Even though the relationship between syntax score (SS) and fragmented QRS (fQRS) has been studied, the relation between syntax score II (SS II) and fQRS in patients with ST elevation myocardial infarction (STEMI) is undefined. We aimed to define the relationship between fQRS and SS II for the evaluation of extension and complexity of coronary artery disease.
This study enrolled 167 patients undergoing primary percutaneous coronary intervention (pPCI) for STEMI. The standard 12-lead electrocardiograms (ECGs) were obtained from all patients before and after PCI. SS and SS II were calculated in all patients. Transthoracic echocardiography was performed to all patients.
Thirty-nine patients (23.4%) had fQRS on their ECGs. The median SS II was 27 (22.9-33.9). SS II values in the fQRS(+) group were statistically significantly higher than that of the fQRS(-) group (35.2 (26.4-47.2) vs. 25.7 (22.1-30.7), p < 0.001). Also, in patients with higher SS II, there was significantly higher number of ECG derivations with fQRS.
The presence of fQRS and high number of derivations with fQRS on ECG may be associated with high SS II in patients undergoing pPCI for STEMI.
尽管已经研究了句法评分（SS）与碎裂QRS波（fQRS）之间的关系，但ST段抬高型心肌梗死（STEMI）患者的句法评分II（SS II）与fQRS之间的关系尚不明确。我们旨在明确fQRS与SS II之间的关系，以评估冠状动脉疾病的范围和复杂性。
本研究纳入了167例行直接经皮冠状动脉介入治疗（pPCI）的STEMI患者。所有患者在PCI术前和术后均记录标准12导联心电图（ECG）。计算所有患者的SS和SS II。所有患者均接受经胸超声心动图检查。
39例患者（23.4%）的ECG存在fQRS。SS II的中位数为27（22.9 - 33.9）。fQRS（+）组的SS II值在统计学上显著高于fQRS（-）组（35.2（26.4 - 47.2）对25.7（22.1 - 30.7），p < 0.001）。此外，在SS II较高的患者中，存在fQRS的ECG导联数量显著更多。
对于接受pPCI治疗的STEMI患者，ECG上fQRS的存在以及fQRS导联数量较多可能与高SS II相关。
