3. Cardiogenic Shock Cardiogenic shock (CS) is a life-threatening medical condition characterized by inadequate tissue perfusion due to cardiac dysfunction, and it is most common caused by acute myocardial infarction. It is the state initiated by acute hypo perfusion state, leading to tissue hypoxia and vital organ dysfunction. It is the condition in which heart suddenly cant pump enough blood to meet the body’s needs, failure of the heart muscle, also called as severe heart attach. 1/30/2018 3

Causes of Cardiogenic Shock Cardiac valve insufficiency/damage Myocardial stenosis Septal defects Myocardial infarction Arrhymias (disturbed electrical activity of heart) Myocarditis or overwhelming infections (Bacteria)- may risk to organ-liver, kidney failure and eventually COMA. 1/30/2018 4

Clinical Presentations General: Anxiety, restlessness, fatigue (hypoxia), altered mental state- decreased cerebral perfusion and subsequent hypoxia BP: Hypotension - decrease in cardiac output Pulse: A rapid, thready, pulse Skin: Cool, clammy, and mottled skin (cutis marmorata ) - to vasoconstriction and subsequent hypoperfusion of the skin. Raised JVP : due to increased jugular venous pressure Oliguria: hypoperfusion- (low urine output) due to insufficient renal perfusion if condition persists. Respiratory rate: Rapid and deeper respirations (hyperventilation) due to sympathetic nervous system stimulation and acidosis Pulmonary edema : due to fluid back-up in the lungs - insufficient pumping of the heart 1/30/2018 5
