Abstract: Objective To construct an Anticoagulation Therapy Database of Chinese Patients after Heart Valve Replacement in accordance with blood coagulation characteristics of Chinese patients, fill the gap of Chinese clinical research in valvular heart diseases, and provide a scientific and objective basic data and information exchange platform. Methods A national multicentre,prospective and cohort clinical research method was applied to establish an anticoagulation therapy database of Chinese patients after heart valve replacement, using the Internet as a platform. A case report form (CRF), which was in line with the actual situation of Chinese anticoagulation patients after heart valve surgery, was formulated through the discussion of experts from 36 cardiovascular surgery centers in China in the starting meeting of National Science amp; Technology Support Program during the Twelfth Five-year Plan Period.We planned to prospectively include patients receiving warfarin anticoagulation therapy and formal anticoagulation monitoring after heart valve replacement from January 1, 2011 to December 31, 2014. Database was constructed using warehousing technology, which allowed not only data monitoring, query and statistics, but also regular data backup and system updates. Results A network database entitled Anticoagulant Therapy Database of Chinese Patients after Heart Valve Replacement was constructed and linked with the homepage of Chinese Journal of Clinical Thoracic and Cardiovascular Surgery (http://www. zgxxwkzz. com), which constituted a national Internet information platform. From 1 January 2011 to 1 December 2012, 8 452 anticoagulation patients after heart valve replacement from 34 level-3A hospitals in China had been registered in the database. Further follow-up of these patients was being carried out in respective hospitals. Conclusion A large multi-center and open database and network information platform has been constructed. The database variables are in line with clinical characteristics of Chinese anticoagulation patients after heart valve replacement, which provide scientific and objective basic data and support for future clinical research and systemic analysis.
