The 82-year-old longtime TV producer and host had been at St John's Hospital here after undergoing an outpatient procedure but suffered the heart attack following the procedure and died after unsuccessful attempts to resuscitate him, reported TMZ online.
Throughout his career, the small screen legend earned the nickname "America's Oldest Teenager" due to his eternally youthful appearance.
In addition to "American Bandstand" and "New Year's Rockin' Eve", Clark also served as a longtime Top 40 radio countdown host, hosted five versions of the game show "Pyramid" since 1973, and served as chairman and chief executive officer of Dick Clark Productions, which he had sold part of in his final years. Clark had a history of health problems.
He was diagnosed with Type 2 diabetes in 1994, which he kept private until 2004, the year he suffered a stroke that forced him to retire as host of "New Years' Rockin' Eve." Clark created the program in 1972 and earned a Peabody Award for his coverage.
He was only unable to host twice until his stroke. Though Ryan Seacrest has since taken over, Clark made annual appearances.
