Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor is standard of care following percutaneous coronary intervention (PCI), however, contemporary practice continues to rely heavily on one-size-fits-all antiplatelet strategies, despite well-established interpatient variability in platelet response and clinical risk. A major contributor to this variability is genetic polymorphism of the CYP2C19 enzyme, which governs clopidogrel activation. Approximately one-third of patients undergoing PCI carry loss of function CYP2C19 alleles, placing them at increased risk for high on treatment platelet reactivity and ischemic complications when treated with clopidogrel. Conversely, more potent P2Y12 inhibitors provide consistent platelet inhibition across genotypes but are associated with higher bleeding risk, particularly in patients who would otherwise respond adequately to clopidogrel. Bleeding avoidance is as critical as ischemic prevention in optimizing PCI outcomes.Recent studies demonstrate that genotype-guided antiplatelet strategies can reduce ischemic events in CYP2C19 loss of function allele carriers without increasing bleeding risk, while allowing safe deescalation to clopidogrel in noncarriers. Join a multidisciplinary panel of experts to discuss the clinical challenges of DAPT in PCI, evidence for gene-guided therapy, and case-based strategies for implementing rapid genetic testing.
Accreditation StatementThe Society for Cardiovascular Angiography and Interventions (SCAI) is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide continuing medical education for physicians.
Credit DesignationSCAI designates this live activity for a maximum of 1 AMA PRA Category 1 Credits™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.
ABIM MOCSuccessful completion of this CME activity, which includes participation in the evaluation component, enables the participant to earn up to 1 medical knowledge MOC points in the American Board of Internal Medicine's (ABIM) Maintenance of Certification (MOC) program. Participants will earn MOC points equivalent to the amount of CME credits claimed for the activity. It is the CME activity provider's responsibility to submit participant completion information to ACCME for the purpose of granting ABIM MOC credit.
Successful CompletionParticipate in the live activity and complete the evaluation to obtain credit.
As a provider of continuing medical education through the Accreditation Council for Continuing Medical Education (ACCME), it is the Society’s policy to ensure balance, independence, objectivity, and scientific rigor in all its activities.Planning Process SCAI activities are developed by the SCAI planners prior to and independent of commercial support. Members of the Education Committee reviewed and approved this activity. If planners had relevant financial relationships, the agenda was peer reviewed by a member with no relevant financial relationships.Mitigation of Relevant Financial RelationshipsAll participating planners, reviewers, faculty, and staff are required to disclose to SCAI all financial relationships with ineligible companies. SCAI identifies relevant financial relationships and mitigates them before the activity begins.
Content Validation StatementSCAI accepts the following Content Validation Statements and expects all persons involved in its professional education activities to abide by these statements for clinical care recommendations.All clinical and pharmacological recommendations are based on evidence accepted within the medical profession as adequate jurisdiction for their indications and contradictions in patient care. SCAI does not promote recommendations, treatment, or manners of practicing medicine that are not within the definition of accredited continuing education or known to have risks or dangers that outweigh the benefits or known to be ineffective in the treatment of patients.All research referenced to support or justify patient care recommendations conforms to accepted standards of experimental design, data collection and analysis. SCAI actively promotes improvements in health care and NOT proprietary interests of an ineligible company. SCAI's educational content is free of marketing or sales of products or services.Faculty will not actively promote or sell products or services that serve their personal professional or financial interests during accredited education. SCAI encourages faculty to identify investigational products or off-label uses of products regulated by the U.S. Food and Drug Administration (FDA), at first mention and where appropriate in the content.
