From the Guidelines
The ASCVD risk score is not useful for secondary prevention cases, as it is specifically designed for primary prevention, and secondary prevention strategies should be implemented regardless of risk score. For patients who already have atherosclerotic cardiovascular disease (such as prior heart attack, stroke, coronary artery disease, or peripheral artery disease), they are automatically considered high-risk and typically require aggressive risk factor modification including high-intensity statin therapy, blood pressure control, diabetes management if applicable, antiplatelet therapy, and lifestyle modifications 1. The reason the ASCVD risk score doesn't apply to these patients is that it was developed using data from individuals without prior cardiovascular events, and its predictive value is only validated for primary prevention.
Secondary Prevention Strategies
Secondary prevention patients have already demonstrated their susceptibility to atherosclerotic disease and require comprehensive treatment regardless of what a risk calculator might predict. According to the 2018 AHA/ACC/AACVPR/AAPA/ABC/ACPM/ADA/AGS/APhA/ASPC/NLA/PCNA guideline, secondary prevention in patients with clinical ASCVD should include high-intensity statin therapy, with a goal of LDL-C < 70% 1.
Key Considerations
- High-intensity statin therapy is recommended for secondary prevention in individuals with clinical ASCVD 1.
- The ASCVD risk score is not necessary for secondary prevention cases, as these patients are already considered high-risk 1.
- Comprehensive treatment, including lifestyle modifications, blood pressure control, and diabetes management, is essential for secondary prevention patients 1.
Evidence-Based Recommendations
The 2018 AHA/ACC/AACVPR/AAPA/ABC/ACPM/ADA/AGS/APhA/ASPC/NLA/PCNA guideline provides evidence-based recommendations for secondary prevention in patients with clinical ASCVD, emphasizing the importance of high-intensity statin therapy and comprehensive treatment 1. The guideline also highlights the need for individualized treatment approaches, taking into account factors such as age, comorbidities, and medication tolerance 1.
Clinical Implications
In clinical practice, the ASCVD risk score should not be used to guide treatment decisions for secondary prevention patients. Instead, clinicians should focus on implementing comprehensive treatment strategies, including high-intensity statin therapy, lifestyle modifications, and management of comorbidities, to reduce the risk of recurrent cardiovascular events 1.

From the Research
ASCVD Risk Score in Secondary Prevention
The Atherosclerotic Cardiovascular Disease (ASCVD) risk score is a valuable tool in secondary prevention cases.
- The SMART2 risk score, as described in 2, provides an updated and validated tool for predicting recurrent ASCVD events in patients with established ASCVD.
- This score can help refine clinical management and allow for a more personalized approach to secondary prevention based on quantitative estimates of residual risk.
- Another study, 3, developed a risk equation (PREDICT-2°) to estimate the 5-year risk of CVD event recurrence among patients with known ASCVD, which can be used to complement existing equations for primary prevention of CVD.
Comparison with Primary Prevention
While the ASCVD risk score is typically used in primary prevention, it can also be useful in secondary prevention cases where the risk of recurrent events is high.
- A study, 4, found that certain primary prevention patients have an ASCVD risk equivalent to that of secondary prevention populations, highlighting the need for a more nuanced approach to risk assessment.
- The use of risk-enhancing factors, such as lipoprotein(a), and subclinical atherosclerosis testing, like coronary artery calcium (CAC) testing, can help refine risk assessment in both primary and secondary prevention, as described in 5.
Clinical Utility
The ASCVD risk score has significant clinical utility in secondary prevention, particularly in identifying patients at high risk of recurrent events.
- A study, 6, emphasized the importance of achieving guideline-recommended reductions in LDL-C to slow or halt disease progression in patients with ASCVD.
- The use of the ASCVD risk score, in combination with other clinical factors, can help guide treatment decisions and improve patient outcomes, as demonstrated in 2 and 3.
