Our large multi-disciplinary team consists of twelve cardiologists specializing in the care of patients with advanced heart failure, cardiac transplant and mechanical circulatory support. This group is complemented by a nurse manager, four cardiac transplant/MCS advanced practice providers, three post-transplant nurse coordinators, three VAD coordinators, and two pre-transplant coordinators. Our team is supported by transplant pharmacists, dietitians, social workers, financial coordinators, a research nurse manager and two research coordinators. The Stanford heart transplant and MCS services work closely with consultants from the immunocompromised infectious disease program, psychiatry, and other consult services. The Heart Failure clinic is also supported by advance practice providers and nurse coordinators.
Dr. Ashley joined the Stanford faculty in 2006 after completing his medical residency and PhD in molecular cardiology at the University of Oxford, and is currently an Associate Professor of Medicine. His group is focused on the application of genomics to medicine. In 2010, he led the team that carried out the first clinical interpretation of a human genome. The paper, published in the Lancet, became one of the most cited articles in clinical medicine that year. His team now applies genome sequencing to the diagnosis of patients at Stanford Hospital where Dr Ashley directs the Clinical Genome Service and the Center for Inherited Cardiovascular Disease. Dr Ashley is a recipient of the National Innovation Award from the American Heart Association (AHA) and a National Institutes of Health (NIH) Director's New Innovator Award. He is a Principal Investigator of the Myocardial Applied Genomics Network (MAGnet), a member of the leadership group of the AHA Council on Functional Genomics, and a member of the Institute of Medicine (IOM) of the National Academy of Sciences Roundtable on Translating Genomic-Based Research for Health. Dr. Ashley mentors many cardiology fellows performing basic and translational research related to cardiovascular genomics
Dr. Fowler, who trained in Britain and came to Stanford in 1982, is Director of the Stanford Heart Failure Program and the Medical Director of the Cardiomyopathy Center at Stanford. A leader in the field of heart failure, Dr. Fowler played a pivotal role in developing the use of anti-adrenergic therapy for the treatment of patients with chronic heart failure. Under an IND for metoprolol in the 1980s, Dr. Fowler described improvement in contractile function in patients treated with metoprolol. After serving on the steering committee of the U.S. Carvedilol Heart Failure Study Group and other landmark trials, Dr. Fowler helped usher in the beta-blocker era of heart failure therapy. He also described the determinants of poor survival in heart failure patients based upon exercise testing with measurement of gas exchange, and established early guidelines for the selection of heart transplant recipients. Dr. Fowler’s technique of the “nitroprusside challenge” is now used commonly worldwide to assess the risk of post-transplant mortality due to pre-operative pulmonary hypertension. Finally, he continues to investigate the intersection between insulin resistance and heart failure. Dr. Fowler currently attends in the CCU and runs a busy heart failure outpatient panel where he works closely with general cardiology and advanced heart failure fellows on medical management, as well as patient evaluation for heart transplantation and mechanical circulatory support. Despite his advancing age, Dr. Fowler still makes lively contributions at the weekly cardiomyopathy center conference as well as the clinical heart transplant weekly meeting, and remains active in mentoring the research and career development of young physicians interested in careers in heart failure.
Dr. Haddad trained in general cardiology at the Montreal Heart Institute and subsequently completed advanced fellowships in cardiovascular imaging, heart failure, heart transplantation and pulmonary hypertension at Stanford.

Dr. Haddad is co-director of the Stanford Cardiovascular Biomarker and Phenotypic Core Laboratory. The research objectives of the laboratory are threefold: (1) to establish better metrics for the evaluation of cardiovascular function with a special focus of right heart function, (2) to better understand the immunological basis of cardiovascular recovery, and (3) to serve as a core reference laboratory. Dr. Haddad attends on the inpatient heart transplant and pulmonary hypertension services, in the echocardiography laboratory, and on the general cardiology service at Stanford.
