Bernie Sanders had a heart attack this week, his presidential campaign said on Friday as he left a Las Vegas hospital, following three days of near silence from the candidate and his advisers about his health. He was taken to an urgent care facility, where doctors determined that he should be transferred to a hospital. He was then taken by ambulance to Desert Springs Hospital Medical Center. He spent three nights at the hospital and canceled his events and appearances for the week. Sanders will take a cocktail of drugs to reduce his risk of another heart attack, including powerful anti-clotting medications that require close monitoring for a month.
