Sylvester Stallone's son died of heart attack, says coroner

  • Sage Stallone, the son of actor Sylvester Stallone, died of a heart attack after a toxicology report showed no signs of excessive drug use.

    Stallone, who died at age 36 on July 13, suffered from coronary heart disease caused by atherosclerosis, which resulted in the heart attack, according to an official with the Los Angeles County Coroner.

    Stallone had a small amount of the sedative hydrocodone in his body but it was at an acceptable level and one that is found from taking over-the-counter pain medication. No other drugs were found in his system.

    Sage Stallone's body was found at his Hollywood home after concerns were raised by family and friends who had not heard from him for a day.

    Sage Stallone was the younger of two sons from the Rocky star’s first marriage to Sasha Czack, whom he divorced in 1985 after 10 years of marriage.

    He appeared in several films, most notably with his father in 1990's Rocky V playing the title character's son.
