To the Editor: In their letter on the use of heparin during cardiopulmonary bypass in patients with a history of heparin-induced thrombocytopenia, Pötzsch et al. (Aug. 17 issue)¹ do not mention whether they obtained informed consent from the subjects in the study. This study posed substantial risk because heparin-induced thrombocytopenia and thrombosis can have devastating consequences. When studies involving substantial risk to subjects are reported in the Correspondence section, it would be reassuring to see it clearly stated that informed consent was obtained.
