Cancer-related arterial thromboembolic events.

Cancer is associated with a hypercoagulable state and is a well-known independent risk factor for venous thromboembolism, whereas the association between cancer and arterial thromboembolism is less well established. Arterial thromboembolism, primarily defined as myocardial infarction or stroke is significantly more frequent in patients with cancer, independently of vascular risk factors and associated with a three-fold increase in the risk of mortality. Patients with brain cancer, lung cancer, colorectal cancer and pancreatic cancer have the highest relative risk of developing arterial thromboembolism. Antithrombotic treatments should be used with caution due to the increased risk of haemorrhage, as specified in current practice guidelines.
