Association of atrial fibrillation burden and clinical profile with blood biomarkers: Results from the ISOLATION Ablation Cohort

Figures

• 

  Figure 1. Standardized biomarker values and their associations with baseline characteristics with rhythm at blood draw. Linear regression coefficients and significance levels of associations between standardized biomarkers (columns) and baseline characteristics (rows) in participants with including rhythm at the time of blood draw. Red represents positive correlations and blue represents negative correlations. The color intensity indicates the strength of the associations. Significance levels: ∗P < .05; ∗∗P < .01; ∗∗∗P < .001.

• 

  Figure 2. Standardized biomarker values and the linear regression partial R2 scores with rhythm at blood draw. Linear regression partial R2 scores for standardized biomarkers (columns) in participants with rhythm at the time of blood draw included. Each bar represents the contribution of different baseline characteristics (color-coded) to the variance explained in each biomarker's value, demonstrating their relative influence on each biomarker’s R2 score.

• 

  Figure 3. Standardized biomarker values and their associations with baseline characteristics with preprocedural AF burden. Linear regression coefficients and significance levels of associations between standardized biomarkers (columns) and baseline characteristics (rows) in participants with AF burden. Red represents positive correlations and blue represents negative correlations. The color intensity indicates the strength of the associations. Significance levels: ∗P < .05; ∗∗P < .01; ∗∗∗P < .001.

• 

  Figure 4. Standardized biomarker values and the linear regression partial R2 scores with pre-procedural AF burden. Linear regression partial R2 scores for standardized biomarkers (columns) in participants with AF burden. Each bar represents the contribution of different baseline characteristics (color-coded) to the variance explained in each biomarker’s value, demonstrating their relative influence on each biomarker’s R2 score.
