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 [[therapy|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 [[medical history|history]] and [[physical examination]], including [[blood pressure]] measurement, followed by an [[EKG]], [[echocardiography]], [[chest x-ray]] and collection of [[blood]] samples for evaluation. An [[ECG|electrocardiogram]] may be useful in distinguishing cardiogenic shock from other types of [[shock]], such as [[septic shock]] or [[neurogenic shock]]. The [[chest x-ray]] is an important [[diagnostic]] image tool that in patients with [[left ventricular failure]] may show: [[pulmonary edema]], [[pulmonary]] [[vascular]] redistribution, enlarged hila, [[kerley B lines]] and bilateral [[pleural effusions]]. 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.<ref>{{Cite book  | last1 = Longo | first1 = Dan L.

Overview

The chest x ray will show pulmonary edema, pulmonary vascular redistribution, enlarged hila, kerley's B lines, and bilateral pleural effusions in patients with left ventricular failure. In contrast, a pneumonia may be present in the patient with septic shock.Chest x-ray provides information on cardiac size and pulmonary congestion and may suggest alternative pathogeneses such as aortic dissection, pericardial effusion, pneumothorax, esophageal perforation, or pulmonary embolism. The test enables clinicians to confirm the position of the endotracheal tube and the position of supportive devices, including temporary pacing wires.

Chest X-ray

Although not an ideal method to diagnose cardiogenic shock, the chest x-ray may provide important information such as:[1][2]
