Dick Cheney Released from Washington, DC, Hospital

Vice President Cheney was released from the George Washington University Hospital today, three days after he was admitted for fluid retention related to his coronary artery disease.

A spokesman for the 69-year-old Cheney said he took ill on Friday afternoon and was admitted to the hospital for further testing on the recommendation of his doctors there.

The illness was a result of a progressive retention of fluid related to Cheney's coronary artery disease. He received IV medication and his health "markedly improved," his office said Saturday evening.

Cheney's daughter Liz said on Sunday that her dad was "feeling better."

"He's had coronary artery disease, you know, for as long as I can remember, and I'm sure he'll deal with this situation the way he's dealt with everyone in the past, which is to work with his doctors," the former vice president's daughter said on Fox News Sunday.

Cheney has a long history of heart problems. He has had five heart attacks, the first in 1978 when he was just 37 years old and the fourth in November 2000 after he and former President George W. Bush were elected to the White House.

In 2001 Cheney had a pacemaker installed into his chest and last September he underwent elective back surgery to treat lumbar spinal stenosis.

Cheney was last admitted to the George Washington Hospital on Feb. 22 after experiencing chest pains. His doctors later said it was a mild heart attack -- his fifth. He was released on Feb 24.

That hospital stay forced the former vice president to miss a breakfast with his former boss, George W. Bush, and hundreds of former White House and campaign staffers.

That event, sponsored by the Bush-Cheney Alumni Association, was to be the first time the two met in person since they left office in January 2009.

Instead, Bush dropped by to visit Cheney at his home in Virginia on Feb. 25. Cheney and Bush, both sporting dark suits, shook hands and exchanged grins on the steps of Cheney's residence in McLean, Va., before turning to wave to the ABC News camera.

"Mr. President, welcome," began Cheney.

"Lookin' good," replied Bush.

"Holding up," said Cheney.

"Lookin' good," said Bush again.

"Could be worse," Cheney noted.

Cheney has kept himself in the public eye since leaving the White House, selectively choosing interviews and appearances to deliver stinging rebukes of the Obama Administration.

In February, he predicted that Obama will be a "one-term president." After the thwarted Christmas Day bomb plot, Cheney said that Obama was "trying to pretend we are not at war" with terrorists.

This is in stark contrast to former President Bush who has been largely invisible, living in Dallas and working on his presidential memoirs. The former president has given occasional speeches to business groups but has held his tongue when it comes to commenting on the Obama Administration.
