PodcastDX is an interview based weekly series. Guests share experience based medical insight for our global audience. We have found that many people are looking for a platform, a way to share their voice and the story that their health journey has created. Each one is unique since even with the same diagnosis, symptoms and the way each person will react to a diagnosis, is different. Sharing what they have experienced and overcome is a powerful way our guests can teach others with similar ailments. Many of our guests are engaging in self-advocacy while navigating a health condition, many are complex and without a road-map to guide them along their journey they have developed their own. Sharing stories may help others avoid delays in diagnosis or treatment or just give hope to others that are listening. Sharing is empowering and has a healing quality of its own. Our podcast provides tips, hints, and support for common healthcare conditions. Our guests and our listeners are just like you- navigating the complex medical world. We hope to ease some tension we all face when confronted with a new diagnosis. We encourage anyone wanting to share their story with our listeners to email us at info@PodcastDX.com Language: en Genres: Alternative Health, Health & Fitness, Medicine Contact email: Get it Feed URL: Get it iTunes ID: Get it |

Heart, Brain & Immunity: New Clues After a Heart Attack
Episode 2
Monday, 25 May, 2026
After a heart attack, the story doesn't end in the arteries. In this episode of PodcastDX, Lita and Jean Marie explore new science showing how the heart, brain, and immune system talk to each other during and after a heart attack—and how that three-way conversation can either protect the heart or make damage worse. We break down a "triple‑node" loop discovered in recent research, where vagus‑nerve sensory fibers in the heart send danger signals to the brain, the brain ramps up fight‑or‑flight output, and the immune system responds in ways that can change healing, scarring, and heart rhythm. Using plain language, we walk through what immune cells like neutrophils and macrophages do in the damaged heart, why inflammation is helpful at first but harmful if it lingers, and how this ties into dysautonomia and other nervous system issues some people face after a cardiac event. We also talk about what this emerging "heart–brain–immune" axis could mean for future therapies—from calming overactive nerve circuits to targeting specific inflammatory pathways—while emphasizing that these findings are early and mostly from animal models. Whether you are a patient, caregiver, or just curious about how interconnected the body really is, this episode offers a hopeful, accessible look at what comes next in heart attack research and recovery.
