Relationship of plasma levels of natriuretic peptide and high sensitivity C-reactive protein in the patients with different phenotypes of coronary heart desease / 国际检验医学杂志

ABSTRACT

Objective To observed the changes of plasma levels of NT‐proBNP and hs‐CRP in patients with different types of coronary heart disease and investigate its clinical value .Methods 156 patients with CHD diagnosed by coronary computed tomo‐graphy angiography(CTA) were enrolled in this study ,including 35 cases of acute myocardial infarction(AMI) ,63 cases of unstable angina(UAP) and 58 cases of stable angina(SAP) .And 61 persons without CHD were selected as the control(CTR) .Plasma levels of NT‐proBNP and hs‐CRP were detected by the methods of immmunofluorescent antibody technic reader and turbidimetry ,respec‐tively .Results Plasma NT‐proBNP levels of AMI ,UAP ,SAP and CTR group were (1 903 .99 ± 2 055 .21) ,(897 .27 ± 947 .34) , (677 .98 ± 718 .12) ,(129 .39 ± 126 .49)ng/L ,respect ively .Plasma hs‐CRP levels were (28 .47 ± 20 .49) ,(12 .68 ± 8 .64) ,(10 .56 ± 7 .17) ,(2 .82 ± 1 .23)mg/L ,respectively .Plasma levels of NT‐proBNP and hs‐CRP in AMI group were obviously higher than those in UAP ,SAP and CTR group(P0 .05) . Plasma BNP levels were positively correlated with plasma hs‐CRP .Conclusion Plasma levels of NT‐proBNP and hs‐CRP are asso‐ciated with different clinical phenotyes of CHD .Those markers may be helpful to the risk stratification and prognosis of CHD .
