What is the typical duration for dual antiplatelet therapy after a stenting procedure?

The typical duration for dual antiplatelet therapy (DAPT) after a stenting procedure is generally 12 months. This extended duration is critical in preventing thrombotic events, such as stent thrombosis, especially in patients with drug-eluting stents. During the first year after stent placement, the risk of thrombosis is significantly higher, and maintaining platelet inhibition through DAPT is essential to ensure that the stent remains patent and to reduce the risk of cardiovascular events.

The first 3 to 12 months post-stenting are particularly important because, during this time, the endothelium around the stent is healing and a protective layer forms over the stent struts. Patients who are on DAPT typically receive a combination of aspirin and a P2Y12 inhibitor (like clopidogrel) to inhibit platelet activation and aggregation. Not adhering to the recommended duration of DAPT can lead to serious complications, indicating the necessity of maintaining antiplatelet therapy for the full year as typically advised in clinical guidelines.

In specific situations such as high bleeding risk or after particular types of stents or interventional procedures, the duration may be shortened, but a 12-month course is what is often recommended for the majority of
