BACKGROUND AND OBJECTIVES: Serum high sensitivity C-reactive protein (hs-CRP) is a marker of inflammation and may lead to the development of atherosclerosis, adversely affecting mortality. The aim of this study was to evaluate the relationship between baseline hs-CRP level and 12-month clinical outcomes in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) according to their body mass index (BMI) status. SUBJECTS AND METHODS: Using data from the Korea Acute Myocardial Infarction Registry from November 2005 to September 2008, a total of 8174 consecutive AMI patients were studied. Cox proportional hazard model revealed that higher baseline levels of hs-CRP was associated with 12-month all-cause mortality (p=0.045). To further understand this association, patients were divided into 3 groups based on their body mass index: 1) overweight/obese, 2) normal weight, and 3) underweight patients. Then each group was stratified into quartiles based on their hs-CRP. RESULTS: In overweight/obese patients, Cox model showed significant association of hs-CRP with 12-month mortality when adjusted for age and gender (p<0.001), however, after adjustment with multiple covariates, mortality was highest in the 4th quartile {HR 2.382, (1.079-5.259), p=0.032} though statistically insignificant (p=0.172). We observed no significant association of serum hs-CRP with 12-month mortality in normal weight (p=0.681) and underweight (p=0.760) patients. CONCLUSION: Higher baseline hs-CRP level (> or =4.08 mg/dL) in overweight/obese AMI patients showed significant association with 12-month all-cause mortality independent of other prognostic markers.

BACKGROUND AND OBJECTIVES: Non-high density lipoprotein-cholesterol (non-HDL-C) and apolipoprotein B (ApoB) are markers of atherosclerotic risk and predictors of cardiovascular events. The aim of this study was to evaluate clinical impact of non-HDL-C and ApoB on clinical outcomes in metabolic syndrome (MS) patients with acute myocardial infarction (AMI) undergoing percuatneous coronary intervetion. SUBJECTS AND METHODS: We analyzed 470 MS patients (64.4+/-12.0 years, 53.6% male) with AMI who were followed-up for 12-month after percutaneous coronary intervention (PCI) from December 2005 to January 2008 in a single center. These patients were divided into 2 groups based on median values of non-HDL-C and ApoB. We studied their baseline and follow-up relation with 12-month clinical outcomes, all-cause death and major adverse cardiac events (MACE). RESULTS: Mean values of baseline non-HDL-C and ApoB were 141.2+/-43.1 mg/dL and 99.3+/-29.0 mg/dL respectively. During 12-month follow-up 32 MACE (6.8%) and 12 deaths (2.5%) occurred. We observed significant correlation between non-HDL-C and ApoB. Twelve-month MACE and all-cause death after PCI showed no significant relation as non-HDL-C or ApoB levels increased. Follow-up patients (n=306, rate 65%) also did not show significant relation with clinical outcomes. Twelve-month MACE decreased as non-HDL-C and ApoB reduction rates increased. CONCLUSION: There was no significant association between higher non-HDL-C or ApoB and 12-month clinical outcomes in MS patients with AMI undergoing PCI. ApoB was found to be a better predictor of 12-month MACE than non-HDL-C based on their reduction rates.
