Recent publications have suggested that imatinib (Glivec) may be cardiotoxic. We have therefore assessed the largest study on the agent performed in patients with gastrointestinal stromal tumours, randomising a daily dose of 400 mg versus 800 mg. 946 Patients were entered, 942 patients received at least one dose of imatinib. The median time on treatment was 24 months. A total of 24,574 exposure months could be analysed. We could not identify an excess of cardiac events in the study population. In 2 patients (0.2%) a possible cardiotoxic effect of imatinib could not fully be excluded. The current analysis of a large randomised prospective study could not confirm previous suggestions of imatinib induced cardiac toxicity.
