DAPT guided by platelet function tests or genotyping after PCI: pros and cons

Introduction The importance of personalised medicine has been increasingly recognised over the last decade, with promises of optimising outcomes and minimising the risk of adverse events. This is also the case when dealing with tools to guide the selection and duration of dual antiplatelet therapy (DAPT) in patients undergoing percutaneous coronary intervention (PCI), including platelet function testing and genotyping. Guided DAPT has not been routinely adopted in clinical practice due to costs, logistical challenges, and conflicting evidence. While these approaches have shown promise in reducing the risk of adverse cardiovascular events, their clinical utility and cost-effectiveness remain to be established.##...
