Abstract

Objective To observe whether catheter ablation for ventricular premature complexes (PVC) has an effect on ventricular diastolic function in elderly patients. Methods Elderly patients older than 65 years of age who underwent catheter ablation from March 2012 to May 2015 for idiopathic ventricular premature complexes were enrolled.Preoperative echocardiography was performed using E/e′ for left ventricular diastolic function and venous brain natriuretic peptide (BNP) levels were measured.All patients underwent catheter ablation under the guidance of a three-dimensional mapping system.Cardiac ultrasound and BNP levels were repeated 6 months after ablation, and 24-hour electrocardiogram was performed to confirm ventricular premature complexes. Results There were a total of 89 patients with idiopathic ventricular premature complexes (PVC) who underwent catheter ablation.81 cases were successed at 6 months, with a success rate of 91.0%.At 6 months after ablation, the E/e′ values were significantly lower ((15.3±5.2) vs (10.2±3.2), (P 0.05). Conclusion The number of premature ventricular beats is associated with left ventricular diastolic function, and ventricular premature catheter ablation can improve left ventricular diastolic function in elderly PVC patients.

室性导管过早消融对老年患者舒张功能的影响

目的观察导管消融术治疗室性早衰(PVC)对老年患者心室舒张功能的影响。方法选取2012年3月至2015年5月因特发性室性早衰并发症行导管消融治疗的年龄大于65岁的老年患者。术前行超声心动图E/ E '检查左室舒张功能，测定静脉脑钠肽(BNP)水平。所有患者均在三维绘图系统的指导下行导管消融。消融后6个月复查心脏超声和BNP水平，24小时心电图确认心室过早复合物。结果89例特发性室性早衰(PVC)患者行导管消融治疗。6个月成功81例，成功率91.0%。消融后6个月，E/ E值明显降低(15.3±5.2)vs(10.2±3.2)，P < 0.05。结论室性早搏次数与左室舒张功能有关，室性早搏导管消融可改善老年室性早搏患者左室舒张功能。关键词:心室过早复合物;导管消融;舒张功能;脑利钠肽;老年人
