Inside Ozzy Osbourne’s Cause of Death: What Is Myocardial Infarction?

Ozzy Osbourne’s cause of death has been confirmed.

The former Black Sabbath frontman died at 76 after suffering an “acute myocardial infarction” and an “out of hospital cardiac arrest,” according to his death certificate, as reported by The New York Times.

Contributing factors to his passing were listed as “coronary artery disease and Parkinson’s disease with autonomic dysfunction.”

As Star previously reported, members of the Osbourne family announced the Prince of Darkness had died “surrounded by love” on July 22.

“It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning,” the statement shared by his wife, Sharon, and kids Kelly, Jack, Aimee, and Louis Osbourne read. “We ask everyone to respect our family privacy at this time.”

On July 30, friends, family and fans gathered for the late rocker’s funeral procession through the streets of Birmingham, England. The procession was followed by a private funeral.

Star takes a deep dive into Ozzy’s health conditions prior to his death.

What Is Myocardial Infarction?

Myocardial infarction is the medical term for a heart attack. It occurs when something – often a blockage – prevents the proper amount of blood flow to the heart.

According to the Cleveland Clinic, more than 800,000 people in the United States suffer a heart attack per year – many of which are connected to coronary artery disease.

Symptoms of a heart attack can include palpitations, shortness of breath, chest pain, dizziness, nausea and more. However, men and women often experience different sets of symptoms.

When Was Ozzy Osbourne Diagnosed With Parkinson’s Disease?

Ozzy was diagnosed with Parkinson’s disease – a neurodegenerative disorder that affects movement – in 2003, according to People. However, the musician did not go public with his diagnosis until more than 15 years later.

During a 2020 sit-down with Good Morning America, Sharon Osbourne clarified that her husband’s condition was “not a death sentence by any stretch of the imagination.”

“It’s like you have a good day, a good day, and then a really bad day,” she added at the time.

As for why he finally chose to open up about his diagnosis publicly, Ozzy admitted on GMA: “I’m no good with secrets. I cannot walk around with it anymore ’cause it’s like I’m running out of excuses, you know?”

Inside Ozzy Osbourne’s Other Health Issues

Aside from his battle with Parkinson’s disease, Ozzy also suffered severe back issues after a nearly fatal ATV accident in late 2003 that left him in a coma for eight days and resulted in several broken ribs, a cracked vertebra and a broken collarbone. His recovery was partially documented on the MTV reality series The Osbournes.

“I’ll never go near one of those damn bikes again,” he told the Mirror at the time, per Today. “I am lucky to be here today and not paralyzed … The doctors tell me every day it could have been a lot worse. I could be dead.”

In 2019, he also had a “bad fall” and had to have surgery on his neck – which the “Paranoid” artist said “screwed all my nerves” in his 2020 interview on GMA.

His various medical issues eventually left him unable to walk in the days leading up to his final farewell concert – but shortly before his death, Ozzy found a silver lining to his health woes.

“I have made it to 2025. I can’t walk, but you know what I was thinking over the holidays? For all my complaining, I’m still alive,” he said on an episode of his SiriusXM radio show, Ozzy’s Boneyard, that aired earlier this year. “I may be moaning that I can’t walk, but I look down the road and there’s people that didn’t do half as much as me and didn’t make it.”
