New Research Reveals 62% of AFib Patients Unaware of Condition Before Diagnosis

New consumer patient research from the American Heart Association reveals that 62% of atrial fibrillation patients had no prior knowledge of their condition before receiving a diagnosis. The nationwide online survey, conducted by The Olinger Group between January and March 2025, involved 1,200 participants including 770 AFib patients and 430 caregivers, assessing awareness levels and treatment barriers for this serious heart rhythm disorder.

Atrial fibrillation affects over 6 million people in the United States, with projections indicating this number will double by 2030. The condition increases stroke risk by up to five times and can lead to blood clots, heart failure, and other cardiovascular complications. According to Dr. José Joglar, professor of cardiac electrophysiology at UT Southwestern Medical Center and chair of the 2023 AFib guidelines, "This projected rise is driven by several factors, including the growing prevalence of high blood pressure, a major risk factor for AFib, as well as increasing rates of diabetes, obesity and an aging population."

The research findings reveal significant gaps in public knowledge about AFib symptoms and risk factors. Patients reported experiencing an average of three symptoms before diagnosis, with many unaware that symptoms extend beyond irregular heartbeat to include shortness of breath, fatigue, dizziness, chest pain, or fainting. Risk factors include age, uncontrolled high blood pressure, Type 2 diabetes, overweight status, prior heart attack, and family history of the condition.

Despite the serious nature of AFib, the condition is manageable and treatable with proper medical care. Treatment options include medication, medical procedures, and lifestyle changes such as weight management, increased physical activity, smoking cessation, and blood pressure control. The American Heart Association emphasizes that early detection and proactive management can make a life-saving difference in stroke prevention and overall cardiovascular health.

During AFib Awareness Month in September, the organization is promoting resources for patients and caregivers, including their online community at MyAFibExperience.org where individuals can find support and connect with others facing similar challenges. Additional information about AFib signs, symptoms, and management strategies is available at Heart.org/AFib.

The research was sponsored by the American Stroke Association, a division of the American Heart Association, with funding support from the HCA Healthcare Foundation, which also serves as a national sponsor of the Together to End Stroke® initiative and AFib Awareness Month. The findings underscore the critical need for increased public education about AFib recognition and the importance of regular health care professional consultations for early detection and effective management of this growing public health concern.
