This study revealed that excessive norepinephrine in pheochromocytoma and paraganglioma was associated with increased blood pressure and LV mass. The LV longitudinal strain was decreasing with increase in blood pressure and LV mass index. The enhanced LV circumferential strain might be the mechanism of compensation to maintain the normal LVEF in these patients.
