Objective To study the clinical value of heart-type fatty acid-binding protein (H-FABP) in early diagnosis of acute myocardial infarction(AMI). Methods Totally 156 patients who were suspicious to be AMI were divided into group A (0～3 h group) and group B (3～6 h group) ac-cording to the visit time.

Adiponectin and all-cause mortality in elderly people with type 2 diabetes

OBJECTIVE To assess the association between serum adiponectin level and all-cause mortality in people with type 2 diabetes. Because of the insulin-sensitizing, anti-inflammatory, and antiatherogenic effects of adiponectin, we hypothesized that higher adiponectin level would be associated with lower all-cause mortality. RESEARCH DESIGN AND METHODS A total of 609 men and women aged 72 ± 6.3 years with type 2 diabetes and information on total and high molecular weight adiponectin were followed for a median of 5 years. The longitudinal association between adiponectin and all-cause mortality was analyzed with Cox proportional hazards models with time from adiponectin measurement to death as the time-to-event variable. Analyses were adjusted for demographic variables and significant diabetes parameters, significant cardiovascular parameters, and significant diabetes medications. RESULTS Total and high molecular weight adiponectin were highly correlated. The highest adiponectin quartile was strongly associated with higher all-cause mortality compared with the lowest quartile (hazard ratio = 4.0 [95% CI: 1.7-9.2]) in the fully adjusted model. These results did not change in analyses stratified by sex and thiazolidinedione use, after exclusion of people who died within one year of adiponectin measurement, or when change in weight before adiponectin measurement was considered. CONCLUSIONS Contrary to our hypothesis, higher adiponectin level was related to higher all-cause mortality. This association was not explained by confounding by other characteristics, including medications or preceding weight loss.     

慢性心力衰竭患者心型脂肪酸结合蛋白与超敏C-反应蛋白的变化及其相关性

Objective To examine clinical significance and relativity of heart-type fatty acid binding protein (H-FABP) and high-sensitivity C-reactive protein (hs-CRP) in patients with chronic heart failure. Methods Ser-um concentrations of H-FABP and hs-CRP were measured in 60 patients with chronic heart failure and 30 control subjects. Left ventricular ejection fraction (LVEF) was examined by Doppler echocardio graphic in all subjects. Re-sults Serum concentrations of H-FABP and hs-CRP were higher in patients with chronic heart failure than in con-trol subjects[(6.11±1.49)μg/L vs (4.24±1.40)μg/L,and (12.77±3.65)mg/L vs(4.85±1.35) mg/L,t=5.746 and 7.543,P<0.01] but LVEF was lower in patients with chronic heart failure than in control subjects [(42.13±6.55) % vs (61.50±3.89) %,t=-14.902,P<0.01]. In CHF subgroups,H-FABP and hs-CRP lev-el increased with advancing NYHA class (F=26.288 and 351.784,P<0.01) but LVEF decreased (F=252.834,P<0.01). The serum H-FABP concentrations had a positive correlation with serum hs-CRP concentrations (r=0.801,P<0.01),and a negative correlation with LVEF (r=-0.718,P<0.01) ;serum hs-CRP concentrations had a negative correlation with LVEF(r=-0.881,P<0.01). Conclusion Serum H-FABP and hs-CRP levels are in-creased with the worsening of CHF. H-FABP and hs-CRP level are pnsitiviely related. The quantitative determination of serum concentrations of H-FABP and hs-CRP is valuable for risk stratification in patients with chronic heart fail-ure.
