Personalized Approach to Lifestyle Factors May Decrease Risk of Atrial Fibrillation
Atrial fibrillation, commonly known as AFib, is the most common arrhythmia, with a global prevalence exceeding one in forty people [1]. It's characterized by an irregular heart rhythm due to the upper chamber of the heart beating abnormally. This phenomenon can lead to the formation of blood clots in the atrium, which might travel to the brain, causing a stroke—making AFib a significant risk factor for stroke [1].
Aside from recognized risk factors linked to cardiovascular health, such as physical activity, diabetes, obesity, and smoking, chronic conditions like cardiovascular, respiratory, metabolic, and mental health issues are also associated with an increased risk of AFib [1]. Research, as published in European Heart Journal, emphasizes the significance of lifestyle factors, comorbid conditions, and socioeconomic factors in AFib [2].
To effectively manage AFib and reduce the risk of death and other health conditions, Dr. Stephen Tang, MD, a board-certified cardiac electrophysiologist, highlights the importance of addressing numerous risk factors and comorbidities. He explains that traditional treatments like oral anticoagulation for stroke prevention or rate or rhythm control with medication or ablation might not suffice due to the complex interplay of factors driving AFib [2]. Instead, comprehensive management is crucial.
Risk factors and treatments for AFib
AFib is a heart condition resulting from an irregular beating of the left upper chamber or atrium, often leading to the development of blood clots that can travel to the brain and cause a stroke. While genetic factors, age, sex, and various underlying health conditions cannot be altered (nonmodifiable risk factors), there are several modifiable risk factors that can be managed to reduce the risk of AFib development [1].
Medications and Lifestyle Changes
Medications such as blood thinners, also called anticoagulants, can help minimize the risk of blood clot formation and stroke. Traditionally, warfarin, a drug targeting vitamin K, has been conventionally used as an oral anticoagulant, but newer nonvitamin K antagonist oral anticoagulants (NOACs) that block other factors are increasingly becoming the first line of treatment for AFib [3]. Other drugs like beta-blockers and calcium channel blockers are valuable in controlling the heart rate in individuals with AFib [3].
When lifestyle modifications and medications prove insufficient in managing AFib, invasive procedures like catheter ablation may be necessary to restore a normal heart rhythm [3].
Lifestyle Factors
Physical activity, diet, and sleep habits play essential roles in AFib risk management. Regular physical activity reduces the risk of AFib incidence, recurrence, morbidity, and mortality. Meeting the recommended level of at least 150 minutes of moderate-to-vigorous training per week lowers the risk of AFib [4]. High-intensity interval training is particularly effective in reducing morbidity and improving quality of life in individuals with AFib [4].
Although evidence supporting the role of physical activity in stroke prevention is lacking, weight loss can help reduce the risk of AFib recurrence and associated complications [4]. By contrast, smoking and heavy alcohol consumption are risk factors for AFib [3]. While the relationship between moderate-to-heavy alcohol consumption and AFib risk is clear, data on low levels of alcohol intake are less consistent [3].
Comorbid Conditions
Obstructive sleep apnea, cardiovascular diseases, diabetes, metabolic conditions, and chronic kidney disease are common comorbidities associated with AFib. Managing and treating these conditions is crucial in reducing the risk ofAFib recurrence and associated complications like stroke. Anticoagulant therapy or catheter ablation is essential for preventing complications associated with these conditions [1].
Socioeconomic Factors
Postcode prescribing, a concept that implies lower socioeconomic status can limit access to preventive care and healthcare, may increase the risk of developing AFib and associated complications. Individuals with lower socioeconomic status are less likely to receive anticoagulant therapy and are more likely to discontinue treatment [1]. Healthcare utilization and awareness of AFib symptoms may be limited in lower socioeconomic populations, leading to delayed diagnosis and treatment. Environmental stressors may also exacerbate conditions leading to AFib and further aggravate health disparities in lower socioeconomic populations.
Individualized Care
Given the multifactorial nature of AFib, a multidisciplinary, individualized care approach is necessary. Tailoring management strategies to a person's specific needs, risk factors, and access to healthcare is crucial in reducing the risk of AFib recurrence, complications, and mortality [5]. Prioritizing the treatment of modifiable risk factors, addressing comorbid conditions, and understanding the impact of socioeconomic factors on AFib progression can help reduce its incidence and improve outcomes.
