Abstract

Objectives: Investigation of the relationship between blood lactate levels at admission and some clinical and laboratory parameters of patients with acute heart failure with reduced ejection fraction without cardiogenic shock. Study subjects: Patients diagnosed with acute heart failure with reduced ejection fraction without cardiogenic shock treated at the Cardiology Institute, Bach Mai Hospital from May 2020 to June 2021. Research Methods: Cross-sectional descriptive. Results and conclusions: 88 study patients (mean age 64,57 ± 14,42 years, 70,5% male) had an average blood lactate concentration at admission of 1,80 ± 0,71 mmol /l, the lowest and highest values ​​are 0,7 and 4,4 mmol/l, respectively, the interquartile range from 25% to 75% is 1,2 and 2,3 mmol/l, respectively. Blood lactate concentration at admission was correlated with heart rate and respiratory rate at admission with r coefficients of 0,225 and 0,303, respectively. There was no correlation between the blood lactate concentration at admission and the concentration of NT-proBNP, troponin T at admission and left ventricular systolic function EF.
