经PCI治疗ST段抬高型心肌梗死患者碎裂QRS波与SYNTAX Ⅱ评分的关系

Relationship between Fragmented QRS and SYNTAX Ⅱ score in patients with ST-segment elevation myocardial infarction treated with PCI

目的探讨经皮冠状动脉介入治疗(PCI)ST段抬高型心肌梗死(STEMI)患者碎裂QRS(fQRS)与SYNTAX Ⅱ评分的相关性。方法84例PCI治疗的STEMI患者在PCI前、后进行标准十二导联心电图(ECG)检测。评估所有患者SYNTAX评分和SYNTAX Ⅱ评分。所有患者行经胸超声心动图检查。结果20例(23.8%)STEMI患者ECG检查有fQRS。SYNTAX Ⅱ评分中位数为27(22.9~33.8)。fQRS(+)组SYNTAX Ⅱ评分高于fQRS(-)组(35.3 VS 25.8)(P<0.05)。高SYNTAX Ⅱ评分STEM患者,ECG上fQRS导联数量也相应地增加。结论经PCI治疗STEMI患者fQRS及fQRS导联数量与SYNTAX Ⅱ评分相关。

Objective To evaluate the relation between fragmented QRS(fQRS)and syntax scoreⅡ(SSⅡ)in patients with ST elevation myocardial infarction(STEMI)treated with PCI.Methods This study enrolled 84 STEMI patients treated with percutaneous coronary intervention(PCI).The standard 12-lead electrocardiograms(ECG)were obtained from all patients before and after PCI.SS and SSⅡwere calculated in all patients.Transthoracic echocardiography was performed to all patients.Results Twenty patients(23.8%)had fQRS on their ECGs.The median SSⅡwas 27(22.9~33.8).SSⅡvalues in the fQRS(+)group were significantly higher than that in the fQRS(-)group(35.3 VS 25.8,P<0.05).Also,in patients with higher SSⅡ,there was significantly higher number of fQRS leads on ECGs.Conclusions The presence of fQRS and high number of fQRS leads on ECG may be associated with high SSⅡin STEMI patients treated with PCI.
