Neil Sedaka's cause of death revealed after legendary singer died at 86

The legendary singer-songwriter died from atherosclerotic cardiovascular disease, with kidney failure listed as a contributing factor, according to a death certificate obtained by Fox News Digital.

"Our family is devastated by the sudden passing of our beloved husband, father and grandfather," his family said in a statement to Fox News Digital. "A true rock and roll legend, an inspiration to millions, but most importantly, at least to those of us who were lucky enough to know him, an incredible human being who will be deeply missed."

Sedaka died after being rushed to the hospital on the morning of Feb. 27.

West Hollywood Sheriff's Station personnel told Fox News Digital that deputies responded around 8 a.m., "regarding a medical request and a patient male adult was transported to a local hospital."

Sedaka first rose to fame in the 1950s and '60s, with hits such as "Oh Carol," "Breaking Up Is Hard to Do" and "Next Door to an Angel," and is known as one of the original creators of the "Brill Building" sound, a sub-genre of pop music.

"It had been like Elvis coming up and giving us the chance to release his records," John was quoted as saying at the time, according to the website. "We couldn't believe our luck."

He recorded five albums from 1972 to 1976. They included hits "Standing on the Inside," "That's Where the Music Takes Me" and "Our Last Song Together," about his breakup with Greenfield, with whom he began writing songs when Sedaka was only 13 and Greenfield 16.

In 2016, Sedaka released his 22nd studio album, "I Do It For Applause," which he called "the culmination of sixty-four years of writing."

"This is a gift I was born with," he said on his website. "My main objective is to always top the last collection, raise the bar and reinvent Neil Sedaka."
