Overview
Attending to the catastrophic outcome of cardiogenic shock in a very short time span, its diagnosis must be reached as early as possible in order for proper therapy to be started. This period until diagnosis and treatment initiation is particularly important in the case of cardiogenic shock since the mortality rate of this condition complicating acute-MI is very high, along with the fact that the ability to revert the damage caused, through reperfusion techniques, declines considerably with diagnostic delays. Therefore and due to the unstable state of these patients, the diagnostic evaluations are usually performed as supportive measures are initiated. The diagnostic measures should start with the proper history and physical examination, including blood pressure measurement, followed by an EKG, echocardiography, chest x-ray and collection of blood samples for evaluation. The physician should keep in mind the common features of shock, irrespective of the type of shock, in order to avoid delays in the diagnosis. Although not all shock patients present in the same way, these features include: abnormal mental status, cool extremities, clammy skin, manifestations of hypoperfusion, such as hypotension and oliguria, as well as evidence of metabolic acidosis on the blood results. Echocardiography is an important imaging modality for the evaluation of the patient with cardiogenic shock. This test will allow the identification of certain characteristics that, when complemented by a proper medical history and physical examination, will likely prompt to the diagnosis. These may include: poor wall motion, papillary muscle rupture, pseudoaneurysms, ventricular septal defects, among others. The echocardiographic findings may also suggest or rule out a different diagnosis. The test will provide information about the overall hemodynamic status of the heart as well, which may reveal to be vital in order to plan further measures and predict the outcome.[1]
Echocardiography
In recent years noninvasive means of estimating cardiac function have seen their use increased considerably. These methods, such as echocardiography, have helped reducing the use of invasive means, like right heart catheterization, in acute coronary syndrome patients. Echocardiography with Doppler imaging has become common practice in recent years across many institutions, for bedside evaluation of cardiac status, including: overall function, valvular competence and eventual mechanical complications arising from ACS, such as papillary muscle rupture or ventricular septal rupture.[2][3]
