Your Coronary Artery Calcium (CAC) score can be lowered by lifestyle changes, medications, and managing risk factors effectively.
Understanding the CAC Score and Its Importance
The Coronary Artery Calcium (CAC) score is a crucial marker used to assess the extent of calcified plaque in the coronary arteries. This plaque buildup is a sign of atherosclerosis, which can lead to heart attacks and other cardiovascular events. A higher CAC score indicates more calcium deposits and a greater risk of heart disease. Doctors often use this score to guide preventive strategies, tailor treatments, and evaluate overall cardiovascular risk.
The CAC score is derived from a specialized CT scan that detects calcium deposits in the coronary arteries. Scores range from zero to several thousand, with zero indicating no detectable calcium and very low risk, while higher numbers represent increasing plaque burden and heart disease risk.
Can You Lower Your CAC Score? The Science Behind It
Many people wonder if the CAC score is set in stone or if it can be improved. The straightforward answer: while you cannot completely reverse existing calcium deposits, you can slow their progression and improve your overall cardiovascular health, effectively lowering the impact of your CAC score on your future risk.
Calcium deposits in arteries are permanent markers of past damage. However, aggressive management of risk factors—such as cholesterol, blood pressure, smoking cessation, diabetes control, and diet—can stabilize plaques and prevent new calcification from forming. This reduces the likelihood that existing plaques will rupture or worsen.
Medications like statins have shown mixed effects on CAC scores themselves; some studies report slight increases due to plaque stabilization (calcium can increase as soft plaques harden). Yet, these drugs dramatically reduce cardiovascular events by improving artery health. So even if the numeric CAC score doesn’t drop significantly, your actual risk does.
Lifestyle Changes That Matter Most
Lifestyle adjustments form the cornerstone of any effort to lower cardiovascular risk associated with a high CAC score:
- Diet: Emphasizing whole foods rich in antioxidants, fiber, healthy fats (like omega-3s), and low in processed sugars helps reduce inflammation and cholesterol.
- Exercise: Regular aerobic exercise improves endothelial function, reduces blood pressure, and promotes weight loss—all factors that slow plaque progression.
- Smoking Cessation: Smoking accelerates plaque buildup; quitting is one of the most effective ways to reduce further artery damage.
- Weight Management: Maintaining a healthy weight reduces strain on the heart and improves metabolic parameters.
These changes don’t erase calcium but create an environment where existing plaques are less likely to cause harm or grow.
Medications That Impact Your CAC Score Risk
Medical treatment plays a vital role alongside lifestyle changes. While no medication directly “melts away” calcium deposits, several classes reduce cardiovascular events linked to high CAC scores:
Statins
Statins lower LDL cholesterol significantly and stabilize plaques. They may cause an apparent rise in calcium scores because they convert soft plaques into more stable calcified ones—a good thing clinically. The net effect is fewer heart attacks despite stable or slightly higher CAC readings.
Aspirin
Low-dose aspirin therapy reduces blood clot formation around vulnerable plaques. This helps prevent heart attacks even if calcification remains unchanged.
Blood Pressure Medications
Drugs like ACE inhibitors or ARBs control hypertension—one of the biggest drivers of arterial damage and plaque progression.
Emerging Therapies
Newer treatments targeting inflammation (like PCSK9 inhibitors or anti-inflammatory agents) show promise in reducing overall cardiovascular risk but have yet to demonstrate clear effects on lowering CAC scores themselves.
Monitoring Progress: How Your CAC Score Changes Over Time
Tracking your CAC score over years gives insight into how well interventions work. Typically:
- Stable or slow progression: Indicates effective management.
- Rapid increase: Signals uncontrolled risk factors needing urgent attention.
Many physicians recommend repeating the scan every 5 years or sooner depending on individual risk profiles.
The Role of Inflammation in Coronary Calcium Formation
Inflammation drives the process where fatty plaques become calcified over time. Chronic inflammation injures arterial walls, encouraging calcium deposition as part of repair mechanisms gone awry.
Controlling systemic inflammation through diet (anti-inflammatory foods), exercise, stress reduction, and medications helps reduce progression rates even if existing calcium remains.
How Risk Factors Influence Your Ability to Lower Your CAC Score Impact
Several modifiable factors affect how much you can reduce your future cardiac event risk despite your current calcium burden:
| Risk Factor | Effect on Plaque Progression | Intervention Strategies |
|---|---|---|
| High LDL Cholesterol | Accelerates plaque buildup and instability. | Lipid-lowering drugs (statins), diet changes. |
| Hypertension | Increases arterial wall stress; promotes damage. | Antihypertensives, salt restriction. |
| Tobacco Use | Catalyzes inflammation and endothelial injury. | Smoking cessation programs. |
| Poor Glycemic Control (Diabetes) | Damages vessels; speeds atherosclerosis. | Blood sugar management with meds/diet. |
| Lack of Exercise | Poor circulation; worsens lipid profiles. | Regular aerobic physical activity. |
Addressing these aggressively gives you the best shot at lowering your real-world risks tied to any given CAC score.

Frequently Asked Questions
Can You Lower Your CAC Score Through Lifestyle Changes?
While you cannot completely reverse existing calcium deposits, lifestyle changes can slow their progression. Eating a diet rich in antioxidants and healthy fats, exercising regularly, and quitting smoking help improve cardiovascular health and reduce the impact of your CAC score on future risk.
Can Medications Help Lower Your CAC Score?
Medications like statins may not significantly lower the numeric CAC score, but they stabilize plaques and reduce cardiovascular events. Although calcium deposits might remain or even increase slightly, these drugs improve artery health and lower your overall heart disease risk.
Can You Lower Your CAC Score by Managing Risk Factors?
Effective management of risk factors such as high cholesterol, blood pressure, and diabetes is key to slowing CAC score progression. Controlling these factors stabilizes plaques and prevents new calcification, thereby reducing the chance of plaque rupture or worsening heart disease.
Is It Possible to Lower Your CAC Score Naturally?
Natural methods like diet improvements, increased physical activity, and smoking cessation are essential for lowering cardiovascular risk associated with a high CAC score. These changes do not erase calcium deposits but help maintain healthier arteries and prevent further plaque buildup.
How Does Understanding Your CAC Score Help You Lower It?
Knowing your CAC score helps tailor preventive strategies and treatments. By understanding your risk level, you can focus on targeted lifestyle changes and medical interventions to slow plaque progression and improve heart health, effectively lowering your future cardiovascular risk.
The Bottom Line – Can You Lower Your CAC Score?
Yes! While you can’t erase existing coronary artery calcium completely, you absolutely can influence how it affects your health going forward. Through smart lifestyle choices combined with appropriate medical therapies, you slow down plaque growth, stabilize existing deposits, reduce inflammation, and ultimately lower your chance of heart attacks or strokes.
Your CAC score is a powerful warning sign—but it’s not a life sentence. Taking control now means turning that number into motivation for smarter habits that protect your heart for decades to come.
Remember: managing cholesterol levels aggressively with statins might keep your score steady or slightly higher due to plaque stabilization but still cuts your risk substantially. Exercise regularly, eat cleanly, quit smoking if needed, control blood pressure and diabetes meticulously—and work closely with your healthcare provider for personalized care plans.
In short: Can You Lower Your CAC Score? You can’t wipe out all calcium deposits overnight—but you can absolutely lower their danger through targeted actions that keep your heart healthier for life.
