| 中文摘要:目的 探讨ST段抬高型心肌梗死患者碎裂QRS(fQRS)波与经皮冠状动脉介入治疗(PCI)后ST段回落不良的关系。方法 选取确诊为ST段抬高型心肌梗死并且住院行PCI术治疗的患者300例。将300例患者分为两组,即fQRS组(197例)和无fQRS组(103例)。分析患者的相关资料。结果 无fQRS组患者肌钙蛋白(cTnI)、肌酸激酶水平低于fQRS组,左心室射血分数高于fQRS组,差异有统计学意义(P<0.05)。fQRS组的术前、术后QRS时限数值与无fQRS组相比显著增大,差异有统计学意义(P<0.05)。fQRS组术前、术后ST段回落率显著小于无fQRS组,差异有统计学意义(P<0.05)。Logistic回归分析表明,与PCI术后ST段回落不良独立相关的因素有QRS时限增量、术前碎裂QRS波。结论 存在fQRS的STEMI患者PCI术后ST段回落情况不理想,心肌血供不良,冠脉闭塞较重,心肌梗死范围较大。 |

| Abstract:Objective To explore the association between fragmented QRS complexes(fQRS) and imperfect ST-segment resolution in patients with ST-elevation myocardial infarction(STEMI) after percutaneous coronary intervention(PCI). Methods This study included 300 patients with STEMI who underwent PCI. They were divided into two groups, fQRS(n=197) and without fQRS(n=103).The relative information was compared between the two groups. Results Patients with fQRS had higher cTnI, CK and lower left ventricular ejection fraction(LVEF) than that in patients without fQRS(P<0.05). Patients with fQRS had higher prolonged QRS interval and lower rate of ST-segment resolution than that in patients without fQRS(P<0.05). Logistic regression analysis demonstrated that the increased QRS interval and presence of fQRS before PCI were independent predictors of imperfect ST-segment resolution. Conclusion Fragmented QRS complexes is related to imperfect ST-segment resolution in STEMI patients undergoing PCI. Fragmented QRS complexes may be a useful parameter to identify the patients with coronary lesion, severe myocardial infarction and larger areas of ischemic injury. |
