Efficacy of Monitoring Platelet Function by an Automated PL-12 Analyzer During the Treatment of Acute Cerebral Infarction With Antiplatelet Medicine.

ABSTRACT

METHODS: All participants were administered with oral aspirin (100 mg/d) for 7 days. Blood samples were then collected and platelet function evaluated by an automated PL-12 analyzer, TEG, and the platelet count drop method. We found that platelet counts determined by the traditional platelet drop method were significantly lower in the PL-12 sensitive group and significantly higher in the PL-12 insensitive group (P < 0.05). Furthermore, MAR measured by PL-12 was positively correlated with the MA values determined by TEG and the platelet drop method (r = 0.322, r = 0.036, respectively, P < 0.05), More importantly, the PL-12 analyzer showed the largest AUC (0.748) with a sensitivity of 87.4% and a specificity of 57.4%, indicating PL-12 analyzer using in platelet aggregation evaluation of ACI patients more credibly and accuracy. Additionally, genetic analysis showed that the polymorphic of A-allele in the PEAR1 (rs12041331) gene was significantly increased in the PL-12 sensitive group rather than in the PL-12 insensitive group (P < 0.05), suggesting the predictive value of PL-12 analyzer for the prognosis of ACI patients was superior to the other methods tested herein. Our analyses demonstrate that PL-12 analysis offer a new superior technology for monitoring antiplatelet drug efficacy and for clinical prognosis of ACI patients, which has the advantages of simplicity, speed, and automation in platelet aggregation measurement.
