Condition: Pulmonary Hypertension · Pulmonary Thromboembolisms · Sponsor: University of Sao Paulo General Hospital
Pulmonary hypertension is a serious and progressive disease that is difficult to treat and diagnose, mainly because its symptoms are nonspecific and often delay recognition. Early diagnosis is a major challenge. Although several tests may suggest the disease, the definitive diagnosis still requires right heart catheterization, an invasive procedure that directly measures pulmonary hemodynamics such as pulmonary artery pressure, cardiac output, and vascular resistance. Electrical impedance tomography (EIT) is a non-invasive, radiation-free bedside monitoring method that can evaluate ventilation and pulmonary perfusion. The number of studies investigating perfusion with EIT has been increasing, since the possibility of having a safe, radiation-free, and repeatable method available at the bedside is of great clinical interest in different fields of medicine. Our hypothesis is that EIT provides information that correlates with the findings of right heart catheterization in patients with suspected pulmonary arterial hypertension (PAH). EIT may serve as a useful screening tool prior to catheterization and may also help in risk stratification of patients with pulmonary hypertension
