Do you have pulmonary hypertension? Researchers at National Jewish Health are studying the relationship between GDF-15 biomarker levels and your response to standard pulmonary hypertension treatment. If you are 18 years of age or older, have a diagnosis of pulmonary hypertension and you have never received treatment for pulmonary hypertension, then you may qualify! Study participation involves 2 blood draws over a six month period. Please call Valerie Snyder at 303.270.2591 for more information and to see if you qualify!
