...autopsy revealed the cause of death to be an acute subdural hematoma, or blood clot, resulting from a head injury suffered sometime during the game, Patricia B. Elder, spokesman for the Dartmouth-Hitchcock Medical Center, said yesterday. A blood clot in the brain usually causes physical collapse within "minutes or hours," she added...
...long, thin plastic tube was inserted into an artery in his leg and gently pushed through the blood vessels all the way up into the aorta to the coronary arteries. A radiopaque substance was injected into the coronary vessels, and X-ray pictures were taken, revealing a blood clot. Doctors infused an anticlotting drug through the tube. Within an hour, the clot had dissolved, blood flow was reestablished, and Clendenen was spared extensive heart damage...
...Clot-Dissolving Streptokinase. Cardiologists are excited about an experimental technique that may be able to stop a blood clot-caused heart attack right in its tracks, and perhaps minimize damage to heart tissue. Says Garrett Lee of the University of California, Davis Medical Center: "Ten years ago, a patient admitted to the hospital would have been taken to the coronary care unit and continued to be monitored. It would be bed rest, oxygen and drugs to prevent such complications as arrhythmias and heart failure-but the heart attack would run its course." With this new technique doctors try to interrupt...
...restore the pathway, the body musters its repair troops, led by the platelets, tiny disc-shaped particles in the blood that help stop bleeding by promoting clotting. These "little plates" produce a chemical, thromboxane, that constricts blood vessels and signals other platelets to gather round. The platelets also manufacture a chemical that induces the artery's exposed underlying muscle cells to multiply. "If the injury is short-lived," says Russell Ross of the University of Washington School of Medicine in Seattle, "the proliferation process is reversible. But if the injury is chronic and repeated in the same sites...
DIED. Willard Frank Libby, 71, nuclear pioneer whose "atomic clock" for dating ancient objects won him the Nobel Prize in Chemistry in 1960; of a blood clot in the lung; in Los Angeles. A participant in the World War II Manhattan Project, Libby helped develop the gaseous-diffusion method of separating uranium isotopes. In the mid-'40s, he discovered that a radioactive isotope of carbon was a tiny but measurable part of all living matter and, decaying at a predictable rate, could be used to assign an age to dead organic archaeological and geological remains. An advocate of nuclear...
