Ozzy Osbourne Reveals Heart Issues in Posthumous Memoir Following Farewell Concert

Ozzy Osbourne, the legendary Black Sabbath frontman, revealed in his posthumously released memoir, Last Rites, that he was grappling with serious heart problems, including an 80 percent blocked valve and arrhythmia caused by sepsis after a back operation. Despite these health challenges, including Parkinson’s disease and the risks of blood thinners, doctors deemed surgery too dangerous. Osbourne reflected candidly on his mortality, acknowledging that "death's been knocking at my door for the last six years" but expressed peace with his legacy and acceptance of his impending death. His biggest fear was losing his wife, Sharon Osbourne, whom he said he "lives for" and did not want to leave him first. Osbourne’s farewell concert, "Back to the Beginning," was a poignant final performance, which he described as a place where he felt free from his demons. The memoir, released after his death from a heart attack in July 2025, offers a raw and introspective look at his health struggles and emotional state in his final months.
