New Study Reveals Over 10 Million U.S. Adults Affected by Serious Heart Condition
Comprehensive National Estimate Reveals 10.5 Million Americans Living with Atrial Fibrillation
According to the first comprehensive national estimate in two decades, researchers at UC San Francisco reveal that 10.5 million Americans are living with atrial fibrillation—a serious yet highly manageable form of heart arrhythmia.
Atrial fibrillation, often referred to as A-Fib, is characterized by a rapid and irregular heartbeat that heightens the risk of stroke or sudden death. Recent data suggests the condition is nearly three times more prevalent than previous estimates, affecting close to 5% of the U.S. adult population—around 10.5 million individuals.
Factors Driving the Rise in A-Fib Cases
A-Fib has seen a marked increase over the past decade, driven largely by an aging population and a rise in hypertension, diabetes, and obesity.
Earlier estimates had pegged the number of affected U.S. adults at 3.3 million, a figure that had not been updated for over 20 years. This new study, published in the Journal of the American College of Cardiology, significantly revises these numbers upward.

“Atrial fibrillation doubles the risk of death and is a leading cause of stroke. It also elevates the risks of heart failure, myocardial infarction, chronic kidney disease, and dementia, all of which lower quality of life,” noted Dr. Jean Jacques Noubiap, a postdoctoral researcher at UCSF specializing in global cardiovascular health.
“Fortunately, A-Fib can be prevented, and its adverse effects can be greatly minimized with early detection and appropriate treatment,” he added.
An Urgent Need for Improved Prevention and Management
The surge in cases highlights an urgent need for improved prevention and management strategies. UCSF researchers examined medical records from nearly 30 million adults receiving acute or procedural care in California between 2005 and 2019. Of these, about 2 million were diagnosed with A-Fib, with incidence rates rising from 4.49% of patients between 2005 and 2009 to 6.82% between 2015 and 2019.

When these findings were extrapolated to the national level, researchers estimated a minimum prevalence of 10.55 million cases across the U.S. The study also discovered a demographic shift: patients diagnosed with A-Fib were increasingly younger, less likely to be female, and more prone to have hypertension and diabetes.

A-Fib presents a wide range of complications, from mild symptoms like shortness of breath and dizziness to more severe outcomes such as blood clots, stroke, and heart failure.
People with A-Fib are up to five times more likely to suffer a stroke. These revised estimates provide critical insights that could shape future healthcare strategies, resource distribution, and public health initiatives.
Digital Tools and Future Prevalence Estimates
“Atrial fibrillation is encountered across virtually every medical specialty,” said Dr. Gregory M. Marcus, a cardiologist and electrophysiologist at UCSF Health, and the study’s senior author. “Our data offer concrete evidence that earlier projections vastly underestimated the true prevalence of this condition.”
Moreover, digital tools could reveal an even higher occurrence of A-Fib than currently reported. “With the increasing use of consumer devices designed to detect atrial fibrillation, coupled with advances in safer and more effective treatments, the current figures for A-Fib in healthcare settings may soon be overshadowed by future findings,” Marcus explained.
