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 people with atrial fibrillation had no prior knowledge of the condition before being diagnosed. The nationwide online survey of 1,200 participants, including 770 patients with AFib and 430 caregivers, was conducted between January and March 2025 and assessed awareness of the condition along with motivations and barriers to treatment.

Atrial fibrillation is a quivering or irregular heartbeat that can lead to blood clots, stroke, heart failure and other heart-related complications. According to the latest statistics from the American Heart Association, the heart rhythm disorder affects over 6 million people in the U.S., and that number is expected to double by 2030. The condition increases stroke risk by up to 5 times, making early identification and treatment critical for stroke prevention.

Dr. José Joglar, American Heart Association volunteer and professor of cardiac electrophysiology at UT Southwestern Medical Center in Dallas, explained that "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." He emphasized that "It's important for people to understand their risk factors, recognize potential symptoms and have regular conversations with their health care professional. Early detection and proactive management can make a life-saving difference."

The research findings reveal significant gaps in public knowledge about AFib and highlight areas where increased awareness is essential to promote earlier recognition and diagnosis. AFib patients reported experiencing an average of three symptoms before receiving a diagnosis, underscoring the need to recognize early warning signs. Symptoms can vary widely or be completely absent, with many people associating AFib primarily with a racing or irregular heartbeat. However, other symptoms like shortness of breath, fatigue, dizziness, chest pain or fainting may occur.

While anyone can develop AFib, risk increases with age and is higher among people with uncontrolled high blood pressure, Type 2 diabetes, overweight, those who have had a prior heart attack or have a family history of the condition. The American Heart Association provides resources for support and connection with others through their online community at MyAFibExperience.org. Additional information about AFib signs, symptoms and management is available at Heart.org/AFib.

Despite the challenges of an AFib diagnosis, the condition is manageable and treatable with the right care plan. Collaborating with a health care team helps patients understand their specific type of AFib and develop a personalized treatment approach that may include medication, procedures and lifestyle changes such as weight management, increasing physical activity, quitting smoking and managing conditions like high blood pressure to support long-term health.
