LDH correlates with AST and is increased in patients with impaired liver function. (A) LDH and AST levels correlate in all hospitalized patients. (B) LDH levels correlate with AST concentration in non ICU and ICU patients. Displayed are LDH concentrations in patients with normal AST and elevated AST in (C) non ICU and (D) ICU patients. (E) Correlation heat map of biochemical parameters in all hospitalized patients. Tile colours code for magnitude of the correlation with darker shades indicating stronger correlation. The first two decimal digits of r are displayed. Only significant correlations are shown. Data are shown as mean ± SEM, n: (C-D). *p<0.05; **p<0.01; ***p<0.001 according to Spearman correlation or Student's t-test. LDH, lactate dehydrogenase; AST, aspartate aminotransferase; ICU, intensive care unit.
