Abstract:
Objective To investigate plasma levels of high-sensitivity C-reactive protein (hs-CRP) in patients with coronary heart disease (CHD) and relationship between hs-CRP levels and cardiac function. Methods The serum hs-CRP concentrations in 894 CHD patients diagnosed by coronary angiography and 141 healthy controls were measured by particle enhanced immunoturbidimetric assay. Results The median of hs-CRP levels was 1.70 (0.13-19.53 ) mg/L and abnormal ratio was 37.6% (336/894), that were significantly higher in CHD group than healthy controls [0. 99(0. 13-19. 53) rag/L, 7. 1% (10/141) ] (Z=-6. 476,X<'2> = 50. 882, P <0.01 ). The median of hs-CRP levels was 5.35 (0. 18-19. 10) mg/L and abnormal ratio was 63.9% (92/144), that were much higher in acute myocardial infarction (AMI) group than in old myocardial infarction (OMI) group [2.27 (0.13-19.19) mg/L, 43.7% (129/295) ] (Z = -3.353 ,X<'2> = 15. 732, P <0. 01 ). The median of hs-CRP levels was 1.45 (0.19-19.53) mg/L in unstable angina pectoris(UAP) group and abnormal ratio was 29.1% (73/251), that were was higher in stable angina pectoris (SAP) group [1.04 (0.13-16.31 ) mg/L, 20. 6% (42/204) ] (Z=-2.981, P = 0.003;X<'2> = 4.30, P=0.038 ) . Furthermore, Kruskal-Wallis test showed the concentrations of hs-CRP and NT-proBNP was increased along with increment of CHD severity (NYHA functional classification) (X<'2> = 120.185,424.945, P <0.001 ). Multivariate analysis showed that hs-CRP levels positively correlated with NYHA functional classification ( r = 0.328, P <0.01 ) as well as NT-proBNP levels (r=0.413, P <0.01 ). Conclusion Serum hs-CRP level increases along with CHD severity, indicating that hs-CRP may play a certain role in the occurrence and development of CHD.
