As a personal trainer, NASM Corrective Exercise Specialist, and someone who has dedicated much of his life to helping others improve their health, I believed I understood fitness and heart health very well. I exercised consistently, stayed active, watched my weight, and tried to do the right things physically. Yet despite all of that, I eventually found myself preparing for quadruple bypass surgery. That experience changed my life forever.
One of the most important lessons I learned through that journey is this: you can look healthy on the outside while serious heart disease silently develops on the inside. This is exactly why a coronary artery calcium scan, often called a CAC scan, is so important. It has the potential to identify danger long before a catastrophic heart event occurs. Heart disease is often called the “silent killer” because many people have absolutely no symptoms until something major happens. Some people experience a heart attack while walking, exercising, or even sleeping. Others may feel only mild fatigue, shortness of breath, or occasional chest tightness and dismiss it as aging or stress. Unfortunately, by the time symptoms become obvious, significant blockage may already exist.
A coronary artery calcium scan is a quick, non-invasive CT scan that measures calcium buildup in the arteries of the heart. Calcium in the coronary arteries is a marker of plaque accumulation and atherosclerosis. In simple terms, the scan helps determine whether the arteries supplying blood to your heart are beginning to harden and narrow.
The beauty of this scan is that it can detect disease before major symptoms develop. In my own situation, I had a strong family history of heart disease and stroke. Looking back, genetics were speaking loudly, but like many people, I believed my lifestyle alone would protect me. What I eventually learned is something I now share with clients regularly: genetics are not destiny, but they are influence. We may not control the hand we were dealt genetically, but we absolutely can control how we respond to it.
When I learned the seriousness of my coronary disease, I made a decision that surprised many people. I trained for my quadruple bypass surgery. That statement may sound strange, but I approached surgery the same way I would prepare for a major athletic event. I focused on improving my cardiovascular conditioning safely, strengthening my body, improving my mindset, and preparing emotionally and spiritually for the challenge ahead. I understood that stronger people generally recover better. I also understood that fear alone helps no one.
What became painfully clear to me during this process was how many people are walking around completely unaware of their cardiovascular risk. Many assume that if they exercise occasionally, are not overweight, or have decent cholesterol numbers, they are safe. Unfortunately, plaque buildup can still occur even in active individuals.
This is why a calcium scan can be such a valuable tool. The scan itself takes only minutes. There are no needles, no stress test, and no recovery time. The result is usually presented as a calcium score. A score of zero is excellent and suggests little to no detectable coronary plaque. As scores rise, so does the concern regarding coronary artery disease and future cardiac risk.
For many people, the scan becomes a wake-up call.I have seen individuals completely change their lives after discovering elevated calcium scores. They begin exercising consistently, improving nutrition, reducing body fat, lowering stress, improving sleep, and following up appropriately with their physicians. In many ways, the scan provides clarity. It replaces guessing with information.
The greatest mistake many people make is waiting until symptoms force them to take action. As a trainer who works extensively with adults over 55, I constantly encourage clients to think proactively rather than reactively. We maintain our homes, service our cars, and inspect our appliances before they fail. Yet many people ignore the very organ that keeps them alive every second of every day. A coronary artery calcium scan is not about creating fear. It is about creating awareness.
Knowledge gives us the opportunity to intervene early. Exercise, strength training, improved nutrition, weight management, blood pressure control, stress reduction, and medical supervision can all dramatically improve quality of life and longevity. But we first need to know what we are dealing with. My own bypass surgery taught me something else as well: physical fitness alone is not enough. Emotional and spiritual preparedness matter greatly too. Fear can paralyze people. Some avoid testing because they are afraid of what they might discover. But ignoring reality never changes reality. In fact, early detection may provide the very opportunity that saves your life.
Today, I continue encouraging others to become proactive about their health. I want people to understand that prevention is far easier than recovery. If you are over 40, have a family history of heart disease, high cholesterol, diabetes, high blood pressure, or simply want a clearer picture of your heart health, speak with your physician about whether a coronary artery calcium scan is appropriate for you. That one simple test could provide the information that changes — and possibly saves — your life.
As I often remind my clients through my own experience, we are not determined by our genetics; we are only influenced by them, and we can change our response to that influence at any time.
