Heart To Heart : The Exquisite Machine

MON, SEP 19, 2022

The human heart is a miraculous organ, a marvel of construction unsurpassed by any man-made creation with its resilience and precision. It beats 100,000 times a day so that if you live 100 years, that would be more than 3 billion beats in a lifetime. In “The Exquisite Machine: the new science of the heart”, Professor Sian Harding explores the latest scientific developments and mysteries of the heart. Harding, a world leader in cardiac research at Imperial College in London, reveals the latest cardiac discoveries as well as the relationship between the emotions and heart function. In addition to being a powerful pump, the heart is super-sensitive – not just in responding to emotions but in creating them. And yes, you can die of “broken heart syndrome” – although there are profound differences between men and women. There is also a much deeper connection between the heart and the brain than we previously realized.

Since the heart is at the nexus of feeling we use the word in everyday conversation – heartfelt, heartache, the heart of the matter, a good heart. E E Cummings, the poet, famously wrote “I carry your heart with me” but writers have obsessed with this organ for centuries.

Dr Fady Joudah practices Internal Medicine at St Luke’s Baylor Medical Center in Houston, TX. When not administering to his patients, Joudah is an award-winning poet who first starting writing when working for Doctors Without Frontiers in Africa and published “Earth in the Attic”. He has now published five collections of poems and will read from his work and discuss how poetry informs his mission as a physician.
