    Abstract:
    OBJECTIVE: To evaluate quality of life (QOL) of patients with different severity of coronary artery disease using Seattle angina questionnaire (SAQ). METHODS: A total of 513 hospitalized patients undergoing coronary angiography from December 2007 to December 2008 were included. QOL of these patients was measured with SAQ and their demographic and clinical data were collected. Patients were divided into 3 groups according to the severity of coronary artery disease by coronary angiography. And comparisons of traditional risk factors and QOL were made among these groups. Multiple linear regression analysis was conducted to identify the variables associated with QOL. RESULTS: The scores of physical limitation were significantly different among 3 groups according to the severity of coronary artery disease by coronary angiography (80 +/- 16, 79 +/- 19 and 71 +/- 22, P < 0.01). Multiple linear regression analysis showed that physical limitation of the patients was affected by age (P < 0.01), gender (P < 0.01) and severity of coronary artery disease (P < 0.01). Angina stability was affected by the history of myocardial infarction (P = 0.03). Angina frequency was affected by the history of myocardial infarction (P = 0.01) and gender (P = 0.04). Treatment satisfaction was affected by the severity of coronary artery disease (P = 0.03) and disease perception by the history of DM (P = 0.03). CONCLUSION: Age, gender, history of myocardial infarction, history of DM and severity of coronary artery disease are independent predictors of QOL in patients with coronary artery disease.
