FRANK Sinatra (81), was admitted to hospital yesterday suffering from what doctors said was a heart attack.
He was undergoing treatment at Cedars Sinai Medical Centre in Los Angeles. Dr Rex Kennamer said the prognosis for the entertainer was good.
A spokeswoman for the Beverly Hills hospital said Sinatra was brought in by paramedics early in the morning.
"He appears to have had an uncomplicated heart attack and is undergoing tests, observation and treatment," she quoted Dr Kennamer as saying of him.
She said Sinatra was in a regular room at the hospital and not in the intensive care unit.
The entertainer was in the same hospital on Monday night for an undisclosed reason and was released on Tuesday morning.
He spent eight days in Cedars Sinai last November after being admitted for a pinched nerve. He later developed pneumonia.
Last month, Nancy Sinatra told ABC television her father was in "pretty good" health.
"I think he is wishing he were about 20 years younger. But then so am I - aren't we all?" she said.
The Hoboken, New Jersey born son of an Italian immigrant firefighter was asked what he wanted for Christmas in December; Nancy Sinatra said her father's wish was to be here to celebrate another Christmas.
He has made more than 100 albums in his extraordinary singing career, including such highlights as New York, New York, and My Way, written by Paul Anka.
He also appeared in 50 films including the 1953 film From Here to Eternity, for which he won an Academy Award for his performance as Private Maggio.
In 1955, he was nominated for an Academy Award for his performance as a drug addict in The Man with the Golden Arm.
