To the Editor: Enhanced platelet aggregation responses to stimulation with ADP or thrombin receptor agonist peptides (TRAP) have been observed during heparin therapy in patients with unstable angina. However, the platelet aggregation curve in Figure 3 of the article by Xiao and Theroux1 was not obtained from a direct detection to evaluate heparin-induced hyperaggregation.A new platelet aggregometer (AG-10; Kowa, Japan) that uses a laser-light-scattering beam was introduced.2 Platelet aggregates, the size of which was measured as total voltage of …
