Pulmonary hypertension (PH) represents a spectrum of diseases that share the common finding of high blood pressure in the lungs. Although PH can result from a variety of causes, our clinical and research efforts are focused on PH that results from chronic lung diseases such as chronic obstructive pulmonary disease (COPD), emphysema, and interstitial lung disease.
The treatment of PH due to chronic lung diseases remains poorly understood, and yet it is one of the largest PH populations around. In conjunction with the existing National Jewish Health programs of excellence in respiratory medicine, the National Jewish Health Pulmonary Hyertension Center is committed to advancing the understanding and treatment of chronic lung disease PH.
“The National Jewish Health PH Center is uniquely positioned to take on the complex lung disease patient with PH. We take pride in our care of this important and challenging form of PH.” - Brett Fenster, MD
A Multidisciplinary Approach to PH
Our PH specialists are experts in cardiology, pulmonology, and rheumatology, and they collaborate to provide you optimal care. Our specialists work closely with the National Jewish Health Chronic Obstructive Lung Disease Program, Interstitial Lung Disease Program, Autoimmune Lung Disease Program, and Rheumatology Program to provide collaborative care for PH associated with these conditions.
A Pulmonary Physiology Laboratory
National Jewish Health has one of the world’s largest, state-of-the-art technology pulmonary physiology labs. We utilize cardiopulmonary exercise testing (CPET) to assess exercise performance in the evaluation of PH. CPET can help better differentiate chronic lung disease from PH. In addition, we perform CPET during cardiac catheterization for both clinical and research purposes.
A Cardiac Catheterization Laboratory
Cardiac catheterization is critical to the diagnosis and treatement of PH, and our facility offers the most current catheterization technology and techniques. In contrast to other PH programs, we perform both right and left heart catheterizations to fully assess the impact of left heart problems on PH. This allows for more appropriate use of PH pharmacologic treatments and adjunctive therapies. We utilize wrist catheterization to reduce recovery time and potential complications. Because we believe changes in pulmonary pressures during exercise may identify certain forms of PH, we also perform CPET during cardiac catheterization as part our research effort.
A Focus on the Right Heart
In contrast to many traditional cardiology programs that focus on the left heart, National Jewish Health Cardiology has significant expertise in right heart disease. Because the right heart plays a critical role in PH, we utilize state-of-the art right heart imaging using both echocardiography and cardiac magnetic resonance imaging. We use cardiac imaging and cardiac catheterization to help us treat the whole heart, not just the left or right heart.
Access to Research Protocols
We offer our PH patients access to clinical trials and research protocols, most of which focus on chronic lung disease PH. The National Jewish Health Pulmonary Hypertension Center has numerous ongoing and future studies that provide patients access to novel testing and treatments.
Have unexplained shortness of breath, chest pain, palpitations or edema (swelling)
Are at risk for PH because you have an autoimmune disease, heart failure or chronic lung disease
Results from your echocardiogram, lung function testing, or blood tests are suspicious for PH
