"Today President Bill Clinton was admitted to the Columbia Campus of New York Presbyterian Hospital after feeling discomfort in his chest," his counselor, Douglas Band, said in a statement. "Following a visit to his cardiologist, he underwent a procedure to place two stents in one of his coronary arteries. President Clinton is in good spirits, and will continue to focus on the work of his Foundation and Haiti's relief and long-term recovery efforts."
His wife, Secretary of State Hillary Clinton, and daughter Chelsea were at the hospital with him.
Clinton, 63, called the hospital's head of cardiology two days ago saying that he wasn't feeling well and having chest pains, MSNBC reports. He was originally scheduled to go to the hospital on Wednesday but postponed it until Thursday, according to MSNBC.
A stent is a metal mesh tube that opens an artery to improve blood flow. The procedure is commonly used as part of angioplasties.
Dr. Allan Schwartz, his cardiologist, says Clinton "did not have a heart attack or damage his heart" and that "the procedure went smoothly."
Schwartz expected that Clinton would "resume his very active lifestyle."
In September 2004, Clinton underwent a quadruple bypass Columbia Presbyterian, where doctors had found that some of the bypassed arteries had more than 90 percent blockage.
