Dr Abdul Qadeer Khan has been declared healthy after a heart scare, the government said on Friday. Khan, 69, suffered minor chest pains on Tuesday and was taken to hospital earlier Friday to undergo an angioplasty, which checks arteries for blockages, before returning home. "Khan is absolutely fine and stable. He is healthy," President General Pervez Musharraf's press secretary and the country's military spokesman Major General Shaukat Sultan said.Sultan denied press reports that Khan had suffered a cardiac arrest. "He did not have any heart attack. He is back at his home," he added. The scientist's angioplasty took place at Pakistan's Armed Forces Institute of Cardiology and he was under observation by doctors from the clinic and from his own Khan Research Laboratories Hospital, Sultan said. Information Minister Sheikh Rashid told AFP late on Thursday that "Qadeer Khan felt pain in his chest two days ago."
