Advances in the understanding of clonal hematopoiesis in cardiovascular disease / 中华老年医学杂志

ABSTRACT

Cardiovascular disease is a leading cause of death among the elderly and the incidence of coronary artery disease progressively increases with advancing age.Traditional risk factors are incompletely predictive of cardiovascular disease development.With the advent of high-throughput next-generation genome sequencing technologies in recent years, some studies have indicated that aging is associated with an increased frequency of somatic mutations of hematological neoplasm-related genes in the hematopoietic system, providing a competitive growth advantage for mutant hematopoietic cells and thus allowing for their clonal expansion, a phenomenon known as clonal hematopoiesis of indeterminate potential(CHIP). CHIP is common in middle-aged and elderly populations and is associated with increased risks of hematological cancer and all-cause death.There is growing evidence that CHIP is involved in the development and progression of multiple cardiovascular disorders through the activation of inflammatory responses.In this review, we will give an overview of current advances in the understanding of clonal hematopoiesis in cardiovascular disease.
