One of the former stars of “American Gladiators” suffered a heart attack Wednesday, and is blaming steroids as one culprit, reports TMZ.com.

Nitro, whose real name is Dan Clark, felt chest pains while working out at a gym and then his left arm went numb, according to the report. A friend drove him to an urgent care center, where they realized he was having a heart attack and sent him by ambulance to a hospital.

“Nitro says the whole thing was a shock ’cause he’s in peak physical condition … and believes the heart attack may have been a result of the YEARS of steroid abuse from his days as a Gladiator,” the story notes. “According to Nitro, ‘roids weren’t viewed as taboo back in the AG heyday … it was just part of the culture.”

Clark starred as Nitro on “American Gladiators” from 1989-1996, and has appeared on a number of TV series including “Ellen” and “Saved by the Bell,” according to IMDb.
