Atrial fibrillation (AF) risk factors encompass a range of medical conditions and lifestyle factors that contribute to the development or exacerbation of this common heart rhythm disorder. Age is a significant risk factor, with AF prevalence increasing with advancing age. Other cardiovascular conditions such as hypertension, coronary artery disease, and heart failure significantly elevate the risk of AF. Diabetes, obesity, and sleep apnea also predispose individuals to atrial fibrillation. Lifestyle choices such as excessive alcohol consumption, smoking, and sedentary behavior further heighten the risk. Additionally, certain underlying medical conditions like thyroid disorders and chronic kidney disease can increase susceptibility to AF. Understanding and managing these risk factors are crucial for preventing or managing atrial fibrillation and reducing the associated complications.
