Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Pulmonary Hypertension (PH) is a disease that is characterized by vasoconstriction of small vessels of the lung. Many cases do have proliferation of endothelial cells within these vessels. A possible influence of polymorphisms of genes relevant for inflammatory and endothelial processes is suspected.

Especially patients with chronic heart failure can develope PH. The reasons therefore are lacking.

The researchers investigate different polymorphism and the influence of these on pulmonary artery pressure (measured invasively) in patients with congestive heart failure (CHF) and patients with primary pulmonary hypertension.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study consists of 3 arms-patients with CHF and PH, patients with CHF without PH and patients without CHF and PH.

The PH measurement is due to routine catheterization, thereafter we measure different vasoactive polymorphism.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CHF with elevated PAP

CHF patients (LVEF \> 35%) with elevated mean pulmonary pressure( \> 20 mmHg ) measured by pa catheter

No interventions assigned to this group

CHF patient without elevated PAP

CHF patients (LVEF \> 35%) with normal mean pulmonary pressure

No interventions assigned to this group

Normal EF with elevated PAP

Patients with normal LVEF \< 60% with elevated mean pulmonary pressure

No interventions assigned to this group
