If you tend to be proactive about your health, you’ve probably heard of coronary artery calcium (CAC) scans. They’re quick, relatively affordable, and widely available, leading many to ask two questions: “Is there a coronary calcium score test near me?” and “Should I get one?”
The Coronary Artery Calcium (CAC) Scan
A coronary artery calcium (CAC) scan is quick, noninvasive, requires no IV contrast, and takes only a few minutes to complete. It measures calcified plaque within the coronary arteries, the blood vessels that supply your heart muscle.
Heart disease tends to be quiet. Plaque can accumulate in the coronary arteries for decades before it ever announces itself as chest pain or shortness of breath. Because calcium develops as plaque matures, its presence tells us that atherosclerosis has already begun.
While other tests such as cholesterol and blood pressure screening assess your risk factors for heart disease, the CAC scan instead visualizes the disease process itself by quantifying plaque buildup. Because of this, current ACC/AHA cholesterol guidelines recognize the CAC scan as one of our most powerful tools for refining cardiovascular risk, particularly when a traditional risk assessment leaves the treatment decision genuinely uncertain.
Who Should Have a (CAC) Scan?
CAC scoring is most useful for adults who have no symptoms but whose overall cardiovascular risk remains uncertain. That includes people with borderline cholesterol levels, an elevated ApoB or lipoprotein(a), a family history of premature heart disease, diabetes or prediabetes, or several combined risk factors that put the decision to start a statin somewhere in a gray zone rather than an obvious yes or no.
Two people can have nearly identical LDL cholesterol, ApoB levels, blood pressure, and even similar family histories, yet have dramatically different amounts of plaque on imaging.
This isn’t theoretical; I see it regularly in practice. One patient exercised regularly, felt well, and had only mildly elevated cholesterol. Because of her strong family history, we obtained a CAC scan, which revealed a significant plaque burden. That finding changed our management. We started cholesterol-lowering therapy and intensified our prevention plan.
Another patient had remarkably similar cholesterol levels and family history, yet his CAC score was zero. In his case, it was reasonable to focus on lifestyle optimization while continuing to monitor over time.
That’s the value of advanced imaging. It moves us past population averages and toward a plan built for the person sitting across from us.
When a CAC Scan Isn’t the Right Test
A CAC scan is designed to refine cardiovascular risk in people without symptoms.
If you’re experiencing symptoms such as chest pain, shortness of breath with exertion, unexplained decreases in exercise tolerance, or other concerns for coronary artery disease, the clinical equation changes entirely. Rather than estimating future risk, we want to determine whether significant disease is already present.
In those situations, coronary CT angiography (CCTA) is often the better choice.
Advanced Coronary CT Angiography: Looking Beyond Calcium
Where a CAC scan measures calcified plaque alone, a CCTA uses IV contrast to visualize the coronary arteries directly. This allows us to evaluate both calcified and non-calcified (“soft”) plaque, as well as the degree of narrowing throughout the affected vessel. It gives us a far more complete picture of coronary artery disease than calcium scoring can offer on its own.
Several artificial intelligence (AI)-based software platforms can then extract even more information from those images. Tools such as Cleerly® and Heartflow Plaque Analysis™ quantify total plaque burden, distinguish calcified from non-calcified plaque, and identify higher-risk plaque characteristics that may not be apparent on a standard interpretation alone.
Sometimes, however, the most important question isn’t how much plaque is present. It’s whether that plaque is actually restricting blood flow to the heart muscle.
Heartflow FFR-CT estimates the physiologic significance of a coronary narrowing using the same CCTA images. Instead of characterizing plaque, it tells us whether a blockage is severe enough to impair blood flow and whether further evaluation or treatment is warranted.
Because these technologies answer different clinical questions, the best approach depends on the individual patient. Some are best served by detailed plaque characterization, while others need a physiologic read on blood flow.
At Personal Health MD, we help determine which approach is most appropriate based on your symptoms, risk factors, and clinical goals.
Looking Beyond the Arteries
Imaging tells us what has already developed. Advanced laboratory testing helps explain why, evaluating many of the biologic drivers of cardiovascular disease, including cholesterol particle burden, insulin resistance, inflammation, lipoprotein(a), and other metabolic and genetic contributors.
A CAC scan doesn’t replace cholesterol testing; it complements it. Together, advanced imaging and advanced laboratory testing allow us to develop a much more individualized prevention strategy than either could provide alone.
Blood work helps us understand the biology driving cardiovascular disease; CAC scoring tells us whether that biology has already left a mark.
What Does Your CAC Score Mean?
A CAC score reflects the amount of calcified plaque detected within your coronary arteries.
- 0: No detectable calcified plaque
- 1–99: Mild plaque burden
- 100–299: Moderate plaque burden
- 300 or higher: Extensive plaque associated with substantially increased cardiovascular risk
Scores can run well above 300, but these categories are what guide most clinical decisions.
A score of zero is reassuring, but it isn’t a lifetime guarantee. Healthy habits remain essential, particularly if you have elevated cholesterol, diabetes, tobacco exposure, excess visceral fat, insulin resistance, or a strong family history of premature cardiovascular disease.
Likewise, a higher CAC score doesn’t mean a heart attack is imminent. It tells us it’s time to get more aggressive about prevention, whether that’s cholesterol-lowering medication, blood pressure control, nutrition, exercise, weight management, sleep, smoking cessation, or other interventions tailored specifically to you.
The encouraging news is that identifying plaque early gives us an opportunity to change the trajectory of your cardiovascular health before symptoms ever develop.
Is Advanced Heart Imaging Right for You?
Not everyone needs advanced cardiovascular imaging.
With some people we can make sound treatment decisions based on their medical history, physical examination, and routine laboratory testing alone. Others benefit tremendously from additional imaging that helps clarify an otherwise ambiguous risk profile.
The skill is in matching the right test to the right patient at the right time.
At Personal Health MD, our goal isn’t simply to order more tests. It’s to use the best available tools to meaningfully improve decision-making to help our patients prevent cardiovascular disease or identify it early to optimize treatment.
Searching for a Coronary Calcium Score Test Near You?
At Personal Health MD, prevention is at the heart of everything we do. Rather than waiting for cardiovascular disease to declare itself, we use advanced laboratory testing and imaging, when appropriate, to better understand each patient’s individual risk. That allows us to identify problems early, make more informed treatment decisions, and develop a prevention strategy tailored to each patient.
If you’ve been searching for a coronary calcium score test near you or are simply wondering whether advanced heart imaging makes sense for you, we can help. Together, we’ll assess your personal cardiovascular risk, determine which tests are appropriate, and develop a prevention plan based on your unique risk profile.
