Impaired left atrial systolic function and inter-atrial dyssynchrony may contribute to symptoms of heart failure with preserved left ventricular ejection fraction: A comprehensive assessment by echocardiography

LA diastolic and systolic function were significantly impaired, and inter-atrial dyssynchrony was prolonged in patients with HFpEF. Decreased LA systolic function and prolonged inter-atrial dyssynchrony were possibly associated with deteriorated clinical symptoms.
