The logistic regression analysis was conducted only for patients with hypertension (with and without HFpEF). LA, left atrial; OR, odds ratio; εs, total strain; εa, active strain; εe passive strain; SRs, peak positive strain rate; SRa, peak late negative strain rate; SRe, peak early negative strain rate; SD, standard deviation; HFpEF, heart failure with preserved ejection fraction.
