Key result
Atrial fibrillation is associated with an increased risk for all-cause mortality and heart failure progression in patients with left ventricular systolic dysfunction.
Why the study?
Does the presence of atrial fibrillation increase the risk of mortality and heart failure progression in patients with left ventricular systolic dysfunction?
Does the presence of atrial fibrillation increase the risk of mortality and heart failure progression in patients with left ventricular systolic dysfunction?
Atrial fibrillation in patients with left ventricular systolic dysfunction is associated with disease progression and increased mortality, specifically from pump failure.
AF in LVSD may warrant closer monitoring for progression; leaves open whether rhythm control modifies mortality.
The presence of atrial fibrillation in patients with asymptomatic and symptomatic left ventricular systolic dysfunction is associated with an increased risk for all-cause mortality, largely explained by an increased risk for pump-failure death. These data suggest that atrial fibrillation is associated with progression of left ventricular systolic dysfunction.
