Kalas died of cardiovascular disease
Hall of Fame broadcaster had high blood pressure
PHILADELPHIA -- Legendary Phillies broadcaster Harry Kalas died Monday afternoon from heart disease.
A spokeswoman at the Washington D.C. chief medical examiner's office told The Associated Press that an autopsy revealed Kalas, 73, had high blood pressure and suffered from atherosclerotic cardiovascular disease. The disease is a major cause of heart attacks and strokes because of plaque buildup restricting blood flow in arteries.
Kalas collapsed inside the Phillies broadcast booth at Nationals Park and died about an hour later.
Kalas, who was the Hall of Fame's Ford C. Frick Award recipient in 2002, is survived by his wife, Eileen, and sons Todd, Brad and Kane.
Private funeral and burial services are planned for early next week.
