This variability affects clinical outcome when clopidogrel is administered in patients with acute coronary syndrome (ACS). Catecholamines, released during ACS, contribute to platelet aggregation through platelet \u03b12A- (\u03b12A-AR) and \u03b22-adrenergic receptor (\u03b22-AR) stimulation. It was the objective of this study to assess the potential influence of \u03b12A-AR and \u03b22-AR gene polymorphisms on platelet reactivity after dual antiplatelet therapy with aspirin and clopidogrel in ACS. We screened 641 ACS patients for 6.3\/6.7 kb \u03b12A-AR polymorphism, and for Arg16Gly and Gln27Glu \u03b22-AR polymorphism. After 600 mg clopidogrel, we assessed ADP 10 \u03bcmol-induced platelet aggregation (ADP-Ag) and vasoactive stimulated phosphoprotein (VASP). All single nucleotide polymorphisms were in Hardy-Weinberg equilibrium. A slight though negligible association was found between 6.3 kb allele of \u03b12A-AR with platelet reactivity ADPAg induced (beta: \u20132.91 [-5.68;-0.14], p=0.04). A borderline not significant reduction in PRI VASP was observed in 6.3 kb \u03b12A-AR carriers (beta: \u20133.81 [-0.09;7.72], p=0.06). No significant effect on platelet parameters was observed for the other tested polymorphisms. Common \u03b12A- and \u03b22-adrenergic receptor polymorphisms do not show any major impact on residual platelet reactivity in non-ST-elevation ACS when a dual antiplatelet therapy with 250 mg aspirin and 600 mg clopidogrel is administered.<\/jats:p>","DOI":"10.1160\/th09-06-0355","type":"journal-article","created":{"date-parts":[[2010,2,4]],"date-time":"2010-02-04T13:13:41Z","timestamp":1265289221000},"page":"774-779","source":"Crossref","is-referenced-by-count":8,"title":["Adrenergic receptor polymorphisms and platelet reactivity after treatment with dual antiplatelet therapy with aspirin and clopidogrel in acute coronary syndrome"],"prefix":"10.1160","volume":"103","author":[{"given":"Thomas","family":"Cuisset","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michalis","family":"Hamilos","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leen","family":"Delrue","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Corinne","family":"Frere","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katia","family":"Verhamme","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jozef","family":"Bartunek","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noemie","family":"Saut","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean Louis","family":"Bonnet","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Eijgelsheim","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William","family":"Wijns","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marie-Christine","family":"Alessi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emanuele","family":"Barbato","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2017,11,22]]},"container-title":["Thrombosis and Haemostasis"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1160\/TH09-06-0355.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,3,21]],"date-time":"2018-03-21T11:18:43Z","timestamp":1521631123000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1160\/TH09-06-0355"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010]]},"references-count":0,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2017,11,22]]},"published-print":{"date-parts":[[2010]]}},"URL":"https:\/\/doi.org\/10.1160\/th09-06-0355","relation":{},"ISSN":["0340-6245","2567-689X"],"issn-type":[{"value":"0340-6245","type":"print"},{"value":"2567-689X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010]]}}}
