Prevalence of Atrial Fibrillation on the Rise Due to Lifestyle Factors, Aging Population
2/5/2025
LAS CRUCES, NM – The prevalence of one of the most common cardiovascular conditions in the U.S. is significantly higher than previously estimated, underscoring the need for better prevention and treatment strategies. Atrial fibrillation (AFib) is a rapid, irregular heartbeat that can lead to stroke or sudden death if untreated. A 2024 study in the Journal of the American College of Cardiology estimates the current national prevalence of AFib to be at least 10.5 million adults, compared to previous estimates of 3.3 million adults.
Many people with atrial fibrillation don’t know they have it and don’t have symptoms. However, common symptoms of AFib include an irregular heartbeat, heart palpitations, lightheadedness, shortness of breath, fatigue and chest pain. The U.S. Preventive Services Task Force recommends adults without symptoms of atrial fibrillation or other risk factors should be screened at aged 50. Those with risk factors such as high blood pressure and diabetes may need to be screened sooner and anyone experiencing symptoms should contact their doctor.
“Atrial fibrillation is highly treatable with lifestyle modifications, medication, and in some cases surgical procedures,” said Craig Cannon, a board-certified cardiologist at MountainView. “It is important for adults to understand underlying factors that may increase their risk of AFib and talk with their doctor about addressing those factors. For some, it may be exercising more and eating a heart healthy diet, but others may also need clinical intervention.”
One in five cases of AFib can be attributed to high blood pressure. Other risk factors include advancing age, obesity, diabetes, heart failure, sleep apnea, alcohol use and smoking. The risk of stroke is four to five times higher in people with AFib, and AFib-related strokes tend to be more severe than strokes caused by other factors. In addition, AFib can lead to heart attack, heart failure and sudden cardiac arrest.
“Left untreated, AFib can have devastating consequences for patients and their families, so it is important to get screened if you are in a high-risk group or have symptoms,” added Dr. Cannon. “The most common screening tool is an electrocardiogram, a non-invasive test that can detect irregular heart rhythms, along with a thorough physical examination.”
Patients who are at high risk for AFib should maintain regular wellness checks with a primary care physician and talk with their doctor about their concerns and further screening. To make an appointment today, visit MountainViewDocs.com.
