Summary
Written by a model from the transcript; not yet reviewed.
Dr. Tara Narula, a board-certified cardiologist at Lenox Hill Hospital and chief medical correspondent for ABC News, explains how psychological stress, anxiety, and trauma manifest as physical heart problems and cardiovascular disease. In conversation with the host of The School of Greatness, Dr. Narula discusses the phenomenon of stress-induced heart attacks, known as Takotsubo cardiomyopathy, where a surge of hormones like adrenaline and cortisol stuns the heart. She argues that modern medical institutions fail patients by separating mental health from clinical cardiology, and she shares practical tools from her book, The Healing Power of Resilience, to help listeners build emotional strength and protect their physical health.
Throughout the episode, Dr. Narula explains how chronic activation of the fight-or-flight nervous system leads to inflammation, plaque rupture, and heart failure. She offers strategies drawn from psychology and her own experience recovering from partial vision loss at age 22, including acceptance, flexible thinking, and nurturing social connections. Listeners will learn actionable methods to lower cortisol, recognize the dangers of chronic stress, and transform personal setbacks into sources of strength and purpose.

- Practice acceptance and flexible thinking when facing a traumatic diagnosis to prevent chronic stress from damaging your cardiovascular system. 13:51
