The death certificate of singer Neil Sedaka confirms 'atherosclerotic cardiovascular disease' as the cause of death, with kidney failure as a contributing factor. The 86-year-old died on February 27, 2026, in Los Angeles shortly after hospitalization, as previously reported.
A month after the announcement of Neil Sedaka's sudden passing, his death certificate—obtained by the California Post—reveals the cause: 'atherosclerotic cardiovascular disease.' This condition involves plaque buildup in arteries, increasing risks of heart attacks and strokes, according to the American Heart Association. Kidney failure was listed as another contributing factor.
As detailed in prior coverage, the 86-year-old legend was rushed to a Los Angeles hospital on February 27 after not feeling well and passed away the same day. His family had described the loss as devastating.
Sedaka's illustrious career included 1960s hits like 'Oh! Carol,' 'Calendar Girl,' and 'Breaking Up Is Hard to Do,' plus a 1970s comeback with 'Laughter in the Rain.' He earned five Grammy nominations, induction into the Songwriters Hall of Fame in 1983, and a Hollywood Walk of Fame star in 1978.
