Serum high-sensitivity C-reaction protein and heart fatty acid binding protein level and cardiac accidents in patients with unstable angina pectoris / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the relationship between serum high-sensitivity C-reaction protein (hs-CRP) and heart fatty acid binding protein (h-FABP) on cardiac accidents in patients with unstable angina pectoris (UAP).</p><p><b>METHOD</b>Serum levels of hs-CRP, h-FABP, cardiac troponin-I (cTn-I) and creatine kinase MB isoenzyme (CK-MB) were measured and cardiac accidents within 2 weeks after the test were observed in 74 patients (male 45) with stable AP (SAP) and 56 patients (male 29) with UAP.</p><p><b>RESULTS</b>The incidence of cardiac accidents was significantly higher in UAP group (26.8%) than that in SAP group (10.53%, P < 0.001). Serum hs-CRP [(7.64 +/- 2.18) mg/L vs. (1.78 +/- 0.62) mg/L, P < 0.001], h-FABP [(16.46 +/- 5.28) microg/L vs. (3.15 +/- 2.61) microg/L, P < 0.001] and cTn-I [(1.28 +/- 0.43) microg/L vs. (0.67 +/- 0.09) microg/L, P < 0.001] levels were also significantly higher in UAP group than those in SAP group. The serum hs-CRP and h-FABP levels for patients with cardiac accidents in the SAP group were (6.32 +/- 2.06) microg/L and (8.76 +/- 3.83) microg/L respectively, which were higher than those for the patients having no cardiac accidents in the control (P < 0.01). The serum hs-CRP, h-FABP, cTn-I and CK-MB levels in patients with cardiac accidents were significantly higher than those in patients without cardiac accidents in both SAP and UAP groups.</p><p><b>CONCLUSION</b>Measuring traditional parameters for myocardial damage (cTn-I and CK-MB) in combination with hs-CRP and h-FABP is valuable for predicting the risk of recent cardiac accidents for AP patients.</p>
