Key result
Aggressive rhythm control of atrial fibrillation has the potential to reverse arrhythmia-induced cardiomyopathy, supporting a primary rhythm control strategy in these patients.
Why the study?
Does aggressive rhythm control reverse cardiomyopathy in patients with atrial fibrillation and arrhythmia-induced cardiomyopathy?
Does aggressive rhythm control reverse cardiomyopathy in patients with atrial fibrillation and arrhythmia-induced cardiomyopathy?
Aggressive rhythm control of atrial fibrillation has the potential to reverse arrhythmia-induced cardiomyopathy, a strategy supported by recent guidelines.
Atrial fibrillation (AF) is an increasingly common arrhythmia. As the prevalence of this condition grows, it is becoming clear that it can cause a primary nonischemic cardiomyopathy in the absence of significantly elevated ventricular rates.1 Ruling out other nonischemic processes and distinguishing this condition from tachycardia-induced cardiomyopathy is essential, as aggressive rhythm control of AF has the potential to reverse the cardiomyopathy. The most recent iteration of the American College of Cardiology/American Heart Association/American College of Clinical Pharmacy/Heart Rhythm Society Guideline for Diagnosis and Management of AF supports the role of a primary rhythm control strategy in these patients.
