Pharmacogenetics of Antiplatelet Therapy
Annu Rev Pharmacol Toxicol. 2022 Aug 1. doi: 10.1146/annurev-pharmtox-051921-092701. Online ahead of print.ABSTRACTAntiplatelet therapy is used in the treatment of patients with acute coronary syndromes, stroke, and those undergoing percutaneous coronary intervention. Clopidogrel is the most widely used antiplatelet P2Y12 inhibitor in clinical practice. Genetic variation in CYP2C19 may influence its enzymatic activity, resulting in individuals who are carriers of loss-of-function CYP2C19 alleles and thus have reduced active clopidogrel metabolites, have high on-treatment platelet reactivity and increased ischemic risk.

Efficacy and Safety of De-escalation of Antiplatelet Therapy After Percutaneous Coronary Intervention in Patients With Acute Coronary Syndrome: A Meta-Analysis of Randomized Clinical Trials
Abstract: Considering that there is no definite conclusion on the efficacy and safety of switching from potent P2Y12 inhibitors to clopidogrel, we conducted a systematic review and meta-analysis of patients with acute coronary syndromes undergoing percutaneous coronary intervention and compared the efficacy and safety of de-escalation or not of antiplatelet therapy. The relevant randomized controlled trials were included by searching several databases. Net adverse clinical events were identified as the composite end point, which was defined as a composite of cardiovascular death, myocardial infarction, revascularizatio...

Comparison of short-term clinical outcomes between low-dose prasugrel and clopidogrel as part of triple antithrombotic therapy in patients requiring oral anticoagulant therapy and percutaneous coronary intervention
ConclusionsCombination of low-dose prasugrel and DOAC was associated with lower incidence of MI, ischemic stroke, and blood transfusion. Low-dose prasugrel may be feasible as part of triple therapy in patients undergoing PCI.

Comparison of Ischemic and Bleeding Events Between Short-Duration Versus Long-Duration Tirofiban Regimens in Patients With ST-Segment Elevation Myocardial Infarction Undergoing Percutaneous Coronary Intervention
Abstract: Tirofiban has been used historically as a bridge to platelet inhibition with clopidogrel in ST-segment myocardial infarction (STEMI) during percutaneous coronary intervention (PCI) to prevent stent thrombosis. However, ticagrelor and prasugrel reach similar levels of platelet inhibition at 30 minutes to that of clopidogrel at 6 hours, challenging the need for long-duration tirofiban. This 1-year, retrospective cohort study compared ischemic and bleeding outcomes of short-duration versus long-duration tirofiban regimens in patients with STEMI who received ticagrelor or prasugrel at the time of PCI. The primary...

Impact of the ABCD-GENE Score on Clopidogrel Clinical Effectiveness after PCI: A Multi-site, Real-world Investigation
The objective of this study was to validate the ability of ABCD-GENE score to predict risk for atherothrombotic events in a diverse, real-world population of clopidogrel-treated PCI patients who received clinical CYP2C19 genotyping to guide antiplatelet therapy. A total of 2341 adult patients who underwent PCI, were genotyped for CYP2C19, and received treatment with clopidogrel across four institutions were included (mean age 64±12 years, 35% female, 20% Black). The primary outcome was major atherothrombotic events, defined as the composite of all-cause death, myocardial infarction, ischemic stroke, stent thrombosis, or r...

Current status of antithrombotic therapy and in-hospital outcomes in patients with atrial fibrillation undergoing percutaneous coronary intervention in Germany
CONCLUSION: The preferred therapy after PCI in patients with AF is DAT with a NOAC and clopidogrel. In-hospital ischemic and bleeding events were rare. The recommended durations for combination therapy vary considerably.PMID:35243515 | DOI:10.1007/s00059-022-05099-6

The WOEST  2 registry : A prospective registry on antithrombotic therapy in atrial fibrillation patients undergoing percutaneous coronary intervention
CONCLUSIONS: Patients on combined oral anticoagulation and antiplatelet therapy undergoing PCI are elderly and have both a high bleeding and ischaemic risk. Over time, a NOAC plus clopidogrel became the preferred treatment. The rate of thrombotic and bleeding events was not significantly different between patients on triple or dual therapy or between those on VKAs versus NOACs.PMID:35230636 | DOI:10.1007/s12471-022-01664-0

Clinical Outcomes After Percutaneous Coronary Intervention Over Time on the Basis of CYP2C19 Polymorphisms
In conclusion, these data demonstrate a higher risk for ischemic events in patients with 2 CYP2C19 LOF alleles who are prescribed clopidogrel, seen at 3 months after PCI, that is not sustained for 12 months.

Influence of Clinically Significant Genes on Antiplatelet Effect of Clopidogrel and Clinical Outcomes in Patients with Acute Coronary Syndrome and Atrial Fibrillation
Conclusion: In our study, we determined that carriers of CYP4F2 gene polymorphisms C(Val433Met)T, PEAR1 rs41273215 C#x3e;T (CT+TT) were associated with lower safety of antithrombotic therapy in patients with ACS and AF. And, the B4GALT2 rs1061781 gene polymorphism was associated with a greater risk of insufficient efficacy of the therapy. The data obtained in our study may improve the understanding of the effect of less studied genetic markers on the efficacy and safety of antithrombotic therapy in patients with ACS and AF.Pharmacology
