The world of heavy metal lost its undisputed king, John Michael "Ozzy" Osbourne, on July 22, 2025. The legendary Black Sabbath frontman and solo icon, often dubbed the "Prince of Darkness," passed away at the age of 76, leaving behind a monumental legacy that spanned over five decades.

The Official Cause of Death: Acute Myocardial Infarction

The primary and immediate cause of Ozzy Osbourne’s death, as officially recorded on his death certificate, was an Acute Myocardial Infarction, commonly known as a severe heart attack. This sudden cardiac event was the final, tragic moment in a long series of health complications. A heart attack occurs when blood flow to a part of the heart is blocked, most often by a blood clot, causing heart muscle tissue to die.

It is crucial to understand that while the heart attack was the direct cause, it was a consequence of pre-existing, chronic conditions that had severely weakened his cardiovascular system and overall health. The certificate specifically listed two other major factors that contributed to the fatal event.

Chronic Conditions: The Contributing Factors to Ozzy's Passing

The life of a rock star, particularly one with Ozzy's history of substance abuse and high-octane lifestyle, inevitably takes a toll on the body. However, the two major conditions listed as contributing to his death were chronic, progressive diseases that required constant medical attention and multiple surgeries in his final years.

1. Coronary Artery Disease (CAD)

The first major contributing factor listed on the official documents was Coronary Artery Disease (CAD). This is the most common type of heart disease, where the major blood vessels that supply the heart become damaged and narrowed by plaque buildup (atherosclerosis). This narrowing restricts blood flow, making the heart muscle oxygen-deprived and significantly increasing the risk of a heart attack.

For Ozzy, his history of heavy smoking and other lifestyle factors likely accelerated the progression of CAD. The disease created the perfect storm for the fatal myocardial infarction, as his arteries were already compromised and struggling to supply blood to the heart muscle.

2. Parkinson's Disease (PRKN-2)

Perhaps the most public of his health battles was his diagnosis of Parkinson's disease, which he revealed in 2020, though he had been living with it since 2003. More specifically, Ozzy was diagnosed with PRKN-2, a rare, genetically-linked form of the disease often categorized as early-onset Parkinson's.

Parkinson's is a progressive neurological disorder that affects movement, often causing tremors, stiffness, and difficulty with balance and walking. While Parkinson's itself is not typically a direct cause of death, it severely weakens the body, making it more vulnerable to secondary complications like pneumonia, falls, and, critically, placing immense stress on the cardiovascular system.

His wife, Sharon Osbourne, often spoke about the physical toll the disease took, noting that it particularly affected his legs and mobility. The constant, chronic pain he experienced in his final years, exacerbated by a serious fall and subsequent surgeries, meant his body was in a state of continuous struggle, which would have severely complicated his recovery from any major medical event.

The Final Years: Surgeries, Pain, and The Quest for One Last Show

The period leading up to Ozzy's death was marked by a series of intense medical interventions and a relentless pursuit of health, driven by his desire to perform one final time. This era is critical to understanding the context of his passing.

  • The 2019 Fall: A major turning point was a fall he sustained in 2019, which aggravated injuries from a 2003 ATV accident. This required multiple complex spinal and neck surgeries.
  • Multiple Surgeries: Between 2019 and 2023, Ozzy underwent several major operations, including a crucial fourth surgery in 2023 to correct issues stemming from the fall. These procedures were aimed at alleviating pain and restoring mobility, but they put enormous strain on his body.
  • Constant Pain: Ozzy himself spoke candidly about spending months in "constant" pain, a struggle that predated his public Parkinson's diagnosis but was intensified by the combination of his neurological condition and spinal injuries.
  • The Farewell: Despite his failing health, he was actively preparing for a final farewell concert with Black Sabbath in his hometown of Birmingham, England, planned for May 2025. This ambition underscored his lifelong dedication to music, even as his body failed him.

The combination of severe Coronary Artery Disease, the debilitating effects of PRKN-2 Parkinson's, and the physical trauma from multiple major surgeries created a highly fragile state. When the acute myocardial infarction occurred on July 22, 2025, his body was simply too compromised to recover, leading to the confirmation of his death. The legacy of the Prince of Darkness will forever be a testament to a life lived to the absolute extreme, a life that finally succumbed to the inevitable physical toll of time and disease.
