WebMultiple regression showed correlation of torsion with preload (EDV), afterload (ESV), and contractility (PSP; r = 0.67). Furthermore, there was a close linear relationship between torsion and stroke volume (SV) and ejection fraction (EF) during load alteration, but torsion during dobutamine infusion was greater than expected for the extent of ... WebDobutamine is an adrenergic agonist and first-line inotropic. Dobutamine is used for cardiogenic shock and associated hypotension.
