Maryl R. Johnson, MD, a native of Iowa, received her medical degree from the University of Iowa College of Medicine where she also completed postgraduate training in Internal Medicine and Cardiovascular Diseases. She joined the faculty at Iowa and was instrumental in the establishment of a cardiac transplant program, serving as the Medical Director of Cardiac Transplantation from 1984-1988. Her subsequent career has been entirely devoted to the care of patients with heart failure and following cardiac transplantation. She served as the Associate Medical Director of the Cardiac Transplant Program at Loyola University Medical Center from 1988-1994, Associate Medical Director of the Rush Heart Failure and Cardiac Transplant Program from 1994-1997, and Medical Director, Heart Failure and Transplantation at Northwestern Memorial Hospital from 1998-2002. She moved to the University of Wisconsin as Medical Director of Heart Failure and Transplantation and Professor of Medicine in July 2002. Dr. Johnson's clinical interests are in the care of patients with severe congestive heart failure, including the use of mechanical circulatory support devices and cardiac transplantation. She has a particular interest in the treatment and outcome of congestive heart failure in women. Her research interests include the use of mechanical assistance in patients with severe heart failure and the coronary artery disease which develops in cardiac transplant recipients. She has also been an investigator in many of the multicenter trials evaluating new agents for the medical treatment of heart failure.
Dr. Johnson served as a resident member of the Advisory Council of the National Heart, Lung, and Blood Institute and has been a member and chair of NIH review committees. She is an Associate Editor of the Journal of Heart and Lung Transplantation. She is the President-Elect of the American Society of Transplantation, has served as a member and Chair of the Heart Failure and Transplant Committee of the American College of Cardiology, and is currently Chair of the UNOS Thoracic Organ Transplantation Committee.
