Overview
The most common cause of atrial fibrillation is atrial dilation associated with hypertension. Approximately 1/3 of patients have familial atrial fibrillation which is due to an underlying genetic disorder. Given the number of patients who undergo coronary artery bypass grafting in the developed world, this is an increasing underlying cause of atrial fibrillation. Other general causes include the advancing age of the population this hemodynamic stress of heart failure and valvular heart disease, myocardial ischemia, a variety of inflammatory disorders, pulmonary diseases, alcohol and drug abuse, and endocrine disorders.
Risk Classification
Once a patient develops atrial fibrillation, their risk of subsequent events can be assessed using the following tow scores:
CHADS2 Score
CHA2DS2-VASc Score
The risk of bleeding associated with anticoagulation can be assessed using the following score:
