Pulmonary Hypertension

The Pulmonary Division at Indiana University School of Medicine has several clinics in which patients with all types of pulmonary hypertension (WHO group 1-5) are actively evaluated and treated. All physicians are board-certified pulmonologists with special interest and expertise in pulmonary vascular disease and hemodynamic evaluation. We work closely with our colleagues in the Cardiology, Rheumatology and Gastroenterology/Hepatology Divisions as well as the Radiology and Thoracic Surgery Departments to provide the best possible interdisciplinary and patient-focused care. We offer education for patients, trainees, and physicians, close monitoring of potential treatment side effects, novel treatments and research protocols for eligible patients. All modern diagnostic modalities including cardiac MRI and cardiopulmonary exercise testing are available. Treatment modalities include oral drugs (bosentan, sildenafil, ambrisentan) as well as inhaled, subcutaneous and intravenous medications (prostacyclins and inhaled nitric oxide).
