For two days, John Truckner believed he was battling a stubborn case of heartburn. Instead, the discomfort was the only warning he would get before suffering a massive heart attack caused by a 99% blockage in one of his heart's most critical arteries—a condition doctors say can quickly become fatal without emergency treatment.
Truckner, 62, is a retired mailman who now owns Indian River Bee Company and Summit Diner in Sebastian, Florida. Active and accustomed to long days on his feet, he had no dramatic warning signs. He wasn't doubled over in pain or clutching his chest. Just one day earlier, he had been cutting down trees and doing hard physical labor, feeling as healthy and capable as ever.
But on the morning of Jan. 29, a quiet feeling that something wasn't right led him to make one small decision that doctors believe saved his life: Instead of driving straight to work, he stopped at Orlando Health Sebastian River Hospital.
Within minutes of arriving, emergency staff told him he was having a massive heart attack.
"It all went from something I thought was simple heartburn to a life-threatening emergency in a matter of minutes," Truckner shared with The Bright Story via email.
When doctors later told him his left anterior descending artery—often called the "widow maker" because of its high fatality risk when blocked—was 99% blocked, he struggled to process what he was hearing.
"I was honestly in complete shock," Truckner said. "Just the day before, I had been cutting down trees and doing hard labor. I felt strong, capable and didn't have any warning signs beyond what I thought was simple heartburn.
"It really hit me how close I had been to something far more serious—something that could have changed or even ended my life."
Doctors say Truckner's experience is one they see far too often.
"It is extremely common" for people to mistake a heart attack for heartburn or indigestion, Dr. Robert Ford, emergency medical director at Orlando Health Sebastian River Hospital, told The Bright Story. "There is a lot of overlap in the symptoms. They both can cause pain in the center of the chest, squeezing, burning."
For Truckner, listening to that quiet instinct—and acting on it—made all the difference.
It Started With Two Ordinary Dinners
Just two days earlier, nothing about Truckner's life suggested he was heading toward a medical emergency.
On Thursday evening, he went out to dinner and ordered mussels. Later that night, he developed what felt like ordinary heartburn.
"I took some Tums, and when I burped, it tasted like garlic," he recalled. "It didn't seem like anything out of the ordinary, so I didn't give it much thought."
The following evening, after eating spaghetti and meatballs, the burning sensation returned.
Once again, he reached for antacids and assumed it was simply indigestion.
Still, one memory lingered in the back of his mind.
"I remembered a friend telling me that his dad had heartburn for a few days before suffering a heart attack," Truckner said. "That memory lingered just enough that I told my son and my fiancée, 'If I'm still feeling anything in the morning, I'm going to stop by the hospital.'"
When he woke up the next morning, the discomfort was still there.
"It still felt like heartburn," he said, "but something didn't sit right with me."
A Decision He Almost Didn't Make
Even then, Truckner nearly continued driving to work.
"Honestly, I almost didn't stop," he said. "I kept telling myself it was nothing more than severe heartburn, and I had every intention of just continuing to work like any other day."
But another thought kept interrupting him.
"What if I'm wrong?"
He found himself thinking about the people waiting for him at home.
"I thought about my family and the possibility of something happening that could leave me unable to function or be there for them."
Looking back, Truckner believes there was something greater guiding him that morning.
"I've always believed that the good Lord has a way of guiding us," he said. "Looking back, I truly believe He was nudging me in that moment—leading me to make that turn into the hospital and putting me in the hands of the right people at the right time."
Everything Changed in Minutes
The moment Truckner walked into the emergency department, events unfolded with astonishing speed.
"Three nurses came out to meet me, quickly hooked me up to monitors, and within moments told me I was having a massive heart attack," he said.
Before he had time to absorb the news, hospital staff were already preparing him for emergency treatment.
"I remember hearing them call Dr. Croft as they worked urgently around me, shaving my chest and getting everything prepped to place a stent."
Dr. Charles Croft, the cardiologist who treated Truckner, said every minute matters during a STEMI.
"A STEMI means someone is having a lack of blood supply to a section of their heart, so every minute counts," Croft said.
"The longer someone waits at home, the more heart muscle they lose. If the artery is closed and the heart isn't getting enough blood, the muscle starts dying over a period of about 12 hours.
"The smaller the heart attack, the better the long-term prognosis."
The Warning Signs Were There—but Easy to Miss
Only after the emergency was over did Truckner begin connecting the dots.
"The only consistent symptom I really had was that heartburn feeling right at the base of my sternum," he said.
He also remembered another subtle warning sign.
"The night before, my right arm just didn't feel up to doing dishes at the diner. It wasn't pain exactly—just a sense of discomfort—but even then, it didn't seem significant."
Without crushing chest pain, he never suspected a heart attack.
"I didn't have the typical warning signs people associate with a heart attack," he said. "I had what felt like heartburn."
Ford said those symptoms are more common than many people realize.
"Some overlooked symptoms include indigestion ... becoming short of breath with exertion, new fatigue," he said. "I have even seen patients feel like they are having flu-like symptoms and it ends up being a heart attack."
He explained that the "widow maker" refers to a critical blockage of the left anterior descending artery, which supplies blood to the heart's largest pumping chamber.
"There is a high risk of deadly arrhythmia leading to death, risk of cardiogenic shock and also irreversible damage that causes long-term morbidity to patients and their livelihoods," Ford said.
He praised Truckner for acting when he did.
"Mr. Truckner did a great job listening to his body," Ford said. "The intermittent symptoms he was having the days before were a warning sign, but when he came in it was absolutely critical to get him to the cath lab as emergently as possible."
A Second Chance at Life
Despite the frightening diagnosis, one emotion eventually outweighed the fear.
"I felt an incredible sense of gratitude," Truckner said. "I'm so thankful that I made the decision to stop when I did and that the team at Orlando Health Sebastian River Hospital—the ER staff and the cath lab team—were ready and able to act so quickly.
"They didn't just treat me; they saved my life."
The experience has changed nearly every part of his life.
"This experience has changed everything for me," he said.
"As a man of faith, I truly believe the Lord granted me more time—that there's still more for me to do and a purpose I need to fulfill."
He now treasures everyday moments with the people he loves.
"More than anything, it's deepened my appreciation for my family," he said. "I'm incredibly grateful for every moment I get to spend with my children, my fiancée and her children. You start to see time differently."
The ordeal also inspired lasting lifestyle changes.
"I've made real changes—paying more attention to the foods I eat and choosing options that are better for my heart."
Exercise has become part of his daily routine, whether riding a stationary bike for at least 30 minutes or taking longer bike rides outdoors.
'Don't Brush It Off'
Truckner hopes his experience encourages others to take seemingly minor symptoms seriously.
"If I could say anything to someone who's experiencing symptoms—even if they seem minor—I would tell them not to wait," he said.
"Don't brush it off the way I almost did.
"If it doesn't feel right, it probably isn't."
Ford echoed that message.
"Pay attention to your body," he said. "So many patients just have the feeling that they need to be seen when they are having a medical emergency.
"Don't second-guess it. Just come and be seen and let us help decide if you need further emergent medical care."
For Truckner, a decision that took only moments became the reason he still gets to spend time with the people he loves.
"There is absolutely nothing wrong with going to get checked out, even if it turns out to be nothing," he said. "But if it's something serious, that decision could save your life.
"I'm living proof of that."
