Palestinian Authority Prime Minister Salam Fayyad suffered a heart attack on Sunday while in the United States to attend his son's graduation. On Monday, a hospital spokesman reported his condition as "good."
The heart attack occurred after he was admitted to the Seton Medical Center in Austin, Texas, with severe chest pain. Doctors performed a heart catheterization to open a blocked coronary artery.
Fayyad's spokesman Jamal Zakout said doctors expect to discharge Fayyad in two days.
Israeli Prime Minister Benjamin Netanyahu, in Washington on an official visit since Friday, issued a statement wishing Fayyad a speedy recovery.
Fayyad replaced Hamas chief Ismail Haniyeh as prime minister following a bloody military coup in June 2007 in which Hamas wrested control of the Gaza Strip from the Palestinian Authority's Fatah forces. Days after the coup, Abbas dissolved the three-month-old unity coalition and formed an emergency government.
Last month, Fatah and Hamas -- under Egypt's patronage -- formed another unity government. Abbas reportedly wants Fayyad to remain prime minister because he is well liked by Westerners. Both Fayyad and Abbas served with the late PLO chairman Yasser Arafat.
