Sept. 11, 2024 — In the first national estimate in two decades, researchers at the University of California-San Francisco (UCSF) report that 10.5 million Americans have atrial fibrillation.
Atrial fibrillation, a rapid, irregular heart beat that can lead to stroke or sudden death, is three times more common than previously thought, affecting nearly 5 percent of the population, or 10.5 million U.S. adults, according to new estimates from University of California-San Francisco.
