Summary
What is the real killer when it comes to heart disease? Can the right cardiac testing truly mean the difference between life and death? In today's episode, we are joined by Dr. John Osborne, a Harvard-trained, triple board-certified cardiologist and Co-Founder of ClearCardio, to break it all down…
Dr. Osborne earned his B.S. with honors from Penn State University, his M.D. magna cum laude from Jefferson Medical College, and a Ph.D. in cardiovascular physiology from Thomas Jefferson University. His postdoctoral training at Harvard Medical School and Brigham and Women's Hospital helped shape his expertise in non-invasive cardiology. Board-certified across multiple disciplines, his work focuses on preventive cardiology, metabolic syndrome, and cardiovascular genetics.
Recognized as the American Heart Association's Cardiac Care Provider of the Year and named a Top Doctor multiple times, Dr. Osborne has authored original research papers, book chapters, and delivered hundreds of international presentations. Through ClearCardio, he is advancing proactive cardiac care by integrating AI-powered imaging to detect plaque earlier, quantify risk more precisely, and empower patients before symptoms appear.
In this episode, we dive into:
-
What actually causes heart attacks and sudden cardiac death.
-
The role of soft plaque vs calcified plaque in coronary artery disease.
-
Why many heart attacks happen after a "normal" stress test.
-
The limits of stents and why they do not necessarily extend longevity.
