Abstract

Objectives: To describe some clinical, paraclinical and blood lactate levels in 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 were treated at the Cardiology Institute, Bach Mai Hospital from May 2020 to June 2021. Research Methods: Cross-sectional descriptive. Results and conclusions: The average age of 88 study patients was 64,57 ± 14,42 years, 70,5% were male. The cause of heart failure due to coronary artery disease accounted for 62,5%, followed by hypertension (15,9%), cardiomyopathy (11,4%) and valvular heart disease (10,4%). The rate of new-onset heart failure accounted for 13,0%. Clinical features: SBP 126,4 ± 18,55 mmHg, SBP 80,68 ± 12,80 mmHg; heart rate mean 98,57 ± 16,31 beats/min; respiratory rate average 26,80 ± 4,31 times/min; SpO2 TB 92,06 ± 2,41 %; 100% of patients have wet rales; 98,9% dyspnea NYHA III, IV; 30,7% edema of the lower extremities; 29,5% hepatomegaly and 21,6% atrial fibrillation. Paraclinical characteristics: mean ejection fraction EF 27,89 ± 5,81%; average concentration of NT - proBNP 824,13 [377,30; 4138,0] pmol/L; the mean troponin T concentration was 39,81 [6,80; 130,0] ng/L; mean glomerular filtration rate 47,16 ± 20,39 ml/min, average blood lactate concentration 1,80 ± 0,71 mmol/l.
