Cardiogenic shock is considered an [[emergency]] and irrespectively to the [[therapeutic]] approach, the target goal of any [[therapy]] is prompt [[revascularization]] of [[ischemic myocardium]]. This should be achieved in the shortest timespan possible. There are two major categories of treatment for cardiogenic shock, the ''medical/conservative approach'' and the ''interventional approach''. The ideal [[therapy|treatment]] combines both mechanisms, in which medical therapy, after restored filling pressures, allows [[hemodynamic|hemodynamical]] stabilization of the patient, until interventional methods, that contribute to the reversal of the process leading to the [[shock]] state, may performed. The interventional approach may include [[PCI]] or [[coronary artery bypass graft surgery]] ([[CABG]]) and in both techniques the goal is not only reperfusion of the occluded [[coronary artery]], but also prevention of [[coronary artery|vessel]] reoclusion. If there is no access to a [[cardiac catheterization]] facility, nor the possibility of transferring the patient to one within 90 minutes, then immediately [[thrombolytic therapy]] should be considered.<ref name="NgYeghiazarians2011">{{cite journal|last1=Ng|first1=R.|last2=Yeghiazarians|first2=Y.|title=Post Myocardial Infarction Cardiogenic Shock: A Review of Current Therapies|journal=Journal of Intensive Care Medicine|volume=28|issue=3|year=2011|pages=151–165|issn=0885-0666|doi=10.1177/0885066611411407}}</ref> Other important factors to increase the chances of a better [[outcome]] are: [[mechanical ventilation]], in order to improve [[tissue]] [[oxygenation]], and close monitoring of the [[therapeutic]] dosages, particularly of [[vasoactive]] drugs, since these have been associated with excess [[mortality]] due to [[toxicity]] effects.<ref name="pmid17387132">{{cite journal| author=TRIUMPH Investigators.

Overview

The most common causes of cardiogenic shock remain MI. The American College of Cardiology and American Heart Association, in collaboration with the Canadian Cardiovascular Society, have issued an update of the 2004 guideline for the management of patients with ST-segment elevation myocardial infarction. The American Academy of Family Physicians endorses and accepts this guideline as its policy. Early recognition and prompt initiation of reperfusion therapy remains the cornerstone of management of ST-segment elevation myocardial infarction. Aspirin should be given to symptomatic patients. Beta blockers should be used cautiously in the acute setting because they may increase the risk of cardiogenic shock and death. The combination of clopidogrel and aspirin is indicated in patients who have had ST-segment elevation myocardial infarction. A stepped care approach to analgesia for musculoskeletal pain in patients with coronary heart disease is provided. Cyclooxygenase inhibitors and nonsteroidal anti-inflammatory drugs increase mortality risk and should be avoided. Primary prevention is important to reduce the burden of heart disease. Secondary prevention interventions are critically important to prevent recurrent events in patients who survive. Available data indicate that the development of shock after hospital admission with acute MI is as common as cardiogenic shock on presentation. Because of the > 50% mortality associated with both of these conditions, the most favorable means of making an impact on shock mortality is to prevent its development. Therefore, effective therapy for shock must include a prevention strategy. In the GUSTO study, 70% of patients who developed cardiogenic shock after admission were Killip class I on admission, and of the remaining patients most were in Killip class II with only mild heart failure. For this reason, other clinical clues must be used to recognize patients at high risk for developing shock. The development of tachycardia or evidence of peripheral vasoconstriction are early clinical signs ofthe "preshock" state. Data from the Secondary Prevention Reinfarction Israel Nifedipine Trial (SPRINT) study") suggest that the presence of diabetes, history of angina, peripheral vascular or cerebrovascular disease, prior MI, and female gender are all risks for development of shock in Killip class I patients with acute infarction. These investigators estimated a 35% probability of developing shock if all six of these factors were present on admission. In addition to these clinical factors obtained from the history and physical examination, diagnostic studies such as early two-dimensional echocardiography may be helpful in evaluating selected patients. In a consecutive series of over 80 patients, Gibson etnl. stratified patients with acute MI into two groups: those with asynergy in the infarct zone only and those with asynergy in the infarct zone plus a remote zone. They found that the latter group had a significantly higher incidence of cardiogenic shock (34 vs. 8%, p = 0.01), as well as higher rates of death, reinfarction, and Killip class progression than patients with asynergy in the infarct zone only. It is likely that all of the above information is helpful in identifying patients with triple-vessel coronary artery disease in an otherwise low-risk clinical group (i.e., patients without heart failure on admission).

Primary prevention

Attending to the definition of primary prevention, namely the group of measures that aim to avoid the development of a disease state (preventive measures) and considering the fact that left ventricular failure following acute MI is the most common cause of cardiogenic shock, these patients should undergo primary prevention of myocardial infarction.[1]The ACC/AHA guideline stresses the importance of primary prevention. The consensus opinion is that a risk factor assessment for CHD should be performed every three to five years in all patients. Risk factors include smoking, diabetes, hypercholesterolemia, hypertension, family history, age, and sex. In patients with two or more major risk factors, calculation of a 10-year coronary artery disease risk score is recommended to assess the need for primary prevention.3 The risk score can also be an effective tool to start a dialogue with patients about lifestyle change.The American College of Cardiology (ACC) and American Heart Association (AHA) have updated their 2004 guideline1 for the management of patients with ST-segment elevation myocardial infarction (STEMI). The updated guideline was developed in collaboration with the Canadian Cardiovascular Society and published in 2008. The American Academy of Family Physicians endorses and accepts this guideline as its policy. This review summarizes the key recommendations as they apply to the prevention of coronary heart disease (CHD), acute management of STEMI, and secondary prevention of recurrent events.
