Faster heart rates were linked to worse LA/LV function and increased clinical events, with optimal function observed at rates below 80 beats/min.
Are faster heart rates associated with worse LA/LV deformational echocardiographic parameters and increased clinical events in patients with atrial fibrillation?
In patients with atrial fibrillation, maintaining a heart rate below 100 beats/min, and ideally below 80 beats/min, is associated with preserved LA/LV deformational function and fewer clinical events.
Absolute Event Rate: 0% vs 0%
Faster heart rates were associated with worse LA/LV functions and increased clinical events independent from baseline risk profiles. Favorable outcomes were found at heart rates below 100 beats/min, with even greater LA/LV function at heart rates below 80 beats/min. The relationship between heart rate and LA/LV function should be considered for patient management and risk stratifications.
