CHF = congestive heart failure; CI = confidence interval; TD = thiamin deficiency; TPP = thiamin pyrophosphate.

  • Includes all CHF patients, n = 100.

  • Excludes CHF patients taking thiamin-containing supplements before or during hospital admission, n = 78. Thiamin deficiency defined as erythrocyte TPP concentration <78 ng/ml packed erythrocytes.

  • Significant at p value <0.05.
