What is the prevalence of atrial fibrillation in pregnant women?
The prevalence of atrial fibrillation in pregnant women is very rare, unless when there is an underlying structural heart disease or hyperthyroidism. In countries where the prevalence of rheumatic heart disease is still high or among immigrants from these areas to Western countries, the prevalence of AF in pregnancy may be commonly related to rheumatic heart disease. In a registry of > 250,000 pregnancies in Southern AF was evident in 0.6 per 1,000, more frequently in white women (1.1 per 1,000 pregnancies), and was associated with more advanced age, higher BMI, hypertension, hyperlipidemia, and diabetes.
