Associations of Dietary and Lifestyle Components with Atrial Fibrillation

Atrial fibrillation (AF) is a prevalent cardiac arrhythmia that still remains a significant health concern, especially due to its consequences, including stroke and heart failure. This review explores the intricate interplay between AF, lifestyle choices, and dietary habits. It is particularly focused on findings from diverse studies about non-pharmacological methods of managing AF. Moreover, its purpose is to elucidate the implementation of lifestyle changes such as physical activity or proper diet choices in the integrated treatment strategy of patients with AF.

Beyond Ablation in Atrial Fibrillation: 10 Steps to Better Control

The prevention and treatment of atrial fibrillation includes risk factor modification beyond ablation, with lifestyle modifications including treatment of obesity through diet and moderate exercise being at the top of the list. Losing 10% of body weight if obese, a plant-based diet, exercise, maintaining systolic blood pressure below 130 mm Hg, treatment of sleep disorders and obstructive sleep apnea, stress management, and treatment of depression and anxiety should all be included in treatment. Maximizing evidence-based treatment of chronic obstructive pulmonary disease and diabetes is also paramount.

Low-Carbohydrate Diets and Risk of Incident Atrial Fibrillation: A Prospective Cohort Study

Background The influences of low-carbohydrate diets in cardiovascular disease are controversial. Few studies have examined the relationship of carbohydrate intake and risk of incident atrial fibrillation ( AF ). We aimed to evaluate the association between carbohydrate intake and the risk of incident AF in the ARIC (Atherosclerosis Risk in Communities) Study. Methods and Results We included 13 385 participants (age, 54.2±5.8 years; 45.1% men and 74.7% white) who completed a dietary questionnaire at baseline (1987-1989) in the ARIC Study. The primary outcome was incident AF , which was identified by ECG performed during study examinations, hospital discharge codes, and death certificates. We used multivariable Cox hazard regression models to assess the association between carbohydrate intake and incident AF . We further explored the effects of specific food source (animal versus plant based) used to replace carbohydrate intake in the low-carbohydrate intake setting. During a median follow-up of 22.4 years, 1808 cases (13.5%) of AF occurred. The hazard ratio for incident AF associated with a 1- SD (9.4%) increase in carbohydrate intake as a percentage of energy intake was 0.82 (95% CI , 0.72-0.94), after adjustment for traditional AF risk factors and other diets factors. Results were similar when individuals were categorized by carbohydrate intake quartiles (hazard ratio, 0.64; 95% CI , 0.49-0.84; comparing extreme quartiles). No association was found between the type of protein or fat used to replace the carbohydrate and risk of incident AF . Conclusions Low-carbohydrate diets were associated with increased risk of incident AF , regardless of the type of protein or fat used to replace the carbohydrate.
