A medical examiner’s autopsy released on Thursday revealed that former pro wrestling star Randy “Macho Man” Savage died last month of heart disease, the AP reports. On May 20, the 58-year-old Savage — whose real name was Randall Poffo — lost consciousness and crashed his Jeep into a tree while driving on Route 694 in Pinellas County, Florida; he was pronounced dead at the hospital. The Tampa Bay area medical examiner determined that Savage suffered from an enlarged heart and blocked coronary arteries, and that his injuries from the accident were not significant enough to have caused his death. His wife, Lynn, suffered minor injuries in the crash.
