RESULTS: Mean BMI was 21.1 ± 4.2. Thoracic fat such ITF, EAT, and PAT was positively correlated with abdominal fat such as TAT, VAT, and SAT. However, adiposity of thorax and abdomen were not significantly associated with in-hospital mortality. ITF was 157.7 ± 105.4 among nonsurvivors but 136.0 ± 88.0 among survivors (p=0.37). VAT was 102.5 ± 77.8 among nonsurvivors but 78.1 ± 47.1 among survivors (p=0.065). In univariate analysis, mortality was associated with male, the maximum amount of inotropic, Simplified Acute Physiology Score II, Sequential Organ Failure Assessment score, bacteremia, azotemia, increased lactate level, chronic lung disease, and the ratio of VAT/SAT and VAT/TAT. After adjustment for covariables, age (odds ratio (OR): 1.130 95% confidential interval (CI): 1.018-1.255) and increased lactate level (OR: 1.049 95% CI: 1.003-1.097) showed significant association with in-hospital mortality, but not visceral fat.
