What is the management plan for a patient with a cardiac calcium score of 84?

From the Guidelines

A cardiac calcium score of 84 indicates mild coronary artery calcification and moderate cardiovascular risk, and management should focus on aggressive risk factor modification, including lifestyle changes and possibly medication therapy, with a moderate-intensity statin such as atorvastatin 10-20mg daily or rosuvastatin 5-10mg daily, as recommended by the 2019 AHA/ACC/AACVPR/AAPA/ABC/ACPM/ADA/AGS/APhA/ASPC/NLA/PCNA guideline 1. The patient should adopt a heart-healthy diet low in saturated fats and sodium, engage in regular aerobic exercise (150 minutes of moderate-intensity activity weekly), maintain healthy weight, and completely avoid tobacco.

• Medical therapy typically includes a moderate-intensity statin to lower LDL cholesterol to below 100 mg/dL.
• Aspirin 81mg daily may be considered if the patient has additional risk factors and low bleeding risk.
• Blood pressure should be controlled to below 130/80 mmHg using appropriate antihypertensives if needed.
• Diabetes, if present, should be optimally managed. The patient should undergo regular follow-up with risk factor assessment every 3-6 months initially, and a repeat calcium score may be considered in 3-5 years to assess progression, as supported by the 2019 ESC guidelines for the diagnosis and management of chronic coronary syndromes 1. This management approach is warranted because a calcium score of 84 indicates the presence of subclinical atherosclerosis, and early intervention can significantly reduce the risk of future cardiac events by stabilizing plaques and preventing further progression of coronary artery disease, as highlighted in the coronary artery calcium scoring guide for primary care physicians 1.

Management Plan for a Cardiac Calcium Score of 84

The management plan for a patient with a cardiac calcium score of 84 involves several considerations, including the assessment of coronary artery disease (CAD) risk and the potential benefits of statin therapy.

• A cardiac calcium score of 84 indicates the presence of coronary atherosclerosis, which is a risk factor for CAD 2.
• The score can be used to establish the presence and severity of coronary atherosclerosis, and to guide further evaluation and treatment 2.
• A study published in the Journal of the American College of Cardiology found that coronary artery calcium (CAC) scoring is a highly specific feature of coronary atherosclerosis, and can be used to assess risk for major cardiovascular outcomes 3.
• The use of statin therapy in patients with a cardiac calcium score of 84 may be beneficial in reducing the risk of cardiovascular events, although it may also accelerate the progression of CAC 4.
• A study published in Atherosclerosis found that statin eligible individuals with a baseline CAC score of 0 had a very low 15-year ASCVD risk, suggesting that statin therapy may be of limited benefit in this group 5.
• The clinical significance of the coronary artery calcium score has been discussed, and it is recommended to use CACS in combination with risk assessment of pretest probability using clinical information, including age, sex, and chest symptoms 6.

Considerations for Statin Therapy

• The decision to initiate statin therapy in a patient with a cardiac calcium score of 84 should be based on individual risk factors and clinical judgment 4, 5.
• The potential benefits of statin therapy in reducing cardiovascular risk should be weighed against the potential risks and side effects of treatment 4, 5.
• A study published in Cardiology in Review found that statin therapy accelerated the progression of CAC, but also reduced the risk of cardiovascular events 4.

Monitoring and Follow-up

• Patients with a cardiac calcium score of 84 should be monitored regularly for changes in their CAC score and for the development of cardiovascular events 3, 6.
• The use of noninvasive cardiac imaging, such as coronary computed tomography (CT) angiography, may be beneficial in assessing the presence and severity of CAD in patients with a cardiac calcium score of 84 6.
