While coronary calcium scores can't be lowered, a moderate or high score is a sign that you should take measures to reduce your risk of heart disease. Work with your doctor to start preventative measures, such as medication, diet, exercise, and other heart healthy practices.

1
Take a daily aspirin to reduce your risk of heart attack or stroke. An over-the-counter aspirin may help keep your heart healthy if you have a high coronary calcium score. However, due to the risk of side effects, you should only begin a daily aspirin regimen if your doctor recommends it.
- Aspirin can help people with high blood pressure, a family history of heart disease, kidney problems, diabetes, or a history of smoking.
- Do not use aspirin if you have liver or heart failure or stomach ulcers. People under 21 should not take aspirin.
2
Take a statin if you have a coronary calcium score over 300. Your doctor may prescribe a statin, such as atorvastatin or pravastatin, to reduce your risk of a heart attack and manage your cholesterol levels. These are typically pills taken by mouth once or twice a day. Take this medication according to your doctor’s instructions.
- Side effects of statins include muscle damage, confusion, memory loss, high blood sugar, or liver damage.

Undergo a heart scan to check your coronary calcium levels. A coronary calcium scan is currently the only way to check your coronary calcium score. The radiologist will scan your heart using a CT scanner. Remove your shirt and put on a medical gown. The doctor will attach electrodes to your chest. Lie down on the table when directed. The table will move slowly into the CT scanner.^{[12]

Discuss the results with your doctor. The score indicates the likelihood that you will have a heart attack or other heart problem in the next 3-5 years. Based on the results of your scan, your doctor may adjust or change your medication. If you have a low score, you may not need further treatment.^{[14]

- A score of 0-100 means that a heart attack or stroke is unlikely in the next 3-5 years. You do not need to take any precautions.
- A score between 100-300 means that you have a high risk of developing heart disease in the next 3-5 years. Your doctor may prescribe you medication or put you on a special diet.
- Scores over 300 indicate an extremely high risk of heart disease. In most cases, your doctor will prescribe medication like statins or recommend further treatment.
5
Undergo further testing if you have a moderate to high score. If your score is over 100, your doctor may decide to do additional tests. They may do a blood test to check your cholesterol and blood sugar levels. They may also perform a stress test. These tests will determine the cause (or causes) of your risk.^{[15]

Because you are exposed to a small amount of radiation, doctors do not perform coronary calcium heart scans often. While there is no official recommendation for how often you need this, in most cases, you will not need to be retested for another 3-5 years. In some extreme cases, however, the doctor may recommend retesting within 1 year.^{[17]
