Neurofilament light chain is a protein that forms the neuron cytoskeleton. Higher levels in blood signal neuronal injury in several conditions including stroke, dementia, multiple sclerosis, and amyotrophic lateral sclerosis. Whether plasma NfL levels are a risk marker for future cardiovascular disease is unknown.
To investigate the association of circulating neurofilament light chain levels with the incidence of cardiovascular disease.
Plasma NfL levels were measured from participants enrolled in the community-based Framingham Heart Study Offspring and OMNI1 cohorts using a high sensitivity single molecule array analysis. Using multivariable Cox regression, natural log-transformed plasma NfL levels at baseline were related to the incidence of cardiovascular disease (coronary heart disease, heart failure, stroke, angina, and claudication), and its individual components, over a mean±SD of 5.5±1.6 years follow-up. All models were adjusted for age, sex, and cohort (Offspring or OMNI1).

Among the 2,048 included participants (mean±SD age 69±8 years, 58% women), there were 175 (8.5%) incident cardiovascular events over the study period (2011-2019). Higher plasma NfL levels (per unit of the natural log of the protein level) were associated with an increased risk of cardiovascular disease (hazard ratio [HR]=1.43, 95% confidence interval [CI]=1.05-1.95), coronary heart disease (n=67; HR=1.56, 95%CI=1.00-2.41), and heart failure (n=91; HR=1.67, 95%CI=1.13-2.47), but not stroke (n=60; HR=1.00, 95%CI=0.56-1.78). Associations were non-significant when models were further adjusted for renal function, body mass index, race, current smoking, diabetes, systolic blood pressure, antihypertensive treatment, and high-density lipoprotein level.

Circulating levels of the NfL protein were associated with future risk of all cardiovascular disease, coronary heart disease, and heart failure in minimally adjusted models. NfL is a biomarker of neuronal injury and may also be a risk marker for the onset of cardiac disease. Ongoing research will determine the adjusted risk factors that specifically attenuate this association.
