John W. Schaeffer, MD, FACC, is a board-certified cardiologist at University Hospitals Harrington Heart & Vascular Institute, directing cardiovascular services at University Hospitals Elyria Medical Center.

Dr. Schaeffer earned his medical degree with honors from The Ohio State University College of Medicine. His postdoctoral training included an internal medicine residency and cardiovascular disease fellowship at the University of Colorado Health Sciences Center in Denver. He started his own private practice with the launch of North Ohio Heart, Inc. in 1976, growing and overseeing a team of more than 40 cardiologists, and has been seeing patients in the western suburbs of Northeast Ohio ever since. He has extensive skill in the diagnosis and treatment of heart and vascular conditions, including coronary artery disease, heart failure, peripheral artery disease, heart arrhythmias such as atrial fibrillation and heart valve disease.

Beyond his clinical practice, Dr. Schaeffer is a member of nationally distinguished professional organizations including the American Society of Echocardiography, American Society of Nuclear Cardiology and Society for Angiography and Intervention (SCAI). He has received recognition as a fellow of the American Heart Association and American College of Cardiology and is a member of the Alpha Omega Alpha Medical Honor Society.

Dr. Schaeffer has also held leadership roles in these organizations. His service with the American College of Cardiology ranged from committee member for coding and clinical quality initiatives to being elected chairman of the Health Economic Committee and Governor of the Ohio Chapter. For the American Heart Association, he served as a trustee for the Northeast Ohio Affiliate Chapter and vice president of the executive board for the Scientific Council.

With a strong commitment to serving local communities too, Dr. Schaeffer has actively participated in Lorain County organizations throughout his tenure. This includes former roles as trustee for the Lorain County Community College Foundation, chairman for the Lorain County Community College continuing medical education consortium and president of the Lorain County Medical Society.

On the personal side, Dr. Schaeffer was happy to return home to start his cardiology practice. He very much appreciates the wonderful opportunity to have developed a large group practice that was quickly recognized as being a high quality, trusted resource to provide the right care to the right patient at the right time. He has been a sailor for more than 50 years and holds a sailor's philosophy of life which is, "since you can't change the direction of the wind, learn to adjust your sails".

Industry Relationships

University Hospitals is committed to transparency in our interactions with industry partners, such as pharmaceutical, biotech, or medical device companies. At UH, we disclose practitioner and their family members’ ownership and intellectual property rights that are or in the process of being commercialized. In addition, we disclose payments to employed practitioners of $5,000 or more from companies with which the practitioners interact as part of their professional activities. These practitioner-industry relationships assist in developing new drugs, devices and therapies and in providing medical education aimed at improving quality of care and enhancing clinical outcomes. At the same time, UH understands that these relationships may create a conflict of interest. In providing this information, UH desires to assist patients in talking with their practitioners about industry relationships and how those relationships may impact their medical care.

UH practitioners seek advance approval for certain new industry relationships. In addition, practitioners report their industry relationships and activities, as well as those of their immediate family members, to the UH Office of Outside Interests annually. We review these reports and implement management plans, as appropriate, to address conflicts of interest that may arise in connection with medical research, clinical care and purchasing decisions.
