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＜0.001)) and BNP levels were significantly lower (( 202.0 ± 23.2) pg／L vs (94±13.3) pg／L),(P＜0.001).For the unsuccessful subgroup,there was no significant change in E／e′values (16.3±6.3 vs 15.2±5.6) and BNP levels ((223.0±26.8) pg／L vs (245.0±23.9) pg／L), (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.
