The health care costs of treating Americans with atrial fibrillation totaled $26 billion per year, with $6 billion spent for A-fib care, $9.9 billion for other heart risk factors and $10.1 billion for non-heart-related problems, a study in the journal Circulation: Cardiovascular Quality and Outcomes found. Researchers also learned that A-fib patients were more likely to be hospitalized for any causes, had higher deaths during such hospitalizations and spent more on health care compared with those without the condition.
