急性心肌梗死(AMI)病情危重,病死率高,且发病率逐年上升,严重危及患者生命安全。目前直接经皮冠状动脉介入治疗(PCI)已经成为治疗急性心梗最为有效的方法。然而,在急诊PCI术的施行过程中,因冠脉内血栓负荷较重,引发的无复流现象仍是危及患者生命的重大问题。目前指引导管内及外周静脉注射替罗非班为处置冠脉无复流的传统办法,但由于血流难以或难以较快输注冠脉远端,因此药物难以发挥即
Acute myocardial infarction (AMI) in critical condition, high mortality, and the incidence increased year by year, seriously endangering patients’ lives and safety. Direct percutaneous coronary intervention (PCI) has become the most effective treatment of acute myocardial infarction. However, during the emergency PCI, the no-reflow phenomenon caused by heavy coronary thrombus load is still a serious problem that endangers the life of patients. At present, the guideline of intravenous administration of tirofiban in and outside the catheter is a traditional treatment of coronary artery without reflow. However, due to difficult or difficult blood flow to infuse the distal coronary artery, the drug is hard to exert
