Background:
There are limited data on longer-term outcomes (>5 years) for patients with unprotected left main coronary artery (ULMCA) disease who underwent percutaneous coronary intervention (PCI) in the drug-eluting stents (DES) era. This study aimed at comparing the long-term (>5 years) outcomes of patients with ULMCA disease underwent PCI with DES and coronary artery bypass grafting (CABG) and the predictors of adverse events.Methods:
All consecutive patients with ULMCA disease treated with DES implantation versus CABG in our center, between January 2003 and July 2009, were screened for analyzing. A propensity score analysis was carried out to adjust for potential confounding between the two groups.Results:
Nine hundred and twenty-two patients with ULMCA disease were enrolled for the analyses (DES = 465 vs. CABG = 457). During the median follow-up of 7.1 years (interquartile range 5.3–8.2 years), no difference was found between PCI and CABG in the occurrence of death (P = 0.282) and the composite endpoint of cardiac death, myocardial infarction (MI) and stroke (P = 0.294). Rates of major adverse cardiac and cerebrovascular events were significantly higher in the PCI group (P = 0.014) in large part because of the significantly higher rate of repeat revascularization (P < 0.001). PCI was correlated with the lower occurrence of stroke (P = 0.004). Multivariate analysis showed ejection fraction (EF) (P = 0.012), creatinine (P = 0.016), and prior stroke (P = 0.031) were independent predictors of the composite endpoint of cardiac death, MI, and stroke in the DES group, while age (P = 0.026) and EF (P = 0.002) were independent predictors in the CABG group.Conclusions:
During a median follow-up of 7.1 years, there was no difference in the rate of death between PCI with DES implantation and CABG in ULMCA lesions in the patient cohort. CABG group was observed to have significantly lower rates of repeat revascularization but higher stroke rates compared with PCI. EF, creatinine, and prior stroke were independent predictors of the composite endpoint of cardiac death, MI, and stroke in the DES group, while age and EF were independent predictors in the CABG group. 相似文献目的 探讨显微手术治疗颅内动脉瘤的临床效果,并分析影响术后脑血管痉挛(CVS)发生的相关因素及对预后的影响。方法 回顾性分析2009年5月-2013年5月于郑州人民医院收治的128例颅内动脉瘤患者的临床资料。评价总体治疗效果,并分别应用单因素及Logistic多因素分析影响患者术后CVS发生的相关因素及对预后的影响。结果 128例患者总体治疗效果良好,术后发生CVS 32例(25.00%),与非CVS组比较,CVS组术后治愈率显著下降,而死亡率显著上升,差异有统计学意义(P <0.05)。经单因素分析可知,影响患者显微手术术后CVS发生的相关因素包括年龄、Hunt-Hees分级、Fisher’s分级、动脉瘤位置、手术时机、感染、基础疾病、终板造瘘、腰穿次数、血糖及白细胞水平。经Logsitic多因素进一步分析可知,Hunt-Hees分级、Fisher’s分级、动脉瘤位置、终板造瘘、腰穿次数是影响显微手术治疗颅内动脉瘤术后CVS发生的独立危险因子,并影响预后。结论 显微手术治疗颅内动脉瘤临床效果良好,但须防范Hunt-Hees分级、Fisher’s分级、动脉瘤位置、终板造瘘、腰穿次数等影响术后CVS发生的独立危险因素,改善颅内动脉瘤患者预后。
相似文献目的 探讨辛伐他汀对肥胖哮喘小鼠气道炎症的作用及其机制。方法 将60只C57BL/6J小鼠随机分为空白对照组、肥胖哮喘组、地塞米松治疗组和辛伐他汀治疗组。其中,肥胖哮喘组、地塞米松治疗组、辛伐他汀治疗组小鼠采用卵蛋白致敏、激发的方法和高脂饮食诱导建立肥胖哮喘模型。地塞米松治疗组每日给予地塞米松(0.5 mg/kg)饮水干预,辛伐他汀治疗组每日给予辛伐他汀(40 mg/kg)饮水干预,其余两组正常饮水。治疗4周后,计数存活小鼠,采外周血生化分析仪测定血糖、血脂、肝功能水平;收集支气管肺泡灌洗液,计数支气管肺泡灌洗液中白细胞总数及各炎症细胞所占比例;肺病理切片观察小鼠气道炎症和结构变化。结果 肥胖哮喘组、地塞米松治疗组、辛伐他汀治疗组气道炎症评分、回抽收集灌洗液中白细胞总数及中性粒细胞百分比、血清总胆固醇水平均较空白对照组升高,其中辛伐他汀治疗组上述指标较肥胖哮喘组、地塞米松治疗组下降,差异有统计学意义(P <0.05)。且总胆固醇水平与支气管肺泡灌洗液中中性粒细胞百分比呈正相关(r =0.724,P =0.020)。结论 辛伐他汀治疗可以减轻肥胖哮喘的气道炎症,改善哮喘病情,这一作用与其降低血脂水平有一定关系。
相似文献Microvascular decompression (MVD) is the first choice of surgery for hemifacial spasm (HFS). MVD surgery for vertebral artery (VA)-associated HFS is more difficult than for non-VA-associated HFS. There is controversy about the cure rate and complication of MVD for HFS in previous studies. We searched PubMed, Web of Science, and Embase for relevant publications. Based on the search results, we compared the outcomes of MVD for VA-associated HFS and non-VA-associated HFS. At the same time, we analyzed spasm-free rates and the complications and assessed the relationship between VA-associated HFS and gender, left side, and age. For analysis, six studies that included 2952 patients in the VA-associated group and 604 in the non-VA-associated group were selected. The effective rate of MVD was not significantly different between both groups (OR?=?1.16, 95% CI 0.81–1.67, P?=?0.42). Compared to non-VA-associated group, the transient complications (OR?=?0.64, 95% CI 0.46–0.89, P?=?0.008) and permanent complications (OR?=?0.28, 95% CI 0.15–0.54, P?=?0.0001) occurred more frequently in VA-associated group. The rate of hearing loss was significantly higher in VA-associated HFS than non-VA-associated HFS (OR?=?0.35, 95% CI 0.19–0.64, P?=?0.0007); the facial paralysis after operation was not significantly different between both groups (OR?=?1.25, 95% CI 0.91–1.72, P?=?0.17). There were older patients (WMD?=?3.67, 95% CI 3.29–4.05, P?<?0.00001) and more left-sided HFS (OR?=?0.23, 95% CI 0.19???0.29, P?<?0.0002) in the VA-associated HFS group than non-VA-associated HFS group, while the non-VA-associated HFS group was female-dominated (OR?=?1.58, 95% CI 1.32???1.89, P?<?0.00001). Both groups achieved good results in MVD cure rates. In VA-associated HFS, the complication rate of decompression and the rate of hearing loss after operation were higher than in non-VA-associated HFS, but the facial paralysis after operation was similar in both groups, and most complications were transient and disappeared during follow-up. VA-associated HFS is more prevalent in older adults, less prevalent in women, and more predominantly left-sided. More clinical studies are needed to better compare the efficacy and complication of MVD between both groups.
