Physical Activity, Physical Fitness, and Quality of Life after Coronary Artery Bypass Grafting

冠狀動脈繞道術後之身體活動、體適能與生活品質研究

摘要


Background and Purpose: Patients undergoing coronary artery bypass graft (CABG) have a high long-term survival rate. Therefore, it is an important health issue to improve the long-term physical fitness and quality of life (QOL) of this population. This study aimed (1) to compare the physical activity, physical fitness, and QOL in patients who received CABG surgery ≤ 4 years and > 4 years, and (2) to examine the factors related to the physical fitness and the QOL among these patients. Methods: Three hundred and eleven patients following CABG surgery (265 men and 46 women) participated in this study. Physical activity (PA) and QOL were assessed using the International Physical Activity Questionnaire (IPAQ) and the World Health Organization Quality of Life Instrument-Brief Version, respectively. Physical fitness measurements included grip strength, 30-second chair stand test, and 6-minute walking test (6MWT). Results: There were no significant difference in PA levels, physical fitness, and QOL between postoperative ≤ 4 years and > 4 years groups (p > 0.05). Compared to medium- and high-level PA groups, the low PA group had significantly lower performances in grip strength, 30-second chair stand test, and 6MWT, and scored lower in some QOL domains with adjusted covariates (p < 0.01). After multivariable adjustments, the β values for QOL in the physical health and the psychological domains of the high PA group in comparisons with the low PA group were 1.19 and 1.01 (p < 0.01), respectively. In addition, the β values decreased after controlling for 6MWT distances (p < 0.01). Conclusions: For patients underwent CABG with long duration, lower PA level was still the significant and important factor associated with lower physical fitness and QOL.

背景和目的:冠狀動脈繞道術後患者長期存活率已大幅提高,因此促進這些患者長期體適能與生活品質是相當重要的健康議題。本研究的目的包括:(1)比較冠狀動脈繞道術後4年內與4年以上患者之身體活動量、體適能與生活品質是否有差異;(2)分析影響這些患者體適能和生活品質的因素。方法:共有311位(265位男性和46位女性)參與本研究。我們分別採用國際身體活動量問卷(International Physical Activity Questionnaire)和世界衛生組織生活品質問卷-短版(World Health Organization Quality of Life Instrument-Brief Version)評估身體活動量和生活品質。體適能評估包括手握力、30秒椅子站立和6分鐘行走測驗。結果:冠狀動脈繞道術後4年內與4年以上患者之身體活動量、體適能與生活品質並無統計上顯著差異(p > 0.05)。與中、高身體活動量組比較,低身體活動組有顯著較低的手握力、30秒椅子站立次數、6分鐘行走距離和生活品質(p < 0.01)。經過校正共變數後,高身體活動量組患者的身體健康面向和心理面向顯著較低身體活動量組高,β值分別為1.19和1.01(p < 0.01)。此外,生活品質與身體活動量的關係主要受到6分鐘行走距離影響(p < 0.01)。結論:對於冠狀動脈繞道手術後的長期患者,低身體活動量仍是影響體適能和生活品質顯著且重要的因素。
