Howard Bush, M.D.

As chairman of the Department of Cardiology at Cleveland Clinic in Florida, Howard Bush, MD, oversees a staff of nine cardiologists and approximately 55 medical support personnel. He is director of the hospital’s Cardiac Catheterization Laboratory and head of its Chest Pain Alert Team, supervising the care management of patients that present in the emergency room with cardiac symptoms.

Under his leadership, Cleveland Clinic in Florida has earned significant industry recognition for its ability to deliver high quality cardiovascular care to patients. In 2007 it was named one of the nation’s 100 Top Hospitals® for cardiovascular care by Thomson Healthcare and one of just three hospitals in Florida to receive the American Heart Association’s Get With The Guidelines–Coronary Artery Disease Annual and Sustained Performance Achievement Award

Winner of the South Florida Business Journal’s 8th Annual Excellence in Healthcare Award in 2006 for a hospital-based program, the Chest Pain Alert Team at Cleveland Clinic is recognized as one of the best in the nation with a “door-to-balloon” time that averages 60-70 minutes. This is well below the national average of approximately two hours and exceeds the industry recommended guideline of 90 minutes for this national quality of care standard. It has been with Dr. Bush’s guidance and inspiration that the heart care team at Cleveland Clinic has achieved so much.

A graduate of Syracuse University, Dr. Bush earned his medical degree from New York Medical College. He completed advanced training in internal medicine at Baylor College of Medicine in Houston, Texas.

Dr. Boyd has been actively involved in developing and teaching new robotic procedures, using the da Vinci Surgical System, and is one of North America’s most experienced tele-robotic heart surgeons. He is currently involved in numerous clinical research activities that include utilization of automated vascular connectors in robotic bypass surgery and the development, application and teaching of intra-operative laser angiography systems. These efforts are aimed at improving patient outcomes after coronary bypass surgery. Dr Boyd has also been actively involved in preliminary cardiac regeneration studies using minimally invasive surgical techniques along with intracellular matrix and stem cell technology to re-grow damaged heart muscle and repair hearts weakened by infarcts.

Prior to joining Cleveland Clinic’s Department of Cardiothoracic Surgery in 2002, Dr. Boyd was director of the National Center for Advanced Surgery and Robotics at the London Health Sciences Centre in Ontario, Canada. While there he completed the world’s first closed-chest, beating-heart coronary artery bypass surgery with the use of the ZEUS® Robotic Surgical System.
