ABSTRACT
Cardiovascular disease is the leading cause of death worldwide. Dual antiplatelet therapy (DAPT), with aspirin plus a P2Y12 inhibitor, is currently recommended as a default for patients after acute coronary syndrome (ACS) and following percutaneous coronary intervention (PCI). However, controversies arise over the role of aspirin, the optimal duration of DAPT after drug-eluting stent (DES) implantation, the choice of P2Y12 inhibitor and the variability in individual responses to antiplatelet agents. Recent data indicate that monotherapy with a P2Y12 inhibitor may have adequate anti-ischemic effects with lower bleeding risk. Additionally, discrepancies in DAPT duration recommendations and the optimal P2Y12 inhibitor, provides more uncertainty. We ask the question "does one size really fits all?" or should a more personalized strategy should be implemented.
Diseases affecting the heart and blood circulation are the leading cause of death worldwide. Treatment with drugs that prevents platelets from clumping (called antiplatelets) like aspirin plus another drug group (called P2Y12 inhibitors) like clopidogrel, ticagrelor and prasugrel, is currently recommended as a default for patients after heart attack and/or in whom coronary stents are inserted. However, it is very well documented that the response of any individual to these drugs is highly variable, and that the patients who don't respond as well to them are at increased risk of having clot events in their coronary arteries. On the other hand, people who respond to the drugs very sensitively have a higher bleeding risk. Despite these observations, there is no attempt to test the response of individuals patients to their antiplatelet drugs in routine practice. This review article looks in detail and whether the currently used strategy of "One size fits all" should be changed, given that there may well now be the chance to perform routine testing on everyone, and personalize their treatment accordingly.
