From the Guidelines
The management plan for a patient with a coronary artery calcium score in the 50-75th percentile should focus on aggressive risk factor modification to prevent progression of atherosclerosis, with consideration of moderate to high-intensity statin therapy, lifestyle modifications, and regular follow-up. The patient's risk factors should be thoroughly assessed, and their risk should be reclassified based on the coronary artery calcium score, as recommended by the 2019 ACC/AHA guideline on the primary prevention of cardiovascular disease 1. According to the 2019 ACC/AHA guideline, a coronary artery calcium score of 100 or higher or in the 75th percentile or higher is an indication for statin therapy 1. However, for a score in the 50-75th percentile, the decision to initiate statin therapy should be based on individual risk factors and shared decision-making between the patient and clinician. Key lifestyle modifications include:
- Adopting a heart-healthy diet, such as the Mediterranean or DASH diet
- Regular aerobic exercise, aiming for 150 minutes of moderate-intensity activity weekly
- Smoking cessation
- Weight management, targeting a BMI <25
- Limiting alcohol consumption
- Blood pressure control to <130/80 mmHg
- Optimal glycemic control for diabetic patients, with an HbA1c target <7% Regular follow-up every 3-6 months is recommended to assess medication adherence and side effects, with annual lipid panels targeting LDL-C reduction of at least 30-50% from baseline, as supported by the 2023 AHA/ACC/ACCP/ASPC/NLA/PCNA guideline for the management of patients with chronic coronary disease 1. Aspirin 81mg daily may be considered, especially if other cardiovascular risk factors are present. This comprehensive approach is warranted because a CAC score in this percentile range indicates moderate atherosclerotic burden and elevated risk for future cardiovascular events, even if the patient is currently asymptomatic.

From the Research
Management Plan for Coronary Artery Calcium Score in the 50 to 75 Percentile
The management plan for a patient with a coronary artery calcium score in the 50 to 75 percentile involves several considerations, including:
- Risk assessment: The coronary artery calcium score is used to assess the patient's risk of cardiovascular events, such as heart attacks and strokes 2, 3, 4, 5, 6.
- Traditional risk factors: The patient's traditional risk factors, such as age, sex, tobacco use, systolic blood pressure, antihypertensive medication use, total and high-density lipoprotein cholesterol, and race/ethnicity, should be taken into account when developing a management plan 2, 5.
- Risk classification: The patient's risk classification can be improved by adding the coronary artery calcium score to a prediction model based on traditional risk factors 5.
- Behavioral changes: Behavioral changes, such as lifestyle modifications and therapeutic interventions, can be cost-effective based on coronary artery calcium scoring 6.
- Monitoring: The patient should be monitored regularly to assess the progression of coronary artery calcium and to adjust the management plan as needed 3, 4.
Key Considerations
Some key considerations in the management plan for a patient with a coronary artery calcium score in the 50 to 75 percentile include:
- The patient's individual risk factors and medical history should be taken into account when developing a management plan 2, 5.
- The coronary artery calcium score should be used in conjunction with traditional risk factors to assess the patient's risk of cardiovascular events 2, 3, 4, 5, 6.
- The patient should be educated on the importance of lifestyle modifications, such as a healthy diet and regular exercise, to reduce the risk of cardiovascular events 6.
- The patient should be monitored regularly to assess the progression of coronary artery calcium and to adjust the management plan as needed 3, 4.
