Marc Simon, MD, MS

Professor in Residence

Cardiology, Cardiology UCSF Health

CLINICAL INTERESTS: Dr. Simon is director of Pulmonary Vascular Disease and the Pulmonary Hypertension Comprehensive Care Center. He has expertise as a cardiologist specializing in pulmonary hypertension, advanced heart failure, and heart transplantation.

RESEARCH INTERESTS: Dr. Simon’s research primary research focus involves developing new therapies for pulmonary hypertension and better understanding right-sided heart failure in pulmonary hypertension (PH). Notably, right-sided heart failure and PH are associated with poor outcomes and in particular have been noted to occur in another type of heart failure, called heart failure with preserved ejection fraction or HFpEF, in which the heart seems to function normally but causes difficulty breathing due to a stiffening of the heart and blood vessels.
