(NewsNation) — Chevy Chase, 83, is opening up about how his heart failure led to him losing his memory.
In the upcoming CNN documentary “I’m Chevy Chase and You’re Not,” the comedian and his family address several controversies from his career, though he said he does not remember them.
His daughter, Caley Chase, said that he doesn’t recall any of the incidents because he “came back from the dead,” bringing up her father’s 2021 heart failure, which left Chevy Chase in the hospital for five weeks, according to People magazine.
“Well, I mean, he’s 80-something and has basically come back from the dead,” Caley Chase said. “Oh my God, he had heart failure. Have they talked about that at all? It’s so hard to talk about.”
His wife, Jayni Chase, revealed that the “Saturday Night Live” alum had cardiomyopathy.

“Something was wrong, and he couldn’t explain to me what was wrong. So, we go to the ER. His heart stops,” said Jayni Chase, who’s been married to “The National Lampoon” star since 1982. “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.”
Chevy Chase: Docs say memory loss tied to heart failure
Chevy Chase reveals that doctors told him that issues with his memory are most likely because of cardiomyopathy.
“According to the doctors, my memory would be shot from it, and that’s what’s happened here,” he said in the documentary, premiering on New Year’s Day.
The actor from “Community” said that he plays cards and chess to better his “cognitive disability.”
“Heart failure is what it is,” he said. “I’m fine now. It’s just that it affects your memory, and the doctors have told me that, so I have to be reminded of things.”
