Bill Clinton, the former US president, has been taken to hospital in New York after complaining of chest pains.
Clinton, 63, was taken to the Columbia Presbyterian hospital in Manhattan for a condition related to his heart.
Douglas Band, an adviser to Clinton, said he had two stents placed in one of his coronary arteries.
Band added that Clinton was in good spirits.
Clinton underwent quadruple bypass surgery in 2004 at the same hospital where he is now a patient.
