Pairwise comparisons of continuous data performed with analysis of variance using Tukey HSD.

p<0.05 compared to patients with normal diastolic function

^ψ

p<0.05 compared to patients with mild diastolic function.

^ξ

p<0.05 compared to patients with moderate/severe diastolic function. Data are mean ± SD or numbers with percentages in parentheses.

^**

Wall motion score index was the same at rest and exercise as patients with ischemia were excluded.
