摘 要:目的评估半量重组组织型纤溶酶原激活剂阿替普酶(It—PA)静脉溶栓后早期(3—24h)经皮冠状动脉介入(PCI)治疗急性ST段抬高型心肌梗死(STEMI)的疗效。方法选择2010年1月~2013年4月泉州市第一医院心内科76例高危的STEMI患者,接受半量rt—PA(50mg)静脉溶栓后早期PCI(半剂量组),和同期50例接受全量rt-PA(100mg)静脉溶栓后早期PCI(常规剂量组)进行对比分析,比较二者冠脉开通率、住院期间以及30d主要心血管事件(再发心肌梗死、再发心绞痛、新发心力衰竭或原有心力衰竭加剧、心血管死亡)以及住院期间出血并发症的差别。采用t检验进行两组显著性比较。结果半剂量组冠脉开通率和住院期间出血事件发生率低于常规剂量组[61.8%(47/76)比82.0%(41/50),P=0.018;7.9%(6/76)比22.0%(11/50),P=0.020],30d主要心血管事件发生率[36.8%(28/76)比38.0%(19/50)]两组间比较差异均无统计学意义(P〉0.05)。结论半剂量rt—PA溶栓联合早期PCI治疗STEMI可临床获益,且减少出血并发症。Objective To investigate the feasibility and safety of early percutaneous coronary intervention (PCI) within 3-24 hours after half-dose recombinant tissue plasminogen activator (rt-PA) fibfinolysis in acute ST-elevation myocardial infarction (STEMI). Methods 76 high risk patients with STEMI received half- dose ( 50 rag) rt- PA fibrinolysis ( half- dose group ) and 50 high risk patients with STEM I received routine-dose (100 mg) rt-PA fibrinolysis (routine-dose group). All patients received PCI within 3-24 hours after thrombolysis. Results The recanalizing rate of infarct related artery (IRA) was lower in half-dose group than that in routine-dose group during hospitalization[ 61.8% (47/76) vs 82. 0% (41/50) , P = 0.018 ] . Howeyer, the complication of hemorrhage in half-dose group was significantly lower than that in routinedose group [ 7.9% ( 6/76 ) vs 22. 0% ( 11/50 ), P = 0. 020 ]. There were no significant differences (P 〉 0.05 ) in the outcome of the. major adverse cardiovascular events (MACE) [ 36.8% ( 28/ 76) vs 38.0% (19/50)] (including re-infraction and ischemia, heart failure, cardiovascular mortality) between two groups at 30 day clinical follow-up. Conclusion Early PCI after half-dose rt-PA thrombolysis may improve clinical outcomes, reduce hemorrhage complications.
