A stent was placed in your clogged artery and it appears that healthy blood flow has been restored. You feel better than you have in some time. But the risk of stent thrombosis (ST), a clot that can develop inside the stent, shouldnt be ignored. New antiplatelet drugs such as prasugrel (Effient) and developments in stent technology such as biodissolvable polymer coatings are helping reduce the likelihood of ST, but a Dutch study shows that about one in six patients who have one episode of ST will likely have another. The study was presented at the American College of Cardiology conference in April. Christopher Bajzer, MD, Associate Director of Vascular Intervention at Cleveland Clinic, notes that recurrent ST is an infrequent event, and the risk of developing the condition can be reduced even further by conscientious patients.
