Brief Summary
-----------------
CHina Registry for the chAracteristics and Management strategieS of patiEnts With Pulmonary Hypertension Using Targeted Therapy (CHASE Study)

Detailed Description
-----------------
The purpose of this study was to establish the clinical characteristics and treatment strategies of targeted pulmonary hypertension patients in China: a multicenter, prospective case registry (CHASE) study to describe the clinical characteristics, treatment used, disease progression, and outcomes (e.g., death, hospitalization) of patients taking targeted drugs in real-world clinical practice. This study will collect high-quality real-world data that can be used as a standalone dataset or combined with other data sources to address critical issues in the PH field. This is a prospective, observational, multicenter study. The expected number of enrolled cases for the entire study: at least 5000; No experimental group and control group were divided. Patients were followed up every 6 months ±2 weeks after enrollment for 3 years. The study selected patients who signed informed consent, aged 18-25 years, clinically diagnosed with pulmonary hypertension, and were applying or planning to apply targeted drugs for pulmonary hypertension as the study objects. The primary endpoint was the incidence of clinical exacerbations at 1 year after enrollment. Secondary endpoints were all-cause mortality at 1, 2, and 3 years after enrollment, rate of lung transplantation or combined cardiopulmonary transplantation, 6-minute walking distance, NT-proBNP level, WHO cardiac function grade, ratio of right ventricular end-diastolic diameter to left ventricular end-diastolic diameter, pulmonary hypertension targeted drug regimen, and incidence of associated adverse reactions.
