【摘要】：目的:评估室性期前收缩(室早)导管消融术后早期左室射血分数(LVEF)恢复状况对室早心肌病患者远期左室收缩功能恢复的预测价值。方法:对诊断符合室早心肌病的42例患者进行为期1年的随访,分别在导管消融术前,导管消融术后3个月、6个月、12个月时行超声心动图检查以确定LVEF、左室舒张末期内径(LVEDD)。根据1周时LVEF是否改善(LVEF较基线水平增加≥25%)分为LVEF早期改善组和LVEF早期未改善组,比较2组患者在导管消融术前,术后随访第3、6、12个月时LVEF、LVEDD的差异。结果:与LVEF早期未改善组患者相比,LVEF早期改善组患者随访第12个月时有着更高的LVEF[(59.24±2.67)%∶(52.24±3.83)%,P0.05]。结论:室早导管消融术后早期LVEF恢复预示着室早心肌病左室收缩功能的完全恢复。
[Abstract]:Objective: to evaluate the predictive value of early left ventricular ejection fraction (LVEF) recovery in patients with ventricular premature cardiomyopathy. Methods: 42 patients with ventricular premature cardiomyopathy were followed up for 1 year. Echocardiography was performed before catheter ablation, 3 months, 6 months and 12 months after catheter ablation to determine LVEF and left ventricular end-diastolic diameter (LVEDDD). According to whether the improvement of LVEF was more than 25% of baseline level at 1 week, the patients were divided into two groups: early improvement of LVEF group and early improvement of LVEF group. The difference of LVEF and LVEDD was compared between the two groups before catheter ablation, 6 times after operation and 12 months after operation. Results: there was a higher LVEF (59.24 卤2.67% 52.24 卤3.83%) in the early improvement group than that in the early stage group (P 0.05). Conclusion: the early recovery of LVEF after ventricular premature catheter ablation indicates the complete recovery of left ventricular systolic function in patients with ventricular premature cardiomyopathy.
