eLife assessment
In this small-scale study, Fawaz et al. report a significant prevalence of somatic mutations such as Clonal Hematopoiesis of Indeterminate Potential (CHIP) and mosaic loss of Y chromosome (mLOY), but lack of their association with a history of myocardial infarction (MI). The study utilized sensitive techniques, including targeted high-throughput sequencing and digital PCR. The valuable findings by the authors present a contrast to earlier reports, yet they align somewhat with some studies that have demonstrated little or no link between clonal hematopoiesis and atherothrombotic events. Although the study offers convincing results, its limited sample size and brief follow-up period preclude drawing definitive conclusions.
