New Details In James Gandolfini's Shocking Death

James Gandolfini's son Michael, 13, reportedly found his father "alive but in distress in the bathroom of their Rome hotel room" after the Sopranos star suffered a heart attack on Wednesday night.

NBC News reports that the teen called for help and hotel employees tried to resuscitate Gandolfini as they waited for paramedics to arrive. The actor was still alive when his ambulance arrived at the Policlinico Umberto I hospital around 10:20pm, but he was pronounced dead around 11pm.

ER doctor Dr. Claudio Modini says there are no suspicious factors involved in the star's death, adding that it was "probably a natural cause of death, myocardial infarction." However, it's widely known that Gandolfini has struggled with cocaine and alcohol addictions throughout his life, and prolonged cocaine use can cause all sorts of cardiovascular issues.

Modini said an autopsy would be performed within 24 hours ... no word on when the toxicology reports will be released.
