冠状动脉慢性完全闭塞病变患者碎裂QRS波与疾病严重程度及预后的关系

Relationship between f QRS and disease severity and prognosis in patients with chronic total coronary artery occlusion

目的分析冠状动脉慢性完全闭塞病变患者碎裂QRS波(f QRS)与疾病严重程度及预后的关系。方法选择2012年11月至2017年11月我院接收的76例冠状动脉慢性完全闭塞病变患者为研究对象,均采用血运重建术进行治疗,分析不同严重程度患者f QRS出现情况及治疗效果。结果 3支冠状动脉病变患者f QRS出现率明显高于1~<3支冠状动脉病变患者(P<0.05)。≥2 cm冠状动脉完全闭塞患者f QRS出现率明显高于<2 cm短段冠状动脉病变患者(P<0.05)。有f QRS患者临床治疗总有效率明显低于无f QRS患者(P<0.05)。结论 f QRS可反映冠状动脉慢性完全闭塞病变严重程度,有f QRS的冠状动脉慢性完全闭塞病变患者经血运重建术治疗预后情况较差。

Objective To analyze the relationship between fragmented QRS(f QRS) and disease severity and prognosis in patients with chronic total coronary artery occlusion. Methods From November 2012 to November 2017, 76 patients with chronic total coronary artery occlusion received by our hospital were selected as the study objects, all of the patients were treated with revascularization. The occurrence of f QRS in patients with different severity and therapeutic effect were analyzed. Results The incidence of f QRS in patients with three coronary artery lesions was significantly higher than that in patients with 1-<3 coronary artery lesions(P<0.05). The incidence of f QRS in patients with coronary artery lesions ≥2 cm was significantly higher than that in patients with short segment coronary artery lesions <2 cm(P<0.05). The total effective rate of clinical treatment in patients with f QRS was significantly lower than that in patients without f QRS(P <0.05).Conclusion f QRS can reflect the severity of chronic total coronary artery occlusion. Chronic total coronary artery occlusion patients with f QRS have poor prognosis after revascularization.
