New research published in the Journal of the American College of Cardiology reveals that Atrial fibrillation (A-Fib) is three times more common in the United States than previously known, affecting an estimated 10.5 million American adults. A-Fib is characterized by an irregular heartbeat and can lead to severe complications such as stroke, heart failure, heart attack, kidney disease, and dementia.
While individuals with atrial fibrillation have an increased risk of heart-related mortality, the condition is treatable and typically not life-threatening. The exact cause of A-Fib remains unknown, but it tends to occur more frequently with age and is prevalent in certain groups with existing cardiovascular conditions.
A recent study conducted by scientists at the University of California analyzed medical records of 30 million adult patients in California from 2005 to 2019, revealing that 2 million individuals had atrial fibrillation. The study also observed an increasing incidence of A-Fib over the years, indicating a rise in prevalence due to factors such as obesity, hypertension, and diabetes.
Symptoms of atrial fibrillation may include irregular and rapid palpitations, chest pain, shortness of breath, and anxiety. Diagnosis can be made through an irregular heartbeat or an electrocardiogram (ECG). Technological advancements, such as smartwatches designed to monitor A-Fib, are aiding in the detection and management of the condition.
What are the signs of atrial fibrillation?
Dr. Hugh Calkins, a prominent cardiologist, emphasized the importance of recognizing symptoms of atrial fibrillation for early detection and treatment. Individuals experiencing symptoms are encouraged to seek medical advice for proper evaluation and management of the condition.
