Conservative talk radio show host Rush Limbaugh said Friday that tests show nothing wrong with his heart after chest pains hospitalized him earlier this week.
Limbaugh spoke at a Honolulu news conference shortly before being released from The Queen's Medical Center, where he was rushed Wednesday during a vacation. Doctors said he did not have a heart attack or heart disease.
"The pain was real, and they don't know what caused it," Limbaugh said.
Asked whether he was taking painkillers, Limbaugh said no.
His medical problems have attracted attention in the past. In 2003, he acknowledged an addiction to pain killers for severe back pain and took a five-week leave from his radio show to enter rehab.
"I don't think there's one thing wrong with the United States health system," Limbaugh said.
Caller after caller to his show Thursday sounded their well-wishes, asked to simply say "ditto" — a traditional Limbaugh catchword — so they could get on with questions and comments on social and government issues on the national talk show. Friday's show was a Best of Rush special.
Americans in a poll last month called Limbaugh America's most influential conservative voice, and more than 14 million people hear him at least once a week, making him the nation's highest-rated broadcaster.
