Clonal Hematopoiesis and Thrombosis

Clonal hematopoiesis (CH) has been the focus of many research efforts in the last years and has emerged as a risk modifier for cardiovascular disease morbidity and mortality. While substantial evidence has accumulated regarding its impact on arterial system diseases, the connection with venous thrombosis has only recently been explored. Both clinical and preclinical evidence suggest that the magnitude and mechanism underlying the association of CH with cardiovascular events vary depending on the specific mutated gene involved, indicating a causal link between CH and thrombosis development, not only in the arterial system, particularly in the context of atherosclerosis, but also in venous thrombosis. Although this growing body of knowledge has driven translational research and provided insights for improving clinical management, several questions remain unanswered. This review aims to summarize the available evidence on the link between CH and thrombosis, while highlighting the gaps that need to be addressed in future research.
