Former President Bill Clinton is back home less than a day after being rushed to the hospital for an emergency heart procedure.

Clinton, 63, left the Columbia Campus of New York Presbyterian Hospital early Friday after doctors performed a procedure to restore blood flow in an artery that was “completely blocked,” according to CNN. Doctors said there was no evidence of a heart attack.

The scare comes four and a half years after Clinton successfully underwent bypass surgery for four blocked arteries.

Secretary of State Hillary Rodham Clinton was with her husband Thursday night at the hospital. She was scheduled to leave Friday on a planned trip to the Middle East, but her departure was delayed until Saturday, CNN reported.

Clinton has maintained an active lifestyle since leaving the White House in 2001 and appeared ready to return to it: He was up and walking about two hours after his surgery. He also had to have his phone taken out of his hand as he was being wheeled into the operating room.

“He was on a conference call dealing with Haiti,” Clinton confidant Terry McAuliffe told CNN on Friday morning. “And I guarantee as soon as he gets back today he’s going to be back on the phone.”
