LOS ANGELES — The publicist for Kelsey Grammer says the actor has returned home from the hospital, four days after suffering a mild heart attack.

Stan Rosenfield said the "Cheers" and "Frasier" star is resting comfortably at his home on the Big Island. He says Grammer thanks those who called and wrote expressing concern.

Grammer was paddle-boating with his wife, Camilla, on Saturday when he experienced symptoms and was taken to a Kona hospital. Doctors determined the 53-year-old actor had suffered a heart attack that Rosenfield described as "mild."

Rosenfield says he doesn't know if Grammer has a history of heart trouble.
