Ghassan Katib, a spokesman for the authority, said Fayyad experienced chest pains Sunday. Fayyad was in Austin, where his son received a degree from the University of Texas. A spokeswoman for Seton Medical Center said Fayyad was listed in good condition early Tuesday. Katib said doctors at the hospital found and corrected a blocked artery.
