abstract = {In light of growing evidence highlighting interactions
between cardiac and brain health, we investigated
associations of biomarkers of neurodegenerative diseases
with adverse outcomes (all-cause and cardiovascular
mortality, major cardiovascular events, and stroke) in
persons with chronic coronary syndrome (CCS).We used data
from a cohort of persons with CCS for whom major adverse
events were recorded over a follow-up of 20 years. We
measured biomarkers of neurodegenerative diseases in
baseline blood samples, using the Single-Molecule Array
Technology on a HD-1 Analyzer. These include biomarkers of
neuronal (neurofilament light chain (NfL) (n = 379)) and
glial neurodegeneration (glial fibrillary acidic protein
(GFAP) (n = 379)), and Alzheimer's disease pathology
(phosphorylated tau181 (n = 379), total tau (n = 377), and
amyloid β (Aβ40, Aβ42, Aβ42/Aβ40) (n = 377)). We
applied Cox-proportional hazards models to evaluate
associations of these biomarkers with adverse outcomes,
adjusting for covariates and exploring interactions with
apolipoprotein E (ApoE) ε4 genotype.Participants with
higher NfL levels had increased rates of all-cause and
cardiovascular mortality (Hazard ratio per increase by one
standard deviation (95 $\%$ confidence interval): all-cause
mortality: 1.36 (1.10-1.68); cardiovascular mortality: 1.42
(1.05-1.93)). The Aβ40/Aβ42-ratio was linked to incident
stroke (0.72 (0.52-1.00)). Associations of GFAP with
all-cause mortality and incident stroke were depending on
ApoE ε4 genotype. The other biomarkers were not
significantly associated with the studied outcomes.In
persons with CSS, NfL and the Aβ40/Aβ42-ratio were related
to mortality and incident stroke, respectively, whereas
associations of GFAP with adverse outcomes varied by ApoE
genotype. These biomarkers might play a role in linking
aging, cardiovascular and neurodegenerative diseases.},
