Effect of a distal protection device on epicardial blood flow and myocardial perfusion in primary percutaneous coronary intervention 总被引：2，自引：0，他引：2
Objective: The beneficial effect of percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) has been well established, but there is the problem of no-reflow phenomenon which is an adverse prognostic factor in primary PCI. In the present study the effect of a distal protection device (PercuSurge GuardWire; GW) on epicardial blood flow and myocardial perfusion was evaluated. Methods and Results: Patients with AMI were randomly divided into 2 groups, the GW and the control groups. The GW group included 52 patients with AMI who underwent primary PCI with GW protection and the control group included 60 patients who underwent primary PCI without GW protection. Epicardial blood flow in the infarct-related artery (IRA) and myocardial perfusion were evaluated according to the thrombolysis in myocardial infarction (TIMI) flow grade and the myocardial blush grade (MBG). We found TIMI score of 3 was obtained significantly more frequently in the GW group (96%) than in the control group (80%). The MBG score of 3 was obtained also significantly greater in the GW group (65%) than in the control group (33%). Conclusion: Primary PCI with GW protection can significantly improve epicardial blood flow and myocardial perfusion. 相似文献

Computed tomography angiography-guided percutaneous coronary intervention in chronic total occlusion
Ping Li Lu-yue Gai Xia Yang Zhi-jun Sun Qin-hua Jin 《Journal of Zhejiang University. Science. B》2010,11(8):568-574
Objective:The aim of this study is to investigate if dual-source computed tomography(DSCT) could guide the percutaneous coronary intervention(PCI) of chronic total occlusion(CTO).Methods:We enrolled patients who were confirmed to have at least one native coronary artery CTO by DSCT before they underwent selective PCI in the period from December 2007 to October 2008.A CTO was defined as an obstruction of a native coronary artery with no luminal continuity.The CT-guided PCI procedure involved placing CT and fluoroscopic images side-by-side on the screen.DSCT images were analyzed for location,segment,plaque characteristics,calcification,and proximal lumen diameter of the CTO before PCI.The guidewire was advanced and manipulated under CT guidance.The PCI was carried out and the results were compared.Results:Seventy-four CTOs were assessed.PCI was successful in 57 cases of CTOs(77.0%).According to the results,CTOs were divided into two groups:successful-PCI and failed-PCI.All coronary artery paths of CTOs were clearly recognized by DSCT.In the successful-PCI group,soft plaques were detected much more often than those in the failed-PCI group,but fibrous and calcified plaques were seen more often in the failed-PCI group.Calcification severity in CTO segments showed a significant difference between the groups(P=0.014).Calcified plaques were detected in 20(35.1%) lesions in the successful-PCI group.More than 70% of the failures were calcified plaques,of which there were two arc-calcified and one circular-calcified lesions.Occlusions were longer in the failed-PCI group than those in the successful-PCI group [(38.8±25.0) vs.(18.0±15.3) mm,respectively,P0.01].Fewer guidewires were used in the successful-PCI group compared with the failed-PCI group(1.7±1.0 vs.2.5±0.9,respectively,P0.01).The logistic regression analysis indicated that predictors of recanalization of CTOs included occlusion length(P=0.0035,risk ratio(RR)=0.93) and calcification severity(P=0.05,RR=0.27).Multi-linear trends analysis showed that the factors affecting procedural time were CTO location(P=0.0141) and occlusion length(P=0.0035).Conclusions:DSCT could delineate the path of CTOs and characterize plaques.The outcomes of PCI were related to thrombolysis in myocardial infarction(TIMI) flow grade,CTO characteristics,severity of calcified plaques,and the length of occlusive segments.Occlusion length and calcification severity were independent predictors of CTOs.Occlusion length and CTO segments could also help to estimate the duration of interventional procedures. 相似文献

Although cardiac rupture (CR) is a fatal mechanical complication of acute myocardial infarction (AMI), to date no predictive model for CR has been described. CR has common pathological characteristics with major bleeding. We aimed to investigate the relationship between the risk factors of major bleeding and CR. A total of 10 202 consecutive AMI patients were recruited, and mechanical complications occurred in 72 patients. AMI patients without CR were chosen as control group. Clinical characteristics including bleeding-related factors were compared between the groups. The incidences of free wall rupture (FWR), ventricular septal rupture (VSR), and papillary muscle rupture (PMR) were 0.39%, 0.21%, and 0.09%, respectively, and the hospital mortalities were 92.5%, 45.5%, and 10.0%, respectively. Female proportion and average age were significantly higher in the groups of FWR and VSR than in the control group (P<0.01); higher white blood cell count and lower hemoglobin were found in all CR groups (P<0.01). Compared to the control group, patients with CR were more likely to receive an administration of thrombolysis [26.39% vs. 13.19%, P<0.05], and were less likely to be treated with primary percutaneous coronary intervention (PCI) [41.67% vs. 81.60%, P<0.05]. The major bleeding scores (integer scores) of FWR, VSR, and PMR were (17.70±7.24), (21.91±8.33), and (18.60±7.88), respectively, and were significantly higher than that of the control group (11.72±7.71) (P<0.05). A regression analysis identified age, increased heart rate, anemia, higher white blood cell count, and thrombolysis as independent risk factors of CR, most of which were major bleeding-related factors. The patients with CR have a significantly higher risk of hemorrhage compared to the group without CR. Risk of CR after AMI is related to the risk of hemorrhage. 相似文献

目的观察潘南金(门冬氨酸钾镁)对急性心肌梗塞后心律失常、泵功能及死亡率的影响.方法本文对我院1998.3～1999.10月收入CCU病房的40例患者进行单盲、随机分为治疗组和对照组,治疗组第1～5天给予潘南金静脉输注,第6～15天改为口服,检测两组治疗前、第5、10天的血清钾、镁离子浓度,记录治疗前后血压及第一天24hHolter,统计两组并发症及死亡率,所得数据进行统计学处理.结果两组间在年龄、性别、发病时间及合并用药等方面无差异,所有资料具有可比性.治疗组第5、10天的血镁较治疗前及对照组显著增高(P＜0.01),治疗组的心衰、室早、室速较对照组明显减少(P值分别为＜0.05、＜0.01及＜0.05),治疗组再灌注心律失常发生率较对照组减少(P＜0.05),死亡率两组间无显著差异(P＜0.05).治疗组治疗前后血压变化较对照组明显(P＜0.05).结论潘南金可以减少AMI后心衰的发生,改善心功能,减少AMI后室性心律失常的发生.在溶栓的患者,潘南金能减少再灌注心律失常的发生,减小再灌注损伤.但潘南金对血压有较大的影响,尤其血压在正常低限时,静脉输注潘南金可使低血压发生率增加,因此临床应用时需注意. 相似文献

Objective:Percutaneous coronary intervention(PCI) triggers an acute inflammatory response,while sirolimus is known to have anti-inflammatory properties;the inflammatory system response to PCI after sirolimus-eluting stent placement remains unclear.The purpose of this study is to determine the changes in high sensitive C-reactive protein(hs-CRP) and apelin after PCI procedure and drug-eluting stent implantation in patients with and without reduced left ventricular systolic function.Methods:Forty-eight consecutive patients undergoing PCI at the Beijing Anzhen Hospital between July and September 2006 were recruited.Sirolimus-eluting stents were employed in all patients.Blood samples were drawn immediately before and 24 h after the procedure.Plasma hs-CRP and apelin levels were determined by enzyme immunoassay.Results:Paired t-test revealed a significant increase in both hs-CRP and apelin post-procedure(P=0.006 and P0.0001,respectively).Patients with reduced left ventricular ejection fraction(LVEF) had significantly lower baseline apelin levels compared to those with normal ventricular function [(46.8±10.8) vs.(72.0±8.4) pg/ml,P0.001].However,apelin increased to a level similar to the level of those with normal left ventricular systolic function 24 h after the PCI procedure [(86.7±11.6) vs.(85.1±6.1) pg/ml,P=0.72].Conclusions:hs-CRP and apelin levels increased after PCI and sirolimus-eluting stent implantation.Patients with impaired left ventricular systolic function had significantly lower baseline apelin levels,which increased significantly after PCI. 相似文献
