[Influence of age in short and long term prognostic of ischemic cardiogenic shock]

Abstract

Objective: To compare the prognosis during hospitalization and maximum follow-up of 4 years in patients with myocardial infarction complicated with cardiogenic shock.

Method: Prospective observational study practiced in a coronary Care Unit managed by cardiologists. We included patients with myocardial infarction complicated with cardiogenic shock who received early coronary revascularization. Patients were divided into two groups: older than 75 years (group A) and lower (group B), and we compared the evolution during hospitalization and maximum follow-up of 4 years. Primary end point was mortality rate in the maximum follow-up of 4years. Secondary end point was mortality rate during hospitalization.

Results: Ninety-seven patients were included, 45% Group A. Patients of Group B were mostly men (81% vs. 57%; P=.014), diabetics (48% vs. 21%; P=0.006), and smokers (39.6% vs. 5%). Mortality rate during hospitalization was higher in Group A (54.5%) vs. 30.2% in Group B (P=.022). Mortality rate during follow-up (primary variable) was 73% in Group A vs. 38% in Group B (P=.007).

Conclusions: Myocardial infarction complicated with cardiogenic shock in elderly patients is an entity with high mortality during hospitalization and continues to worsen during long term follow-up.
