Non-invasive Hemodynamic Assessment in Patients with Pulmonary Hypertension

Vascular remodelling of small vessels of the pulmonary circulation and consecutive right heart failure are the key features in the pathophysiology of pulmonary hypertension (PH). Until today invasive measurement of hemodynamics is indispensable for diagnosis and follow-up of this devasting disease. Aim of the study was to evaluate security, reproducibility and feasibility of a new non-invasive hemodynamic method in patients with PH. An inert gas rebreathing technique (Innocor®) was investigated in 30 patients (mean-age 65±12, m:f 10:20) with PH. Non-invasive hemodynamic assessment and invasive right heart cathet…
