TV pitchman Billy Mays apparently died of a heart attack, the Los Angeles Times is reporting.

Preliminary autopsy results show that Mays suffered from hypertensive heart disease, Hillsborough County Medical Examiner Vernard Adams said during a televised news conference this morning, The Times says.

Adams also said the autopsy showed no evidence of trauma to the head, either external or internal, that might have been caused by a rough airplane landing Mays experienced Saturday, the Times said.

Mays died Sunday in his Tampa, Fla., home.
