West Chicago Mayor Mike Kwasman is on life support and has been unconscious since suffering a heart attack on Saturday.
Kwasman is surrounded by his family at the Central DuPage Hospital Cardiac Intensive Care Unit, according to an update from city spokeswoman Rosemary Mackey Monday night.
He is "in the fight of his life," according to Mackey.
The 65-year-old mayor was out for lunch eating pizza with friends at Pal Joey's Restaurant in West Chicago when he suffered the heart attack, said Alderman Alan Murphy.
Kwasman suffered what was described as a serious heart attack and has been unconscious since arriving at the hospital, according to Mackey's statement.
He is listed in critical condition.
"Mayor Kwasman has always fought for the city he loves so much and for all of its residents," Mackey said in an emailed statement.
Kwasman was a 5th Ward alderman before being named acting mayor of West Chicago in late 2006. He was formally elected mayor in April 2007.
"The outpouring of concern by members of the community and beyond has been overwhelming, and while greatly appreciated, the family requests they be left undistracted to focus on his care," according to the city spokeswoman's statement.
