Pioneer Heart Researcher Dies
GOLDEN VALLEY, Minn. (AP) _ Dr. Irwin J. Fox, a pioneer in developing procedures to measure the heart’s blood flow, has died of cancer. He was 59.
Fox died Sunday at his home in Golden Valley.
He was the original investigator and promoter in the 1950s and ’60s of the use of green dye for measuring the heart’s blood flow, said Dr. Claude Swayze, chairman of the Department of Anesthesiology at St. Paul-Ramsey and Hennepin County medical centers.
″That technique is still the standard reference for the measuring of cardiac output,″ Swayze said.
Swayze said Fox was an expert in dye-dilution techniques and wrote papers on radioactive microspheres in measuring the heart’s blood flow and on the sensors in the ventricular side of the heart.
Fox, a professor of physiology, began teaching at the University of Minnesota in 1963. Despite his illness, he continued working.
Fox, born in Germany in 1926, fled with his family to the United States at age 9. A Princeton graduate, Fox received his medical degree from New York University.
He is survived by his wife, Leone; two daughters and a son; his mother; and a brother. Services were held Monday in St. Louis Park.
