Study Design of the Japanese Association of Cardiac Rehabilitation Registry (J-CARRY) - Protocol for a Prospective, Multicenter, Open Registry.

Guidelines for the prevention and management of cardiovascular disease (CVD) highly recommend cardiac rehabilitation (CR) on the basis of abundant evidence of its effectiveness. However, the current understanding and dissemination of CR in Japan are far from sufficient. The Japanese Association of Cardiac Rehabilitation Registry (J-CARRY) is an academic society-led prospective multicenter observational registry conducted by the Registration and Facility Accreditation System Committee of the Japanese Association of Cardiac Rehabilitation. Data are collected prospectively using an electronic data capture system. Items related to patients' clinical background and CR, as well as mortality and major adverse cardiac and cerebrovascular events, will be collected in all cases. This Registry started in May 2014, and the number of participating medical institutions is expected to increase to >30; the targeted number of cases exceeded 3,000 per year as of April 30, 2022. Focusing on late Phase II data collection is a novel and significantly different approach compared with previous studies. The results of this study are currently under investigation. J-CARRY will provide real-world data regarding the current status and prognosis of CVD in patients who undergo Phase II CR in Japan.
