Genotype-guided antiplatelet therapy reduced cardiovascular events in Caribbean Hispanic patients after coronary stenting. This pharmacogenomic approach using a clinical decision support algorithm improved outcomes compared to standard care.
Area of Science:
- Pharmacogenomics
- Cardiovascular Medicine
- Clinical Decision Support Systems
Background:
- Patients undergoing percutaneous coronary intervention (PCI) resistant to clopidogrel face increased risks of major adverse cardiovascular and cerebrovascular events (MACCEs).
- Caribbean Hispanic populations are underrepresented in pharmacogenomic (PGx)-guided implementation studies.
- This study investigated genotype-guided antiplatelet therapy in this specific demographic.
Conclusions:
- The pharmacogenomic-driven CDS algorithm proved clinically useful in reducing MACCEs.
- External validation confirmed the algorithm's efficacy in post-PCI Caribbean Hispanic patients on clopidogrel.
- Genotype-guided therapy offers a promising strategy for optimizing antiplatelet treatment in specific populations.
