‘He returned from the brink’: The comedy legend endured eight days in a coma during the pandemic.

The famed comedian suffered a “potentially fatal” heart failure that resulted in him being put into an induced coma in 2021, per details from a new film about the comedy star.

As documented in I’m Chevy Chase and You’re Not, the legend of movies such as Caddyshack and the National Lampoon series, who emceed the Oscars twice, spent a total of five full weeks in the hospital.

“There was a problem, and he couldn’t explain to me what was wrong. So, we go to the ER. His heart gave out. During those years he was drinking, he developed cardiomyopathy; which is when the heart muscles get weaker, and they are unable to pump as much blood through the body with each beat.”

Physicians subsequently induced him into a state of unconsciousness for over a week, before cautioning his child, his daughter: “We might not get him back. We don’t know how present he’ll be. You must prepare for the worst.”

“When he woke up, all he could do was use his voice,” she added. “He has basically come back from the dead.”

He himself has revealed that he has suffered cognitive issues since his medical ordeal, and in the documentary he cannot remember some of his past professional and personal disputes, including a physical altercation with Bill Murray in a Saturday Night Live green room.

He expressed he was “upset” by his omission from the milestone special of SNL recently, at which he was in the audience but not participating.

“To be frank, it was disappointing,” he said. “This is probably the first time I’m saying it. But I thought that I should have been on the stage too with all the other actors. When co-stars Garrett and Laraine Newman went on the stage, I was puzzled as to why I was not. There was no invitation. Why was I left aside?”

The 82-year-old, nearly lost his life in 1980 when he was subjected to an electrical shock on the set of Modern Problems, an accident which triggered a period of severe depression.
