(NEXSTAR) — Authorities in London have released the cause of death for Ozzy Osbourne, the legendary rocker who died “surrounded by love” late last month.
Ozzy Osbourne died of a heart attack: reports
Osbourne, 76, died of a heart attack, according to a death certificate reviewed by The New York Times and other England-based outlets. Cardiac arrest and coronary artery disease were listed among the causes, and Osbourne’s Parkinson’s diagnosis was noted.
Osbourne announced in 2020 that he had been diagnosed with Parkinson’s disease.
On July 22, Osbourne’s family confirmed in a statement that the Black Sabbath founder had died that morning, “with his family and surrounded by love.” Osbourne’s wife of more than 40 years, Sharon, signed the statement, as did his children, Aimee, Kelly, Jack and Louis.

Ozzy Osbourne’s final show
In early July, Osbourne joined the original members of the Black Sabbath — Tony Iommi, Geezer Butler and Bill Ward — for one final show in Birmingham, England.
“It’s my time to go Back to the Beginning….time for me to give back to the place where I was born,” Osbourne said in a social media post in February. “How blessed am I to do it with the help of people whom I love. Birmingham is the true home of metal. Birmingham Forever.”
In 2023, Osbourne said his touring days had “ended” due to spine damage he had suffered during an accident in 2019. That year, he canceled tour dates due to health problems, including a “bad fall” in which he said he injured vertebrae in his neck.

Osbourne was laid to rest on July 30.
Thousands of Black Sabbath fans paid their respects as his hearse made its way through the streets of Birmingham, the English city where he grew up and where the band was formed in 1968.
He is survived by Sharon and their three children — Kelly, Aimee and Jack — as well as his eldest son, Louis, from a previous marriage.
