BACKGROUND The SHOCK Registry prospectively enrolled patients with cardiogenic shock complicating acute myocardial infarction in 36 multinational centers. METHODS Cardiogenic shock was predominantly attributable to left ventricular pump failure in 884 patients. Of these, 276 underwent percutaneous coronary intervention (PCI) after shock onset and are the subject of this report. RESULTS The ...

Cardiogenic shock remains the major cause of death among patients with all types of acute coronary syndromes. Thus, there is a growing interest in the identification of patients who are at risk for developing cardiogenic shock, in the exploration of different therapeutic approaches to preventing its development, and in the improvement of outcome when it occurs. This article reviews the aetiolog...

OBJECTIVES The purpose of this study was to determine the characteristics and outcomes of patients with acute myocardial infarction (MI) complicated by cardiogenic shock due to predominant right ventricular (RV) infarction. BACKGROUND Although RV infarction has been shown to have favorable long-term outcomes, the influence of RV infarction on mortality in cardiogenic shock is unknown. METHODS W...

Clinical and pathologic data were correlated in 22 patients with cardiogenic shock and 10 "control" patients who died suddenly after infarction without shock. A pathologic technique of ventricular mapping allowed quantification of recent as well as old infarction. Total left ventricular (LV) damage averaged 51% (range 35-68%) in the shock patients and 23% (range 14-31%) in the control group. Sh...

Cardiogenic shock is a syndrome characterized by a low cardiac output, elevated left ventricular filling pressure (usually greater than 18 mm Hg) and arterial hypotension (commonly less than 80mm Hg systolic). The commonest cause is extensive left ventricular damage resulting from myocardial infarction and this has a poor prognosis. Other causes, which may be surgically correctable and so have ...

The survival of subjects with postmyocardial infarction cardiogenic shock treated with intra-aortic balloon pumping (IABP) differs significantly among various reports. Differences in the criteria for IABP application and in the timing of its initiation have been considered as the main reasons for variations in survival. This study examines whether the way patients in cardiogenic shock are treat...

A 62 years old lady, nondiabetic, mild hypertensive on non-pharmacological measures, presented with alteration in consciousness of 2 hours duration. There was no history of pain in chest, dyspnea, sweating, fever, loose motion and vomiting; had not suffered from such episode in the past. On examination, she was in cardiogenic shock. Immediately O2 inhalation, intravenous normal saline, inotrop ...
