About this study
Official title: Multi-marker Approach for Risk Assessment in Pulmonary Arterial Hypertension (PAH)
Prospective registry including incident patients and prevalent patients which pretends to identify clinical characteristics, treatment trends in-hospital and ten years follow-up outcome through major adverse cardiovascular events (MACE) in a China population with well characterized PAH.
Read the detailed description
baseline include: An echocardiogram to assess the size, shape, pumping action and the extent of any damage to the heart.
Lung function tests which include blowing measurements to assess gas volumes within the lungs as well as assessment of how the lungs exchange gases.
Right heart catheterisation (RHC) to diagnose PAH Optional Cardiac Magnetic Resonance tests. 6 minute walk distance (6MWD). To measure exercise capacity Electrocardiogram (ECG), a test that measures the electrical activity of the heart Blood tests
MACE include:
death heart/lung transplantation atrial septostomy hospitalization due to worsening of PAH start of new specific PAH treatment persistent decrease of >15% from baseline in 6MWD (or >30% compared with last study-related measurement) persistent worsening of World Health Organization (WHO) Functional Class (FC）

What is being measured
The primary outcome is the main question the study is designed to answer.

clinical worsening
one of the following: death, heart/lung transplantation, atrial septostomy, hospitalization due to worsening of PAH, start of new specific PAH treatment, persistent decrease of >15% from baseline in 6MWD (or >30% compared with last study-related measurement), persistent worsening of WHO FC
Measured: 5 years
