High-sensitivity C-reactive protein and left ventricular remodeling in patients with acute myocardial infarction



High-sensitivity C-reactive protein and left ventricular remodeling in patients with acute myocardial infarction



Heart and Vessels 18(2): 67-74



Inflammatory cytokines are suspected to play an important role in the pathophysiology of left ventricular (LV) remodeling. We investigated whether high-sensitivity C-reactive protein (CRP) (hs-CRP) is a predictor for LV remodeling in patients with acute myocardial infarction (AMI) with successful reperfusion, and also whether such a situation can be avoided by the administration of angiotensin-converting enzyme inhibitors (ACEI) or angiotensin II receptor blockers (ARB). The subjects were 139 patients with an initial attack of anterior myocardial infarction successfully treated by reperfusion therapy. They were randomly divided into the following two groups: an angiotensin (AG) group (91 patients treated with ACEI/ARB) and a NON-AG group (48 patients not treated with ACEI/ARB). Levels of hs-CRP, creatine kinase, human atrial natriuretic polypeptide, brain natriuretic peptide (BNP), fasting blood glucose, serum lipids, fibrinogen, fibrin degradation product, prothromloin time, and activated partial thromboplastin time were measured immediately after 1, 2, 3, and 7 days, and 1 months after the onset of AMI. ACEI or ARB administration lowered hs-CRP levels and prevented the development of LV remodeling. Peak CRP levels significantly correlated with BNP levels during the acute stage (r = +0.54, P < 0.0001), end-diastolic volume index (r = +0.78, P < 0.0001), end-systolic volume index (r = +0.36, P = 0.0405), ejection fraction (r = -0.45, P = 0.0052), left ventricular end-diastolic diameter (r = +0.61, P < 0.0001), cardiac output (r = -0.52, P = 0.0005), cardiac index (r = -0.41, P = 0.0099), and systolic pulmonary arterial pressure (r = +0.48, P = 0.0017) 1 month after the onset of AMI in the NON-AG group but not in the AG group. Logistic multivariate analysis revealed that peak CRP alone was an independent risk factor for the development of LV remodeling in the NON-AG group (odds ratio = 1.79, P = 0.002). These results suggest that hs-CRP is a useful factor for predicting LV remodeling. Furthermore, ACEI or ARB administration to AMI patients showing increased hs-CRP levels during the early stage of the disease could prevent LV remodeling.
