We investigated the medium term clinical efficacy and safety of Firebird sirolimus eluting stent (SES) in coronary artery disease. Methods The sample was 509 consecutive patients with coronary artery disease (CAD) who were treated by Firebird SES and finished three-year clinical follow-up. The occurrences of major adverse cardiac events (MACE) and Academic Research Consortium defined stent thrombosis (ST) were evaluated in patients with and without diabetes mellitus. Results Three hundred and thirty three patients (65. 4%) were treated by Firebird SES by off label indications. Angiographic success was achieved in 98.3% of the lesions. MACE and target vessel revascularization rates at 6-month, 1 year's and 3 years' clinical follow-up were 2.4% and 1.4%, 4.1% and 2.8%, 7.9% and 5.1%, respectively. The cumulative 3-year MACE free survival rate was 92.1%. After 3 years, DM patients had significantly higher rates of MACE (13.7% vs 6.4%, P 〈0.05) and TVR (9.8% vs 4.0%, P 〈0.05) and the cumulative MACE free survival rate was very significantly lower in the DM group (86.4% vs 93;6%, P 〈0.05). ST occurred in 7 patients (1.4%) at the end of 3 years' follow-up, 5 of them had definite ST with 4 cases presenting with myocardial reinfarction and 1 with unstable angina, the other 2 with probable ST had reinfarction in the stented coronary territory without angiographic follow-up. There was no difference in occurrence of ST between off label (1.5%) and on label groups (1.1%, P=-0.07). Conclusions In daily practice, about 2/3 of patients were treated by Firebird SES by off label indications. Medium term clinical follow-up of 3 years indicated CAD patients treated by Firebird SES had a low MACE and acceptable ST rate. DM patients had higher rates of adverse events and than non DM.展开更多

This study was conducted to evaluate whether Tongxinluo (TXL) treatment around the transplantation of mesenchymal stem cells (MSCs) can improve survival and subsequent activities of implanted cells in swine hearts with acute myocardial infarction (AMI) and reperfusion. Methods Twenty-eight Chinese mini-pigs were divided into four groups including a control group (n=7); group 2, administration of low-close TXL alone from the 3rd day prior to AMI to the 4th day post transplantation (n=-7); group 3, MSCs alone (n=-7) and group 4, TXL + MSCs (n=7). AMI models were made by occlusion of the left anterior descending coronary artery for 90 minutes. Autologous bone marrow-MSCs (3×10^7 cells/animal) were then injected into the post-infarct myocardium immediately after AMI and reperfusion. The survival and differentiation of implanted cells in vivo were detected by immunofluorescent analysis. The data of cardiac function were obtained at baseline (1 week after transplantation) and endpoint (6 weeks after transplantation) by single photon emission computed tomography (SPECT) and magnetic resonance imaging (MRI). Apoptosis was detected by TUNEL assay and the oxidative stress level was investigated in the post-infarct myocardium at endpoint. Results At endpoint, there was less fibrosis and inflammatory cell infiltration with more surviving myocardium in group 4 than in the control group. In group 4 the survival and differentiation of implanted MSCs were significantly improved more than that seen in group 3 alone (P〈0.0001); the capillary density was also significantly greater than in the control group, group 2 or 3 both in the infarcted zone (P〈0.0001) and the peri-infarct zone (P〈0.0001). MRI showed that parameters at baseline were not significantly different between the 4 groups. At endpoint, regional wall thickening and the left ventricular ejection fraction were increased while the left ventricular mass index, dyskinetic segments and infarcted size were decreased only in group 4 compared with control group (P〈0.0001). SPECT showed that the area of perfusion defect was significantly decreased at endpoint only in group 4 compared with control group (P〈0.0001). TUNEL assay indicated that TXL administration significantly decreased cell apoptosis in peri-infarct myocardium in groups 2 and 4. Furthermore, superoxide dismutase (SOD) significantly increased and malondialdehyde (MDA) decreased in groups 2 and 4 by the administration of TXL. Conclusions Our study demonstrates the following: (1) immediate intramyocardial injection of MSCs after AMI and reperfusion resulted in limited survival and differentiation potential of implanted cells in vivo, thus being incapable of beneficially affecting post-hearts; (2) TXL-facilitation resulted in a significant survival and differentiation potential of implanted cells in vivo via inhibition of apoptosis and oxidative stress, accompanied by significant benefits in cardiac function.展开更多

文摘目的血小板功能检测指导心脏外科手术治疗的价值,目前仍存在争议,相关研究的中国患者的数据较少。本文旨在探讨血栓弹力图(TEG)对CABG术后输血的预测价值。方法入选阜外医院61例行CABG的患者,所有患者术前24 h内行TEG检测,临床主要终点为术后输血。结果CABG术后输血共14人(23.0%)。输血组患者TEG检测的平均二磷酸腺苷诱导的血凝块最大强度[MA(ADP)]值显著低于未输血组(28.67±18.04 vs 37.21±12.64,P=0.023)。选取MA(ADP)值31mm为划分点,≤31mm组患者术后输血风险明显较>31mm组增高(37.5%vs 13.5%,P=0.030)。多因素回归分析显示MA(ADP)≤31mm为CABG术后输血的独立预测因素,MA(ADP)≤31mm患者术后输血的风险是MA(ADP)>31mm患者的8.352倍(95%CI:1.670-41.780,P=0.010)。结论TEG血小板功能检测对CABG术后出血有一定的预测价值;MA(ADP)≤31mm为CABG术后输血的独立危险因素。
