The cause of "Rowdy" Roddy Piper's sudden death at 61 has been confirmed.
His death certificate, obtained by TMZ.com, states that the WWE Hall of Famer died of a heart attack triggered by a pulmonary embolism in his lungs on July 31, 2015.
Piper, who is survived by his wife Kitty and four children, was found dead that day in his home in Hollywood, California. He died in his sleep.
Piper was a professional wrestler for 45 years, the record confirms, and had a history of high blood pressure and hypertension, which is a known cause of clotting. He was previously diagnosed with Hodgkin's Lymphoma in 2006, though last November he declared was cancer free.
