Abstract:
Objective To observe the effect of recombinant human brain natriuretic peptide(rhBNP) on hemodynamics in patients with severe heart failure.
Methods Totally 52 patients with severe heart failure admitted to the General ICU of Shanghai Pudong Hospital between February 2016 and March 2019 were randomly divided into the control group (n = 26) and rhBNP group (n = 26). Five cases in the control group and 4 cases in the rhBNP group were excluded as they did not meet the standard of case study, so the final control group and rhBNP group respectively included 21 and 22 cases. Both groups were treated with routine drugs and nutritional support in order to treat their primary basic diseases and improve cardiac function. On this basis, patients in the control group were treated with isosorbide dinitrate, while those in the rhBNP group were given rhBNP, all for 5 days. The general data of patients in the two groups were recorded. The hemodynamic indices, such as global ejection fraction (GEF), cardiac index, global end-diastolic volume index (GEDI), systemic vascular resistance index (SVRI), extravascular lung water index (ELWI), mean arterial pressure and central venous pressure, N-terminal pro-brain natriuretic peptide (NT-proBNP) and 24 h urine volume were compared before treatment and 1, 3, 7 d after treatment between the two groups.
Results The differences of GEF, cardiac index, GEDI, SVRI, ELWI, mean arterial pressure, central venous pressure, NT-proBNP and 24 h urine volume before treatment and 1, 3, 7 d after treatment were statistically significant between these two groups (F = 20.864, 8.982, 89.286, 102.485, 43.824, 12.562, 10.189, 123.848, 89.264; all P < 0.05). Further pairwise comparison showed that there were significant differences in GEF, cardiac index, GEDI, SVRI, ELWI, mean arterial pressure and central venous pressure 3, 7 d after treatment, and NT-proBNP and 24 h urine volume 1, 3, 7 d after treatment between the rhBNP group and control group (all P < 0.05). In the rhBNP group, the expression levels of GEF [(20.6 ± 5.2)%, (28.7 ± 5.2)%, (12.2 ± 4.2)%], cardiac index [(2.88 ± 0.36), (3.68 ± 0.42), (2.02 ± 0.46) L·min-1·m-2] 3, 7 d after treatment and the 24 h urine volume [(1 680 ± 220), (1 868 ± 246), (2 198 ± 228), (1 568 ± 248) mL] 1, 3, 7 d after treatment were much higher than those in the same group before treatment, and were highest on 7 d after treatment (all P < 0.05). The expression levels of GEDI [(947 ± 110), (791 ± 110), (1 108 ± 100) mL/m2], SVRI [(2 642 ± 508), (2 218 ± 568), (3 289 ± 510) dyn·sec·cm-5·m2], ELWI [(9.3 ± 2.5), (8.6 ± 2.1), (12.3 ± 2.7) mL/kg], mean arterial pressure [(73 ± 6), (69 ± 5), (80 ± 6) mmHg] and central venous pressure [(8.7 ± 1.4), (7.1 ± 1.3), (12.3 ± 2.1) mmHg] 3, 7 d after treatment, and NT-proBNP [(4 829 ± 326), (3 029 ± 298), (2 006 ± 300), (6 979 ± 469) ng/L] 1, 3, 7 d after treatment of patients in the rhBNP group were much lower than those in the same group before treatment, and were lowest on 7 d after treatment (all P < 0.05).
Conclusion Compared with isosorbide dinitrate, rhBNP can be more effective in improving the hemodynamics and cardiac function of patients with severe heart failure, which is worthy of promotion in ICU.
