CARDIOLOGISTS FREQUENTLY CALLED TO EVALUATE PATIENTS IN”SHOCK” REVIEW: ISSUES SURROUNDING “NON-CARDIOGENIC SHOCK” ETIOLOGY AND CURRENT TREATMENT OF SHOCK DUE TO STEMI
SHOCK IS DIAGNOSED BASED ON CLINICAL, HEMODYNAMIC, AND BIOCHEMICAL FINDINGS
Systemic arterial hypotension is usually present, . SHOCK IS DIAGNOSED BASED ON CLINICAL, HEMODYNAMIC, AND BIOCHEMICAL FINDINGS Systemic arterial hypotension is usually present, .
SHOCK IS DIAGNOSED BASED ON CLINICAL, HEMODYNAMIC, AND BIOCHEMICAL FINDINGS Systemic arterial hypotension is usually present, Clinical signs of tissue hypoperfusion, CUTANEOUS (skin that is cold and clammy, vasoconstricted and cyanoticsis, RENAL (urine output of <0.5 ml per kilogram of body weight per hour), and neurologic (altered mental state, obtundation, disorientation, confusion .
SHOCK IS DIAGNOSED BASED ON CLINICAL, HEMODYNAMIC, AND BIOCHEMICAL FINDINGS 3. Elevated lactate levels, indicating abnormal cellular oxygen metabolism
SHOCK MECHANISMS Four pathophysiological mechanisms which are not mutually exclusive: Hypovolemia
SHOCK MECHANISMS Four pathophysiological mechanisms which are not mutually exclusive: Hypovolemia Cardiogenic factors
SHOCK MECHANISMS Four pathophysiological mechanisms which are not mutually exclusive: Hypovolemia Cardiogenic factors Obstruction to cardiac filling
SHOCK MECHANISMS Four pathophysiological mechanisms which are not mutually exclusive: Hypovolemia Cardiogenic factors Obstruction to cardiac filling Distributive factors
SHOCK MECHANISMS Four pathophysiological mechanisms which are not mutually exclusive: Hypovolemia (from internal or external fluid loss), Cardiogenic factors (valvular, myocardial, arhythmia) Obstruction to cardiac filling (PE, tamponade, pneumothorax) Distributive factors (sepsis, anaphylaxis)
SHOCK FREQUENCY Vincent J, De Backer D. N Engl J Med 2013;369:1726-1734.
SHOCK DIAGNOSIS CARDIAC OUTPUT CVP DISTRIBUTIVE ↑↑ HYPOVOLEMIC ↓ CARDIOGENIC ↑ OBSTRUCTIVE
SHOCK Hypovolemia, Cardiogenic and Obstructive are characterized by low cardiac output, inadequate oxygen transport. Distributive shock, decreased systemic vascular resistance and altered oxygen extraction. cardiac output is high, Multiple mechanisms: ie pancreatitis; hypovolemia, sepsis and myocardial depression
SHOCK TREATMENT Correction of etiology Ventilatory support Fluid rescusitation Vasoactive Norepinephrine Inotropic Dobutamine Mechanical support IABP ECMO

At 30 days there was no significant overall benefit Conclusions: In pts with myocardial infarction who had cardiogenic shock due to left ventricular dysfunction. At 30 days there was no significant overall benefit of early revascularization 2. Early revascularization resulted in lower mortality from all causes at six months. 3. Recommend that early revascularization be strongly considered for patients with acute myocardial infarction complicated by cardiogenic shock. Hochman JS et al. N Engl J Med 1999;341:625-634.
