老年心动过速性心肌病患者临床特点分析

Analysis of clinical characteristics of elderly patients with tachycardiomyopathy

目的 探讨有心动过速性心肌病 (TCM)的老年患者的临床特点。方法 将合并快速心律失常并行经导管射频消融术 (RFCA)治疗的老年患者共 2 0 5例按有无TCM分为 2组 ,两组患者于术前常规行超声心动图及动态心电图检查 ,并于术后随访。所有患者记录心动过速的三个临床特征指标 ,分别研究其临床特点及其行RFCA后的疗效。结果 合并心动过速的老年患者左心室舒张末期内径的改变与心动过速病程及心动过速发作频率呈显著正相关 ,且两组间三个心动过速特征指标差异有显著性意义。老年TCM患者经成功消融根治快速心律失常后 ,左心室舒张末期内径及左心室射血分数均显著改善 ,阵发性心房颤动的发生率显著减少。结论 心动过速病程及心动过速发作频率是老年人发生TCM的危险因素 。

Objective To investigate the clinical characteristics of elderly patients with tachycardiomyopathy (TCM).Methods 205 elderly patients with tachycardia and undergoing radiofrequency catheter ablation(RFCA) were divided into two groups according to whether with TCM or not. UCG and Holter examination were performed in all patients routinely before and after RFCA. The values of three clinical features of tachycardia were recorded, and the clinical features and therapeutic efficacy after RFCA were studied.Results The changes of LVEDd in the elderly patients with tachycardia were positively correlated with duration and frequency of tachycardia significantly, and there was significant difference in values of three clinical features between two groups. After RFCA was performed successfully, the values of LVEDd and LVEF were improved significantly and the incidence of PAF was reduced significantly.Conclusions The duration and frequency of tachycardia are risk factors in elderly patients suffering from TCM. RFCA is an effective method to improve the cardiac function and to control the incidence of PAF for these patients.
