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
