まとめ
ライフスタイルの歩行による介入は,心不全患者の毎日の歩みを増加させたが,機能能力は改善しなかった. 心不全の機能的結果と身体活動の増加を関連付けるためのさらなる研究が必要である.
科学分野:
- 心臓病科
- 回復医療
- 公衆衛生
背景:
- 運動,特に歩行は,心不全の低射出率 (HFrEF) の管理に不可欠です.
- HFrEF患者にとって 歩行を日常生活に組み込むことは 実践的なアプローチです
- ライフスタイルの介入がHFrEFの機能能力に与える影響を評価することが不可欠です.
研究 の 目的:
- HFrEF患者の6ヶ月のライフスタイルウォーキング介入が機能能力を改善するかどうかを評価する.
- 通常のケアと比較して,6分歩行テスト (6MWT) に関する介入の効果を評価する.
- 身体活動レベルやバイオマーカーを含む二次結果への影響を調査する.
主な方法:
- HFrEF患者 (NYHAクラスII-III) を含む6ヶ月の多センターランダム化対照試験 (WATCHFUL試験)
- 介入グループは活動トラッカーを使用し,行動変化のための毎月の電話カウンセリングを受けました.
- 対照群は通常の治療を受け,主なアウトカムは6ヶ月で6MWTの距離でした.
主要な成果:
- 6ヶ月のグループ間の6MWT距離の有意な差はありません (平均差は7. 4メートル,P=0. 345).
- 介入グループは,平均日歩数 (+1420歩) と中等から激しい身体活動 (+8. 2分) が有意に増加した.
- 他の二次的アウトカムでは,グループ間の差異は認められなかった.
結論:
- ライフスタイルウォーキングによる介入は,HFrEF患者における身体活動の増加に成功したが,機能能力の改善には至らなかった.
- ステップの増加と機能改善の間の断絶はさらなる調査を正当化します.
- 将来の研究は,HFrEFにおける身体活動と機能的成果を結びつけるメカニズムを探求すべきである.
