China Pulmonary Vascular Disease Intervention Diagnosis and Management Study-right Heart Catheterization

This study is led by the China-Japan Friendship Hospital and will be conducted across approximately 30 pulmonary hypertension centers in China. It is an observational cohort study without interventional treatment. Eligible participants are patients aged 14 years or older who undergo right heart catheterization due to dyspnea or suspected pulmonary hypertension. After study initiation, investigators at each center will enroll eligible patients and collect baseline data, hemodynamic parameters from right heart catheterization, diagnostic classification of pulmonary hypertension, and treatment plans. Patients will receive routine follow-up at their respective centers, and investigators will gather follow-up data according to the study protocol. All de-identified data will be recorded in an Electronic Data Capture (EDC) system. A dedicated data management team will oversee data management, quality control, and statistical analysis.
