Paul O'Grady is set to leave hospital after tests showed that "all is fine", his management has said.
The 58-year-old comedian and TV star, who has suffered from two heart attacks in the past, was admitted to hospital after feeling unwell.
Singer Michael Ball and presenter Stephen Mulhern were brought in to front O'Grady's ITV teatime chat show while he was away.
But the star, in a statement in which he also thanked fans and hospital staff "for their kindness", said he is now "feeling much better" following the suspected angina attack.
His management said that Paul had not undergone surgery and ro utine tests showed that he is well.
Paul, who also presents a Radio 2 show, is expected to return to work after resting for a few days at home.
In a statement, BM Creative Management said: "Paul O'Grady was admitted to hospital on Monday afternoon after feeling unwell .
"He has undergone routine tests which have shown all is fine. He will be going home tomorrow to rest for a few days before returning to work."
Paul said: "I am feeling much better - I would like to thank all the nursing staff for their kindness and everyone who has texted or phoned in wishing me well."
Stephen Mulhern read messages of support as he stood-in for the host on his chat show.
Chris Moyles joked that the star still owed him "a tenner", Amanda Holden said that the comedian had "given me a scare" and Celebrity Big Brother winner Rylan Clark warned that Paul had to watch out that Mulhern does not "start putting things in your tea to keep his feet under your desk".
