Nevertheless, the clinical outcomes of DEB have seldom been compared to those of new-generation drug-eluting stent （DES）. Thus, this meta-analysis aimed to evaluate the safety and efficacy of DEB compared to those of new-generation DES in the treatment of ISR. Methods： A comprehensive search of electronic databases including PubMed, EMBASE, and Cochrane Library up to November 2, 2017 was performed to identify pertinent articles comparing DEB to new-generation DES for the treatment of ISR. In addition, conference proceedings for the scientific sessions of the American College of Cardiology, American Heart Association, European Society of Cardiology, Transcatheter Cardiovascular Therapeutics, and EuroPCR were also searched. The primary endpoint was target lesion revascularization （TLR） at the longest follow-up. Dichotomous variables were presented as risk ratios （RRs） with 95% confidence intervals （C/s）, while the overall RRs were estimated using the Mantel-Haenszel random-effects model. Results： Five randomized controlled trials （RCTs） and eight observational studies involving 2743 patients were included in the present meta-analysis. Overall, DEB was comparable to new-generation DES in terms ofTLR （RR = 1.24, 95% CI： 0.89-1.72, P = 0.21 ）, cardiac death （RR = 1.55, 95% CI： 0.89-2.71, P= 0.12）, major adverse cardiovascular event （RR = 1.21,95% CI： 0.98-1.48, P = 0.07）, myocardial infarction （RR = 1.12, 95% CI： 0.72-1.76, P = 0.62）, and stent thrombosis （RR = 0.95, 95% CI： 0.38-2.42, P associated with higher risk of all-cause mortality than new-generation DES （RR = 1.65, 95% CI： 1.09-2.50, P = true in the real-world observational studies （RR = 1.79, 95% CI： 1.12-2.88, P = 0.02）. In RCTs, however, no found between the two treatment strategies in the risk of all-cause mortality. 0.92）. However, DEB was 0.02）. This was especially significant difference was Conclusions： The current meta-analysis showed that DEB and new-generation DES had comparable safety and efficacy for the treatment of ISR in RCTs. However, treatment with DEB was associated with higher risk of all-cause mortality in the real-world nonrandomized studies.展开更多

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）. PC/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 = 0.03 l） 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.展开更多

Methods: From May 2014 to May 2015, 200 Chinese clinicians from two hospitals were enrolled to complete a survey on their attitude towards SDM. We conducted the survey via face-to-face interviews before and after an educational intervention on SDM among young Chinese clinicians. The clinicians were asked to give the extent of agreement to SDM. They also gave the extent of difficulty in using decision aids (DAs) during the SDM process. The variation in the range of responses to each question before and after the SDM intervention was recorded. The frequency of changed responses was analyzed by using JMP 6.0 software. Data were statistically analyzed using Chi-square and Mann—Whitney U tests, as appropriate to the data type. Multiple logistic regressions were used to test for those factors significantly and independently associated with preference for an approach for each scenario. Results: Of the 200 young Chinese clinicians sampled, 59.0% indicated a preference for SDM and a desire to participate in SDM before receiving education or seeing the DA, and this number increased to 69.0% after seeing the DA with the sample video of the SDM process on Statin Choice. However, 28.5% of the respondents still reported that, in their current practice, they make clinical decisions on behalf of their patients. The clinicians who denied a desire to use the DA stated that the main barriers to implement SDM or DA use in China are lack of time and knowledge of SDM.展开更多
