11-13-04- "I feel fine." Those are the words of Vice President Dick Cheney. He went to the hospital for about three hours today after experiencing shortness of breath.

The vice president has a history of heart trouble. An aide says tests found no heart abnormalities.

As he left, Cheney smiled and waved to people gathered outside George Washington Medical Center in Washington.

Cheney's cardiologist says he suspects the vice president has a
respiratory infection.

In a statement issued by the White House, Dr. Jonathan Reiner
says: "Tests ruled out any cardiac cause of the vice president's
symptoms. Tests also ruled out pneumonia and other pulmonary
causes. The vice president likely has a viral, upper respiratory
infection."

Cheney has had four heart attacks, although none as vice president.

Vice President Dick Cheney's health has been an issue since he suffered his first heart attack in 1978, when he was 37 years old.

He had a second attack in 1984 -- and after suffering his third heart attack, in 1988, Cheney had quadruple bypass surgery to clear clogged arteries.

In November 2000, Cheney suffered what doctors called a "very
slight" heart attack and had an angioplasty to open a clogged artery.

Cheney was back in the hospital in March 2001, after complaining
of chest pains. Doctors performed another angioplasty to reopen the
same artery.

After his fourth heart attack, Cheney quit smoking, began regular daily exercises for 30 minutes on a treadmill and said he began watching his diet.

He takes medication to lower his cholesterol.
