【摘要】 目的:探讨心电图碎裂QRS波(fQRS)对急性冠脉综合征(ACS)患者死亡率的预测价值。方法:选择诊断为急性冠脉综合征入院的患者149例,其中MI组74例,其中非ST段抬高型心肌梗死组(NSTEMI)54例;不稳定性心绞痛(UA)75例(作为对照组),分析fQRS与死亡率的关系。结果:在MI组37例(50%)出现了fQRS波,而在对照组,只有3例(4%)(P<0.001),MI,NSTEMI,对照组出现病理性Q波分别为20例(27%),12例(22%),0例(0%)。Ka-plan-Meier生存分析揭示出现fQRS的患者比没有出现fQRS的病人死亡率更高。结论:ACS患者中出现fQRS的病人比未出现fQRS的患者死亡率更高。更多还原

【Abstract】 [Objective] To study the predictive value of fragmented QRS complex(fQRS)for mortality in acute coronary syndrome(ACS).[Method] Serial electrocardiograms from 149 patients with ACS who underwent cardiac catheterization were studied.149 cases of patients diagnosed with ACS were enrolled.74 patients had MIs,including 54 patients with non-ST-elevation myocardial infarction(NSTEMI),and 75 patients had UA(the control group).Relationship between fQRS and mortality was analyzed,as well as the relationship between the fQRS complex and the mortality.[Result] Fragmented QRS developed in 37 patients(50%) in the MI group and only 3(4%) in the control group(p <0.001).New Q waves developed in 20(27%),12(22%),and 0(0%) patients in the MI,NSTEMI,and control groups,respectively.Kaplan-Meier survival analysis revealed that patients with fQRS had significantly decreased death rate compared to those without fQRS.[Conclusion] Patients with fQRS of ACS had significantly decreased death rate compared to those without fQRS.更多还原
