Abstract
IBARRA-SARLAT, Maribel; FUENTES-LARA, Elma I.; SANCHEZ-BANUELOS, Cecilia. and NUNEZ-ENRIQUEZ, Juan C.. Correlation between NT-proBNP levels and the maximun vasoactive-inotropic score in the first 24 hours post-intervention of cardiac surgery. Arch. Cardiol. Méx. [online]. 2019, vol.89, n.4, pp.376-381. Epub Jan 12, 2021. ISSN 1665-1731. https://doi.org/10.24875/acm.19000017.
Introduction:
The clinical utility of brain natriuretic peptide (NT-proBNP) as a prognostic marker in pediatric patients with heart failure is controversial. The maximum vasoactive inotropic score at 24 h after cardiac surgery in pediatric patients is an important predictor of morbidity and postoperative mortality.
Objective:
To determine if there is a correlation between the serum levels of NT-proBNP and the maximum vasoactive inotropic score at 24 hours after cardiac surgery in pediatric patients seen in the Intensive Care Unit.
Material and methods:
An analytical cross-sectional study. A Spearman correlation analysis (rs) was performed between the serum level of NT-proBNP and the maximum inotropic score both taken at 24 hours postoperatively. A value of p less 0.05 was considered statistically significant.
Results:
40 patients were included, 52.5% to the male sex, 72.5% were older than 1 year of age at the time of surgery. A low correlation (rs = 0.26) was found between the serum levels of NT-proBNP and the maximum vasoactive inotropic score at 24 hours, this correlation was not statistically significant (p = 0.09).
Conclusions:
To our understanding, the present study is the first to investigate whether there is a correlation between these markers, so our results could set an important precedent that marks the beginning of multiple investigations in our critically ill patients in order to establish new diagnostic, prognostic and therapeutic approaches.
