Effects of upstream tirofiban versus downstream tirofiban on myocardial damage and 180-day clinical outcomes in high-risk acute coronary syndromes patients undergoing percutaneous coronary interventions

Chinese Medical Journal 2009年第15期122卷 1732-1737页

作者： LIU Tao XIE ying ZHOU Yu-jie LI Yue-ping MA Han-ying GUO Yong-he LIU Yu-yang zhao ying-xin SHI Dong-mei Department of Geriatric Cardiology Beijing Anzhen Hospital Affiliated to Capital Medical University Beijing 100029 China

Background For patients with moderate to high-risk acute coronary syndromes （ACS） who undergo early, invasive treatment strategies, current guidelines recommend the usage of glycoprotein （GP） lib/Ilia inhibitors as an upstream treatment for a coronary care unit or as an downstream provisional treatment for selected patients who are undergoing percutaneous coronary intervention （PCI）. The relative advantage of either strategy is unknown. The purpose of this study was to evaluate the effects of upstream tirofiban versus the effects of downstream tirofiban on myocardial damage and 180-day major adverse cardiovascular events （MACE） after PCI in high-risk non-ST-segment elevation ACS （NSTE-ACS） undergoing PCI. Methods From July 2006 to July 2007, 160 high-risk NSTE-ACS undergoing PCI were randomized to receive upstream （within 4-6 hours before coronary angiography） tirofiban or downstream （the guidewire crossing the lesion） tirofiban, to evaluate the extent of myocardial damage after PCI by quantitatively and qualitatively analyzing the value of cardiac troponin I （cTnl） as well as MB isoenzyme of creatine kinase （CK-MB） before and after PCI. The incidences of 24-hour, 3-day, 7-day, 30-day and 180-day MACE after PCI were followed up and the rates of bleeding complications and thrombocytopenia during tirofiban administration were recorded. Results The peak release and cumulative release of cTnl levels within 48 hours after PCI were significantly lower with upstream tirofiban than downstream tirofiban （0.45 vs 0.63 and 0.32 vs 0.43, respectively; P 〈0.05）. Post-procedural cTnl elevation within 48 hours was significantly less frequent among patients who received the upstream tirofiban than those who received the downstream tirofiban （66.3% vs 87.5%, P 〈0.05）. The peak and cumulative release of CK-MB levels as well as post-procedural CK-MB elevation within 48 hours after PCI were not significantly different between the two groups （16 vs 14,5 vs 3 and 26.3% vs 36.3%, respecti

采用三维视频显微镜、粗糙度轮廓仪和电化学测试研究溴化锂溶液中不同温度条件下Ti-6Al-4V微观空蚀形貌、粗糙度以及电化学腐蚀行为,探讨温度对空蚀的影响机理。结果表明:温度的影响随空蚀时间增加不断加强,240 min时最为显著,之后影响减弱并趋于稳定。温度升高,空泡溃灭产生的微射流冲击强度增大,使表面钝化膜更易被破坏,同时腐蚀作用加速了点蚀形成,导致表面局部应力集中和更多电化学电池的产生,从而促进了力学和腐蚀因素,两者的协同作用加速了空蚀破坏。空蚀破坏程度在温度55℃时达到最大值,继续升高温度,腐蚀因素仍被促进,但微射流对表面的冲击强度减弱,对表面钝化膜的破坏作用降低,由于力学因素在空蚀中占据主导地位,因此使空蚀速率得到减缓。
