Assessment of quality of life and its influence factors in patients with atrial fibrillation 3 months after catheter ablation / 中国介入心脏病学杂志

ABSTRACT

Objective To investigate the quality of life and its influence factors in patients with atrial fibrillation 3 months after catheter ablation. Methods From April 2014 to February 2016,AF patients who underwent single catheter ablation in our hospital were included. The quality of life was assessed by MOS 36 item short form health survey (SF-36), and the effect of related factors on QOL scores were further analyzed. Results There were no significant changes in quality of life at baseline and 3 months after catheter ablation including physical component summary (PCS) [(70.6±17.1) vs.(72.9±10.7),P =0.078]score, mental component summary (MCS) [(70.9±12.3) vs.(71.8±12.5), P =0.44] score and SF-36 score [(70.8±13.0) vs. (72.3±10.3), P=0.138]. Multivariate analysis indicated that there was negative correlation between patients who relapsed after ablation and better quality of life(PCS, β=―3.162, P=0.036;MCS, β=―5.675, P =0.001; total SF-36 score, β=―4.385, P =0.003), MCS score and warfarin use (MCS,β=―4.020,P =0.014). There was negative correlation between PCS score and smoking(PCS, β=―3.129,P =0.037).Conclusion All patients had stable quality of life in 3 months after catheter ablation. Ablation outcome was probably the main influencing factors. The use of dabigatran and smoking might also have effects on their quality of life.
