Associate Clinical Professor

James Wilentz, MD is an Associate Clinical Professor at the Arnhold Institute of Global Health and the Department of Global Health and Health Systems Design. He has been an interventional and consultant cardiologist at Mount Sinai since 1993 and Associate Clinical Professor of Medicine.

In 2010 after the earthquake in Haiti, Dr. Wilentz began his journey into global health, volunteering with Partners in Health at the General Hospital in Port-au-Prince. There he saw, first-hand, mothers carrying their children in lines stretching a quarter mile around the hospital. They had come from all over Haiti after learning that there were foreign doctors willing to see their children without cost. From this experience, in 2010 Dr. Wilentz wrote an OpEd for the NY Times, “In Haiti, a Lesson for U.S. Health Care”  which dealt with lack of private / government coordination in healthcare – a concept we are still wrestling with. At the urging of Dr. Paul Farmer, Dr. Wilentz and Owen Robinson co-founded the NGO, Haiti Cardiac Alliance, facilitating life-saving surgery and interventional treatments for children and young adults with congenital and valvular heart disease. The Cardiac Alliance is in the process of branching out into Bolivia and the Dominican Republic.

At the Arnhold Institute, Dr. Wilentz has been mentoring MD and MD/MPH students in researching socio-economic and demographic barriers to access for specialty cardiac care in Haiti. Our team has completed its first paper, currently in review for publication. It is our hope to build on these projects and other ongoing Global Health department projects including the Mt. Sinai Guyana NCD project.

Dr. Wilentz’ publications have appeared in Circulation, Am Heart Journal, J Am Coll Cardiol and Lancet Global Health.
