摘要
AIM： To assess residual diuresis and diverse variables according to body mass index （BMI）.METHODS： Cross-sectional study （n = 57）, with 3 groups. Group A： BMI 〈 25, n = 22; Group B： BMI 25-30, n = 15; Group C： BMI 〉 30, n = 20. Diuresis, hematocrit, albumin, C-reactive protein, Malnutrition infammatory score, Pro-BNP, Troponin T, leptin and in-sulin levels are expressed as median and ranges （r）. RESULTS： Albumin （g/dL）： GA vs GC, 3.70 （r2.20-4.90） vs 3.85 （r3.40-4.90）, P = 0.02. Diuresis （mL/d）： GA 690 （r0-1780）; GB 660 （r60-1800）; GC 840 （r40-2840）. Diuresis GA vs GC, P = 0.01. Leptin （ng/mL）： GA vs GC, 3.81 （r0.78-69.60） vs GC, 32.80 （r0.78-124.50）, P 〈 0.001. Insulin （μU/mL）： GA vs GB, 7 （r2-44） vs 11.50 （r4-38）, P = 0.02; GA vs GC, 7 （r2-44） vs 19.5 （r5-155）, P = 0.0001. Troponin T and Pro-BNP levels were not different. Significant correlations： GC, Insulin-UF： ρ= 0.53; P = 0.03; TroponinT-diuresis： ρ = -0.48, P 〈 0.05; Pro-BNP-diuresis： ρ = -0.39, P 〈 0.01; Troponin T-ProBNP： ρ = 0.77, P 〈 0.0001; albumin-Troponin T： ρ = -0.66, P 〈 0.0001; albumin-ProBNP： ρ = -0.44, P 〈 0.05.CONCLUSION： High BMI associated positively with higher diuresis and albuminemia, and negatively with TropT and Pro-BNP. High BMI-associated better survival may be explained by better urinary output, lowering cardiovascular stress.
