目的探讨急诊经皮冠状动脉介入(PCI)治疗对急性心肌梗死(AMI)者窦性心率震荡的影响。方法入选108例AMI患者,分成3组:急诊PCI组48例(A组)、延迟PCI组30例(B组)、药物治疗组30例(C组),均有单发室性期前收缩(PVS),比较发病后3周内3种不同疗法对震荡起始(TO)、震荡斜率(TS)、心率变异性时域指标(SDNN)和左心室射血分数(LVEF)等指标的影响。结果A组TO(-2.12%±3.08%)低于B组(-1.37%±1.18%)和C组(0.96%±2.35%),A组TS(10.28±6.34ms/R-R)高于B组和C组(7.92±4.21ms/R-R和4.29±2.87ms/R-R),差异均有非常显著性意义(P<0.01);B组上述指标与C组差异也有显著性(P<0.05)。A组SDNN(138.26±30.23ms)和LVEF(60.89%±14.80%)均显著高于B组(108.43±31.68ms,53.38%±15.32%)和C组(81.07±28.53ms,49.96%±13.75%),P<0.05。结论AMI患者急诊PCI或延迟PCI对窦性心率震荡各参数的改善均优于药物治疗,急诊PCI的改善作用更为显著。
Objective To investigate the effect of emergency percutaneous coronary intervention (PCI) on sinus rhythm in patients with acute myocardial infarction (AMI). Methods A total of 108 patients with AMI were enrolled and divided into three groups: 48 patients in the PCI group (group A), 30 patients in the delayed PCI group (group B) and 30 patients in the drug treatment group (group C) (PVS). The effects of three different therapies on the onset of heart rate (TO), concussion slope (TS), heart rate variability (SDNN) and left ventricular ejection fraction (LVEF) . Results The TO (2.12% ± 3.08%) in group A was lower than that in group B (-1.37% ± 1.18%) and group C (0.96% ± 2.35% And group C (7.92 ± 4.21ms / RR and 4.29 ± 2.87ms / RR respectively). There was also significant difference between group B and group C (P <0.05). SDNN (138.26 ± 30.23ms) and LVEF (60.89% ± 14.80%) in group A were significantly higher than that in group B (108.43 ± 31.68ms, 53.38% ± 15.32%) and group C (81.07 ± 28.53ms, 49.96% ± 13.75% ), P <0.05. Conclusion The improvement of sinus arrhythmia parameters in AMI patients treated with emergency PCI or delayed PCI is better than that of drug treatment. The improvement of emergency PCI is more significant.
