1 prior hospitalization for HF
Left ventricular ejection fraction (LVEF) >40%
End-diastolic interventricular septal wall thickness (IVST) 12 mm

Presence or history of any severe valvular heart disease (obstructive or regurgitant)
A confirmed diagnosis of a non-amyloid infiltrative cardiomyopathy (ie, cardiac sarcoidosis, hemochromatosis), muscular dystrophies, cardiomyopathy with reversible causes, hypertrophic obstructive cardiomyopathy with known genetic etiology, or known pericardial constriction
