The following question refers to Section 6.1 of the 2021 ESC CV Prevention Guidelines. The question is asked by Dr. Christian Faaborg-Andersen, answered first by UCSD cardiology fellow Dr. Harpreet Bhatia, and then by expert faculty Dr. Eugenia Gianos.
Dr. Gianos specializes in preventive cardiology, lipidology, cardiovascular imaging, and women’s heart disease; she is the director of the Women’s Heart Program at Lenox Hill Hospital and director of Cardiovascular Prevention for Northwell Health.
The CardioNerds Decipher The Guidelines Series for the 2021 ESC CV Prevention Guidelines represents a collaboration with the ACC Prevention of CVD Section, the National Lipid Association, and Preventive Cardiovascular Nurses Association.
A 70-year-old man with a history of hypertension, diabetes, hyperlipidemia, peptic ulcer disease with a prior upper GI bleed, as well as coronary artery disease presents to clinic. About one year ago he suffered an NSTEMI treated with percutaneous coronary intervention to the mid LAD. He is feeling well and able to walk 1 mile daily with no anginal symptoms. He is currently taking aspirin 81 mg daily, ticagrelor 90 mg BID, atorvastatin 40 mg daily, metoprolol 25 mg BID, lisinopril 5 mg daily, and lansoprazole 15mg daily. He has a preserved ejection fraction. His BP in clinic is 110/70 and HR is 65 bpm. His LDL is 50 mg/dL. What do you recommend for his further management?
A. Switch ticagrelor to clopidogrel, continue indefinitely
B. Stop ticagrelor, continue aspirin indefinitely
C. Continue aspirin + ticagrelor indefinitely
D. Stop ticagrelor, start rivaroxaban 2.5 mg BID
The correct answer is B – stop ticagrelor, continue aspirin indefinitely.
Twelve months of DAPT is recommended for acute coronary syndromes (Class I, LOE A). Long-term secondary prevention with dual anti-thrombotic therapy (DAPT > 12 months with a P2Y12 inhibitor and low-dose aspirin or low-dose rivaroxaban 2.5mg BID with low-dose aspirin) may be considered for patients who are at high ischemic risk without high risk of bleeding (Class IIa, LOE A). However, this patient is at increased bleeding risk (peptic ulcer disease with prior GI bleeding) and has no ischemic symptoms, and so neither would be recommended.
In summary, 12 months of DAPT is recommended after ACS. Prolonged DAPT or low-dose rivaroxaban may be considered with high ischemic risk and low bleeding risk.
