The death certificate listed the primary and secondary causes, painting a clear picture of the final medical events.

1. Acute Myocardial Infarction (Heart Attack)

The immediate event that led to his death was a heart attack, technically referred to as an acute myocardial infarction. This sudden and catastrophic cardiac event was the final trigger.

2. Out-of-Hospital Cardiac Arrest

Following the myocardial infarction, Osbourne suffered a cardiac arrest. This means his heart suddenly stopped beating effectively, leading to his passing at his home, as confirmed by family statements.

3. Coronary Artery Disease (CAD)

Coronary Artery Disease was listed as an underlying condition. CAD is a common heart condition where the major blood vessels that supply the heart with blood, oxygen, and nutrients become damaged or diseased.

This long-term condition significantly contributed to the heart attack and subsequent cardiac arrest.

4. Parkinson's Disease (Parkin 2)

For years, Ozzy Osbourne's public health struggles were closely tied to Parkinson's disease. The death certificate confirmed this neurodegenerative disorder was a contributing factor to his overall declining health.

Although Parkinson's itself is rarely listed as a direct cause of death, complications from the disease—such as mobility issues, falls, and the general strain on the body's systems—often exacerbate other conditions, including heart problems.

The Long Battle with Parkinson's and Spinal Trauma

Ozzy Osbourne’s health journey in the years leading up to his death was a testament to his resilience, yet it was also marked by profound physical challenges. His public announcement of his Parkinson's diagnosis in 2020 followed an initial diagnosis of a genetic form of the disease, Parkin 2, back in 2003.

The battle intensified following a severe fall he suffered in 2019. This accident aggravated a previous injury from a 2003 quad-bike crash, necessitating multiple complex spinal surgeries.

These surgeries, including a major procedure in 2023, were aimed at correcting neck and spine issues, but they left him with significant mobility problems and constant pain.

His health issues forced the cancellation of his highly anticipated farewell tour dates, including an appearance at the Power Trip festival, as he struggled to regain the physical strength required for touring.

Despite the physical toll, Osbourne remained defiant and creative, releasing new music and often appearing in public with his wife, Sharon Osbourne, even just days before his passing, when he reportedly gave a final performance.

5. The Family’s Final Statement and Legacy

Following his death on July 22, 2025, the Osbourne family released a poignant and heartbreaking statement, confirming the loss of the legendary musician.

The statement, often shared by his wife Sharon and children, read: "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 family emphasized that he died peacefully, surrounded by love, reflecting a life lived to the fullest, despite its many excesses and challenges.

Ozzy Osbourne’s legacy transcends his health battles. He is credited as one of the chief architects of heavy metal, first with Black Sabbath, whose dark, sludgy sound defined the genre, and later as a solo artist with hits like "Crazy Train" and "Bark at the Moon."

His openness about his struggles with substance abuse, mental health, and later, Parkinson's disease, made him an unlikely but powerful advocate for resilience and honesty in the face of adversity.

The outpouring of grief from fellow musicians, fans, and the media confirmed his status as a true rock and roll titan whose influence will continue to resonate for generations. His life was a wild, loud, and ultimately triumphant journey from a working-class background in Birmingham to global superstardom.
