Ted Agu, the Cal defensive lineman who collapsed during an offseason workout in February, died of a heart condition known as hypertrophic cardiomyopathy, authorities said Wednesday.
Hypertrophic cardiomyopathy is often undiagnosed because of the few, if any, symptoms. It is known as an excessive thickening of the heart muscle, making it difficult for victims to pump blood from the heart and in some cases can cause shortness of breath.
Agu, 21, collapsed around 6 a.m. on Feb 7. Team medical personnel realized Agu was having a difficult time roughly 150 yards outside of Memorial Stadium and transported him to a cart.
The Cal medical team attempted CPR and a defibrillator was used, authorities said. He was then transported to Alta Bates Medical Center in Berkeley, where he died.
Cal has since started up the Ted Agu Memorial Scholarship Fund to create scholarship endowment for student-athletes.
Hypertrophic cardiomyopathy gained notable attention in 1990 with the death of basketball star Hank Gathers of Loyola Marymount University.
A review published in the New England Journal of Medicine in 2003 stated that hypertrophic cardiomyopathy is the leading cause of sudden death among athletes.
