About Kenneth M. Lightheart
About The Provider
Kenneth Lightheart is a cardiologist with subspecialty expertise in nuclear cardiology and a particular interest in transesophageal echocardiography—a relatively low-stress test that lets clinicians see the heart from a unique vantage point. He believes the best decisions are made together, taking time to explain the “why” behind every recommendation so patients can confidently choose the next step in care.
Dr. Lightheart earned a BA in Korean Studies from Brigham Young University and an MD from Oregon Health & Science University. He completed internship at Legacy Portland Hospitals and residency at David Grant Medical Center, Travis Air Force Base. He is board-certified by the American Board of Internal Medicine in Cardiovascular Disease and by the Certification Board of Nuclear Cardiology. A U.S. Air Force veteran, he achieved the rank of Major—experience that honed his focus on preparation, precision, and staying on time for patients.
Originally from Springfield, Oregon, he enjoys golf, tennis, jogging, traveling, and time spent playing games with his family.
