期随访

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.
