Data is presented as mean ± standard deviation.

Subject groups were compared with Wilcoxon rank-sum test. Significance was defined as p-value < 0.05.

Circ, circumferential; e'SR, peak early diastolic strain rate; ECV, extracellular volume; HFpEF, heart failure with preserved ejection fraction; LV, left ventricular; MI, mass index; MPR, myocardial perfusion reserve; SS, peak systolic strain; SSR, peak systolic strain rate.
