‘He has come back from the dead’: The comedy legend endured eight days in a medically induced coma during the health crisis.

The famed comedian experienced a “potentially fatal” heart failure that resulted in him being put into an medically induced coma in 2021, per details from a new documentary project about the entertainment icon.

Featured in I’m Chevy Chase and You’re Not, the legend of films such as Caddyshack and the National Lampoon series, who emceed the Oscars on two occasions, was hospitalized for five weeks in the hospital.

“Something was wrong, and he was unable to describe to me what was wrong. So, we went to the ER. His heart stopped. During those years he was drinking, he got cardiomyopathy; when the heart muscles get weaker, and they can’t pump as much blood out with each beat.”

Medical professionals then put him into a state of unconsciousness for over a week, before advising his daughter, his daughter: “His return is uncertain. We are unsure how present he’ll be. You must prepare for the worst.”

“After regaining consciousness, all he could do was use his voice,” she added. “He has basically come back from the dead.”

He himself has stated that he has suffered recall difficulties since his medical ordeal, and in the film he fails to recall some of his past professional and personal controversies, including a fistfight with Bill Murray in a Saturday Night Live green room.

He expressed he was “upset” by his omission from the 50th-anniversary show of SNL earlier this year, at which he was in the audience but not on stage.

“Well, it was kind of upsetting actually,” he said. “I'm only now voicing this. But I thought that I should have been on the stage too with all the other actors. When co-stars Garrett Morris and Laraine took the stage, I was curious as to why I didn’t. I wasn't invited. Why was I left aside?”

Now 82, Chase, came close to death in 1980 when he was shocked by electricity on the set of Modern Problems, an incident which precipitated a period of clinical depression.
