In recent years there has been an explosion of interest in atrial fibrillation (AF), the most common heart rhythm disorder. Although it is sometimes thought to be relatively benign, AF increases the risk of stroke if untreated. Even if treated, it can be the source of significant discomfort and can contribute to additional complications, especially when accompanied by other cardiovascular conditions. Now a new study published in Circulation finds that hospitalizations for AF are on the increase, and this may have important implications for the delivery and economics of health care in the coming years.
Over the course of a decade the AF hospitalization rate increased by 14.4% (p<0.001), from 1552 to 1812 per million people per year.
