In a study, published in the&nbsp;Anatolian Journal of Cardiology, researchers examined the prognostic value of interleukin-6 (IL-6) for mortality and stroke in <a href="https://www.cdc.gov/heartdisease/atrial_fibrillation.htm">atrial fibrillation</a> (AFib). The investigators, led by Xiaoyue Jia, conducted a cohort trial and a meta-analysis and found that increased levels of circulating IL-6 was &ldquo;significantly associated with a greater risk of stroke and all-cause mortality in patients with AFib.&rdquo;The cohort portion of the study followed 217 patients with newly diagnosed, non-valvular AFib for a mean duration of 27 months. The prognostic value of IL-6 for <a href="https://www.docwirenews.com/cardiology/active-screening-for-atrial-fibrillation-to-protect-against-strokes-and-other-events/">stroke and mortality</a> was evaluated with the Cox regression model, and IL-6 was also added to the CHA2DS2-VASc scoring tool to calculate the incremental value. The meta-analysis portion of this study included all reported cohort studies as well as the authors&rsquo; own cohort&rsquo;s data.In their cohort, the researchers found that elevated plasma levels of IL-6 was an independent risk factor for predicting both stroke (hazard ratio [HR] = 3.81; 95% confidence interval [CI], 1.11&ndash;13.05; p = 0.033) and all-cause mortality (HR = 3.11; 95% CI, 1.25&ndash;7.72; p = 0.015) in patients with AFib. Adding IL-6 to CHA2DS2-VASc scoring demonstrated only limited improvement of the predictive power for stroke (area under the curve [AUC] from 0.81 to 0.88; p = 0.005). The follow-up meta-analysis confirmed the associations between increased circulating level of IL-6 and increased risk of stroke (HR = 1.97; 95% CI, 1.22&ndash;3.17; p = 0.006) as well as mortality (HR = 2.73; 95% CI, 2.29&ndash;3.25; p &lt;0.001).The authors presented their data to deepen current understanding of the <a href="https://www.docwirenews.com/docwire-pick/cardiology-picks/atrial-fibrillation-predictors-and-outcomes-in-patients-with-acute-coronary-syndromes/">prognostic value</a> of IL-6 for stroke and mortality in patients with AFib, and they concluded that &ldquo;adding IL-6 biomarker to the CHA2DS2-VASc score may help to determine the management of AF treatment.&rdquo;
