Aims: Stent thrombosis (ST) is a major complication of percutaneous coronary interventions (PCIs). An invasive management by re-PCI is the commonly adopted treatment for ST, but data on outcome are limited.
Methods and results: We performed a 2-year multicentre registry enrolling consecutive patients with angiographically confirmed ST undergoing PCI. The primary angiographic endpoint was optimal angiographic reperfusion (TIMI 3 + blush grade 2 or 3). The primary clinical endpoints were death and major adverse coronary and cerebrovascular events (MACCEs) at 6 months. A total of 110 patients underwent 117 urgent PCI during the study. Patients with drug-eluting stent (DES) thrombosis, compared with those with bare metal stent (BMS) thrombosis, exhibited a higher rate of late or very late presentation and of anti-platelet therapy withdrawal. Optimal angiographic reperfusion was obtained in 64% of the patients. Death and MACCE rates at 6 months were 17 and 30%, respectively. Clinical outcome was similar for BMS and DES thrombosis. Very late ST, implantation of stent during PCI for ST, and failure to achieve optimal angiographic reperfusion were the independent predictors of 6-month mortality.
Conclusion: DES and BMS thromboses have different clinical features, but a similar poor outcome. Indeed, PCI for ST is associated with a low rate of reperfusion and to a high rate of death and MACCE, calling for action in order to prevent its occurrence and to improve its management.
