Introduction: Cardiogenic Shock (CS) is a complication infrequent of acute myocardial Infarction (MI) associated with a poor prognosis. The invasive procedures are a new and important intervention that tend to reduce of mortality.

Purpose: Evaluate the characteristics of patients admitted at Cardiology Interventional Laboratory of the Foundation Clinic Valle del Lili. Determine in-hospital outcomes of patients with acute MI with CS depending type of intervention.

Design: Historic Cohort.

Site: Fundación Clínica Valle del Lili

Materials and Methods: A review of the databases of the Cardiology Interventional Laboratory and Intensive Care Unit within 1994-1999. The cases with acute MI with CS were included.

Results: Among 1250 interventional procedures at Cardiology Interventional Laboratory, 576 patients were admissed with acute MI: 18 patients had CS at admission. Other 18 patients had CS complicating a acute IM initial. All patients with acute MI complicated by CS were treated with primary PTCA. 69.4% were male (n=25), range age 34-84 years (mean 62.3 ± 10.4).
The overall mortality was 55.5% (20/36). Mortality rate in the patients that were admissed with CS 7/18 and mortality rate in the patients with CS after initial treatment (38.9%vs75%, p < 0.05).

Conclusions: The cardiogenic shock is an important cause of mortality after acute MI. These findings suggest that early reperfusion with invasive procedures reduce the mortality risk in comparison of the patients that were admissed with acute MI and without CS.
