The Los Angeles County coroner has determined that James Caan, 82, died early this month of a heart attack and vascular disease.

TMZ was the first to get Caan's death certificate, on which the coroner gave specific details about the actor's death.

Myocardial infarction was indicated as the immediate cause of death, with coronary artery disease serving as a contributing factor.

The certificate states that the patient has chronic obstructive lung disease and congestive heart failure.

On the evening of July 6 at UCLA Medical Center in Los Angeles, Caan, well known for his role as Sonny Corleone in Francis Ford Coppola's "The Godfather," passed away.

His family broke the news of his passing via a tweet from his own account. The tweet concluded as it always does with his signature: "End of Β the tweet."

Caan, a native New Yorker who grew up in Sunnyside, Queens, also had a storied acting career, appearing in such films as "Brian's Song," "Misery," and "Elf."

In the 1971 telefilm Brian's Song, he played a football player who was dying of cancer. This role catapulted him to fame.
