The China Pulmonary Thromboembolism Registry Study

Epidemiological data on pulmonary embolism (PE) in China needs to be updated and reported. The China Pulmonary Thromboembolism Registry Study (CURES) is designed to provide the cross-sectional spectrum and chronological trends of PE in China, as well as to reveal the intrinsic etiology and pathogenesis of the disease. The CURES is an ongoing large prospective multicenter registry, which was originally initiated in January 2009 via enrolling suspected or confirmed PE or PE with DVT (deep venous thrombosis) patients and assessed their in-hospital outcomes from 100 medical centers in the China PE-DVT network. As of July 2011, in order to determine the PE-relevant short-term outcomes, enrolled participants were followed-up for at least three months in a longitudinal manner. Since August 2016, with the launch and development of precision medicine research scheme in China, the main principle investigators of CURES decided to collect enrolled patients' blood samples with regular follow-ups every three or six months for at least two years (for long-term outcomes). The study protocol has been approved by the China-Japan Friendship Hospital ethics committee, and all collaborating centers received approvals from their local ethics committee. All patients provided written or verbal informed consent to their participation.
