Dipanjan Banerjee, MD, MS

Dipanjan Banerjee, MD, MS

Advanced Heart Failure and Cardiac Transplantation
Medical Director, Left Ventricular Assist Device Program

As one of the inaugural diplomates in Advanced Heart Failure/Transplant Cardiology, Dr. Banerjee cares for patients across the entire spectrum of heart failure. He plays a primary role in the left ventricular assist device (LVAD) program at Stanford, and also heads the heart failure quality improvement program.

Since graduating from college on the east coast, where he earned an AB in English, magna cum laude, at Harvard University, Dr. Banerjee has been moving steadily westward. He earned his MD, summa cum laude, from the University of Missouri-Columbia, and proceeded to Stanford for residency and fellowship training. During his fellowship, he obtained a masters degree in epidemiology, served as chief fellow, and pursued advanced training in heart failure/transplant, echocardiography, and preventive cardiology.

Dr. Banerjee's current research interests include investigating the relationship between insulin resistance and heart failure, exploring racial/ethnic disparities in cardiovascular disease, and implementing protocols to improve heart failure outcomes.

Michael B. Fowler, MB

Dr. Fowler serves as a professor of medicine at Stanford's School of Medicine. He is also director of the heart failure program, and medical director of the Cardiomyopathy Center in the Division of Cardiovascular Medicine at the School of Medicine.

Dr. Fowler completed his medical degree at the Charing Cross Medical School in London, in 1975. In 1982, Dr. Fowler became British/American reciprocal research fellow of the British Heart Foundation and the American Heart Association at Stanford University School of Medicine. Dr. Fowler was made a clinical assistant professor of medicine in cardiology and co-director of the cardiac advanced therapies clinic at Stanford Medicine in 1984.

In 1986 he was named co-director of the Coronary Care Unit and assistant professor of medicine in the Division of Cardiovascular Medicine. Dr. Fowler then served as the co-director of the heart failure clinic and as an associate professor of medicine before being appointed director of the heart failure program and medical director of the cardiomyopathy center, positions he continues to hold.

Dr. Fowler is also an active member of many societies, programs and committees, and serves on the editorial boards of several medical journals, including Congestive Heart Failure and the Journal of Clinical and Basic Cardiology. Dr. Fowler is a guest editor for the American Journal of Cardiology Supplement and other publications, and he serves on the scientific advisory board of the European Society of Cardiology. He has authored over 100 articles in peer-reviewed journals as well as several book chapters.

John S. Schroeder, MD

John S. Schroeder, MD

Dr. Schroeder is a professor of cardiovascular medicine at Stanford University School of Medicine. He has had a long career in the prevention, diagnosis, and treatment of congestive heart failure.

Dr. Schroeder was a member of the pioneering heart transplant team which performed the first transplant in the United States. He pioneered guidelines and treatment for heart transplant candidates and documented performance of the transplanted heart.

More recently, he has focused on the newer medical treatments for patients with congestive heart failure which has restored many very ill patients to essentially normal lives and therefore avoided heart transplant. His clinical research in heart transplantation has included methods to avoid recurrence of disease in the newly transplanted heart.

In recent years, Dr. Schroeder has focused on the identification of patients at risk for heart failure and its prevention through aggressive therapy of such common cardiovascular problems as hypertension, hyperlipidemia, coronary artery disease, and diabetes. In this regard, he has published several cookbooks aimed at a heart healthy diet including "The Stanford University Healthy Heart Cookbook & Life Plan."

He is a member of the American Heart Association, American College of Cardiology, and has served on many positions in these organizations as well as at Stanford Medical Center. He is a published author of 11 books and his bibliography reflects over 286 published scientific papers in national scientific medical journals.

Dr. Schroeder is a popular national and international speaker to physicians as well as patients. He is dedicated to cardiovascular health and optimal life function for all persons through healthy lifestyles and medical therapies.

Randall H. Vagelos, MD

Randall H. Vagelos, MD

Dr. Vagelos is a member of Stanford's heart transplant team, as well as the interventional cardiology group. He is an associate professor of medicine, and is the medical director of the cardiac care unit of Stanford Hospital & Clinics.

He completed his medical degree and internal medicine residency training at Columbia College of Physicians and Surgeons in New York. Dr. Vagelos then continued his postgraduate cardiology training at Stanford University School of Medicine, as well as fellowships in heart failure research and interventional cardiology.

Dr. Vagelos serves as chairman of the Quality Assurance Committee, for cardiovascular medicine, as well as chairman of the Hospital CPR Committee. Dr. Vagelos is also a member of the Medical Housestaff Committee for Residency Training and Clinical Service.

Currently, Dr. Vagelos serves as secretary and co-founding member of the Northern California Heart Failure Society. His clinical interests include studies of prognosis and novel therapies in congestive heart failure, as well as the chronic long-term cardiothoracic toxicities of radiation therapy.

Ronald M. Witteles, MD

Ronald M. Witteles, MD

Dr. Witteles earned his medical degree with honors from the University of Chicago Pritzker School of Medicine. He completed internship and residency in internal medicine at Stanford University, where he served as chief medical resident. He subsequently completed his cardiology fellowship training at Stanford, also serving as chief fellow. He is currently a member of the cardiology faculty at Stanford University, appointed as assistant professor of medicine and associate director of the Cardiac Intensive Care Unit (CCU). His specialty within cardiology is in the evaluation and treatment of patients with heart failure, and he serves as co-director of the Stanford Amyloid Center.

Dr. Witteles runs an active research program, leading and participating in multiple clinical trials. His research involves investigations of insulin resistance (prediabetes) in heart failure, cardiac effects of cancer therapies, interactions between heart failure and kidney disease, and treatment options for patients with cardiac amyloidosis.

Dr. Witteles has won many awards for his clinical care and research work. His research studies have twice been cited by the Journal of the American College of Cardiology as being among the most important publications of the year, and he has won research awards from the Heart Failure Society of America and the American College of Physicians. He is a 3-time winner of the Stanford University Franklin G. Ebaugh, Jr. award for Research and of the Cardiovascular Medicine Division award for clinical research.
