Understanding the Heart

Surprising Insights into the Evolutionary Origins of Heart Disease—and Why It Matters

By Stephen Hussey

‘The most mind-blowing information on heart disease. . . . I consider this to be the best book I’ve ever read on cardiovascular health.’—Ben Greenfield, New York Times bestselling author

Despite what we might think living in a world filled with Covid, cancer, famine and obesity – heart disease remains the number-one killer in the world. There continue to be huge investments in advanced medical procedures and more and more powerful pharmaceutical drugs, but the rate of heart disease continues to rise.

As a type 1 diabetic, Dr Stephen Hussey had always known that he was at two to four times greater risk of developing heart disease. As a result, he has dedicated his entire adult life to understanding the heart, to prevent himself from becoming a statistic. Dr Hussey believes that the continued rise in heart disease is due in part to fundamental misunderstandings about how the heart really functions and how to keep it healthy. These misunderstandings can result in improper medical approaches and off-target intervention therapies.

Sadly, Dr Hussey’s worst nightmare came true. He suffered a ‘STEMI,’ a blockage in the left anterior descending artery of his heart. STEMIs are typically so fatal that they are known as ‘widowmakers.’ Only 12 per cent of those who experience them outside of a hospital setting survive. Dr Hussey was among the lucky 12 per cent, but faced a difficult decision during his recovery: follow the standard of care laid out for him by the attending cardiologist, or politely decline and apply everything he’d learned about the heart to a recovery protocol that would look massively different than what the doctors were recommending.

In Understanding the Heart, Dr Hussey shares the information that guided him through the highest-stakes decision of his life, including: 

  • A large body of research suggesting that the heart is not the main mover of blood in the body, and what that means for your overall health
  • The evolutionary origins of the nervous system and how these manifest today in rampant rates of heart disease
  • Deep analysis of the widely accepted idea that saturated fat and cholesterol will clog your arteries
  • The importance of reducing oxidative stress for a heart healthy lifestyle

In Understanding the Heart, Dr Stephen Hussey lays bare everything he has learned in his deep investigation into the heart and guides you on a path to prevent disease in the context of a highly diseased modern world in order to enjoy lifelong good health.

Reviews and Praise

“The most mind-blowing information on heart disease. . . . I consider this to be one of the best books I’ve ever read on cardiovascular health.”―Ben Greenfield, New York Times best-selling author

“Finally, a holistic, evolutionary-rich, and practical approach to understanding heart disease. This book is powerful, informative, and approachable.”—Dr. Bill Schindler, author of Eat Like a Human

“With simple prose, and sprinkled with many entertaining personal stories, Dr. Stephen Hussey reveals the magic in biology and dispels a number of myths about heart disease. You will learn that the heart is a vortex, not a pump, that its preferred fuels are fats and ketone bodies, that the blood flows through the vessels via electromagnetic energy driven by exclusion zone water, and much else. This book will make you think of your heart in a totally new way.”—Stephanie Seneff, PhD, author, Toxic Legacy

"Exceptionally 'reader friendly' in organization and presentation, making this an ideal and highly recommended addition to community, college, and university library Health/Medicine collections. Informative and iconoclastic."—Midwest Book Review
