How will changes in the AHA/ACC update to the 2013 guidelines help optimize care for patients with ASCVD? Try part 2 of our 3-part quiz and find out.
1. Which of the above would be the next appropriate therapeutic step for a patient aged 50 years who recently had a second heart attack, has hypertension, and is found to have a nonfasting LDL-C of 100 mg/dL on high-intensity statin therapy plus ezetimibe after >3 months of therapy?
Answer: D. Consider initiating a PCSK9i after a discussion with the patient. This very high-risk ASCVD patient warrants consideration of the tighter LDL-C control offered by a PCSK9i but only after a discussion that includes consideration of the potential benefit, safety, and cost of treatment.
Of note, given the patient’s premature coronary artery disease and the fact that the untreated LDL-C may have been >200 mg/dL, a diagnosis of familial hypercholesterolemia should be entertained.
2. Which one of the above is NOT considered considered a risk-enhancing factor under the 2018 AHA/ACC guidelines?
3. What would be the next most appropriate step in management for a patient aged 60 years with LDL-C 90 mg/dL and an estimated 10-year ASCVD risk of 10%, in whom the decision about statin therapy is uncertain?
Answer: A. Discuss obtaining CAC score to refine risk. If a decision about statin therapy is uncertain in a patient at intermediate ASCVD risk a review of risk-enhancing factors and measuring CAC may be appropriate. Per the 2018 AHA/ACC guidelines, if CAC is: ≥100, then a high-intensity statin is recommended; 1-99, then consideration of a moderate-intensity statin is recommended; if CAC = 0 then the guidelines advise against statin therapy unless the patient smokes tobacco cigarettes, has diabetes, or carries a family history of premature ASCVD.
