Introduction:

currently, risk factors are looked for to predict results in emergency medicine. The prognosis indexes have been widely applied to heart failure, with uneven results.

Objectives:

to test the leuko-glycaemic index as mortality indicator in heart failure, as well as to calculate the cut-off value.

Material and methods:

a retrospective, longitudinal analytical study was carried out with all the patients who entered the Emergency Intensive Care Unit of the Military Hospital “Carlos J. Finlay” because of decompensated heart failure, from January 2017 until June 2017, and fulfilled the inclusion and exclusion criteria.

Results:

the average age was 79±12 years. Global mortality was around 29 %. The sample was composed by 17 women and 14 men. The error rate in mortality prediction by leuko-glycaemic index is only 5.6 %. The area below the ROC curve is 0,995; IC 95 % (0,979;1); it is evidenced a cut-off point in 1934; therefore, leuko-glycaemic index result higher than this value has a sensibility of 88.9 % and a specificity of 100 % to detect possible deceases.

Conclusions:

leuko-glycaemic index may be an element to take into account in this prognosis. It has a high sensibility and specificity in detecting patients at risk of dying due to heart failure.
