Michael Madsen's Official Cause Of Death Determined

The cause of death for Michael Madsen, best known for his roles in "Reservoir Dogs," "Kill Bill," and "Donnie Brasco", has been confirmed.

He died of cardiac arrest brought on by cardiomyopathy, coronary artery disease, and chronic alcoholism, according to his death certificate from the L.A. County Medical Examiner.

Another contributing factor was thromboembolic disease – a condition where blood clots form in blood vessels and then travel to obstruct another vessel, causing a thromboembolism.

Deputies responded to Madsen's home on July 3 after a 911 call, where the actor was pronounced dead at the scene. He was 67.

The prolific actor's managers Susan Ferris and Ron Smith and publicist Liz Rodriguez released a statement following his departure: “In the last two years Michael Madsen has been doing some incredible work with independent film including upcoming feature films Resurrection Road, Concessions and Cookbook for Southern Housewives, and was really looking forward to this next chapter in his life. Michael was also preparing to release a new book called Tears For My Father: Outlaw Thoughts and Poems currently being edited. Michael Madsen was one of Hollywood’s most iconic actors, who will be missed by many.”

Madsen appeared in many Quentin Tarantino films including the role of Vic Vega/Mr. Blonde in "Reservoir Dogs", Budd in "Kill Bill" Volume 1 and Volume 2, Grouch Douglass/Joe Gaga in "The Hateful Eight" and Sheriff Hackett in "Once Upon a Time … in Hollywood".

He also starred in "Thelma & Louise", "Free Willy", "Species", and "Donnie Brasco".

While best known for his big-screen appearances, Madsen also worked in television over the decades.

He had a recurring role on "24" in 2010, and guested early in his career on such hit shows as "St. Elsewhere", "Crime Story" and "Quantum Leap". Later on, Madsen appeared in "CSI: Miami" and "Blue Bloods", among others.
