Former mayor Richard M. Daley will stay at Northwestern Memorial Hospital’s intensive care unit at least through mid-week to undergo further testing after he fell ill Friday while on a business trip to Scottsdale, Ariz.
Daley, 71, is alert and in good spirits, but doctors want to pin down the cause of his ailment before he leaves, said Jacquelyn Heard, a longtime aide and spokeswoman for the Katten Muchin Rosenman law firm where Daley is of counsel. "He may be here until mid-week, if not longer," Heard said.
Daley felt ill Friday afternoon during a conference he was attending with members of his firm, Heard said. He was still feeling ill and disoriented when he boarded the plane home, she said.
The former mayor's family was aware of the situation and had an ambulance waiting when his plane returned in Chicago on Friday, Heard said.
Daley's illness came the same day his nephew, Richard "R.J." Vanecko, pleaded guilty to involuntary manslaughter in the 2004 death of David Koschman. Vanecko punched Koschman during an angry early-morning encounter in the Rush Street nightlife district. Vanecko agreed to serve 60 days in jail.
A report by former U.S. Attorney Dan Webb, the special prosecutor in the Vanecko case, on whether investigations into Koschman’s death, were properly conducted could be released as soon as Monday. Daley was mayor during both investigations.
Daley has maintained a busy life in the legal, business, education and government spheres since deciding not to run for reelection in 2011 after a record 22 years as Chicago's mayor. His wife, Maggie, died in November 2011.
Daley and Maggie Daley were hospitalized at Northwestern in late December 2002 after they both passed out because of dehydration due to the flu. During his stay, doctors discovered Daley had heart arrhythmia when his heart rate shot up to 155 beats per minute while he was sleeping, and he was put on medication to control arrhythmia and high blood pressure.
Daley had been checked in to Northwestern overnight Feb. 28 to March 1, 2002 after he lost his balance and felt lightheaded at Rosebud Steakhouse, 192 E. Walton St. Doctors at the time said they believed the episode was triggered by a leg cramp brought on by exercise, but later said the arrhythmia might have been a factor.
The former mayor also was hospitalized in 2000 after he suffered vague chest pain and high blood pressure. Although he passed a battery of medical tests and no blockages were found in his coronary arteries, he was placed on blood-pressure medication at the time.
Prior to his 2000 hospitalization, Daley had not had a physical examination for a decade, his doctors said at the time.
At a Chinese New Year event on Sunday, U.S. Sen. Dick Durbin said he had left messages with the former mayor but hadn't heard back.
"I don't know how serious it is" Durbin said. "We're all pulling for him."
