Key result
Rapid ventricular response in males, prosthetic valves, TR, and RV dysfunction predict LVEF reduction during AF/AFL.
Why the study?
What are the clinical and echocardiographic predictors of left ventricular systolic dysfunction in patients with atrial fibrillation or flutter?
What are the clinical and echocardiographic predictors of left ventricular systolic dysfunction in patients with atrial fibrillation or flutter?
Male sex, rapid ventricular response, prosthetic valves, and right-sided heart dysfunction are predictors of LVEF reduction in patients with AF/AFL.
May flag high-risk AF patients for closer monitoring; hypothesis-generating and requires prospective validation before practice change.
In 'real-world' experience, male patients with rapid ventricular response during paroxysmal AF or AFL are more prone to LVEF reduction. Patients with prosthetic valves are also at risk for LVEF reduction during AF/AFL. Finally, tricuspid regurgitation and right ventricular dysfunction may indicate relatively long-standing AF with an associated reduction in LVEF.
