Prasugrel during primary percutaneous coronary intervention: Evidence from clinical data

Primary percutaneous coronary intervention (PCI) encompassing stent implantation is a mainstay in the management of acute ST-elevation myocardial infarction (STEMI). Despite refinements in techniques and devices, peri- and post-procedural antithrombotic therapy remains pivotal to prevent early and late thrombotic events, without unduly increasing bleeding risk. Concomitant dual antiplatelet therapy with aspirin and clopidogrel has been considered until recently the standard of care in terms of oral antiplatelet agents. However, most recently a novel and more potent thienopyridine, prasugrel, has been tested in randomized trials including patients with STEMI, and subsequently approved for clinical practice in Europe and North America. Despite its potent antithrombotic effect, prasugrel also carries a statistically significant increase in the risk of bleeding, especially in the elderly, those with low body weight, and previous stroke or transient ischemic attack. Thus, the use of prasugrel, as well as that of clopidogrel or ticagrelor, should best be individualized to maximize clinical benefits and minimize hazards. © 2012 Bentham Science Publishers.
