There is little understanding
about the mechanism of left ventricular strain in pulmonary hypertension (PH)
patients at present. In this study, we compared left ventricular strain between
PH patients and the healthy controls. For PH patients with preserved or mildly improved
left ventricular ejection fraction (LVEF), the ventricular strain parameters decreased
compared to the healthy controls. We found that left ventricular myocardial
strain impairment in HP patients is associated with right ventricular overload
of volume or pressure and decreased ejection capacity.
