Former President Bill Clinton was in "good spirits" after undergoing surgery Thursday, his spokesman said.
Clinton, 63, had two stents placed in one of his coronary arteries at New York Presbyterian Hospital, spokesman Douglas J. Band said in a statement on the Clinton foundation's website. He was admitted to the hospital and met with his cardiologist after feeling discomfort in his chest.
"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," Band said.
In 2004, Clinton had quadruple bypass surgery to free four blocked arteries.
Secretary of State Hillary Rodham Clinton found out about her husband's operation after a meeting with President Barack Obama in the Oval Office and left for New York.
It was unclear how long Clinton was likely to be hospitalized.
