主要研究背景及目的
Clonal hematopoiesis of indeterminate potential (CHIP) is used to describe people who have recurrent mutations in genes related to hematologic malignancies but without a diagnosis of any hematologic malignancy or other clonal disorder. Evidence showed that presence of CHIP was increase with age and it was significantly associated with the risk for coronary heart disease. However, few studies focus on the mechanisms of CHIP in stroke recurrence. Thus, our study aims to assess the incidence of CHIP in patients with stroke and investigate the potential mechanisms of CHIP in stroke recurrence.
方法
We studied a prospective cohort of 6016 patients who had a first-ever AIS in China. Whole-genome sequencing was performed to identify CHIP. High-sensitivity C reactive protein (hs-CRP) levels above 3 mg/L at baseline were defined as hyperinflammation. Recurrent stroke during the 3-month follow-up was the primary outcome.
结论
Our results suggest that somatic mutations contributing to CHIP increase the risk of short-term recurrent stroke in patients who had a first-ever AIS. Hyperinflammation may be important in the relationship between CHIP and recurrent stroke.
