ROME (AP) — Hospital officials in Rome say U.S. actor James Gandolfini died after suffering cardiac arrest.

Dr. Claudio Modini, head of the emergency room at the Policlinic Umberto I hospital, said Gandolfini arrived at the hospital at 10:20 p.m. Wednesday and was pronounced dead at 11 p.m. after reanimation efforts in the ambulance and hospital failed.

He told The Associated Press on Thursday that an autopsy would be performed starting 24 hours after the death, as required by law.
