Pulmonary Arterial Hypertension

Study performed at various medical centers to learn more about survival and expected course of Pulmonary Arterial Hypertension, a type of high blood pressure in the lungs related to the narrowing of the small blood vessels in the lungs

Trial purpose

In this study researchers want to learn more about Pulmonary Arterial Hypertension, a type of high blood pressure in the lungs related to the narrowing of the small blood vessels in the lungs (group 1 according to WHO classification). Goal of the study is to describe the signs and risk factors of the illness at study start and the chances of survival.
