| Seattle Angina Questionnaire,EQ5D questionnaire | 5 year | Quality of life score assessed by the EQ-5D-5L The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. Higher score of EQ-5D and EQ VAS means the low quality of life. EQ-5D: the minimum and maximum values are 5 and 25 respectively. EQ VAS: the minimum and maximum values are 0 and 100 respectively. Seattle Angina Questionnaire The Seattle Angina Questionnaire (SAQ) is a vali- dated disease-specific instrument for assessing the health status of patients with coronary artery disease. SAQ scores can be aligned with clinical constructs (eg, scores on the SAQ angina frequency scale of 0-30 points indicate daily angina, 31-60 points indicate weekly angina, 61-99 points indicate monthly angina, and 100 points indicate no angina) |
