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.
