For centuries, the human heart seemed beyond our understanding: an inscrutable shuddering mass that was somehow the driver of emotion and the seat of the soul. As cardiologist and bestselling author Sandeep Jauhar shows in Heart, it was only recently that we demolished age-old taboos and devised the transformative procedures that changed the way we live. Deftly alternating between historical episodes and his own work, Jauhar tells the colorful and little known story of the doctors who risked their careers and the patients who risked their lives to know and heal our most vital organ, braiding those tales of discovery, hubris, and sorrow with moving accounts of the patients he's treated over the years. He also confronts the limits of medical technology, boldly arguing that future progress will depend more on how we choose to live than on the devices we invent. Affecting and engaging, Heart takes the full measure of the only organ that can move itself.
