Michael Madsen's manager previously said, 'What we understand is Michael had a cardiac arrest and was found unresponsive in his Malibu home' on July 3. The 'Kill Bill' actor was 67.

In the months before his untimely death, Michael Madsen shared heart-tugging photos of his family and friends.

"The doctor's report is accurate that he died from heart failure," said Smith, referring to a statement that Madsen's cardiologist made to NBC4 Los Angeles. He added that "heart disease and alcoholism" were named as "contributing factors."
