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. As rate control has not yet been shown to reduce mortality, there is a clear need to compare the impact of therapy on quality of life, cardiac function and exercise capacity...

BACKGROUND: Increased physical capacity after comprehensive rehabilitation in patients with atrial fibrillation (AF) undergoing ablation has been found in the CopenHeartRFA trial. The purpose of this study was to investigate: (a) sex differences in health status, psychological distress and quality of life, (b) sex differences in rehabilitation outcomes and (c) predictors of effect of rehabilitation. METHODS: We conducted an exploratory analysis of data from the randomized CopenHeartRFA trial, where patients treated with ablation were randomized with 1:1 to comprehensive rehabilitation consisting of a physical exercise program and psycho-educational consultations versus usual care...

The cardiovascular benefits of regular exercise have been well described, including a significant reduction in cardiovascular morbidity and mortality for those meeting recommended guidelines. Yet the impact of physical activity on the incidence of atrial fibrillation (AF) has been less clear. This review seeks to define the optimal dose and duration for the prevention and treatment of AF. In doing so, we review the evidence that supports a decline in AF risk for those who achieve a weekly physical activity dose slightly above the current recommended guidelines...

Patients with valvular heart disease (VHD) should be treated for diabetes, hypertension, and hyperlipidemia. They also should receive therapy for left ventricular dysfunction, undergo interval echocardiography, and participate in aerobic exercise. Valve replacement should be considered for patients with aortic stenosis (AS) and syncope, presyncope, heart failure, angina, or severe AS with left ventricular dysfunction. Valve replacement is performed with open or transcatheter procedures; the latter are preferred for patients with high surgical risk...

Exercise has substantial health benefits with pleomorphic vascular, metabolic, psychological and anti-neoplastic actions resulting in improved quality of life and longevity. Despite these many benefits, numerous studies have shown that endurance athletes are more likely to develop atrial fibrillation (AF) than non-athletes. The type, intensity and amount of sport appears to influence the risk of developing AF. Several endurance sport activities have been shown to increase the risk of developing AF but an excess in AF has not been shown in non-endurance sports...

Patients with moderate to severe aortic stenosis (AVA <1.3 cm(2)) who were judged, by a referring cardiologist, as asymptomatic or equivocal symptomatic from the aortic stenosis were included in the study. Patients with left ventricular ejection fraction <50% were not included. Twenty-nine percent of the referred patients were judged asymptomatic and 71% equivocal symptomatic from their valve disease. The mean age was 72 years and 90% of the patients had an AVA-index <0.6 cm(2)/m(2). By clinical evaluation in the outpatient clinic, 48% were judged as having functional limitation corresponding to NYHA≥II...

Overweight and obesity are well-established risk factors for most cardiovascular diseases (CVD), including coronary heart disease (CHD), heart failure (HF), and atrial fibrillation. Despite the strong link between excess adiposity and risk of CVD, growing evidence has demonstrated an obesity paradox in patients with CVD. This phenomenon is characterized by a better prognosis in overweight and mildly obese CVD patients than their leaner counterparts. Moreover, the worst outcomes are often incurred by underweight CVD patients, followed by those of normal weight or severely obese...

OBJECTIVES: To examine the association between chronotropic incompetence and incident atrial fibrillation (AF). BACKGROUND: Patients with inadequate heart rate response during exercise may have abnormalities in sinus node function or autonomic tone that predispose to the development of AF. METHODS: We examined the association between heart rate response and incident AF in 57,402 (mean age=54±13 years, 47% female, 64% white) patients free of baseline AF who underwent exercise-treadmill stress testing from the Henry Ford ExercIse Testing (FIT) Project...

Aims: Physical activity is protective against cardiovascular (CV) events, both in general population and in high-risk CV cohorts. However, the relationship between physical activity with major adverse outcomes in atrial fibrillation (AF) is not well-established. Our aim was to analyse this relationship in a 'real-world' AF population. Second, we investigated the influence of physical activity on arrhythmia progression. Methods and Results: We studied all patients enrolled in the EURObservational Research Programme on AF (EORP-AF) Pilot Survey...

OBJECTIVES: This study sought to investigate how right ventricular (RV) contractile function and its coupling with pulmonary circulation (PC) stratify clinical phenotypes and outcome in heart failure preserved ejection fraction (HFpEF) patients. BACKGROUND: Pulmonary hypertension and RV dysfunction are key hemodynamic abnormalities in HFpEF. METHODS: Three hundred eighty seven HFpEF patients (mean age 64 ± 12 years, 59% females, left ventricular ejection fraction 59 ± 7%) underwent RV and pulmonary hemodynamic evaluation by echocardiography (entire population) and right heart catheterization (219 patients)...

BACKGROUND: Patients with atrial fibrillation (AF) have an increased risk of diastolic dysfunction and heart failure. The purpose of this study was to identify independent predictors of early (ie, only exercise-induced) heart failure with preserved ejection fraction (HFpEF) and to describe the prevalence of early HFpEF among patients with paroxysmal AF. METHODS AND RESULTS: One hundred patients with paroxysmal AF and preserved left ventricular ejection fraction (LVEF) underwent catheterization for left atrial pressure (LAP) measurements at rest and at the peak of arm exercise (LAP-exe)...

Estimated cardiorespiratory fitness (e-CRF) based on readily available clinical and self-reported data is a promising alternative to the costly traditional assessment of CRF using exercise equipment, but its role as a predictor for incident atrial fibrillation (AF) is unclear. This study included 10,126 participants (54.5% women, 35% African-American, mean age 63.2 years) from the Reasons for Geographic and Racial Differences in Stroke study who were free of AF at baseline. Baseline (2003 to 2007) e-CRF was determined using a previously validated nonexercise algorithm...

BACKGROUND: Atrial fibrillation (AF) is the most common pathological arrhythmia in horses. After successful treatment, recurrence is common. Heart rate monitors are easily applicable in horses and some devices offer basic heart rate variability (HRV) calculations. If HRV can be used to distinguish between AF and sinus rhythm (SR), this could become a monitoring tool for horses at risk for recurrence of AF. OBJECTIVES: The purpose of this study was to assess whether in horses AF (before cardioversion) and SR (after cardioversion) can be differentiated based upon HRV parameters...

OBJECTIVE: To describe the treatment of persistent supraventricular tachycardia (SVT) in a young horse in endurance training. CASE SUMMARY: A 6-year-old Arab gelding in endurance training presented for a dysrhythmia and decreased performance. SVT was diagnosed and conversion to a normal sinus rhythm was achieved following administration of a constant rate infusion of amiodarone. However, reversion to SVT occurred shortly after initiation of ridden exercise. A second attempt to convert the dysrhythmia with amiodarone failed, but normal sinus rhythm was achieved with transvenous electrical cardioversion (TVEC)...

BACKGROUND: Physical activity at moderate-high intensity is recommended to prevent lifestyle diseases. Patients with atrial fibrillation are at risk of a sedentary lifestyle due to fear of exercise-induced episodes of atrial fibrillation. The burden of arrhythmia can be reduced by physical exercise. The effect of exercise intensity on burden of atrial fibrillation needs to be studied further. METHODS AND RESULTS: In a 12-week randomized controlled trial, 76 patients with paroxysmal/persistent atrial fibrillation were allocated to perform exercise at either low intensity or high intensity (50% and 80% of maximal perceived exertion, respectively)...

BACKGROUND: Soluble suppression of tumorigenicity 2 (sST2) receptor is a biomarker that is elevated in certain systemic inflammatory diseases. Comorbidity-driven microvascular inflammation is postulated to play a key role in heart failure with preserved ejection fraction (HFpEF) pathophysiology, but data on how sST2 relates to clinical characteristics or inflammatory conditions or biomarkers in HFpEF are limited. We sought to determine circulating levels and clinical correlates of sST2 in HFpEF...

BACKGROUND: Exercise-based cardiac rehabilitation may benefit adults with atrial fibrillation or those who had been treated for atrial fibrillation. Atrial fibrillation is caused by multiple micro re-entry circuits within the atrial tissue, which result in chaotic rapid activity in the atria. OBJECTIVES: To assess the benefits and harms of exercise-based rehabilitation programmes, alone or with another intervention, compared with no-exercise training controls in adults who currently have AF, or have been treated for AF...
