Former U.S. Secretary of State Henry Kissinger has undergone angioplasty procedures to relieve blockages that impede blood flow to the heart.
Doctors in New York say Mr. Kissinger was admitted to the hospital on Tuesday and is resting comfortably at home after being released Thursday.
Angioplasty is a procedure for relieving blockages that inhibit blood flow to the heart, usually by inserting a catheter into an obstructed cardiac artery and inflating a tiny balloon.
The 81-year-old Kissinger served former Presidents Richard Nixon and Gerald Ford and shared the 1973 Nobel Prize for negotiating a diplomatic end to the Vietnam War.
