Sopranos star Aida Turturro is opening up about the health scare that nearly ended her life.

The 63-year-old actress, best known for playing Janice Soprano on HBO’s legendary mob drama, revealed that she suffered a major heart attack eight years ago after ignoring frightening symptoms she first thought might be something far less serious.

“It was a nightmare,” Turturro admitted during a candid conversation on the June 2 episode of the podcast Messy, hosted by Christina Applegate and Jamie-Lynn Sigler.

Sigler, who played Meadow Soprano on The Sopranos, listened as her former co-star described the terrifying ordeal that changed the way she looks at her health.

“Eight years ago I had a big heart thing,” Turturro said, adding that it “probably had to do with the diabetes” and the extreme stress she was under at the time.

Turturro, who also has rheumatoid arthritis, said she had been caring for her mother and dealing with a heavy emotional load when her body started sending warning signs.

But like many women, she did not immediately realize she was having a serious heart emergency.

“I could have died, but I was lucky,” she said. “It wasn’t my time.”

The actress said she had experienced chest pains two years earlier and was told it might have been a hiatal hernia, which can mimic heart attack symptoms.

So when the pain returned, she tried to convince herself she was fine.

She wasn’t.

Turturro recalled visiting a friend and ending up on the floor in pain before making a dangerous two-hour drive back to Montauk in the rain with her dog.

Her friend wanted to call an ambulance, but Turturro refused.

“I was like, yeah, I don’t feel so good,” she remembered saying after finally getting home.

That Monday, she went to see a doctor connected to her cousin, actor John Turturro. She was then sent to a cardiologist.

Tests confirmed the shocking truth: Turturro had suffered a heart attack.

Even more alarming, doctors told her that all four of her arteries were 88 to 90 percent clogged.

She needed quadruple bypass surgery.

“I could have died; I should have died then, but I didn’t,” she said. “And I’m fine.”

Turturro even joked that she was “organizing the linen closet” just one week later.

The actress said the experience taught her a hard lesson about waiting too long to take care of herself.

“You have to take care of yourself,” she said. “Don’t do nothing, don’t wait and wait and wait.”

Turturro also voiced frustration over how little women are often told about heart disease and how symptoms can look different than they do in men.

“Nobody says anything about women,” she said. “They forget to say that the symptoms for a woman in the heart world are different.”

The health scare carries an eerie connection to her Sopranos past.

James Gandolfini, who played her volatile on-screen brother Tony Soprano, died of a sudden heart attack in Rome in 2013. He was just 51.

Turturro and Gandolfini created one of the most explosive sibling relationships in TV history as Janice and Tony Soprano during the show’s groundbreaking run from 1999 to 2007.

Now, years after her own terrifying brush with death, Turturro says she feels healthier and more aware of what her body needs.

That does not mean she claims to be perfect.

“I’m not perfect with food — no way,” she said. “I love sugar.”

She joked that if someone hands her cake, she is probably going to eat it.

But for Turturro, the lesson is not about being flawless. It is about balance, moderation, and paying attention before it is too late.

“We can always do better,” she said.
