Personalized Care Focusing on Lifestyle Adjustments May Reduce AFib Risk for Individuals
Atrial Fibrillation, a Common Irregular Heartbeat, Tied to Multiple Risk Factors
Atrial fibrillation (AF), the most prevalent type of arrhythmia, affects millions worldwide. Beyond traditional cardiovascular risk factors such as physical activity, diabetes, and smoking, a range of modifiable risk factors contribute to the development of AF.
These risk factors extend to chronic conditions like cardiovascular, respiratory, metabolic, and mental health disorders. For instance, hypertension is a significant risk factor for AF patients, increasing the risk by 1.7 to 2.5 times [2].
Obstructive sleep apnea, a condition affecting 21-74% of AF patients, can enhance the formation of blood clots and alter the heart's structural and electrical properties [4]. Sleep apnea management using a continuous positive airway pressure (CPAP) machine may reduce the risk of AF incidence, recurrence, or progression [4].
Cardiovascular conditions, such as coronary artery disease, hypertension, heart failure, and cardiomyopathies, place individuals at an increased risk of AF.15 Hypertension is one of the most well-known risk factors associated with AF [2]. Control of comorbid cardiovascular conditions can help reduce the risk of complications such as stroke in AF patients.
Diabetes is another risk factor for AF that demands attention. While the relationship between diabetes and AF is not consistently clear from various studies, better blood glucose control and weight reduction can potentially lower the risk [4].
Obesity is also a major factor. Excess weight can increase the risk of AF, recurrence, complications during ablation, stroke, and death. Thus, weight loss can help mitigate the risk of AF recurrence and complications [4].
Smoking and excessive alcohol consumption are also associated with an increased AF risk. The relationship between alcohol consumption and AF appears to be dose-dependent, according to data from multiple studies [4].
Lifestyle modifications, such as regular physical activity, smoking cessation, and a heart-healthy diet, can help manage AF. High-intensity interval training and 150 minutes of moderate-to-vigorous training per week can improve the quality of life in AF patients and lower the risk of AF [4].
Medications like blood thinners, beta-blockers, and calcium channel blockers are essential in AF management. Conventional oral anticoagulants like warfarin have been used for anticoagulation, but nonvitamin K antagonist oral anticoagulants (NOACs) have become the first-line treatment for AF [4].
While multiple risk factors and a multidisciplinary approach are crucial for optimal AF management, challenges remain in achieving ideal outcomes due to the need for a complete lifestyle change and addressing comorbidities [4].
