What is the recommendation for platelet function testing and genetic testing in patients undergoing stent implantation?
Although higher platelet reactivity has been associated with a greater incidence of adverse events in patients undergoing stent implantation, a strategy of adjusting antiplatelet therapy based on routine platelet function testing has not been beneficial in reducing ischemic complications.26,443 445 Similarly, a strategy of routine genetic phenotype testing has also not been beneficial and thus is not recommended.26,446 448 A more detailed discussion of these issues and current recommendations about platelet function testing and genetic testing are in 6.3.
