Background: Biomarkers of myocardial necrosis may be increased in patientswith chronic heart failure. We investigated whether ischaemia-modifiedalbumin (IMA), a marker of ischaemia, is also elevated in patientswith compensated heart failure, due to dilated cardiomyopathy(DCM).

Methods: We studied 42 patients with DCM and an equal number of age-matchednormal volunteers. We assessed IMA serum levels with the albumincobalt binding test.

Results: IMA was 89.9 ± 13.1 (71–117) KU/L in the patient group and 93.9 ± 9.9 (76–122) KU/L in the control group, with no significant difference between the two (P = 0.11). However, IMA differed significantly according to the New York Heart Association classification (P = 0.003) and was negatively correlated with the left ventricular ejection fraction (r = –0.40, P = 0.014).

Conclusions: We conclude that IMA, a marker of ischaemia, does not differin patients with clinically stable DCM compared with normalsubjects, but varies significantly in relation to the severityof the disease.
