‘Baywatch’ actress Nicole Eggert shares a health update about her cancer journey with Fox News Digital at the Women’s Cancer Research Fund Gala.

Jean Smart ignored the early warning signs of her heart problems — until doctors told her the situation was critical.

The Emmy-winning actress, 74, is now revealing she underwent emergency triple-bypass surgery after brushing off what she thought was simple fatigue.

"I had gotten used to feeling a little pressure, like if I’d go up a couple of flights of stairs. But it would always just go away," Smart told Variety.

She added, "And I would always think, ‘Jean, you’re in such crappy shape.’ It didn’t ever occur to me that it might be anything other than the fact that I needed to exercise more."

Smart recalled feeling off while shooting an episode of "Hacks," where the set was on the campus of the University of California, Berkeley. The physically demanding scene included a keg stand at a frat party.

"After several takes, I was like, ‘Did you get it? Was that enough?’ I was feeling a little tired. But I didn’t think anything of it."

Despite the symptoms, Smart continued pushing through — until a sobering realization shifted her perspective.

Her husband of nearly 35 years, Richard Gilliland, died in 2021, and considering that, she decided to be more proactive about her health.

"I thought, ‘You haven't seen your cardiologist in a long time. Don't be stupid. Your kids just lost their dad!' So I left her a message, since it was after hours. I said, ‘I know I probably can't get in to see you this week, but maybe I should do a stress test or something.' Her service called back instantly and said, 'Yeah, you're going to go to the nearest emergency room right now!'"

Smart didn’t immediately rush off set. She shared that she waited until she finished wrapping a scene, and as soon as she got into her car, she told her driver, "'Flag on the play. We're not going back home. We're going to the hospital.'"

"Hacks" co-creator and co-star Paul W. Downs happened to be at the same hospital — and witnessed the moment everything changed. He told Variety, "I was there with her as she was talking to surgeons and hearing them say, ‘You can't get a stent. You have to get a triple bypass.'"

Looking back, Smart admitted the emotional weight of the experience didn’t fully hit her until after the surgery.

"I wasn't really scared until I woke up the next day, and I'm thinking about what they had to do," she said. "You start to feel so fragile."

In February 2023, she shared a health update on social media.

"February is American Heart Month – a time when the nation spotlights heart health, so it feels important to share with all of you that I am recovering from a recent successful heart procedure," the "Hacks" star wrote on Instagram. "I am fortunate to have excellent care and support from family and friends while I continue to recuperate."

The actress added, "Please listen to your body and talk to your doctor – I’m very glad I did!"
