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 Husseys 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 kanon of care laid out for him aby the attending cardiologist, or politely decline and apply everything hed learned about the heart to a recovery protocol that would look massively different than what the doctors were recommending. 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.
