Highlights
- •Different doses of acute exercise induce specific profiles of circulating microRNAs proposed as biomarkers of heart disease.
- •Circulating microRNAs offer incremental diagnostic value to other cardiac biomarkers in the context of acute exercise.
- •In absence of cardiac damage or dysfunction after acute exercise, circulating microRNAs show “pseudo-disease” signatures.
- •Our results suggest a potential role of circulating microRNAs as mediators of cardiac response to acute exercise.
Abstract
Background
Circulating microRNAs (c-miRNAs) are mediators of intercellular communication with
great potential as cardiac biomarkers. The analysis of c-miRNAs in response to physiological
stress, such as exercise, would provide valuable information for clinical practice
and a deeper understanding of the molecular response to physical activity. Here, we
analysed for the first time the acute exercise response of c-miRNAs reported as biomarkers
of cardiac disease in a well-characterized cohort of healthy active adults.
Methods
Blood samples were collected immediately before and after (0 h, 24 h, 72 h) a 10-km
race, a half-marathon (HM) and a marathon (M). Serum RNA from 10-km and M samples
was extracted and a panel of 74 miRNAs analysed using RT-qPCR. c-miRNA response was
compared with a panel of nine cardiac biomarkers. Functional enrichment analysis was
performed. Pre- and post-M echocardiographic analyses were carried out.
Results
Serum levels of all cardiac biomarkers were upregulated in a dose-dependent manner
in response to exercise, even in the absence of symptoms or signs of cardiac injury.
A deregulation in the profiles of 5 and 19 c-miRNAs was observed for 10-km and M,
respectively. Each race induced a specific qualitative and quantitative alteration
of c-miRNAs implicated in cardiac adaptions. Supporting their discriminative potential,
a number of c-miRNAs previously associated with cardiac disease were undetectable
or stable in response to exercise. Conversely, “pseudo-disease” signatures were also
observed.
Conclusions
c-miRNAs may be useful for the management of cardiac conditions in the context of
acute aerobic exercise.
Translational aspects of the work
Circulating microRNAs could offer incremental diagnostic value to established and
emerging cardiac biomarkers, such as hs-cTnT or NT-proBNP, in those patients with
cardiac dysfunction symptoms after an acute bout of endurance exercise. Furthermore,
circulating miRNAs could also show “pseudo-disease” signatures in response to acute
exercise. Clinical practitioners should be aware of the impact caused by exercise
in the interpretation of miRNA data.
