Overview
The Euro-CRAFT Registry is a prospective, multicentric, international registry of patients undergoing functional assessment of the coronary microcirculation using the continuous thermodilution technique. Angina and quality of life questionnaires (Seattle Angina Questionnaire 19 - SAQ19, ORBITA app) will be obtained at baseline, at 6 months, and 1-year follow-up. Clinical follow-up will be performed at 1 year (optionally until 5 years).
