[Coronary stenting and surgery: perioperative management of antiplatelet therapy in patients undergoing surgery after coronary stent implantation].
The management of antiplatelet therapy in patients with coronary stents undergoing surgery is a growing clinical problem and often represents a matter of debate between cardiologists and surgeons. It has been estimated that about 4-8% of patients undergoing coronary stenting need to undergo surgery within the next year. Surgery represents one of the most common reasons for premature antiplatelet therapy discontinuation, which is associated with a significant increase in mortality and major adverse cardiac events, in particular stent thrombosis. ⋯ A consensus on the most appropriate antiplatelet regimen in the perioperative phase has been reached on the basis of the ischemic and hemorrhagic risk. Dual antiplatelet therapy should not be withdrawn for surgery at low bleeding risk, whereas aspirin should be continued perioperatively in the majority of surgical operations. In the event of interventions at high risk for both bleeding and ischemic events, when oral antiplatelet therapy withdrawal is required, perioperative treatment with short-acting intravenous glycoprotein IIb/IIIa inhibitors (tirofiban or eptifibatide) should be considered.

Review[Aspirin in primary prevention of cardiovascular diseases: how to balance risks and benefits].
While the use of aspirin in the secondary prevention of cardiovascular atherothrombotic disease is well established, many aspects of primary prevention are still unclear. Uncertainties mostly depend on a doubtful risk-benefit ratio, because of the low atherothrombotic risk of populations involved on the one hand, and the non-negligible bleeding risk of treatment on the other. ⋯ Based on the results of a number of clinical trials and meta-analyses, and especially considering the absolute figures of the benefit (major cardiovascular events avoided) and of the harm (major bleeding events occurred related to aspirin), the authors recommend to limit primary cardiovascular prevention with aspirin (in apparently healthy subjects with no previous cardiovascular events) to subjects with an estimated global cardiovascular risk ≥2 major cardiovascular events per 100 patients-year, as assessed by the risk score assessments proposed in the Italian "Progetto Cuore" (www.progettocuore.it). This cut-off should also be adopted for primary prevention in patients with type 2 diabetes and/or asymptomatic peripheral arterial disease.
