ECHOES-X criteria for objective evidence of heart failure

Abnormality	Criteria	Type of heart failure
Left ventricular systolic dysfunction	Ejection fraction 40%	HFREF
Borderline left ventricular systolic dysfunction	Ejection fraction 41–50%	HFREF
Diastolic dysfunction	Diastolic dysfunction defined as E:e′ >13 or E:e′ 8–13 with LV hypertrophy (IVS >1.2 cm) or LA enlargement (>4 cm (males); >3.8 cm (females))	HFPEF
Significant valvular disease	Moderate to severe (grade 2–3)	HFPEF
Atrial fibrillation	Diagnosed on ECG	HFPEF

HFPEF, heart failure with preserved ejection fraction; HFREF, heart failure with reduced ejection fraction; IVS, interventricular septum; LA, left atrium.
