Abstract

Background MicroRNAs (miRNAs) are associated with cardiovascular disease and control gene expression and are detectable in the circulation. Objective The purpose of this study was to test the hypothesis that circulating miRNAs may be associated with atrial fibrillation (AF). Methods Using a prospective study design powered to detect subtle differences in miRNAs, we quantified plasma expression of 86 miRNAs by high-throughput quantitative reverse transcriptase-polymerase chain reaction in 112 participants with AF and 99 without AF. To examine parallels between cardiac and plasma miRNA profiles, we quantified atrial tissue and plasma miRNA expression using quantitative reverse transcriptase-polymerase chain reaction in 31 participants undergoing surgery. We also explored the hypothesis that lower AF burden after ablation would be reflected in the circulating blood pool by examining change in plasma miRNAs after AF ablation (n = 47). Results Mean age of the cohort was 59 years; 58% of participants were men. Plasma miRs-21 and 150 were 2-fold lower in participants with AF than in those without AF after adjustment (P ≤.0006). Plasma levels of miRs-21 and 150 also were lower in participants with paroxysmal AF than in those with persistent AF (P <.05). Expression of miR-21, but not of miR-150, was lower in atrial tissue from patients with AF than in those without AF (P <.05). Plasma levels of miRs-21 and 150 increased 3-fold after AF ablation (P ≤.0006). Conclusion Cardiac miRs-21 and 150 are known to regulate genes implicated in atrial remodeling. Our findings show associations between plasma miRs-21 and 150 and AF, suggesting that circulating miRNAs can provide insights into cardiac gene regulation.

  • Elite athletes may present higher levels of profibrotic markers which have been associated with incident or recurrent AF in the general population, including galectin-3, ST2, miR-21, TIMP-1, CITP, and PICP.

    “Elite athletes may present higher levels of profibrotic markers which have been associated with incident or recurrent AF in the general population [66,67,68], including galectin-3 [69], the suppression of tumorigenicity 2 (ST2) [70], and microRNA-21 (miR-21) [71], as well as tissue inhibitors of metalloproteinase 1 (TIMP-1), C-terminal telopeptide of type I collagen (CITP), and procollagen type I”

    The Results (page unavailable) associate miR-21 with AF and describe its role in atrial fibrosis, supporting its inclusion as an AF-related marker. The study does not examine elite athletes or establish an association with incident or recurrent AF; it reports lower, not higher, plasma miR-21 levels in participants with AF than in controls.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
