CDC Warns: 12 Million Americans May Have AFib by 2030
The Centers for Disease Control and Prevention (CDC) warns that by 2030, nearly 12 million Americans may have atrial fibrillation (AFib), a common heart arrhythmia that disrupts blood flow and increases stroke and heart failure risks.
AFib affects the two upper chambers of the heart, causing irregular heartbeats that can be too fast, too slow, or inconsistent, compared to the average heart rate of 60 to 100 beats per minute. Symptoms can include heart palpitations, chest pain, fatigue, shortness of breath, weakness, and lightheadedness, but some people may not experience any symptoms. Causes range from stress and high blood pressure to heart disease and thyroid disorders. Treatments focus on managing heart rate and rhythm through medications like beta-blockers, calcium channel blockers, and blood thinners, alongside lifestyle changes such as a heart-healthy diet and regular exercise. Different medical organizations, like the European Society of Cardiology (ESC) and the American College of Cardiology (ACC), recommend risk stratification and oral anticoagulation for stroke prevention, with variations in specific drug preferences and procedural interventions. Catheter ablation is strongly recommended for symptomatic patients refractory to drugs, with pulmonary vein isolation being a key strategy.
AFib, the most common heart arrhythmia, can be deadly without proper care. By 2030, nearly 12 million Americans may be affected. Treatments focus on managing symptoms and preventing complications, with various medications and lifestyle changes. Medical organizations emphasize risk stratification and anticoagulation for stroke prevention, with specific recommendations varying slightly.
