Overview

The knowledge on the rare type of pulmonary hypertension which can not be explained by left heart disease, respiratory disease or congenital heart disease is very limited. Investigators aim to setup a national registration study for the rare type of pulmonary hypertension, to understand the natural history, survival, progression, genetic and environmental contributions to disease.

Detailed description

The main research contents of this registration study includes:

1. Build a baseline database of the rare type of pulmonary hypertension. Collect general information, on-set symptoms and time, laboratory examination, imaging results, right heart catheterization and treatment information. 2. Follow up recruited patients at regular intervals(6m\~1y). Collect information on change in patients condition, laboratory test and treatment. 3. Conduct genetic testing for gene mutation related or hereditary pulmonary hypertension. Link the clinical database to genetic database. 4. Establish bio-bank for serum/plasma, urine, stool, tissues or cells. 5. Establish prognostic study based on the clinical follow-up and genetic database. 6. Draw diagnostic and treatment algorithm for the rare type of pulmonary hypertension.

Controls subjects: blood sample and medical data collected once.

Interventions

  • Other laboratory biomarker analysis
    Laboratory results will be analysed to identify disease related biomarkers.
  • Genetic Genetic analysis
    Gene sequencing results will be analysed to identify disease related mutations.

Primary outcome measures

  • Survival Rate of Participants [Time frame: up to 10 years, at 12 months interval]
  • Lung transplantation [Time frame: up to 10 years, at 12 months interval]
  • Change in New York Heart Association (NYHA) functional class [Time frame: up to 10 years, at 3 months interval]
  • Change in 6 mint walk distance [Time frame: up to 10 years, at 3 months interval]
Secondary outcome measures (7)
  • Genetic alteration in participants with rare type of PH [Time frame: Baseline]
  • Change in NT-proBNP [Time frame: up to 10 years, at 3 months interval]
  • Change in hemodynamics [Time frame: up to 10 years, at 6 months interval]
  • Change in cardiac function [Time frame: up to 10 years, at 3-6 months interval]
  • Pulmonary endarterectomy (PEA) [Time frame: up to 10 years, at 6 months interval]
  • Balloon pulmonary angioplasty (BPA) [Time frame: up to 10 years, at 6 months interval]
  • Medical treatment [Time frame: up to 10 years, at 6 months interval]
