Wes Leonard, star of the Fennville High basketball team, died of cardiac arrest brought on by a condition called dilated cardiomyopathy, said the Ottawa County, Mich., medical examiner Friday.
People with dilated cardiomyopathy have enlarged and weakened hearts that cannot pump blood through the body efficiently. In some cases, including Leonard's, the condition leads to sudden cardiac arrest. Leonard, a 16-year-old junior who had scored more than 1,000 points in his high school basketball career, had just completed a game-winning overtime shot when he collapsed Thursday night.
The American Heart Association has advised that children with dilated cardiomyopathy should not play competetive sports "because of the possibility of a sudden collapse or increased heart failure."
