Whether there is a link between venous and arterial thrombotic disorders is still a matter of debate. They share common risk factors, such as old age, male sex and obesity. Endothelial dysfunction and inflammation are likely to play a role in determining the simultaneous involvement of the two vascular compartments. Unlike subclinical atherosclerosis, symptomatic complications of atherosclerosis such as myocardial infarction, ischemic stroke and atrial fibrillation are likely to predict the subsequent development of venous thromboembolic (VTE) complications. Patients with VTE, especially those with apparently unprovoked episodes, have a definitely increased risk of subsequent arterial thrombotic disorders. Drugs that reduce the risk of arterial thrombosis are likely to reduce the risk of venous thrombosis and vice versa. In particular, the direct oral anticoagulants have recently been shown to reduce the risk of both vascular disorders. In conclusion, recent evidence provides compelling evidence in support of the link between venous and arterial thrombosis. Future studies are needed to clarify the nature of this association, to assess its extent, and to evaluate its implications for clinical practice.
