TAMPA, Fla. — An official autopsy report released Friday found that cocaine use contributed to the heart disease that suddenly killed TV pitchman Billy Mays in June, but his family called the finding “speculative” and considered getting an independent look at the results.

The Hillsborough County medical examiner’s office previously determined that the bearded, boisterous TV spokesman had a heart attack in his sleep. His wife found him unresponsive in bed in their Tampa condo June 28.

Mays, 50, was a pop-culture fixture with his energetic commercials pitching gadgets and cleaning products like Orange Glo and OxiClean.

While heart disease was the primary cause of death, a report released Friday by the medical examiner listed cocaine as a “contributory cause of death.” The medical examiner “concluded that cocaine use caused or contributed to the development of his heart disease, and thereby contributed to his death,” the office said.

The office said Mays last used cocaine in the days before his death but was not under the influence of the drug when he died. Hillsborough County spokeswoman Lori Hudson said nothing in the toxicology report indicated the frequency of Mays’ cocaine use.

“We were totally unaware of any non-prescription drug usage and are actively considering an independent evaluation of the autopsy results,” Mays’ family said in a statement. The statement said the family was “extremely disappointed” by the release of the information by the medical examiner’s office. The report “contains speculative conclusions that are frankly unnecessary and tend to obscure the conclusion that Billy suffered from chronic, untreated hypertension.”

The tests also showed therapeutic amounts of painkillers hydrocodone, oxycodone and tramadol, as well as anti-anxiety drugs alprazolam and diazepam. Mays had hip problems and was scheduled for hip-replacement surgery the day after he was found dead.
