Kelsey Grammer has said aloha to his hospital bed.

The actor's rep, Stan Rosenfield, said Wednesday that Grammer is back "resting comfortably at his Hawaiian residence," four days after suffering what doctors characterized as a "mild" heart attack.

"Grammer...wishes to thank those who phoned, emailed or wrote expressions of concern to him," Rosenfield said.

The five-time Emmy winner experienced symptoms Saturday morning after going paddleboarding with his wife, Camille, and was immediately taken to the hospital.
