<b><i>Background:</i></b> The benefit of anticoagulation therapy in atrial fibrillation (AF) and chronic kidney disease (CKD) remains controversial. We aimed to evaluate the impact of renal function on the quality of anticoagulation control, and the effects of both these factors on outcomes in AF. <b><i>Methods:</i></b> Post hoc analysis of the AMADEUS trial. Trial-related outcomes were adjudicated and we studied the composite of first stroke/major bleeding/all-cause mortality, ischaemic stroke, major bleeding, all-cause mortality, and cardiovascular mortality. <b><i>Results:</i></b> We included 2,282 vitamin K antagonist (VKA)-treated patients {<i>n</i> = 787 (34.5%) females; median age 72 (interquartile ranges [IQR] 64–77) years}. Median follow-up was 365 (IQR 189–460) days. There were 1,922 (84.2%) non-CKD and 360 (15.8%) CKD patients. Renal function was inversely correlated with time-in-therapeutic range (<i>r</i> = −0.047, <i>p</i> = 0.025). There was no statistical difference in terms of crude study outcomes based on renal function. Multivariable regression analysis demonstrated that moderate renal failure with estimated glomerular filtration rate of less than 60 mL/min/1.73 m<sup>2</sup> (<i>p</i> = 0.032) and percentage of time-in-therapeutic range (<i>p</i> = 0.011) were independent predictors for the composite outcome of stroke, major bleeding, and all-cause mortality. <b><i>Conclusion:</i></b> Deteriorated renal function has a small negative impact on the quality of anticoagulation control with VKA which is linked to poor outcomes in AF. However, moderate renal failure itself was an independent risk factor for increased risk of stroke, major bleeding, and all-cause mortality amongst patients with AF.

Abstract Background The use of antiarrhythmic drugs in patients with chronic kidney disease (CKD) is challenging due to issues with renal clearance, drug accumulation and increased proarrhythmic risks. Since CKD is a common comorbidity with atrial fibrillation (AF), it is important to establish the efficacy and safety for antiarrhythmic drug treatment in patients with CKD. Purpose To evaluate the efficacy and safety of dronedarone in patients with AF or atrial flutter (AFL) across different stages of renal impairment. Methods In this post-hoc analysis of ATHENA (NCT00174785), a randomised, double-blind trial of dronedarone 400 mg BID vs placebo in patients with AF or AFL plus additional risk factors for death and a calculated glomerular filtration rate ≥10 mL/min, the primary outcome was time to first cardiovascular (CV) hospitalisation or death. Renal function (estimated glomerular filtration rate [eGFR]) was assessed using CKD Epidemiology Collaboration equation and patients were grouped by eGFR (10–44, 45–59, ≥60 mL/min). Log-rank testing and Cox regression were used to compare time to events between treatment groups. Results In ATHENA, 43.6% of placebo and 42.2% of dronedarone patients had mild-to-moderate CKD (Table). Median time to CV hospitalisation/death was longer in all strata for dronedarone vs placebo, reaching significance in the 45–59 and ≥60 mL/min groups (Figure 1). There was a trend towards more treatment-emergent adverse events (TEAEs), deaths and discontinuations due to TEAEs in patients with eGFR 10–44 mL/min. No clear difference in safety was seen between treatment arms except for discontinuations, which were higher with dronedarone. Conclusions This analysis confirms the efficacy of dronedarone, demonstrated in ATHENA, across different stages of renal impairment. Further assessment of safety will require larger populations of patients with CKD. Figure 1 Funding Acknowledgement Type of funding source: Private company. Main funding source(s): Sanofi

Abstract Background In this study considering the relationship between serum endocan and CHA2DS2-VASc score, we assumed that endocan level could be a new biomarker for stroke risk in patients with paroxysmal atrial fibrillation (PAF). It was examined that endocan could be an alternative to determine the risk of stroke and anticoagulation strategy in patients with PAF. The CHA2DS2-VASc scores were calculated for 192 patients with PAF, and their serum endocan levels were measured. The patients were divided into two groups as those with low to moderate (0-1) and those with high (≥ 2) CHA2DS2-VASc scores, and the endocan levels were compared between these two groups. Results The serum endocan level was significantly higher in the high CHA2DS2-VASc score group (p < 0.001). In the multivariate logistic regression analysis, endocan, C-reactive protein, and low-density lipoprotein were found to be independent determinants of the CHA2DS2-VASc score. The predictive value of endocan was analyzed using the ROC curve analysis, which revealed that endocan predicted a high stroke risk (CHA2DS2-VASc ≥ 2) at 82.5% sensitivity and 71.2% specificity at the cutoff value of 1.342. Conclusion This study indicates that endocan is significantly associated with CHA2DS2-VASc score. We demonstrated that endocan could be a new biomarker for the prediction of a high stroke risk among patients diagnosed with PAF.

The Relationship

The relationship of the lay community to clerical institutions during the Middle Ages and especially in the pre–Reformation Era has long been a subject of methodical investigation. It has, however, proven extremely difficult to gain reliable evidence regarding subjective attitudes towards the clergy. Once the basic literary sources have been culled, further elucidation of the development of attitudes on the part of the majority of the people tends to become vague and hesitant or to rely on post hoc explanations. In this brief study, I have experimented with a statistical approach to the problem by tabulating the records of donations to three church institutions of the Lahngau in order to be able to trace, if at all possible, the evolution of attitudes which they reflect. I have, furthermore, attempted to test the hypothesis that the subjective attitudes of a social class towards a church institution are partially conditioned by the effective power exercised on the institution in question at the local level by the donor group.

Abstract Background In heart failure (HF), levels of NT-proBNP are influenced by the presence of concomitant atrial fibrillation (AF), making it difficult to distinguish between HF versus AF in patients with raised NT-proBNP. It is unknown whether levels of GDF-15 are also influenced by AF in patients with HF. In this study we compared the plasma levels of NT-proBNP versus GDF-15 in patients with HF in AF versus sinus rhythm (SR). Methods In a post hoc analysis of the index cohort of BIOSTAT-CHF (n = 2516), we studied patients with HF categorized into three groups: (1) AF at baseline (n = 733), (2) SR at baseline with a history of AF (n = 183), and (3) SR at baseline and no history of AF (n = 1025). The findings were validated in the validation cohort of BIOSTAT-CHF (n = 1738). Results Plasma NT-proBNP levels of patients who had AF at baseline were higher than those of patients in SR (both with and without a history of AF), even after multivariable adjustment (3417 [25th–75th percentile 1897–6486] versus 1788 [682–3870], adjusted p < 0.001, versus 2231 pg/mL [902–5270], adjusted p < 0.001). In contrast, after adjusting for clinical confounders, the levels of GDF-15 were comparable between the three groups (3179 [2062–5253] versus 2545 [1686–4337], adjusted p = 0.36, versus 2294 [1471–3855] pg/mL, adjusted p = 0.08). Similar patterns of both NT-proBNP and GDF-15 were found in the validation cohort. Conclusion These data show that in patients with HF, NT-proBNP is significantly influenced by underlying AF at time of measurement and not by previous episodes of AF, whereas the levels of GDF-15 are not influenced by the presence of AF. Therefore, GDF-15 might have additive value combined with NT-proBNP in the assessment of patients with HF and concomitant AF. Graphic abstract
