Arrhythmia-free survival is indeed survival of the fittest

(Elsevier) In a new study, investigators report that patients undergoing atrial fibrillation (AF) ablation, who are physically fit before the procedure, have a much higher chance of benefiting from the procedure and remaining in normal sinus rhythm. Less fit patients are rehospitalized more often, continue to use antiarrhythmic therapies longer, and have higher death rates than fitter patients. Their results appear in Heart Rhythm.
