目的探讨早期冠状动脉血栓抽吸联合支架置入术对急性心肌梗死患者心脏节律的影响。方法对79例急性心肌梗死并冠状动脉血栓患者均行经皮冠状动脉介入术(percutaneous coronary intervention,PCI)治疗,其中38例行急诊直接冠状动脉血栓抽吸术联合PCI介入术(急诊介入组),41例行择期PCI介入术(择期介入组);观察2组术后2周及1a心律失常发生率。结果术后2周及1a择期介入组心律失常发生率均高于急诊介入组(χ2=12.012,P<0.05;χ2=11.737,P<0.05)。结论急诊直接冠状动脉血栓抽吸术联合PCI治疗急性心肌梗死并冠状动脉血栓安全、有效,可降低心律失常发生率。
Objective To investigate the effect of early coronary thrombus aspiration and cardiac stenting on cardiac rhythm in patients with acute myocardial infarction. Methods A total of 79 patients with acute myocardial infarction and coronary artery thrombosis underwent percutaneous coronary intervention (PCI). 38 patients underwent emergency PCI and PCI intervention (emergency intervention group) Forty-one patients underwent elective PCI intervention (elective intervention group). The incidence of arrhythmia was observed at 2 weeks after operation in both groups. Results The incidence of arrhythmia in the intervention group at 2 weeks and at 1-year follow-up was significantly higher than that in the emergency intervention group (χ2 = 12.012, P <0.05; χ2 = 11.737, P <0.05). Conclusions Emergency direct coronary thrombectomy combined with PCI in the treatment of acute myocardial infarction and coronary artery thrombosis is safe and effective and can reduce the incidence of arrhythmia.
