[[alternative]]The physical activity levels and quality of life in patient after acute myocardial infarction

[[abstract]]本研究目的為了解急性心肌梗塞病患身體活動量與生活品質的關係以及其影響因素，並探討身體活動量、日常活動主觀費力感及生活品質三者間的相關性。研究設計屬量性、描述相關性研究，以立意取樣（purposive sampling），選取台北某醫學中心之急性心肌梗塞病患為研究對象，由研究者協助病患於住院期間回憶梗塞前之身體活動量及填寫梗塞後第三天、第五天、第七天之身體活動量紀錄表，記錄病患身體活動情形，出院返家後以電話訪談方式收集病患資料，包括：梗塞後第二週及一個月之身體活動量、日常活動量表（Duke Activity Status Index，DASI）及生活品質量表（Quality of life after Myocardial Infarction，QLMI），以了解病患之身體活動量、日常活動主觀費力程度及生活品質。所得資料採SPSS 10.0 套裝軟體進行資料整理及建檔，並以描述性統計和獨立T檢定、One —Way ANOVA、Chi-square、皮爾森積差相關和逐步複迴歸等推論性統計方式進行資料描述與分析。研究結果發現，梗塞所測量之身體活動量，以梗塞後第三天為最低，平均活動量為29.7±1.7 kcal/kg/day，至梗塞後一個月之身體活動量已相近於梗塞前之身體活動量。梗塞後身體活動量受性別、身體質量指數、婚姻狀況、居住狀況及LVEF數值影響；梗塞後個案對活動主觀費力程度受性別、婚姻狀況及LVEF之影響；梗塞後病患生活品質，受性別、身體質量指數、婚姻狀況、居住狀況、教育程度及LVEF數值影響。綜合其身體活動量、日常活動主觀費力程度與生活品質的結果，彼此間相關；同時經逐步複迴歸分析得知，LVEE數值對梗塞後第七日之身體活動量具預測力，其可解釋之變異量達51﹪；而身體活動量影響生活品質，梗塞後第七日之身體活動量，可解釋梗塞後一個月生活品質之變異量達40﹪；日常活動主觀費力程度影響身體活動量，彼此呈負相關；生活品質則受身體活動量及日常活動主觀費力程度的影響。本研究結果有助於了解急性心肌梗塞病患身體活動量與生活品質的相關性，並可作為未來研擬介入措施之參考依據。[[abstract]]This study explored the connections of “physical activity levels” and “quality of life” in patients who just underwent acute myocardial infarction (AMI) attack. It was description - correlation designed. 25cases came from a medical center at Taipei by purposive sampling. Researcher recorded the clients’ physical activity levels at the 3rd, 5th, and the 7thday after their AMI attack.By telephone or e-mail,questionnaires of “Duke Activity Status Index(DASI)”and“Quality of Life after Myocardial Infarction (QLMI)” were performed when clients had suffered from AMI for 14 days and 30 days respectively in order to follow up their progressing of physical activity levels at home. Those data were then processed through SPSS v.10.0 for Windows . The major statistical procedures applied were descriptive statistics, independent —T test , one way ANOVA, Chi-square, Pearson correlation and Stepwise multiple regression .A probability level of p value less than 0.05 in assessed as statistically meaningful. The results indicated that the lowest physical activity in an average of 29.7 ±1.7 kcal/kg/day appeared at the 3rd day after AMI attack, and there were not obviously differences of physical activity between after 1 month and before AMI attack. It also revealed that the physical activity levels after AMI attack were relative to sexes, body mass index（BMI）, marriage, living status, and left ventricular ejection fraction (LVEF). The relationships between sexes, marriage, LVEF and subjective feelings of labor were notable. And, the quality of life after AMI attack connected to sexes, BMI, marriage, living status, education and LVEF. Overall the quality of life, physical activity and subjective feelings of labor were notable there are relative. Physical activity levels negative related to patients’ subjective feelings of labor; Quality of life connected to physical activity levels and subjective feelings of labor. The result of Stepwise multiple regression revealed that the major predictors of physical activity level at 7th day after their AMI attack were :LVEF，and the R square is 51﹪，the major predictors of quality of life were: physical activity level at 7th day after their AMI attack，and the R square is 40﹪. To understand the associations and relationships between AMI patients’ quality of life and physical activity levels is very important. It might be an additional intervention or exercise training of AMI in the future. This study will be helpful
