In this episode of the Clear Cardio podcast, host Dr. John Osborne interviews Dr. Paresh Mehta, a gastroenterologist, former leader of the physician‑owned GI Alliance, and a Clear Cardio patient. The conversation weaves together Mehta’s professional journey—building GI Alliance to ~1,000 doctors across 15+ states and its eventual sale to Cardinal Health—with his personal experience of early cardiovascular risk detection using Clear Cardio’s cardiac CT and AI platform. They introduce the “cardiac colonoscopy” metaphor, describing low‑dose cardiac CT as a preventive screening tool that visualizes subclinical plaque decades before symptoms appear, analogous to how colonoscopy detects polyps before cancer develops. The dialogue expands to the emerging link between metabolic‑associated steatohepatitis (MASH/MAFLD) and cardiovascular disease, noting that cardiac CT also captures liver density, enabling a “poor‑man’s” fatty‑liver screen. Both hosts champion a shift from reactive, intervention‑driven cardiology to proactive, lifestyle‑ and medication‑based prevention, emphasizing the need for broader adoption of early‑detection technologies. Mehta shares his positive patient experience with Clear Cardio’s high‑touch service, from pre‑procedure prep to post‑scan review, and both express enthusiasm for future collaborations on cardiometabolic‑GI topics and for demonstrating plaque regression in follow‑up scans.
