Objective: To determine causes, diagnostic criteria, treatment and mortality of cardiogenic shock complicating coronary acute syndrome (CSCCAS), at the Instituto Nacional del Corazón Lima - Peru. Material and methods: Observational - descriptive (case series) study of secondary sources was conducted on patients with CSCCAS. To select patients we used key words: cardiogenic shock, intraaortic balloon pumping (IABP), myocardial infarction plus death. Data of clinic charts was analyzed in SPSS program. Results: We got 24 patients, 20 of them had echocardiographic study and 70% showed left ventricular dysfunction (LVD) as a cause of cardiogenic shock owing to coronary acute syndrome (myocardial infarction) and the rest were mechanical complications. 95% filled clinical criteria (including hypotension or signs of end organ hypoperfusion); 11 patients had hemodynamic study and all of them filled hemodynamic criteria. Treatment consisted on vasopressors in 95.8% of patients, inotropics in 66.7%, IABP in 50%. 13 patients had coronary angiographic study and 69.2% of them were revascularized. All the patients died. Conclusions: LVD was the main cause of CS. Diagnosis was predominantly clinical. Medical treatment were used in the majority of cases. Our results were similar to other studies except in mortality that was higher (100%). (Rev Med Hered 2008;19:138-144).
