The Research Of Correlation Between C-Reactive Protein And Stenosis Degree Of Oronary Artery

OBJECTIVE To study correlation between C-Reactive Protein (CRP) and stenosis degree of coronary artery, provide assessment norm for forecast stenosis degree of coronary artery, offering basis for clinical coronary heart disease Percutaneous Coronary Intervention(PCI). METHED We selected 40 patients underwent coronary angiography. Blood samples for measurement of CRP, Cardiac Troponin I (cTnl), Creatine Kinase(CK), MB isoenzyme of CK(CK-MB) and lipoidemia were taken in the morning just before angiography in all patients. Each subject was sought details of sex, age. Body Mass Index(BMI), history of smoking, hypertension, diabetes mellitus. According to the sequence of coronary angiography , the patients were devided into three groups: group A, the stenosis <50%, 13 cases; group B, the stenosis ^50% and <90% , 12 cases; group C, the stenosis 90%. 15 cases , RESULT Among all all the three groups, the prevalence of traditional risk factors for coronary heart disease, including sex, age, BMI, history of smoking, hypertension, diabetes mellitus, lipoidemia were not significantly different between every two groups (P>0.05), and the prevalence of cardiac injury norm Tnl, CK, CK-MB were not significantly different among groups (P>0.05). But the density of CRP in group C is significantly higher than group B and group A (P<0.05) B group is significantly higher than A group (P<0.05 ) . The density of CRP and thepercentage of coronary artery stenosis have linear correlation; In all patients the density of CRP and Tnl have no linear correlation. RESULT The more serious of coronary stenosis , the higher density of CRP in patients.
