心肌梗塞（MI）後的復健重點在於「循序漸進（Gradual progression）」。初期心臟受損，心肌修復需要時間，過度活動會增加心臟負荷。步行是最適合的復健活動，能有效改善心肺耐力，且風險可控。護理師應指導病人從輕度、短時間的步行開始，根據心率（Heart rate）與自覺疲勞程度（Borg scale）逐步增加強度，並強調若出現胸痛應立即停止。
Cardiac rehabilitation emphasizes gradual progression to avoid excessive strain on the healing myocardium. Light aerobic activities like walking are recommended initially, with intensity increased based on heart rate and perceived exertion, while high-intensity exercises are reserved for later stages.
