Rodney Diehl, D.O., is an interventional cardiologist with MidMichigan Health and is a member of the comprehensive heart and vascular team. This team includes cardiologists, interventional cardiologists, electrophysiologists, as well as vascular, thoracic and cardiovascular surgeons.

He currently sees patients at his main office in Midland, as well as at his satellite offices in Clare, Harrison and Mt. Pleasant.

Dr. Diehl brings more than 12 years of experience to his patients, offering expertise in advanced cardiac and peripheral vascular testing and treatment. He treats patients of all ages and is particularly sensitive to the rising incidence of heart disease in women.

Philosophy of Care

Dr. Diehl believes in aggressive preventive care before and after a heart attack to save patients’ lives. He focuses not only on a patient’s cardiovascular system, but also on overall health.

“I have a real desire to interact with patients and a long-term interest in heart and exercise physiology,” Dr. Diehl said. “I am committed to bringing compassionate cardiology and vascular services throughout the middle of Michigan.”

Special Interests and Procedures

Dr. Diehl’s advanced training enables him to offer cardiology, peripheral vascular and interventional cardiology services. Cardiology tests and procedures he provides include exercise stress testing, echocardiography and diagnostic cardiac catheterization. Peripheral vascular procedures he offers include endovascular thrombolysis and revascularization, abdominal aortic aneurysm and endovascular stent grafting, and arteriorgrams. Some of the interventional cardiology procedures he offers are angioplasty and placement of stents to restore blood flow in vessels narrowed by plaque, implantation of permanent cardiac pacemakers, and insertion and management of intra-aortic balloon pump.

Dr. Diehl and his wife have five children. He is also an avid hunter and fisherman.
