Figure 4 Reduced Atrial Systolic Reserve in HFpEF Patients

The effect of isometric handgrip exercise on late diastolic (A') annular tissue velocity in patients with HFpEF (n = 21) and asymptomatic HLVH subjects (n = 25). Unlike HLVH subjects, HFpEF patients had minimal increases in A' with handgrip-exercise. Data shown are mean ± SEM. *Between group ANOVA. Abbreviations as in Figure 1.
