The prevalence of atrial fibrillation (AFib), a common cardiovascular condition in the United States, is notably higher than previously thought. This revelation highlights the necessity for improved prevention and treatment methods. AFib is characterized by a rapid, irregular heartbeat that can result in stroke or sudden death if left untreated. According to a 2024 study published in the Journal of the American College of Cardiology, the current national prevalence of AFib is estimated to be at least 10.5 million adults, significantly higher than earlier estimates of 3.3 million.

A significant number of individuals with atrial fibrillation remain unaware of their condition as they do not exhibit symptoms. Typical symptoms include an irregular heartbeat, heart palpitations, lightheadedness, shortness of breath, fatigue, and chest pain. The U.S. Preventive Services Task Force advises screening for adults without symptoms or other risk factors starting at age 50. Those with risk factors such as high blood pressure and diabetes might need earlier screening.

Khaled Mansour, M.D., FACC, from Lake Norman Medical Group emphasized: “Atrial fibrillation can be effectively managed through lifestyle changes, medication, and in some cases surgical procedures.” He further stressed the importance for adults to understand factors increasing their risk for AFib and to consult with doctors about managing these risks. For some individuals this could mean increased physical activity and adopting a heart-healthy diet; others may require clinical intervention.

High blood pressure accounts for one in five cases of AFib. Other contributing factors include aging, obesity, diabetes, heart failure, sleep apnea, alcohol use and smoking. People with AFib face a four to five times higher risk of stroke compared to those without it; strokes related to AFib tend to be more severe.

Dr. Mansour also stated: “Untreated AFib can lead to severe repercussions for both patients and their families.” He urged those at high risk or experiencing symptoms to undergo screening using tools like an electrocardiogram—a non-invasive test detecting irregular heart rhythms—alongside comprehensive physical examinations.

For patients at high risk for AFib regular wellness checks with primary care physicians are recommended along with discussions on concerns and potential further screenings.
