Dobutamine is preferred over Dopamine in cardiogenic shock because of its effects related to
Dobutamine is a catecholamine with b-1 and b-2 adrenergic agonist propeies which help improve myocardial contractility. In patients with cardiogenic shock due to decompensated hea failure,dobutamine decreases left ventricular end-diastolic pressure and raises blood pressure by increasing cardiac output.

Better cardiac stimulation
Less peripheral Vasoconstriction
Lower risk of cardiac Arrythymia
More CNs stimulation
