Sources tell Action News that Fumo was having a physical performed on Wednesday when doctors found close to 90 percent blockage in one of his arteries.
He was taken to Our Lady of Bellefonte Hospital in Ashland, Kentucky where doctors will be implanting a stint into his arteries.
Fumo, 69, is currently incarcerated due to a 2009 conviction for defrauding the state Senate, a museum and a nonprofit of millions of dollars by using their staff and resources to fund his lavish lifestyle.
He had been a wealthy Democratic power broker during his 30-year state Senate career.
