血运重建方式对冠心病三支病变患者预后的影响

目的观察不同的冠状动脉血运重建方式——完全血运重建(冠状动脉介入治疗或冠状动脉旁路移植术)或部分血运重建(冠状动脉介入治疗)对冠心病三支病变患者死亡率和心功能的影响。方法共181名三支病变并行血运重建的患者,按血运重建方式分为两组:部分血运重建组行经皮腔内冠状动脉成形术和/或冠状动脉支架置入术,完全血运重建组行冠状动脉旁路移植术或支架置入术。手术后临床随访6~70个月(平均28.6±9.2个月),比较两组随访病例临床终点事件和心功能的差异。结果(1)基线资料:对部分血运重建组123例和完全血运重建组58例进行了临床随访,两组在年龄及性别方面差异无统计学意义。(2)临床事件:部分血运重建组死亡9例(7.32%),完全血运重建组死亡5例(8.62%);部分血运重建组再入院17人(13.8%),完全血运重建组再入院7人(10.3%),两组之间差异均无统计学意义(P>0.05)。选择完全血运重建或部分血运重建对患者28个月的死亡率和心功能无显著影响(P>0.05)。治疗前左室射血分数对患者的死亡率有显著影响(P=0.004,95%CI=0.893~0.978)。结论临床选择冠状动脉完全血运重建或部分血运重建对冠状动脉三支病变患者28个月死亡率和心功能的影响差异无统计学意义,而治疗前左室射血分数是影响其远期预后的重要因素。     

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

目的 探讨冠心病合并2型糖尿病(DM)患者冠状动脉异常程度和冠状动脉内支架术后远期疗效.方法 将行冠状动脉内支架术的1172例冠心病患者分为DM组(249例)和非DM组(923例).对两组的冠状动脉病变情况及远期临床疗效进行比较.结果 与非DM组比较,DM组病变数较多(P=0.046),2支(P=0.029)和3支(P=0.013)病变比例较高,弥漫病变(P=0.001)、慢性闭塞性病变(P=0.044)及重度病变(P=0.012)多见.两组临床随访率差异无统计学意义.与非DM组相比,DM组支架内再狭窄(55.96/万比35.51/万)、再次血运重建(76.18/万比51.55/万)和主要不良心血管事件(85.50/万比61.47/万)的人月发病率均明显增高(均P=0.000).COX多因素回归分析显示,2型DM与支架内再狭窄(P=0.000)、再次血管重建(P=0.001)、主要不良心血管事件(P=0.003)密切相关,但与死亡无明显相关.结论 合并2型DM的冠心病患者冠状动脉病变较重.2型DM是支架内再狭窄、再次血管重建和主要不良心血管事件的独立预测因子.     

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.
