The development of congestive cardiac failure in a patient with hairy cell leukemia treated with 2-chlorodeoxyadenosine.

Deoxyadenosines are closely related to adenosine and as such, may interfere with the cardiac adenylate cyclase pathway resulting in cardiac dysfunction. We report a rare case of a 42 year old man who developed transient cardiac failure following treatment with 2-CDA for hairy cell leukemia.
