Their timing was ideal, given the recent establishment of the Artificial Heart Program in 1964, at the National Institutes of Health, which sustained the potential and promise of early yet crude device research of the 1950s and early 1960s and the federal government’s support for the peaceful use of nuclear energy. It was industrial scientists, not academic ones, who first proposed exploring radioisotopes as energy sources for artificial hearts. ![]() One federally funded project was the development of atomic hearts to save the increasing number of Americans dying of heart failure during that period. Large-scale, federally funded science and technology projects, such as the Apollo program and the Superconducting Super Collider, proliferated during the 1960s and 1970s, bolstered by enthusiastic reports from the scientific community with assertions of future benefits for Americans. A life-saving technology for one person has become a threat to society at large. ![]() The Federal Bureau of Investigation and local police begin a manhunt, while the National Heart Institute, government officials, and emergency-services personnel discuss contingency plans in the event that Pu contaminates the area. But then Gray is kidnapped by a madman who intends to remove and spray the heart’s hundred grams of Pu into the air, exposing thousands of people to dangerous levels of radiation. Both Bradfield and Gray enjoy their newfound celebrity as guest speakers describing their experience with the radioisotope-powered artificial heart, and Bradfield goes on to implant more hearts with similar success. His patient, Henry Gray, survives the experimental procedure, makes an impressive recovery, and is discharged from the hospital to resume his life. It is a story of William Bradfield’s daring efforts to save the life of a dying patient through the implantation of a mechanical heart powered by plutonium. Published in 1978, Heartbeat is a medical disaster novel by Eugene Dong and Spyros Andreopoulos that foretells the perils of an atomic heart. ![]()
