The cause of death for Michael Madsen has been confirmed. The prolific Reservoir Dogs, Kill Bill and Donnie Brasco actor died of cardiac arrest brought on by cardiomyopathy, coronary artery disease, and chronic alcoholism. 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., according to his death certicate from the L.A. County Medical Examiner obtained by TMZ.

Deputies responded to the actor’s home on July 3 after a 911 call and he was pronounced dead at the scene. He was 67.
