老年急性心肌梗塞患者Q-Tc间期延长的意义

The Singificance of the Prognosis of AMI Patients with Prolonged Q - TB Interval in elderly

目的探讨Q-Tc间期的延长对老年急性心肌梗塞(AMI)患者预后评估的意义。方法将78例老年急性心肌梗塞患者与56例无急性心肌梗塞的冠心病(CHD)患者作对照分析,并根据急性心肌梗塞患者是否发生室速、室颤或心脏猝死, 将其分为严重心律失常组和无严重心律失常组,观察Q-Tc间期。结果急性心肌梗塞组的Q-Tc值为0.47±0.04s,无心肌梗塞的冠心病组的Q-Tc值为0.42±0.03s,两组间差异显著(p<0.01)。严重心律失常组的Q-Tc间期和无严重心律失常组的Q-Tc间期分别为0.49±0.03s及0.46±0.04s,两组差异显著(p<0.01)。结论老年急性心肌梗塞患者合并Q-Tc间期延长者预后较差。

Objective To assess the prognosis of AMI (acute myocardial information) patientsby observing the prolonged time of Q - Tc intervai of elder patients Methods 78 AMI elder and 56 CHD patients without AMI were compared and analyzed. The AMI patients are divided into serious arrhythmia group and non - serious arrhythmia group, according to the occurrence of ventricular fibrillation , ventricular tachycardia and sudden cardiac death. Results The Q - Tc interval of AMI group and CHD group is 0.47±0.04s and 0.42 ±0.03s. The difference between the two group is significant (p < 0.01) The Q - Te interval of serious arrhythmin group and non - serious arrhythmia group is 0.49±0. 03s and 0. 46 ±0. 04s respectively. The difference is significant (p < 0. 01) Conclusion The prognosis of AMI patients with prolonged Q - Tc interval is dangerous in elderly.
