Chronic stress can stun a healthy heart
How Stress Can Cause a Heart Attack (And How to Heal) | Dr. Tara Narula
The conversation connects emotional strain to cardiovascular danger while treating resilience as a practical skill that can be developed before crisis.
- 1Chronic stress can drive cardiovascular harm, including arrhythmias, heart attacks, and broken-heart syndrome, even when arteries appear healthy.
- 2Resilience grows through acceptance, flexible thinking, purpose, spirituality, healthy habits, and meaningful connection rather than willpower alone.
- 3Parents and patients can practice resilience before adversity by managing fear, limiting digital stimulation, and building real-world support.

Narula explains how grief and emotional shock can flood the body with hormones that stun the heart, producing broken-heart syndrome even without blocked arteries.
The brief
Cardiologist Tara Narula argues that cardiovascular symptoms often carry emotional stories, and that medicine must connect psychological and physical health.
Chronic stress keeps the body’s alarm system activated, contributing to inflammation, plaque buildup, arrhythmias, heart attacks, and broken-heart syndrome.
Narula recounts sudden vision loss at 22 and the catastrophic thinking that followed, then explains how acceptance, purpose, and flexible thinking helped restore steadiness.
The practical prescription spans sleep, exercise, breathing, therapy, spirituality, nature, and social connection, with special attention to phones and children’s developing reward systems.
The episode’s central claim is preventive: resilience can be trained before crisis, helping people face illness, parenting pressure, grief, and uncertainty with greater flexibility.
