Cardiogenic shock is a condition of systemic tissuehypoperfusion due to heart muscle incapacity to provideadequate output for organism needs 6. The shock is cardiogenicwhen the primary cause is heart dysfunction. The clinicaldiagnosis of cardiogenic shock is made in the presenceof hypotension (systolic blood pressure (SBP) <90mmHg or30mmHg below the basal value) and evidence of tissuehypoperfusion, such as oliguria, cyanosis, cold limbs, andalterations in the consciousness level. Persistence of theshock status after correction of myocardial and extracardiacfactors that contribute to the reduction of tissue perfusion,such as hypovolemia, arrhythmias, hypoxia, metabolic andacid-base balance disorders, confirm the diagnosis ofcardiogenic shock. When invasive hemodynamic monitoringis available, diagnosis is made if the following alterationsare found 4 (the following values vary in the medical
