Abstract:
Objective:To observe the correlation of platelet activation and the inflammatory factors in patients with coronary heart disease (CHD).Methods:A total of 150 patients with CHD were divided into three groups according to the guideline of ACC/AHA:Stable angina pectoris (SAP) group (n=47,aspirin 100 mg/d); Unstable angina pectoris(UAP) group (n=50,aspirin 100 mg/d+Dalteparin 5000 U Q12 h); Acute myocardial infarction (AMI) group (n=53,aspirin 100 mg/d+Dalteparin 5000 U Q12 h+Plavix 75 mg/d).53 healthy adults served as the Control group.The fast blood sugar,lipid,platelet count,platelet aggregation of plasma,fibrinogen,high sensitivity C reactive protein (hs-CRP) of plasma,and 11-dehydro thromboxane B_2 (11-DH-TXB_2) of urine were detected upon patients' admission.Results:The level of plasma hs-CRP in groups of SAP,UAP and AMI(4.25±2.95 mg/l,7.61±6.11 mg/l,15.46±8.22 mg/l)were significantly higher than that in Control group(2.07±1.28 mg/l,P<0.05).The max rate of platelet aggregation induced by ADP in groups of UAP and AMI were significantly higher than that in Control and SAP groups(74.35±8.91%,73.88±8.35% vs.66.22±7.51%,68.67±6.87%,P<0.05).There were significant differences in the max rate of platelet aggregation induced by arachidonic acid (AA) and 11-DH-TXB_2 of urine in different groups (P<0.05).The level of plasma hs-CRP in all patients with CHD were significantly positively correlated with the max rate of platelet aggregation induced by ADP (r=0.473,P=0.000),AA(r=0.434,P=0.000) and 11-DH-TXB_2 of urine (r=0.554,P=0.000).Conclusion:There were significant relationship between the levels of plasma hs-CRP,11-DH-TXB_2 and the max rate of platelet aggregation,which indicating inflammation might induce platelet aggregation in CHD patients.
