Chicago Police Superintendent Garry McCarthy was released from Northwestern Memorial Hospital on Saturday after undergoing a medical procedure to unblock his arteries this week.
McCarthy “is doing very well, resting comfortably at home and looking forward to being back on patrol very soon,” Chicago Police Department spokesman Adam Collins said in a two-sentence statement issued this afternoon.
The department has said little beyond the fact that McCarthy, 55, took himself to the hospital early Thursday morning and was expected to remain there for several days after undergoing “a common procedure to address blockage in his arteries,” according to a statement issued Thursday.
“The procedure went well,” the statement said.
In an interview on Thursday, Collins said McCarthy did not suffer a heart attack but did not give any further details about the procedure..
A police source confirmed that McCarthy had angioplasty after it was determined one artery was completely blocked and another was 80 percent blocked. He was expected to have a full recovery.
Northwestern Memorial Hospital later confirmed McCarthy was a patient but referred all other questions to Collins.
McCarthy’s heart scare wasn’t the first time he had been hospitalized during his time in Chicago. McCarthy, who played linebacker on a NYPD football squad, underwent back surgery last year.
