Health - Dr Ross Walker with Denis Walter - Wed 01 Apr, 2026

In this episode of Nights with Denis Walter, Dr. Ross Walker discusses groundbreaking advances in preventive medicine, focusing on early detection of heart disease and longevity. He highlights two major scientific developments: the Cardioomic Score from the University of Hong Kong, which can predict heart disease risk up to 15 years in advance by analyzing hundreds of blood biomarkers beyond cholesterol and blood pressure, and research on small RNAs that correlate with lifespan, offering potential for early screening and therapeutic intervention. Dr. Walker emphasizes the critical need for prevention over reactive treatment, citing that only 0.5% of healthcare spending goes toward prevention despite its long-term cost savings. He also explores the role of the gut microbiome, frailty reversal via stem cell therapy, and the importance of early cardiac screening for those with family histories of heart disease. The episode includes listener calls addressing personal health concerns, including sudden cardiac death risks in young adults, post-surgical palpitations, and stiff heart syndrome, all met with practical, evidence-based advice. The conversation underscores a powerful theme: the future of medicine lies not in treating disease, but in predicting and preventing it decades before symptoms appear.
