Background: Atrial fibrillation (AF) is a major and increasing burden on health services. This study aimed to evaluate the cost-effectiveness of digoxin versus beta-blockers for heart rate control in patients with permanent AF and symptoms of heart failure.

Methods: RAte control Therapy Evaluation in permanent Atrial Fibrillation (RATE-AF) was a randomised, open-label, blinded, endpoint trial embedded in the UK National Health Service (NHS) to directly compare low-dose digoxin with beta-blockers (ClinicalTrials.

Article Synopsis
  • The RATE-AF trial investigated the impact of two heart medications, digoxin and beta-blockers, on heart rate in older patients with atrial fibrillation and heart failure, using consumer-grade wearable technology.
  • Over 20 weeks, heart rate data from 53 participants showed no significant difference between the two treatment groups, regardless of physical activity levels.
  • The study suggests that wearables could effectively monitor patients' heart health remotely, providing comparable predictive insights to traditional clinical assessments.

Artificial intelligence (AI) is increasingly being utilized in healthcare. This article provides clinicians and researchers with a step-wise foundation for high-value AI that can be applied to a variety of different data modalities. The aim is to improve the transparency and application of AI methods, with the potential to benefit patients in routine cardiovascular care.

Objective: To improve the echocardiographic assessment of heart failure in patients with atrial fibrillation (AF) by comparing conventional averaging of consecutive beats with an index-beat approach, whereby measurements are taken after two cycles with similar R-R interval.

Methods: Transthoracic echocardiography was performed using a standardised and blinded protocol in patients enrolled in the RATE-AF (RAte control Therapy Evaluation in permanent Atrial Fibrillation) randomised trial. We compared reproducibility of the index-beat and conventional consecutive-beat methods to calculate left ventricular ejection fraction (LVEF), global longitudinal strain (GLS) and E/e' (mitral E wave max/average diastolic tissue Doppler velocity), and assessed intraoperator/interoperator variability, time efficiency and validity against natriuretic peptides.

Importance: There is little evidence to support selection of heart rate control therapy in patients with permanent atrial fibrillation, in particular those with coexisting heart failure.

Objective: To compare low-dose digoxin with bisoprolol (a β-blocker).

Design, Setting, And Participants: Randomized, open-label, blinded end-point clinical trial including 160 patients aged 60 years or older with permanent atrial fibrillation (defined as no plan to restore sinus rhythm) and dyspnea classified as New York Heart Association class II or higher.

Aims: To establish the extent and impact of symptoms in patients with atrial fibrillation (AF), the importance of different aspects of quality of life (QoL), and how we should assess wellbeing.

Methods: Focus groups of patients with symptomatic permanent AF in a trial of heart rate control; the RATE-AF trial randomised 160 patients aged ≥60 years with permanent AF and at least NYHA class II dyspnoea to either digoxin or beta-blockers. Patient and public representatives led the focus groups and performed all data acquisition and analysis, using thematic approaches to interpret patient views about QoL and its measurement.

Background And Objective: Atrial fibrillation (AF) is common and causes impaired quality of life, an increased risk of stroke and death as well as frequent hospital admissions. The majority of patients with AF require control of heart rate. In this article , we summarise the limited evidence from clinical trials that guides prescription, and present the rationale and protocol for a new randomised trial.
