Atrial fibrillation (AF) is the most common arrhythmia worldwide, and it has a significant effect on morbidity and mortality. It is a significant risk factor for stroke and peripheral embolization, and it has an effect on cardiac function. Despite widespread interest and extensive research on this topic, our understanding of the etiology and pathogenesis of this disease process is still incomplete. As a result, there are no set primary preventive strategies in place apart from general cardiology risk factor prevention goals. It seems intuitive that a better understanding of the risk factors for AF would better prepare medical professionals to initially prevent or subsequently treat these patients. In this article, we discuss widely established risk factors for AF and explore newer risk factors currently being investigated that may have implications in the primary prevention of AF. For this review, we conducted a search of PubMed and used the following search terms (or a combination of terms): atrial fibrillation, metabolic syndrome, obesity, dyslipidemia, hypertension, type 2 diabetes mellitus, omega-3 fatty acids, vitamin D, exercise toxicity, alcohol abuse, and treatment. We also used additional articles that were identified from the bibliographies of the retrieved articles to examine the published evidence for the risk factors of AF.

    • "Atrial fibrillation (AF) is the most common sustained cardiovascular arrhythmia with a lifetime risk of 26% in those 40 years and older (Menezes et al. 2013). Persons with permanent AF experience reduced exercise tolerance, poor quality of life (QoL), weight gain, and an associated decline in overall health. "

    ABSTRACT: Persons with permanent atrial fibrillation (AF) experience reduced exercise tolerance, weight gain, and an associated decline in overall health. We report on a 74-year-old man with permanent AF who underwent a 10-week high-intensity interval training program. Substantial improvements in heart rate, blood pressure, aerobic and functional capacity, and quality of life were observed. These are desirable as these patients are not candidates for other treatment options and more effective therapies for the treatment of AF are needed.

    ABSTRACT: Interaction of cardiovascular (CV) risk factors with structural and hemodynamic alterations as combined promoters of atrial fibrillation (AF) is not yet well studied. We designed an observational, longitudinal, retrospective study to predict risk of incident AF by combination of CV risk profile, target organ damage and therapy in hypertensive patients. We studied 7062 hypertensive patients without history of AF or prevalent CV disease, with ejection fraction (EF) of ≥50%, and no more than stage III chronic kidney disease. The patients were selected from an open registry, the Campania-Salute Network, collecting information from general practitioners and community hospitals, in the Campania Region, Southern Italy, networked with the Hypertension Center of Federico II University Hospital in Naples. The end-point of the present analysis was the detection of first episode of AF by ECG or hospital admission, at any point throughout follow-up (median 36months [IQR=10-74]). During follow-up, AF developed in 117 patients. Baseline older age, greater left atrial diameter (LAd), left ventricular mass (LVM), and intimal medial thickness (IMT) were independent predictors of AF (all p<0.0001), with no effect of CV risk factors. Beta-blockers and diuretics increased risk of incident AF; use of medications inhibiting renin-angiotensin system (RAS) reduced risk by 50% (all p<0.002). Older age, increased LAd, and markers of target organ damage (increased LVM and IMT), identify the hypertensive phenotype at highest risk for AF. CV risk factors do not exhibit significant, independent association. Patients on anti-RAS therapy are exposed to lower risk of incident AF. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    ABSTRACT: Although the paradigm of the 4P medicine - Predictive, Personalized, Preemptive, and Participatory - has been suggested several years ago, its application to atrial fibrillation is still far away. Given the increasing prevalence and incidence of this pathology it is the time to promote preventive strategies, by identifying the risk factors associated to life style and by incentivizing innovative diagnostic technologies. The promotion of the correct life style and of the use of diagnostic devices based on innovative and reliable technologies, represent a first step towards the full realization of the revolution of 4P medicine in atrial fibrillation.
