| 目的 探讨碎裂QRS波(fQRS)与急性冠状动脉综合征患者冠状动脉病变之间相关性。方法 收集急性冠状动脉综合征(ACS)患者204例临床资料,其中ST段抬高性心肌梗死(STEMI)75例和非ST段抬高性急性冠状动脉综合征(NST-ACS)129例,根据有无fQRS分为fQRS(+)和fQRS(-)两组,分析fQRS与冠状动脉病变相关性。结果 在fQRS(+)组中,ACS类型、病变血管数、Gensini评分、年龄、性别与fQRS(-)组之间的差异均有统计学意义(P<0.05)。logistic回归分析显示,fQRS波形成与高Gensini评分、三支病变、老年(>65岁)有关(OR=3.234,95%CI:1.386~7.543,P=0.007;OR=2.358,95%CI:1.114~4.992,P=0.025;OR=0.318,95%CI:0.150~0.672,P=0.003)。Spearman相关分析显示fQRS波导联数量与Gensini积分之间呈正相关(r=0.308,P=0.008)。结论 fQRS可作为评估冠状动脉病变范围、程度的一种无创指标。 |

| Objective To evaluate the relationship between the fragmented QRS(fQRS) complexes and the coronary artery lesions in patients with acute coronary syndrome(ACS).Methods A total of 204 patients with ACS, including 75 cases of ST-elevated myocardial infarction(STEMI) and 129 cases of non-ST-elevatedACS(NSTEACS), were retrospectively collected and evaluated in this study.All patients were divided into fQRS(+) group and fQRS(-) group, and the relationship between fQRS and coronary artery lesions were analyzed.Results In the fQRS(+) group, the ACS type, involved vessels, Gensini score, age and sex were of statistically significant differences when compared with those in the fQRS(-) group.Logistic regression analysis demonstrated that high Gensini score, three involved vessels and age >65 years were independent predictors of the presence of fQRS complexes(OR=3.234, 95%CI1.386-7.543, P=0.007;OR=2.358, 95%CI 1.114-4.992, P=0.025;OR=0.318, 95% CI 0.150-0.672, P=0.003, respectively).Spearman correlation analysis showed that the number of leads with fQRS complexes were positively related with the Gensini score(r=0.308, P=0.008).Conclusion The fQRS complexes could be used as a noninvasive indicator for evaluation of the range and severity of coronary artery lesions. |
