What is nonvalvular atrial fibrillation?
Nonvalvular atrial fibrillation (AFib) is a type of irregular heart rhythm that occurs in the absence of significant heart valve disease or an artificial heart valve. It involves disorganized electrical signals in the upper chambers of the heart (atria), which can lead to a fast or erratic heartbeat. This condition can increase the risk of stroke and other heart-related complications.Who might be a candidate for a diagnosis of nonvalvular AFib?
• Patients with atrial fibrillation not caused by a mechanical heart valve or severe mitral valve disease.• Individuals with high blood pressure, heart failure, diabetes, or advanced age.
• Those with no structural valve abnormalities on imaging but who experience irregular heart rhythms.
• Patients who have AFib triggered by lifestyle or metabolic factors, such as alcohol or thyroid disorders.
What to expect during evaluation for nonvalvular AFib
• Diagnosis is typically confirmed with an electrocardiogram (ECG or EKG).• Additional tests may include echocardiogram, blood work, or continuous heart monitoring.
• Management can involve medications to control rate or rhythm and reduce stroke risk.
• Decisions about treatment often depend on age, symptoms, and stroke risk factors.
What are the risks of nonvalvular AFib?
• Increased risk of stroke due to blood clots forming in the atria.• Potential for heart failure if the rhythm remains uncontrolled.
• Ongoing fatigue, palpitations, or shortness of breath.
• Some treatments (medications or procedures) carry their own risks, such as bleeding or procedural complications.
Recovery from nonvalvular AFib treatment
• Recovery depends on the treatment path—medications, cardioversion, or ablation.• Blood thinners may be continued long-term to reduce stroke risk.
• Patients may need to monitor heart rate and symptoms regularly.
• Follow-up includes repeat heart rhythm monitoring and medication adjustments.
• Cardiac rehab or lifestyle coaching may support long-term heart health.
