摘要

本研究探討急性心肌梗塞患者發病後一個月內之身體活動量及其相關因素，以供日後設計心肌梗塞病患急性期復健運動的參考。以北部某醫學中心急性心肌梗塞後無併發症之病患爲對象，使用Bouchard身體活動量量表測量心肌梗塞後第三天、五天、七天、十四天、及一個月時之身體活動量。結果顯示本研究之個案發病前活動量平均爲39.2±2.8 kcal/kg/day (1.55+0.11MET)，梗塞後活動量以第三天爲最低，之後逐漸回升至一個月時相近於梗塞前之身體活動量。發病初期左心射出量爲身體活動之主要預測因子；第七天起，前一時間點之身體活動量爲主要預測因子。未來研究可進一步探討合適於急性心肌梗塞病患的介入性運動，以促進急性心肌梗塞病患體能的恢復與提昇。

Factors associated with patients physical activity levels in the month following acute myocardial infarction (AMI) were investigated for reference in designing rehabilitation programs for acute stage AMI patients. In a Taipei medical center, patients who suffered AMI without complications were selected for evaluation of physical activity levels on the 3rd, 5th, 7th, 14th, and 30th days following AMI, using Bouchard's Physical Activity Log. The results of this study reveal that 39.2±2.8 kcal/kg/day (1.55±0.11MET) was the mean physical activity level of patients prior to AMI. Activity was lowest on the 3rd day following infarction, and gradually rose again in one month to the activity level prior to infarction. In the early phase of AMI, the left ventricular ejection fraction (LVEF) was the dominant predictor of physical activity levels (explaining variance of 17~30%). Starting from the 7th day after AMI, the most recently measured activity level became the dominant predictor of physical activity levels. Further research on appropriate exercise interventions for restoring physical ability and promoting recovery of AMI patients is recommended.
