Report: Ultimate Warrior's autopsy reveals he died of a heart attack

After Ultimate Warrior died on Tues., April 8, 2014, in Arizona, just days after making multiple appearances for WWE at the Hall of Fame, WrestleMania 30, and Monday Night Raw, an autopsy was performed to determine the cause of death.

According to TMZ, the results are in and, as expected, he passed away after suffering a heart attack.

Officials tell TMZ ... the official cause of death for Warrrior -- real name James Hellwig -- was determined to be "Atherosclerotic/Arteriosclerotic Cardiovascular Disease" ... aka heart disease. Officials classified Warrior's death as "natural" -- meaning neither drugs nor alcohol were directly involved.

It should be noted that saying drugs weren't "directly" involved is simply stating he wasn't on drugs at the time of his death. It does not mean, however, that drug abuse throughout his life did not play a part in his demise. Warrior was very open in regards to his having taken steroids during his professional wrestling career, doing so to attain the body he would come to be famous for.

WWE will pay tribute to Warrior on tonight's (April 14) episode of Raw in Alabama.

Update: Just to be clear, it should be noted these are the preliminary findings to determine cause of death. The final report, with far more details, won't come out for some time.
