Plasma Concentration and Pharmacodynamics of Edoxaban in Patients with Nonvalvular Atrial Fibrillation and Acute Heart Failure.

ABSTRACT:

Objective

The objective of this study was to assess the pharmacokinetic and pharmacodynamic profiles and safety of edoxaban in patients with nonvalvular atrial fibrillation (NVAF) who were hospitalized with acute heart failure (AHF).

Methods

The trough plasma concentrations of edoxaban, and the coagulation biomarkers prothrombin fragments 1 and 2 (F1+2) and D-dimer, were determined. Twenty-six patients received edoxaban 60 mg (30 mg when dose adjustment was required) and blood samples were collected immediately before oral edoxaban administration for 7 consecutive days after hospitalization and on the day of discharge.

Results

The mean observation period was 13 (range 7-46) days. Trough plasma concentrations of edoxaban were constant from day 2 onwards. On day 1, the variation was greater owing to the differing intervals between the last edoxaban dose and day 1 blood collection. Trough plasma concentrations were higher in patients with reduced creatinine clearance (≤ 50 mL/min). Median values for F1+2 and D-dimer remained within normal ranges throughout the study. There were no drug discontinuations, and no serious adverse events were reported.

Conclusions

This is the first study of edoxaban pharmacokinetics and pharmacodynamics in patients with NVAF and AHF, and shows that the pharmacokinetic and pharmacodynamic profiles of edoxaban were constant during hospitalization. Thus, even in patients with NVAF and AHF, edoxaban anticoagulation therapy with guided dose adjustment is considered to be a safe and appropriate intervention. In particular, patients with reduced creatinine clearance should adhere to dose adjustment criteria.

Project description:AimsTachycardia is a reversible event that may cause hemodynamic decompensation but may not necessarily cause direct damages to the myocardium. To evaluate the clinical outcomes of patients with heart failure (HF) and atrial fibrillation (AF), whose acute decompensation was tachycardia mediated.Methods and resultsThe Korean Acute Heart Failure registry was a prospective registry that consecutively enrolled 5625 patients with acute HF. Patients were classified into three groups according to the rhythm and aggravating factor: (i) 3664 (65.1%) patients with sinus rhythm (SR), (ii) 1033 (18.4%) patients with AF whose decompensation was tachycardia-mediated, AF-TM (+), and (iii) N = 928 (16.5%) patients with AF whose decompensation was not tachycardia-mediated, AF-TM (-). The primary outcomes were in-hospital and post-discharge 1 year all-cause mortality. At admission, the mean heart rate was 90.8 ± 23.4, 86.8 ± 26.8, and 106.3 ± 29.7 beats per minute for the SR, AF-TM (-), and AF-TM (+) groups, respectively. The AF-TM (+) group had more favourable characteristics such as de novo onset HF, less diabetes, ischaemic heart disease, and higher blood pressure than the AF-TM (-) group. In-hospital mortality rates were 5.1%, 6.5%, and 1.7% for SR, AF-TM (-), and AF-TM (+) groups, respectively. In logistic regression analysis, the AF-TM (+) group had lower in-hospital mortality after adjusting the significant covariates (odds ratio, 0.49; 95% confidence interval, 0.26-0.93). The mortality rate did not differ between SR and AF-TM (-) groups. During 1 year follow-up, 990 (18.5%) patients died. In univariate and multivariate Cox proportional regression analyses, there was no difference in 1-year all-cause mortality between the three groups.ConclusionsIn patients with HF and AF, patients whose acute decompensation is tachycardia-mediated have better in-hospital, but similar post-discharge outcomes compared with those with SR or those with AF whose decompensation is not tachycardia-mediated.Clinical trial registrationClinicalTrial.gov NCT01389843.

Project description:ObjectivesThis study sought to characterize the course of decongestion among patients hospitalized for acute heart failure (AHF) by history of atrial fibrillation (AF) and/or atrial flutter (AFL).BackgroundAF/AFL and chronic heart failure (HF) commonly coexist. Little is known regarding the impact of AF/AFL on relief of congestion among patients who develop AHF.MethodsWe pooled patients from 3 randomized trials of AHF conducted within the Heart Failure Network, the DOSE (Diuretic Optimization Strategies) trial, the ROSE (Renal Optimization Strategies) trial, and the CARRESS-HF (Cardiorenal Rescue Study in Acute Decompensated Heart Failure) trial. The association between history of AF/AFL and in-hospital changes in various metrics of congestion was assessed using covariate-adjusted linear and ordinal logistic regression models.ResultsOf 750 unique patients, 418 (56%) had a history of AF/AFL. Left ventricular ejection fraction was higher (35% vs. 27%, respectively; p < 0.001), and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels were nonsignificantly lower at baseline (4,210 pg/ml vs. 5,037 pg/ml, respectively; p = 0.27) in patients with AF/AFL. After adjustment of covariates, history of AF/AFL was associated with less substantial loss of weight (-5.7% vs. -6.5%, respectively; p = 0.02) and decrease in NT-proBNP levels (-18.7% vs. -31.3%, respectively; p = 0.003) by 72 or 96 h. History of AF/AFL was also associated with a blunted increase in global sense of well being at 72 or 96 h (p = 0.04). There was no association between history of AF/AFL and change in orthodema congestion score (p = 0.67) or 60-day composite clinical endpoint (all-cause mortality or any rehospitalization; hazard ratio: 1.21; 95% confidence interval: 0.92 to 1.59; p = 0.17).ConclusionsMore than half of the patients admitted with AHF had a history of AF/AFL. History of AF/AFL was independently associated with a blunted course of in-hospital decongestion. Further research is required to understand the utility of specific therapies targeting AF/AFL during hospitalization for AHF.
