This week, Dr. Kahn explores a variety of "mini-topics," including the presence of microplastics in fish, the link between heart disease and cancer, the ineffectiveness of the ketogenic diet for cardiovascular disease, and the lifetime risk and consequences of atrial fibrillation. Dr. Kahn also embraces the theme of "fighting heart disease like cancer" by presenting case studies from two recent patients at the Kahn Center for Cardiac Longevity, showcasing the center's approach to aggressive treatment that mirrors cancer care norms.
