Prevention of Premature Discontinuation of Dual Antiplatelet Therapy in Patients With Coronary Artery Stents
Why the study?
Does 12 months of dual antiplatelet therapy prevent stent thrombosis, myocardial infarction, and death in patients with coronary artery stents?

Implication
Adhere to 12-month DAPT post-DES and delay elective surgery 1 year; reinforces consensus on minimizing stent thrombosis.
Key Points
- Highlight the critical necessity of adhering to dual antiplatelet therapy following coronary stent placement and mitigate the risks of premature discontinuation.
- Synthesized clinical evidence and consensus guidelines regarding dual antiplatelet therapy adherence after coronary artery stent placement.
- Evaluated perioperative antiplatelet management strategies for patients with drug-eluting stents requiring surgical interventions.
- Premature cessation of dual antiplatelet therapy (aspirin plus a thienopyridine) markedly increases the incidence of stent thrombosis, myocardial infarction, and death.
- A minimum of 12 months of continuous dual antiplatelet therapy is advised after drug-eluting stent placement, supported by thorough patient and provider education.
- Elective surgical procedures should be delayed for 1 year following stent implantation, with perioperative aspirin maintenance recommended if surgery is unavoidable.
