Surgery after drug-eluting stent (DES) implantation may be associated with increased risk for perioperative stent thrombosis (ST). ⋯ In spite of preoperative "bridging" with a glycoprotein IIb/IIIa inhibitor, postoperative stent thrombosis can still occur in patients with prior DES undergoing surgery requiring antiplatelet medication interruption.

In the acute coronary syndrome setting, the interaction between epicardial coronary artery stenosis and microcirculation subtended by the culprit vessel is poorly understood. The purpose of the present study was to assess the immediate impact of percutaneous coronary intervention (PCI) on microvascular resistance (MR) in patients with non-ST-elevation myocardial infarction (NSTEMI). ⋯ When collateral flow is accounted for, removal of epicardial stenosis increases MR in patients with NSTEMI undergoing PCI.
