Cardiogenic shock is one of the most challenging emergencies that intensivists must face. Cardiogenic shock is a syndrome that ensues when the heart is unable to deliver enough blood to maintain adequate tissue perfusion. A rigorous determination requires hemodynamic confirmation, with sustained systemic hypotension (systolic arterial pressure < 90 mmHg or mean arterial pressure (MAP) 30 mmHg or more below basal levels), adequate left ventricular (LV) filling pressures (pulmonary artery wedge pressure > 15 mmHg), and a reduced cardiac output (cardiac index < 2.2 1/min/m2) . In clinical practice, the diagnosis of cardiogenic shock is often made prior to such objective confirmation, by the presence of systemic arterial hypotension with evidence of hypoperfusion in the setting of myocardial dysfunction.
