The pleiotropic effects of antiplatelet therapies
2019
Percutaneous coronary intervention is the most often used method for coronary revascularization. Stenting restores blood perfusion to ischemic areas, but it also causes mechanical disruption of the atheromatous plaque and the nearby endothelium, stimulating the activation of platelets. In a similar way, platelets are activated by thrombin exposure in the setting of plaque rupture. The interaction between platelets, oxidative stress and inflammation is an important factor determining the extent and severity of vascular dysfunction observed in these settings. Platelets activated by the vessel trauma release inflammatory and mitogenic mediators into the vascular microenvironment, activating le…
Coronary Stent Thrombosis — Predictors and Prevention
2020
BACKGROUND: Stent thrombosis (ST) is a dreaded complication after stent implantation and is associated with a mortality between 5% and 45%. The mechanisms by which ST arises are complex. Because of the seriousness of this situation, all physicians should have at least basic knowledge of it. In this article, we present the risk factors for ST and discuss some innovative approaches to its treatment. METHODS: This review is based on pertinent articles retrieved by a selective search in PubMed, and on current international guidelines and expert recommendations. RESULTS: The frequency of ST has been markedly lowered by technical advances in coronary stenting and by the implementation of modern i…
