Quality of life questionnaire
Qol was assessed using the questionnaire EQ-5D.The questionnaire was developed by the EuroQol group [14] to measure health outcomes and includes five dimensions: mobility, self-care, usual activities, pain/ discomfort and anxiety/depression. For each of the five dimensions, there are three levels of answers: no problems, some problems, extreme problems. In relation to the dimension Anxietyldepression, patients were instructed to assess their level of anxiety with regard to regular daily life and not specifically relating to the coronary angiography procedure. For assessing the patient's total health status, the questionnaire also includes a vertical scale (EQ-VAS), with the end-points best imaginable health state and worst imaginable health state. The patients marked the number on the scale that best agreed with their perceived overall health status.
