Abstract:
Objective To investigate the prevalence of aspirin resistance(AR)in the patients with metabolic syndrome and the clinical characteristics.Methods A total of 221 patients with metabolic syndrome received 200 mg of aspirin daily for 10 days and no other antiplatelet agent.The blood samples were analyzed by platelet aggregation test(pAgT)using arachidonic acid(AA).We identified aspirin resistance when arachidonic acid induced aggregation≥20%.Results 17.6%of the patients showed AR.The AR fibrinogen level was significantly higher than AS patients(2.6?0.4 vs 2.4?0.4,P=0.017).Patients who were AR had no statistically significant difference in blood pressure,age,fasting blood glucose,blood fat and BMI compared with aspirin-sensitive patients(AS).There was also no difference in sex,smoking and history of myocardial infarction or ischemic stroke between AR and AS patients.When stratified by sex,we found history of myocardial infarction was predictor for AR in male(50.0% vs 14.5%,P=0.020)and so was diastolic blood pressure higher than 85mmHg in female(34.0% vs 15.5%,P=0.043).Conclusion The AR accounts for 17.6%(39/221)of all.In this research.AR patients have higher level of fibrinogen than AS.History of myocardial infarction and higher level of diastolic blood pressure may be the predictor for AR in male and female individually.
