本研究目的主要探討台灣冠狀動脈手術後個案之生活品質的兩性差異。採橫斷性調查研究設計，以立意取樣方式，選取北部某醫學中心100位包括50位男性及50位女性冠狀動脈手術後之個案為研究對象。測量工具包含：採Short-Form 36評估生活品質及基本資料問卷收集角色功能與個案基本資料。採用之統計方法為Independentt及one way ANOVA。研究結果顯示，台灣男性與女性確實於冠狀動脈手術後之生活品質有顯著差異。在生活品質之整體生理健康構面平均得分男性為45.5，女性為40.1(p<.05)；在此構面內又以身體功能差異最顯著，男性為42.2，女性為37.9(p<.05)。於心理健康構面中之活力層面有顯著差異，男性之平均得分為49.6，女性為45.2(p<.05)。研究結果亦發現，扮演角色功能如照護老人或做家務越多者，其生活品質得分越高。

The purpose of this study was to investigate gender differences in quality of life for post Coronary Artery Bypass Grafting (CABG) patients in Taiwan. Cross-sectional survey research design and purposive sampling were used in this study, for which 100 subjects, including 50 males and 50 females, were recruited from a medical center in northern Taiwan. Quality of life was measured by Short Form 36, while gender role function and demographic data were collected using a demographic questionnaire. An Independent t test and one way ANOVA were employed to analyze data. Study results showed significant differences in quality of life between genders. There was a statistically significant difference in the physical component summary score, post-CABG, between males (M=45.5) and females (M=40.1, p＜.05), which indicates that men demonstrated higher physical functioning than women. Within this component, the greatest difference between the genders was noted in sub-items related to physical functions. Men and women achieved mean scores of 42.2 and 37.9, respectively (p＜.05). For the mental component summary section, sub-items related to vitality also demonstrated statistical significance; with men achieving a mean score of 49.6 and women a mean score of 45.2 (p＜.05). Of interest, post-CABG patients who had greater role responsibilities, such as taking care of elderly or doing housework, obtained significantly higher quality of life scores.
