*Former President Bill Clinton was taken to New York’s Columbia Presbyterian Hospital this afternoon with chest pains and underwent more heart surgery, his office said in a statement.

Physicians inserted two stents into his native coronary artery after one of the bypass graphs from an operation five years ago became obstructed.

“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 counselor, Douglas J. Band, said in a statement released Thursday afternoon by the former president’s office.

Secretary of State Hillary Clinton, at the White House Thursday for a meeting with President Obama, was spotted leaving the Oval Office a short while ago and did not seem “too concerned” or “in a rush,” according to sources quoted by ABC News.

In 2004, Clinton underwent a four-hour quadruple-bypass surgery and later developed rare complications affecting his lungs that required a second operation six months later. All indications are that his current condition is not life threatening, according to ABC News.

One friend of Clinton was quoted as saying he had been feeling tired in recent weeks. The former president serves as the United Nations special envoy to Haiti and has been spending much of his time in recent weeks trying to coordinate relief and recovery efforts for the Caribbean island after a devastating earthquake claimed more than 200,000 lives. Clinton just returned a few days ago from his second trip there since the disaster.
