چکیده
INTRODUCTION AND OBJECTIVES Better knowledge of C-reactive protein (CRP) kinetics could lead to improved clinical application of this biomarker. METHODS We studied 110 patients: 42 had ST-elevation acute myocardial infarction (STEMI), 35 had non-ST-elevation acute myocardial infarction (NSTEMI), and 33 had unstable angina. Patients were admitted to our institution within 6 hours of symptom onset. The levels of CRP, troponin-I, and creatine kinase MB fraction (CK-MB) were measured on admission and every 6 hours during the first 48 h. The CRP level was also measured daily until hospital discharge. RESULTS The median (interquartile range) CRP level increased relative to baseline from 6 hours after admission, from 5 (2-9) mg/L to 6 (3-10) mg/L (P=.004). Although, CRP levels on admission were similar in all groups, there was a significant difference in peak CRP level: it was 67 (36-112) mg/L in the STEMI group, 29 (20-87) mg/L in the NSTEMI group, and 18 (12-36) mg/L in the unstable angina group. The maximum CRP level was observed 49 (38-53) hours after the onset of symptoms, but occurred later in patients with STEMI. Although there was only a weak non-significant correlation between CRP and troponin levels (r=0.135) at admission, the maximum CRP level was found to be influenced by the degree of myocardial damage (r=0.496; P< .001). CONCLUSIONS The pattern of CRP release observed was clearly different in different forms of acute coronary syndrome. Although the CRP level measured at admission was similar in all patient groups, it was influenced by the degree of early myocardial tissue necrosis. This variation in CRP kinetics should be taken into consideration when designing future studies.

High and low dose atorvastatin effects on high sensivity C-reactive protein in patient with acute coronary syndrome
Introduction: The effect of statins in reducing the risk of acute cardiovascular events is not only due to their effect on serum cholesterol level but also from their anti-inflammatory effects, particularly those resulting from reducing of C - reactive protein (CRP), is important. Atorvastatin dose and duration of treatment display different effects. This study compared the effects of high and ...

Introduction & Objective: Ischemic injury of endothelium is associated with prostaglandin synthesis and platelet adhesion and aggregation, which may be associated with the release of aldehydes such as malondialdehyde (MDA). C-reactive protein and cardiac troponin I have been proposed as diagnostic markers of acute coronary syndromes. In this study, we compared the usefulness of plasma MDA as a ...

Objective(s): This study was designed to investigate the effect of receptor for advanced glycation end products (RAGE), S100A12 and C-reactive protein (CRP) on the release of circulating endothelial cells (CECs) from human coronary artery endothelial cells (HCAECs). Materials and Methods: HCAECs were cultured in increasing concentration of CRP (0, 12.5, 25, 50μg/ml) or S100A12 protein (0, 4, 1...

Introduction: Coronary artery disease (CAD) is among the most common, serious, chronic and life- threatening illnesses in the world. CAD represents a spectrum of conditions, with acute myocardial infarction at one end of it and silent ischemia at the other. There is growing evidence on importance of prognosis of C- reactive protein (CPR) in unstable angina and this protein is a maker of an adve...
متن کاملC-REACTIVE PROTEIN RESPONSE IN ANGINA PECTORIS
C-reactive protein (CRP) response was studied in 44 patients with acute angina pectoris admitted to the coronary care unit. 71 % of patients with acute myocardial infarction (MI)had positive CRP test while 73% of patients presumed to have unstable angina pectoris had negative CRP test. This test can be helpful in differentiating between acute MI and unstable angina pectoris.
