Billy Mays may have died of a heart attack, says a Florida medical examiner.
Initial findings in the autopsy on the famous TV pitchman showed that he had suffered from hypertensive heart disease, reports the AP.
There was no head trauma found, a significant point since earlier reports had speculated that Mays' bumping his head during a rough airplane landing on Saturday could have caused his death. He was found dead by his wife in his Tampa home Sunday morning.
Also, Hillsborough County Medical Examiner Vernard Adams notes that although Mays took prescription painkillers Tramadol and hydrocodone for hip pain — he was due to have hip surgery in the coming weeks — there was on indication of drug abuse.
Further tests are still needed before a cause of death is pinpointed.
