Radio personality David "Kidd" Kraddick died from cardiac disease and had an enlarged heart, according to his preliminary autopsy.

"His heart was enlarged," Deputy Coroner Dr. Granville Morse of Jefferson Parish, La., told The Dallas Morning News. "You have several vessels, and three were diseased -- the worst of which was 80 percent blocked. That combination, an enlarged heart and cardiac disease, when someone dies like this, it's usually dysrhythmia."
Kraddick's death will be ruled natural, though no official cause of death will be declared until Kraddick's toxicology report is finished, which might be at the end of the week.
Kraddick, 53, died Saturday at his Kidd's Kids charity golf tournament in a New Orleans suburb.
