- •Fasting ketonuria was associated with lower progression of coronary calcification.
Abstract
Background and aims
Increased levels of ketone bodies, an alternative fuel when glucose availability is
low, may exert beneficial effects on cardiovascular disease (CVD) risk factors. Whether
increased ketone bodies are associated with coronary artery calcium (CAC), a recognized
and strong cardiovascular risk factor, remains unknown. We investigated the association
of fasting ketonuria with CAC and its progression.
Methods
Cross-sectional and longitudinal studies were conducted in adults without diabetes
or CVD. Subjects underwent routine health examinations including cardiac computed
tomography estimations of CAC scores. Logistic regression models were performed to
compute the odds ratios (ORs), 95% confidence intervals (CIs), for prevalent CAC scores
>0 according to fasting ketonuria categories (0, 1, and ≥2). Linear mixed models with
random intercepts and random slopes were used to estimate CAC progression.
Results
Of 144,346 subjects, 12.3% had CAC scores >0 at baseline. Overall, higher fasting
ketonuria was associated with decreased prevalence of coronary calcification than
no ketonuria. Multivariable-adjusted ORs (95% CIs) for prevalent CAC by comparing
ketonuria categories 1 and ≥2 with no ketonuria, were 0.94 (0.84–1.06) and 0.82 (0.71–0.95),
respectively. The associations did not differ according to clinically relevant subgroups.
Ketonuria was associated with lower CAC progression over time; the multivariable adjusted
ratio of progression rates comparing ketonuria ≥2 versus no ketonuria was 0.976 (0.965–0.995).
Conclusions
We found an inverse association between fasting ketonuria and subclinical coronary
atherosclerosis, in both prevalence and progression. The potentially protective role
of increased ketone body formation in CVD requires further investigation.
