Longitudinal systolic dysfunction may be present in DHF despite preserved LVEF; hypothesis-generating for HF as a systolic-diastolic continuum.
Is left ventricular systolic function, measured in the long axis, abnormal in patients with diastolic heart failure compared to normal controls?
Tissue Doppler imaging reveals that patients with diastolic heart failure and preserved LVEF have underlying longitudinal systolic dysfunction, suggesting a continuum of systolic impairment rather than isolated diastolic dysfunction.
