Ninoy was moved to the Philippine Heart Center, where he suffered another heart attack. Refusing to be treated at the Center for fear of threats on his life, he requested permission to go to the US for treatment or be brought back to his cell.
His request was granted and Ninoy was allowed to go to the US for surgery, together with his entire family. This was arranged after a secret hospital visit by Imelda Marcos. This "emergency leave" was set when Ninoy supposedly agreed to the First Lady's 2 conditions: that if he leaves, he will return; and while in America, he should not speak out against the Marcos regime.
Ninoy was operated in Dallas, Texas and made a quick recovery. After which, he decided to renounce the agreement saying, "a pact with the devil is no pact at all".
He, Cory and their children started a new life in Massachusetts. He continued to work on two books and gave a series of lectures while on fellowship grants from Harvard University and Massachusetts Institute of Technology. His travels across the US had become opportunities for him to deliver speeches critical of the Marcos government.
