A coronary artery calcium (CAC) scan revealing a high score can be unsettling, and the first question most patients ask is what is the treatment for a high calcium score. Understanding what is the treatment for a high calcium score requires knowing that the calcium already present in your arteries cannot be removed, but aggressive treatment can dramatically reduce your risk of a heart attack or stroke by stabilizing plaques and slowing further buildup.
A coronary calcium score measures the amount of calcified plaque in the coronary arteries using a CT scan. The score, measured in Agatston units, provides a snapshot of atherosclerosis burden. According to the American Heart Association, a score of zero indicates no detectable calcified plaque, 1-99 is mild, 100-399 is moderate, and 400 or higher is severe. The higher the score, the greater the statistical risk of a cardiac event within the next 5 to 10 years. For more health conditions and related topics, visit our conditions guide.
What a High Calcium Score Really Means
Before discussing treatment, it helps to understand what a high calcium score represents. Coronary artery calcium is a marker of atherosclerosis, the buildup of cholesterol-laden plaque in the walls of the arteries that supply blood to the heart. Over time, some of this plaque calcifies, and the calcium score reflects the total volume and density of this calcified plaque.
Key points about calcium scores:
- The score does not measure soft (non-calcified) plaque, which is actually more prone to rupture and cause heart attacks.
- A high score confirms the presence of significant atherosclerosis but does not indicate whether arteries are currently blocked.
- The score is most useful as a risk-stratification tool, helping doctors decide how aggressively to manage cardiovascular risk factors.
- According to the NIH, the calcium score is one of the strongest predictors of future cardiovascular events, independent of traditional risk factors.
The Mayo Clinic explains that a calcium score above 100 places a patient in a higher risk category, and a score above 400 is associated with a substantially elevated risk of heart attack or stroke within the next decade.
Medication-Based Treatments
When a high calcium score is detected, medication therapy becomes a cornerstone of treatment. The goal is not to remove existing calcium but to stabilize plaques, lower cholesterol, reduce inflammation, and prevent blood clots.
Statins
Statin therapy is the most commonly prescribed treatment after a high calcium score. Statins lower LDL (bad) cholesterol, reduce arterial inflammation, and stabilize existing plaques to make them less likely to rupture. According to the American College of Cardiology, a calcium score above 100 is often considered sufficient justification for starting statin therapy, even in patients who might not otherwise meet traditional prescribing criteria based on cholesterol levels alone.
Common statins include atorvastatin (Lipitor), rosuvastatin (Crestor), and simvastatin (Zocor). The target is typically an LDL cholesterol level below 100 mg/dL, with some guidelines recommending below 70 mg/dL for patients with very high calcium scores or additional risk factors.
Importantly, research published in PubMed shows that statin therapy may actually increase calcium scores over time. This counterintuitive finding occurs because statins stabilize plaques by calcifying their soft, vulnerable components, which is actually a protective process. A rising calcium score on statins does not mean treatment is failing.
Aspirin
Low-dose aspirin (81 mg daily) may be recommended for patients with high calcium scores who are at elevated risk of heart attack. Aspirin reduces the tendency of blood to clot, which can prevent a heart attack if a plaque does rupture. However, aspirin also increases bleeding risk, so the decision to prescribe it is individualized. The USPSTF recommends discussing the risks and benefits with your doctor.
Blood Pressure Medications
Controlling blood pressure is critical in patients with atherosclerosis. High blood pressure places additional stress on arterial walls, accelerating plaque progression. ACE inhibitors, ARBs, calcium channel blockers, and other antihypertensives may be prescribed to achieve a target blood pressure below 130/80 mmHg, as recommended by the American Heart Association.
Additional Cholesterol-Lowering Agents
If statins alone do not achieve target LDL levels, or if a patient cannot tolerate statins, additional medications may be added:
- Ezetimibe (Zetia): Reduces cholesterol absorption in the intestine
- PCSK9 inhibitors (Repatha, Praluent): Injectable medications that can dramatically lower LDL cholesterol by 50 to 60 percent
- Bempedoic acid (Nexletol): A newer option for patients who cannot tolerate statins
- Icosapent ethyl (Vascepa): A prescription omega-3 fatty acid that reduces cardiovascular risk in patients with elevated triglycerides
Lifestyle Modifications
Lifestyle changes are a fundamental component of treatment for a high calcium score and should accompany any medication therapy:
Heart-Healthy Diet
The Cleveland Clinic recommends a diet that emphasizes:
- Fruits, vegetables, whole grains, and legumes
- Lean proteins, particularly fish rich in omega-3 fatty acids
- Healthy fats from olive oil, nuts, and avocados
- Limited saturated fat (less than 7 percent of total calories)
- Minimal trans fats, processed foods, and added sugars
- Reduced sodium intake (less than 2,300 mg daily, ideally less than 1,500 mg)
The Mediterranean and DASH diets have the strongest evidence for cardiovascular benefit and are often recommended for patients with high calcium scores.
Regular Exercise
Physical activity improves cardiovascular health, lowers blood pressure, raises HDL (good) cholesterol, and helps manage weight. The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, cycling, or swimming. Patients with very high calcium scores or symptoms like chest pain should consult their doctor before starting a new exercise program, as stress testing may be recommended first.
Smoking Cessation
Smoking is one of the most powerful accelerators of atherosclerosis. Quitting smoking can reduce cardiovascular risk by 50 percent within the first year. If you smoke and have a high calcium score, cessation should be the top priority.
Weight Management
Maintaining a healthy weight reduces the burden on the cardiovascular system. Even modest weight loss of 5 to 10 percent of body weight can significantly improve cholesterol levels, blood pressure, and blood sugar.
Stress Management
Chronic stress contributes to inflammation and cardiovascular risk. Regular stress management through exercise, meditation, adequate sleep, and social connection supports heart health.
Additional Testing After a High Calcium Score
Depending on the score and symptoms, your doctor may recommend further evaluation:
- Stress test: An exercise or pharmacologic stress test evaluates whether the coronary arteries can deliver adequate blood flow during increased demand. This helps determine if significant blockages are present.
- CT coronary angiography (CCTA): This more detailed scan can visualize both calcified and non-calcified plaque and identify significant narrowing of the coronary arteries.
- Cardiac catheterization: If stress testing or CCTA reveals significant blockages, invasive angiography may be performed to assess the need for stenting or bypass surgery.
- Advanced lipid testing: Tests like LDL particle number, lipoprotein(a), and apolipoprotein B provide more detailed cardiovascular risk information beyond standard cholesterol panels.
Can You Reverse a High Calcium Score?
Once calcium is deposited in the coronary arteries, it does not go away with current treatments. Calcium scores either remain stable or increase over time. However, this does not mean treatment is futile. The NIH emphasizes that the rate of calcium score progression is more important than the absolute number. Aggressive treatment with statins and lifestyle changes can significantly slow the rate of progression, and research shows that slowing progression translates to reduced cardiovascular events.
The focus should not be on reversing the score but on preventing its consequences: heart attack, stroke, and cardiovascular death. Patients who aggressively manage their risk factors after discovering a high calcium score often achieve better outcomes than those with lower scores who ignore their health.
Frequently Asked Questions
Should I get a repeat calcium score scan?
Routine repeat calcium scoring is generally not recommended for treatment monitoring because scores tend to increase even with effective treatment (particularly with statin use). The initial scan serves its purpose as a risk-stratification tool. Some doctors may repeat the scan every 3 to 5 years to assess the rate of progression, but this practice varies. Treatment effectiveness is better monitored through cholesterol levels, blood pressure, and other clinical markers.
What is a normal calcium score for my age?
Calcium scores naturally increase with age. Percentile rankings compare your score to others of your age, sex, and ethnicity. A score of zero is optimal at any age. For reference, the median score for a 55-year-old man is approximately 50 to 100, while for a 55-year-old woman it is significantly lower. Your doctor can provide age-adjusted percentile data to put your score in context.
Does diet affect my calcium score?
Dietary calcium intake (from food or supplements) does not directly increase coronary artery calcium scores. Coronary calcification results from atherosclerotic plaque development, not from dietary calcium. However, a heart-healthy diet can slow atherosclerosis progression, and the USDA dietary guidelines support consuming adequate calcium for bone health without concern about coronary calcification.
Is surgery needed for a high calcium score?
A high calcium score alone does not indicate a need for surgery or stenting. Interventional procedures are reserved for patients with documented significant blockages causing symptoms (like chest pain) or shown to be dangerous on stress testing. Many patients with high calcium scores are effectively managed with medications and lifestyle changes alone. Surgery addresses blockages, not calcium deposits themselves.
Key Takeaway
Understanding what is the treatment for a high calcium score comes down to aggressive management of cardiovascular risk factors rather than attempting to remove the calcium itself. The combination of statin therapy, blood pressure control, aspirin when appropriate, a heart-healthy diet, regular exercise, and smoking cessation can dramatically reduce the risk of heart attack and stroke even in the presence of significant coronary calcification. A high calcium score is not a death sentence but rather an early warning that empowers you to take action before a cardiac event occurs.
