Ralphie May's cause of death has been released by the Clark County Coroner's office in Nevada.

"Our Coroner/Medical Examiner has determined that Ralph May, 45, of Nashville, Tenn., died on Oct. 6, 2017, from Hypertensive Cardiovascular Disease," said the official Twitter account of Clark County alongside a photo of the comedian.

"The manner of his death was natural. We extend our sincere condolences to Mr. May's family and friends," they continued.

May died in a private residence in Las Vegas from cardiac arrest after battling with pneumonia.

The former "Last Comic Standing" finalist had performed a stand-up set the night before despite being ill for six weeks.

May, a finalist on the inaugural 2003 season of NBC's "Last Comic Standing" reality competition, had won the Casino Comedian of the Year award at the Global Gaming Expo two days before his death.

He is survived by his estranged wife Lahna Turner and their two children, daughter April June, 10, and son August James, 8.
