Sylvester Stallone’s son has died from heart disease, not from a drug overdose or as a result of dental surgery as originally believed.

Sage Stallonewho was found dead at his Hollywood Hills, Calif. home on July 13 — passed away as a result of atherosclerotic coronary artery disease, the Los Angeles Chief Coroner Investigator Craig Harvey confirmed in a statement to Celebuzz Thursday afternoon.

The condition is a thickening of the artery walls and is the most common cause of heart problems.

The 36-year-old’s toxicology results were also negative except for a small amount of the pain killer hydrocodone.

The amount of the drug in Stallone’s system was so small the coroner described it as “sub-therapeutic,” or unable to even give him pain relief as the levels were so minimal.

Harvey said he found no other health problems during his examination.

The full report into the death of The Expendables star’s son will soon be available.

“The report is expected to be available sometime within the next week,” Harvey said in a statement to Celebuzz.

It was feared that Stallone had died from an accidental overdose follow significant dental surgery.

At the time of his death, Stallone and his father Sylvester were estranged.

The young Stallone had appeared in the films The Evil Inside Me and his father’s film Daylight — which he also directed.

Sage is Sylvester’s son with his first wife, Sasha Ash.
