BACKGROUND AND RATIONALE FOR THE STUDY
Stent thrombosis occurs in 1-2% of the pts treated by PCI with stent implantation
Usage of drug-eluting stents (DES) in the real world practice might increase risk of stent thrombosis compared to bare metal stents (BMS)
The most common management of pts with stent thrombosis is re-PCI
There is lack of scientific data describing the angiographic and clinical outcome of PCI for stent thrombosis in the contemporary DES era

AIMS OF THE OPTIMIST STUDY
TO COMPARE THE CLINICAL AND ANGIOGRAPHIC CHARACTERISTICS OF DES VS BMS THROMBOSIS
TO EVALUATE THE EFFICACY OF THROMBECTOMY DEVICES DURING PCI FOR STENT THROMBOSIS
TO ASSESS THE CLINICAL OUTCOME OF PCI FOR STENT THROMBOSIS

CONCLUSIONS
1. Urgent PCI is needed for both DES and BMS thrombosis and represents 3.6% of the urgent PCI for STEMI
2. PCI for stent thrombosis is associated with a high rate of major adverse events, especially in pts with very late thrombosis3. DES thrombosis, compared to BMS, shows different clinical features (late or very late presentation, association with anti-PLT therapy withdrawal) but similar long term outcome
4. During PCI for stent thrombosis, implantation of other stents should be avoided. Mechanical thrombectomy is feasible and should be reserved to pts without haemodynamic instability
In the contemporary DES era…
