Arnold Schwarzenegger Fights ‘Complications’ In Emergency Heart Surgery

Arnold Schwarzenegger is suffering "complications" after heart surgery at the Cedars-Sinai Medical Center in Los Angeles — with a simple procedure turning into a medical emergency!

The 70-year-old superstar had gone to the facility on March 29 for a catheter valve replacement. He's now listed in "stable condition" — with Schwarzenegger's health under close watch since 1997. That's when his first heart scare landed him in the hospital for surgery to fix a defective valve.

He lost his mother to a heart attack the next year — but Schwarzenegger went on to more action films and a stint as the governor of California. Earlier this week, the star had talked politics on CNN. He has several upcoming films in various stages of production.
