Abstract:
Objective :To explore influence of serum uric acid (UA) on platelet function in patients with coronary heart disease (CHD) and influence of low dose aspirin (100mg) on serum UA level .Methods : A total of 117 CHD patients hospitalized in our hospital from Apr 2017 to Sep 2017 were selected .According to serum UA level ,they were divided into non-hyperuricemia group (n＝69) and hyperuricemia group (n＝48).They all received aspirin an-tiplatelet therapy after admission .Their arachidonic acid (AA ) induced platelet inhibition rate were detected by thrombelastography (TEG) on the seventh day after admission .The change of serum UA level after taking aspirin for three months were followed up .Results : After treatment ,AA induced platelet inhibition rate in hyperuricemia group is significantly lower than that in non-hyperuricemia group [(65.00 ± 19.39)% vs.(85.41 ± 22.83)%,P＝0.001]. Compared with the first day after admission ,there were significant rise in serum UA level in hyperuricemia group [(471.72 ± 53.46) μmol/L vs.(499.72 ± 54.98) μmol/L] and non-hyperuricemia group [ (319.43 ± 57.11) μmol/L vs.(338.46 ± 58.97) μmol/L] after taking aspirin for three months ,P＜0.05 both .Compared with non-hyperuricemia group ,there was a significant rise in serum UA level [(338.46 ± 58.97) μmol/L vs.(499.72 ± 54.98) μmol/L ,P＝0.001] in hyperu-ricemia group .Conclusion : In CHD patients complicated hyperuricemia ,their arachidonic acid induced platelet inhibition rate are significantly lower than that in non-hyperuricemia group .Small dose aspirin leads to serum UA level rise and its in-creasing amplitude in hyperuricemia group is significantly higher than that in non-hyperuricemia group .So , clinicians should monitor serum UA level of those patients in clinical work .
