当院外来心臓リハビリテーションの効果と今後の課題

Abstract

当院では2018 年1 月より外来集団心臓リハビリテーションを開始した．今回その効果を検討した．5 カ月間継続した患者14 名の初期・最終時の膝伸展筋力・6 分間歩行距離（ 6MWD ），嫌気性代謝閾値（ anaerobic threshold：AT ）時の酸素摂取量 （ VO2 ）等を比較した（ p<0.05 ）．結果，初期時と最終時の膝伸展筋力と6MWD に有意な改善が認められた．AT 時のVO2 に 変化がなかったことの一因として不十分な有酸素運動時間・頻度が挙げられる．今後，有酸素運動時間の延長や他職種の助力 による多角的な介入が必要であると考えられる．

In our hospital, ambulatory cardiac group rehabilitation began in January, 2018. This study investigated the effects of this rehabilitation program. The subjects were 14 patients who had participated in this program for five months. The knee-extension strength, six minutes walking distance, and VO2 at the anaerobic threshold were compared twice, using the results from the first and last assessments. The knee-extension strength and six minutes walking distance were significantly greater in the last assessment than the first assessment. There was no significant difference between the first assessment and the last assessment in the VO2 at the anaerobic threshold. Our results suggest that our rehabilitation program is not frequent enough nor does it provide enough aerobic exercise time. We need to extend the aerobic exercise time and make a unified multi-disciplinary multi-directional program.
