Atrial Fibrillation Burden: Moving Beyond Atrial Fibrillation as a Binary Entity: A Scientific Statement From the American Heart Association.
nd Stroke Council Abstract Our understanding of the risk factors and complications of atrial fibrillation (AF) is based mostly on studies that have evaluated AF in a binary fashion (present or absent) and have not investigated AF burden. This scientific statement discusses the published literature and knowledge gaps related to methods of defining and measuring AF burden, the relationship of AF burden to cardiovascular and neurological outcomes, and the effect of lifestyle and risk factor modification on AF burden. Many studies examine outcomes by AF burden classified by AF type (paroxysmal versus nonparoxysmal); h...

Modulation of the autonomic nervous system through mind and body practices as a treatment for atrial fibrillation.
Authors: Bashir MU, Bhagra A, Kapa S, McLeod CJ Abstract Atrial fibrillation is the most common symptomatic arrhythmia that is associated with stroke. Contemporary management of the disease is focused on anticoagulation to prevent stroke, coupled with catheter ablation to limit symptoms and prevent deleterious cardiac remodeling. Emerging data highlights the importance of lifestyle modification by managing sleep apnea, increasing physical activity, and weight loss. There is significant data that supports a link between the autonomic nervous system, arrhythmia development, and atrial fibrillation therapy. It is like...

Obstructive Sleep Apnea and Cardiovascular Disease: A Scientific Statement From the American Heart Association
Circulation. 2021 Jun 21:CIR0000000000000988. doi: 10.1161/CIR.0000000000000988. Online ahead of print.ABSTRACTObstructive sleep apnea (OSA) is characterized by recurrent complete and partial upper airway obstructive events, resulting in intermittent hypoxemia, autonomic fluctuation, and sleep fragmentation. Approximately 34% and 17% of middle-aged men and women, respectively, meet the diagnostic criteria for OSA. Sleep disturbances are common and underdiagnosed among middle-aged and older adults, and the prevalence varies by race/ethnicity, sex, and obesity status. OSA prevalence is as high as 40% to 80% in patients with ...

Bariatric Surgery and the Risk of New-Onset Atrial Fibrillation in Swedish  Obese Subjects
BackgroundObesity is a risk factor for atrial fibrillation, which in turn is associated with stroke, heart failure, and increased all-cause mortality.ObjectivesThe authors investigated whether weight loss through bariatric surgery may reduce the risk of new-onset atrial fibrillation.MethodsSOS (Swedish Obese Subjects) is a prospective matched cohort study conducted at 25 surgical departments and 480 primary healthcare centers in Sweden. The cohort was recruited between 1987 and 2001. Among 4,021 obese  individuals with sinus rhythm and no history of atrial fibrillation, 2,000 underwent bariatric surgery (surgery group), a...

The Impact of Diet and Lifestyle on Atrial Fibrillation
AbstractPurpose of ReviewAtrial fibrillation (AF) is the most common sustained cardiac arrhythmia in humans, affecting more than 33 million people globally. Its association with complex, resource intensive medical conditions such as stroke, heart failure and dementia have had profound impacts across existing health care structures. The global prevalence of AF has enjoyed significant growth despite significant improvement in our armamentarium for arrhythmia treatment.Recent FindingsEfforts aimed at curtailing the incidence, prevalence, or progression of AF have prompted re-evaluation of traditional frameworks for understand...

Supervised Obesity Reduction Trial for AF ablation patients: results from the SORT-AF trial
ConclusionThe SORT-AF study shows that AF ablation is safe and successful in obese patients using continuous monitoring via ILR. Although the primary endpoint of AF burden after ablation did not differ between the two groups, the effects of weight loss and improvement of exercise activity were beneficial for obese patients with persistent AF demonstrating the relevance of life-style management as an important adjunct to AF ablation in this setting.Trial registration numberNCT02064114.

Obesity paradox and cardiovascular diseases
Curr Cardiol Rev. 2022 May 14. doi: 10.2174/1573403X18666220514150051. Online ahead of print.ABSTRACTThe present review summaries data describing the relationship between obesity and cardiovascular outcomes. Links between obesity and chronic coronary syndromes, acute coronary syndromes, coronary revascularization, ischemic stroke, heart failure, hypertension and atrial fibrillation were evaluated. Data from epidemiological studies, prospective studies with lifestyle modification or medical therapy, and results of the meta-analysis were evaluated. The majority of publications report the presence of an 'obesity paradox'. Acc...
