目的探讨心电图QRS时限与老年急性心肌梗死(AMI)患者预后的相关性。方法选取2014年1月至2015年1月河南省永城市中心医院收治的111例老年AMI患者作为研究对象,根据心电图QRS时限将其分为A组(心电图QRS时限≤110 ms,54例)和B组(心电图QRS时限>110 ms,57例)。比较两组患者的心功能、N-末端脑钠肽前体(NT-pro BNP)和左心室射血分数(LVEF)水平、并发症发生情况。结果 A组患者心功能Killip分级Ⅰ级构成比明显高于B组,Ⅱ级、Ⅲ级、Ⅳ级构成比明显低于B组,差异均有统计学意义(均P<0.05);A组患者的NT-pro BNP水平明显低于B组,LVEF水平明显高于B组,差异均有统计学意义(均P<0.05);A组心律失常、肺水肿、呼吸衰竭、心源性休克、心源性猝死的发生率均明显低于B组,差异均有统计学意义(均P<0.05)。结论心电图QRS时限与老年AMI患者预后密切相关,即心电图QRS时限延长则患者预后差,临床应重视心电图QRS时限对老年AMI患者预后的评估价值。
Objective To investigate the correlation between ECG QRS duration and the prognosis of elderly patients with acute myocardial infarction (AMI). Methods A total of 111 elderly patients with AMI who were admitted to Central Hospital of Yongcheng, Henan Province from January 2014 to January 2015 were enrolled in this study. Patients were divided into group A (ECG QRS ≤110 ms, 54 cases) and ECG Group B (ECG QRS duration> 110 ms, 57 cases). The cardiac function, N-terminal pro-brain natriuretic peptide (NT-pro BNP) and left ventricular ejection fraction (LVEF) were compared between two groups. The complication occurred. Results The Killip gradeⅠconcentration of heart function in group A was significantly higher than that of group B, and the constituent ratios of gradeⅡ, Ⅲ, Ⅳ were significantly lower than those in group B (all P <0.05). In group A (P <0.05). The level of NT-pro BNP in group A was significantly lower than that in group B, the level of LVEF was significantly higher in group B than in group B (all P <0.05); Group A had arrhythmia, pulmonary edema, respiratory failure, cardiogenic shock, The incidence of sudden death was significantly lower than the B group, the difference was statistically significant (P <0.05). Conclusion ECG QRS duration is closely related to the prognosis of elderly patients with AMI, that is, the extension of ECG QRS duration is poor prognosis, clinical ECG ECG should pay attention to the prognosis of elderly patients with AMI evaluation of the value.
