[Updated at 4:34 p.m. ET] Broadcast icon Dick Clark, the creator and longtime host of "American Bandstand," has died, publicist Paul Shefrin said. He was 82.

Clark suffered a heart attack while at St. John's Hospital in Santa Monica for an outpatient procedure, his publicist said. "Attempts to resuscitate were unsuccessful."

Clark suffered what was then described as "a mild stroke" in December 2004, just months after announcing he had been diagnosed with Type 2 diabetes.

That stroke forced Clark to cut back on his on-camera work, including giving up the hosting duties for the "Dick Clark's New Year's Rockin' Eve" specials. He reappeared as a co-host with Ryan Seacrest on December 31, 2005.

His "American Bandstand" work, which he began as a local TV show in Philadelphia in 1956, earned him the nickname "America's oldest living teenager." The show was picked up by ABC and broadcast nationally a year later.
