Causes of Atrial Fibrillation
There is no specific cause of atrial fibrillation. It might be associated with different conditions. Cardiomyopathy, after heart surgery, heart valve disease, heart failure, coronary artery disease, high blood pressure, pulmonary hypertension, coronary lungs disease, and congenital heart disease are more common causes of this condition.
Pericarditis, viral infection, and hyperthyroidism are less common causes. In at least 10% of patients, there is no evidence of underlying cardiac disease. Atrial fibrillation may be associated with excessive caffeine or alcohol consumption, stress, certain medicines, electrolyte or metabolic abnormalities, severe infections, or genetic reasons in these circumstances.
None of such causes are present in some cases. The risk of atrial fibrillation rises with age, especially after 60.
