Former Secretary of State Henry A. Kissinger, 77, was hospitalized in New York on Wednesday with what doctors are calling a limited heart attack. He is said to be doing well. Kissinger, who served Presidents Richard Nixon and Gerald Ford, won a Nobel Peace Prize for his role in bringing an end to the Vietnam War but was later criticized for his role in the invasion of Cambodia. In 1982, he underwent heart bypass surgery. The Associated Press reports that, despite his current heart condition, Kissinger is expected to attend a dinner next Wednesday that Secretary of State Madeleine Albright is hosting for former secretaries of state.
