Sometimes the difference is a team so steady that fear never gets a foothold.
Pete O’Brien thought he had the flu.
He felt off that morning, his elbow aching in a way he couldn’t quite explain. So he did something he almost never does. He came home from work early. Karen, his wife, knew right then that something was wrong. Pete simply doesn’t leave early.
They drove to a local walk-in clinic expecting a quick visit, maybe a shot, and then home. Instead, a nurse practitioner ran an EKG and delivered news that stopped them cold. The reading looked bad. An ambulance was already on the way.
“I never imagined I was having a heart attack,” Pete says. “I thought it would be an hour or two at the hospital, and then they’d release me.”
That’s the last thing he remembered for five days.
When Minutes Matter
At the Mississippi Heart and Vascular Institute at FMOL Health | St. Dominic, the cath lab team moved fast. Pete was actively having a STEMI, one of the most serious kinds of heart attacks, in which a blocked artery cuts off blood flow to the heart. What Karen thought might be a quick procedure with stents became something far bigger.
That’s when she met John Calhoun, MD.
He sat down with her, explained what was happening and walked her back to Pete. Someone even carried over a computer screen to show the family exactly what the team had found. In that moment, the plan changed. Pete needed open-heart bypass surgery, and he needed it now.
Dr. Calhoun found the words that stayed with Karen ever since. “Pete’s heart was hanging on the edge of a cliff,” he said. And the team had reached out and pulled him back.
A First for the Jackson Team
Surgery began around noon. Karen and her family settled into the waiting room, expecting a long day. They had no idea how long.
Pete’s heart had been through so much that it couldn’t come off the bypass machine on its own. To carry him through, his surgical team added a small device called an Impella, which threads into the heart and takes over some of its pumping work. The left side alone wasn’t enough, so they added a second device on the right.
Pete became the first double Impella patient for the St. Dominic team.
From Friday until Monday, his chest stayed open while the two devices did the work his heart couldn’t yet manage. That Monday, surgeons went back in, cleared away blood clots and closed him up. Then, slowly and carefully, they began weaning him off the right device, then the left, waiting patiently for his heart to take over again.
It did.
The One Who Remembers Everything
Here’s what makes this story different. Pete slept through the hardest part. Karen lived every single minute of it.
“I don’t remember much,” Pete says.
“I remember everything,” Karen answers.
For five days, she sat with the weight of not knowing. She watched monitors. She waited for updates. She held a fear most can only imagine. And yet, she says, that fear never fully took hold, because of the people around her.
“They were so knowledgeable about what they do that I had no fears,” Karen says. The team kept her in the loop at every turn. Nurses explained. Doctors sat down. No one rushed her past her questions.
“We didn’t have time to get scared because they knew what they were doing,” Karen says.
That steadiness became its own kind of medicine.
Family Gathered Close
Word spread quickly. Pete’s sister came straight to the hospital and returned every day after work. His brother, a pastor, flew in from New Jersey to pray over him, then returned home to care for his own congregation. Karen’s daughter, a nurse practitioner, found coverage for her shift so she could be at her mother’s side.
Even the little ones came. Karen never imagined she’d let a child into the ICU, but Pete is his young grandsons’ whole world. So the boys came to lay eyes on him, just for a moment. When Pete finally woke up, one of his first questions was about the boys.
Love filled that waiting room. And love, it turns out, is a powerful thing to wake up to.
Waking Up to a New Chapter
When Pete came to, the world felt strange. Vivid dreams had left him confused, convinced for a while that he was somewhere else entirely. It took a few days to gather his wits.
Then his natural stubbornness kicked in, the very thing that had kept him so healthy all along.
Pete is what Karen affectionately calls a health nut. He hit the gym four days a week for cardio and weights. On a beach vacation, his idea of relaxing was climbing 100 flights of stairs for fun. Lying still in a hospital bed, tangled in tubes and beeping monitors, nearly drove him crazy.
“I’m a very active person,” he says. “I’m not used to just lying around.”
His care team met that restlessness with patience. When he pushed to do more than he should, they gently held the line. When he was ready, they got him up and walking. Day by day, he felt his strength returning.
“They really cared about what was going on and how I was doing,” Pete says.
How Close It Really Was
Karen didn’t grasp how serious things had been until Pete was already on the mend. That, she says, was a mercy.
The full truth came later, in a quiet moment months down the road. The O’Briens were asked to visit another double Impella patient and offer encouragement to a frightened family. While they were there, one of the nurses who had cared for Pete said something Karen never forgot.
“We were so worried about you, too,” the nurse admitted. “We didn’t know you’d make it.”
That’s when Karen understood just how far her husband had come. And just how much this team had given them.
Counting Tomorrows
Pete and Karen have been married 10 years. Between them, they now share a dozen grandchildren.
On their last anniversary, Karen wasn’t sure Pete would make it there at all. Today, they’re planning beach trips where the whole family gathers under one roof. They’re watching grandbabies grow. They’re savoring the ordinary days that once felt so uncertain.
Don’t Wait for a Warning
Pete’s heart attack arrived with almost no warning. A little fatigue. An aching elbow. Symptoms easy to brush off as the flu. If he had waited even a little longer, the story might have ended very differently.
That’s why Karen now shares their story with anyone who will listen.
“I tell everyone, get a heart assessment,” she says. “Don’t wait. The people who love you are counting on it.”
Their message is simple. Heart trouble doesn’t always announce itself loudly. Listen to your body. Take the small signs seriously. And when something feels off, act on it. A single decision, made in time, can give you back your tomorrows.
Pete and Karen got theirs. And they don’t intend to waste a single one.
