Study of correlation between C-reactive protein and coronary heart disease

Objective:Toe explore the correlation between C\|reactive protein(CRP) and coronary heart disease(CHD) and its prognostic value.Methods:The plasma CRP levels of 136 patients were determined by immune transmission turbidity method.In which 38 cases were stable angina pectoris(SAP),39 cases were unstable angina pectoris(USAP),29 cases were myocardial infarction(AMI),30 cases were normal controls.Results:(1)CRP positive rate was 67 9% in CHD patients;(2)CRP positive level increased in SAP group,but not significant difference when compared with control group;(3) The CRP positive levels of SAP and AMI group significantly increased( P 0 01) when compared with control group,but its level of AMI group more increased( P 0 05).Conclusion:The CRP positive level increase is a risk factor of CHD.Its level is positive correlation with severity extent of CHD,and it is a valuable index on predicting prognosis.
