The AF prevalence has increased by three times in the past 50 years, which is related to some new AF risk factors, including: 1) for obesity, the risk of AF increases by 5% for every 1 kg/m2 increase in body mass index (BMI), and the risk increases by 12% for every 9.4 cm increase in waist circumference. The AF risk for obese individuals is 18% higher than that for non-obese individuals. 2) for aging, the risk of AF will increase from 12% in 2010 to 22% in 2040 after the age of 65. 3) for alcohol consumption, moderate alcohol consumption increases the risk of AF by 8%. 4) for social and psychological factors, work pressure, depression, anger, anxiety, sleep disorders, etc. all increase the risk of AF, and the AF risk for those with psychological trauma is 13% higher. 5) for cancer, the incidence of AF significantly increases after a cancer diagnosis, and the AF risk for breast cancer is 14% higher. The AF incidence for cancer patients is 15%~30%. 6) for venous thromboembolism (VTE), the incidence of AF after a VTE diagnosis and the incidence of VTE after an AF diagnosis are both ≥ 70%. 7) for chronic kidney disease, the risk of AF increases by 32%~57% in patients with decreased glomerular filtration rate (GFR). 8) Other factors such as smoking and excessive physical exercise also significantly increase the risk of AF. The mechanisms by which these factors trigger AF include atrial enlargement, activation of the neuroendocrine system, electrical anatomical remodeling, oxidative stress, potassium channel blockade, release of catecholamines, endothelial dysfunction, inflammation, and atrial fibrosis.展开更多
