Atrial fibrillation might be conceptualized as a consequence rather than a cause of symptoms of heart failure in patients with exertional dyspnea.
Suggests that atrial fibrillation in patients with dyspnea may be a consequence of underlying occult HFpEF rather than the primary cause of symptoms.
dyspnea exercise heart failure A trial fibrillation (AF) is common in patients with heart failure and preserved ejection fraction (HFpEF). Like people with HFpEF, patients with AF commonly describe exertional dyspnea. Treatments directed at AF are often undertaken by using antiarrhythmic drugs, rate control, or AF ablation with the ultimate goal of improving these symptoms. However, recent data indicate that some patients with apparently lone AF display myocardial abnormalities that persist even when sinus rhythm has been restored, suggesting the coexistence of an underlying cardiomyopathic process. Viewed in this light, AF might be conceptualized as a consequence rather than a cause of symptoms of heart failure.
Reddy et al. (Mon,) conducted a review in Atrial Fibrillation and Heart Failure with Preserved Ejection Fraction. Atrial fibrillation might be conceptualized as a consequence rather than a cause of symptoms of heart failure in patients with exertional dyspnea.
