Dual antiplatelet therapy with aspirin and clopidogrel is standard after coronary intervention. High on-clopidogrel platelet reactivity increases ischemic event risk, prompting strategies for personalized antiplatelet therapy.
Area of Science:
- Cardiology
- Pharmacology
- Genetics
Background:
- Dual antiplatelet therapy (DAPT) with aspirin and clopidogrel is standard for preventing ischemic events post-percutaneous coronary intervention (PCI).
- Significant interindividual variability exists in patient response to clopidogrel, a key antiplatelet medication.
- Elevated on-clopidogrel platelet reactivity is linked to a higher risk of ischemic complications.
Purpose of the Study:
- To review factors influencing clopidogrel response variability.
- To discuss strategies for optimizing antiplatelet therapy effectiveness.
- To improve clinical outcomes in patients undergoing PCI and those with acute coronary syndromes (ACSs).
Main Methods:
- Literature review of clinical studies on clopidogrel therapy.
- Analysis of factors contributing to variable antiplatelet response.
- Discussion of platelet function testing and genotyping approaches.
Main Results:
- Identified clinical, demographic, and genetic factors affecting clopidogrel response.
- Demonstrated correlation between high on-clopidogrel platelet reactivity and increased ischemic risk.
- Highlighted potential for personalized medicine in antiplatelet therapy.
Conclusions:
- Tailoring antiplatelet therapy based on individual response can mitigate ischemic events.
- Platelet function testing and genotyping offer promising strategies for optimizing clopidogrel efficacy.
- Personalized antiplatelet strategies may improve clinical outcomes in high-risk cardiovascular patients.
