Rodney Dangerfield has left hospital after his mild heart attack last week.

Medical tests on Monday night showed the attack was caused by the collapse of a small artery, a problem that can be corrected without surgery.

A hospital spokesman said: "The remedy for that is just a change in his medication, and his doctor says he'll be coming out of this fine."

Dangerfield was taken to hospital at the Cedars-Sinai Hospital in Beverly Hills last Thursday -­ his 80th birthday and Thanksgiving.

The previous night Jay Leno's The Tonight Show paid a special tribute to the comic's 60-year career.

Dangerfield is working on his autobiography It's Not Easy Being Me, due out next year.
