Outline of Final Research Achievements |
The present study was aimed to evaluate physical activities and motor function by using an accelerometer in patients who underwent catheter ablation for atrial fibrillation. After the follow-up period of 6 months, mean daily steps and maximum daily steps were increased from pre-ablation to post-ablation procedure. Moreover, the exercise intensity was increased after the ablation. The improvement of physical activities and motor function was found in the early phase after the ablation procedure. The results may be explained by the effect of suppressing atrial fibrillation and improvement of cardiac hemodynamics.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、心房細動アブレーション治療前後の運動機能や活動能力を、活動量計を用いて客観的に評価したものである。その成果として、活動量や運動能力の改善が、アブレーション術後比較的早期から改善していることが判明した。心房細動カテーテルアブレーション治療後では血管穿刺や自律神経への影響もあるが、運動機能と活動量への影響が早期に認められたことは、術後のADL向上や早期社会復帰への指標となりえることが考えられる。
