This hypoperfusion causes multiple organ dysfunction and damage which classifies cardiogenic shock a medical emergency. In the past, cardiogenic shock had a poor prognosis. However, currently approximately half of the people that go into cardiogenic shock survive (National Heart, Lung, and Blood Institute [NHLBI], 2011). Cardiogenic shock, according to Werden et al. (2012), is the most common cause of death from an acute myocardial infarction (AMI) and has a chance of mortality from thirty percent to eighty percent. Infarction-related cardiogenic shock (ICS) complicates approximately five to ten percent of acute myocardial infarctions (AMI) and remains the leading cause of death in patients hospitalized from an AMI (Kolte et al., 2014). Kolte et al. (2014) also states that the incidence of cardiogenic shock is higher in patients over the age of seventy-five, and has higher prevalence in women, Caucasians, Asians, and Pacific islanders. This paper will discuss the pathophysiology, clinical manifestations, tools used to diagnose, and therapeutic management of cardiogenic shock. Pathophysiology Cardiogenic shock is commonly caused by myocardial infarction but can also be caused from valvular insufficiency, pericardial tamponade, tension pneumothorax, and large pulmonary emboli. Cardiogenic shock is comprised of
