Eugene Anson Stead Jr., M.D., former chairman of Duke University's medicine department and an innovator in the collection of medical data, died in his sleep Sunday at age 97.
Stead was chairman of Duke's Department of Medicine from 1947 to 1967 and was a founder of the Duke Clinical Research Institute. He also was medical school dean at Emory University from 1945 to 1946.
Stead's work with cardiac catheterization formed the basis for much of what is now used in the treatment of heart failure. In 1969, Stead led a research group at Duke that applied then-new computer technology to the collection of data from patients undergoing coronary angiography. The Duke Databank for Cardiovascular Disease was the predecessor to DCRI, the world's oldest and largest compilation of information providing scientific evidence on the outcomes of cardiac care.
