Washington (CNN) - Former Vice President Dick Cheney suffered a mild heart attack Monday when he complained of chest pains and was hospitalized, his office said Tuesday.
"Lab testing revealed evidence of a mild heart attack," the statement said. "He underwent a stress test and a heart catheterization. He is feeling good and is expected to be discharged in the next day or two."
During the catheterization, which took place at George Washington University Hospital, doctors examined blood flow to the heart and tested how well the heart was pumping.
In the procedure, a doctor inserts a catheter, a thin plastic tube, into an artery or vein in the arm or leg and threads it into the chambers of the heart or into the coronary arteries. The test can measure blood pressure within the heart and how much oxygen the blood contains.
