Atrial fibrillation (AFib) affects 5 million Americans and is the most common type of arrhythmia in the United States. While some people only experience mild symptoms, or none at all, AFib can increase the risk of serious health complications when left untreated.
At Cardiology Specialists of Orange County in Newport Beach and Santa Ana, California, our experienced cardiologists help patients understand and manage their AFib. Here’s what you need to know about this common heart condition and why early treatment matters.
AFib is an arrhythmia, or irregular heartbeat, caused by abnormal electrical signals in the upper chambers of the heart, or the atria. Instead of contracting in a coordinated rhythm, the atria quiver or fibrillate, disrupting the normal flow of blood through the heart.
When blood doesn’t move efficiently, it can pool in the atria, increasing the risk of blood clot formation. These clots can travel through the bloodstream and potentially cause life-threatening complications, including stroke.
Several conditions can contribute to the development of AFib, including:
In some cases, AFib may develop without a clearly identifiable cause.
AFib doesn’t always cause noticeable symptoms. Some people discover they have the condition during a routine medical exam, while others may dismiss symptoms as stress, anxiety, or overexertion.
Common signs and symptoms of AFib include:
Symptoms may occur occasionally, come and go in episodes, or persist continuously depending on the type and severity of AFib.
AFib affects more than heart rhythm; it can have serious consequences for overall cardiovascular health.
One of the biggest concerns is stroke. Because blood can pool in the atria and form clots, people with AFib have a significantly higher risk of experiencing a stroke if a clot travels to the brain.
AFib can also cause the heart to work harder than normal. Over time, this added strain may weaken the heart muscle and contribute to heart failure, a condition in which the heart can no longer pump blood efficiently throughout the body.
Researchers have also identified a possible connection between AFib and cognitive decline. Experts believe that reduced blood flow to the brain, chronic inflammation, and small “silent” strokes that occur without obvious symptoms may increase the risk of memory and thinking problems over time.
The goals of AFib treatment are to restore normal or to control an abnormal heart rhythm, reduce symptoms, and lower the risk of blood clots and stroke. The best treatment for you depends on the severity of your symptoms, how long you’ve had AFib, and the underlying cause.
Treatment options for AFib may include:
Lifestyle changes can also play an important role in managing AFib and supporting long-term heart health. Eating a heart-healthy diet, exercising regularly, maintaining a healthy weight, and controlling conditions such as high blood pressure can help improve outcomes.
Although AFib can increase the risk of serious complications, effective treatment can help you manage the condition and maintain an active and healthy lifestyle. Advances in interventional cardiology have made it possible for many patients to achieve better symptom control and reduce their risk of stroke and heart failure.
