【摘要】 目的:探讨急性ST段抬高性心肌梗塞(STEMI)急诊经皮冠状动脉介入治疗(PCI)时临时心脏起搏应用的概率。方法:本研究为前瞻性、对照性临床研究,连续性入选197例STEMI拟行急诊PCI的患者,发病4h内行急诊PCI的患者归入A组,发病4～12h行急诊PCI的患者归入B组。比较两组临时心脏起搏应用的差别。结果:A组入选53例,B组144例,两组基础临床资料、造影及介入治疗结果比较的情况相仿,各临床指标差异无显著性(P>0.05),A组需临时心脏起搏治疗的患者比例明显高于B组(41.5%∶23.6%,P<0.05)。结论:对急性心肌梗塞发病拟行PCI,尤其拟在4h内进行者,建议备放心脏起搏导管,在出现起搏适应证时,及时进行临时心脏起搏,以免耽误抢救。更多还原

【Abstract】 Objective:To observe the probability of temporary cardiac pacing during emergency percutaneous coronary intervention (PCI) for acute ST elevation myocardial infarction (STEMI) patients. Methods: A total of 197 consecutive STEMI patients were randomly assigned for study. Patients undergoing emergency PCI in 4 h were assigned to group A(53 cases), the patients undergoing emergency PCI in 4-12 h were assigned to group B(144 cases). Compared the difference for applying temporary cardiac pacing between the two groups. Results: Baseline characteristics and angiographic characteristics showed no significant difference between the two groups (P>0.05). The proportion called for temporary cardiac pacing in group A was significantly higher than that of group B (41.5% vs. 23.6%, P<0.05). Conclusion: The result suggests for acute myocardial infarction patients who undergo emergency percutaneaus coronary intervention especially in 4 h must preparation cardiac pacing pipe, when cardiac pacing indications occur may promptly carry out temporary cardiac pacing.更多还原
