US: US Vice President Dick Cheney, who has a history of heart attacks, went to a Washington hospital on Saturday after experiencing shortness of breath but later left for home and said he was fine.
Mr Cheney (63) has had a cold and aides said his cardiologist, Dr Jonathan Reiner, advised him to visit George Washington University Hospital out of caution.
Dr Reiner later issued a statement ruling out "any cardiac cause" of Mr Cheney's symptoms and also ruled out pneumonia and lung problems.
"The Vice President likely has a viral, upper respiratory infection," Dr Reiner said in a statement.
Walking toward his motorcade as he left the hospital, Mr Cheney told reporters, "I feel fine." His wife, Lynne, was with him.
He has had four heart attacks, the first in 1978 when he was 37, but none while he has been Vice President.
