Because of the heart's physical vulnerability, medical treatment was largely unexplored until the end of the 19th century. To many it embodies the seat of emotion, the core of the soul, and it is the linchpin between life and death. As the book progresses he subtly introduces more complex, thought provoking ideas.History and culture imbue the human heart with a great deal of metaphoric and physical significance. This book is a relatively small volume and the writing begins rather simply. And lucky for us that he is able to write. Lucky for him that he has been able to pursue a career as a highly trained cardiologist. Sandeep Jauhar has been fascinated by the heart since he was a small boy. There is also Jauhar's personal story of heart disease in his own family and how it impacts his health, but how these diseases have affected all sorts of people from all levels of society. This is a good overview with enough depth in it too for the casual reader of how we have got to where we are now with our understanding and treatment of the heart. This and many other innovations and groundbreaking advances have lead us to the point where we move ever closer to the artificial heart. Inge Edler who made the connection that ultrasound that was being used to find battleships could also be used on the heart to see it working and John Heysham Gibbon who spent thirty years of his life developing a heart and lung machine to oxygenate the blood, opening the doors to being able to perform surgery on the heart without the patient dying.
There is William Harvey who discovered that the blood flowed down the arteries and somehow passed through the flesh and was pumped back up the veins. That journey from them to him will take us to the pioneers and mavericks who have discovered so much about it. Sandeep Jauhar has a close affinity with this organ, not only is he a practising cardiologist, but he only needs to go back to his grandparent's generation to find the roots of his own heart issues. It is the organ that is the very centre and essence of us. But what goes around comes around and modern research has shown how the heart can react and change shape as it reacts to feeling and trauma. For years was seen as the centre of our soul too, but that attitude changed with the rise of scientific understanding of the way it worked. Over your lifetime it will pump a staggering 158 million litres of blood. Over the course of a normal life, the heart will beat around 115,00 times a day which equates to 42 million times a year.
If there is one thing that you need more than your brain, then it is your heart.
