abstract = {Clonal hematopoiesis (CH) is common among older people and
is associated with an increased risk of atherosclerosis,
inflammation, and shorter overall survival. Age and
inflammation are major risk factors for ischemic stroke, yet
the association of CH with risk of secondary vascular events
and death is unknown. We investigated CH in peripheral blood
DNA from 581 patients with first-ever ischemic stroke from
the Prospective Cohort With Incident Stroke–Berlin study
using error-corrected targeted sequencing. The primary
composite end point (CEP) consisted of recurrent stroke,
myocardial infarction, and all-cause mortality. A total of
348 somatic mutations with a variant allele frequency
$≥1\%$ were identified in 236 of 581 patients $(41\%).$ CH
was associated with large-artery atherosclerosis stroke (P =
.01) and white matter lesion (P < .001). CH-positive
patients showed increased levels of proinflammatory
cytokines, such as interleukin-6 (IL-6), interferon gamma,
high-sensitivity C-reactive protein, and vascular cell
adhesion molecule 1. CH-positive patients had a higher risk
for the primary CEP (hazard ratio [HR], 1.55; $95\%$
confidence interval [CI], 1.04-2.31; P = .03), which was
more pronounced in patients with larger clones. CH clone
size remained an independent risk factor (HR, 1.30; $95\%$
CI, 1.04-1.62; P = .022) in multivariable Cox regression.
Although our data show that, in particular, larger and TET2-
or PPM1D-mutated clones are associated with increased risk
of recurrent vascular events and death, this risk is
partially mitigated by a common germline variant of the IL-6
receptor (IL-6R p.D358A). The CH mutation profile is
accompanied by a proinflammatory profile, opening new
avenues for preventive precision medicine approaches to
resolve the self-perpetuating cycle of inflammation and
clonal expansion.},
