Left ventricular ejection fraction: morbidity, mortality and use of resources in a cardiac intensive care unit
PDF size: 67.64 Kb.
ABSTRACTObjective: Determine if ejection fraction (FE) has correlation with the morbidity and the use of resources in cardiac surgery.
Design: Cohort study.
Setting: Cardiac surgery ICU of a General Hospital, Mexico City.
Patients: Four hundred-seventeen patients (mean age 54.6 ± 13.7 yrs) admitted to the ICU after cardiac surgery during one year.
Measurements and main results: Demographic, status discharge, EF, morbidity and use of resources were evaluated. Statistical analysis was performed with ANOVA of two ways and χ2. An excellent correlation between EF and mortality, reoperations, acute renal failure, multiorganic dysfunction, cardiorrespiratory arrest, and the use of Swanz-Ganz catheter, intra-aortic ballon counterpulsation, mechanical ventilation, dialysis and blood products was observed.
Conclusion: EF is an useful isolated prognosis marker of morbidity, mortality and use of resources in cardiac surgery.
