Abstract:
Objective To investigate the role of enteral nutrition (EN) support in the treatment of patients with chronic heart failure. Methods Ninety patients with chronic heart failure (conform to the New York Heart Association (NYHA) cardiac function class Ⅲ-Ⅳ) admitted to Intensive Care Unit (ICU), Cardiology Care Unit (CCU) and Emergency ICU (EICU) of Taizhou First People's Hospital from January 2015 to September 2017 were enrolled, and according to different nutritional methods, they were divided into a control group (rational autonomous diet group) and an observation group (Ruineng enteral nutritional emulsion for EN group), each group 45 cases. Based on the calculation (Harris-Benedict) of individual total energy consumption the control group had a reasonable autonomous diet and Ruineng EN emulsion for EN group. The chang of various nutrition indexes [including body mass index (BMI), serum total protein (TP), albumin (Alb), hemoglobin (Hb), vitamin B12, folic acid, serum iron], inflammatory factors [tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)], and the level of cardiac function index (LVEF) before and after treatment were observed. Results ① Before treatment, vitamin B12 in the observation group was significantly higher than that in the control group (ng/L: 153.3±54.6 vs. 113.4±80.2, P < 0.05), there were no statistical significant differences in other indicators between the two groups (all P > 0.05). ② After treatment, compared with those before treatment, the nutritional indicators and LVEF of both groups were higher, and inflammatory factors were lower, there were statistical significant differences in the other indicators before and after treatment except Hb and IL-6 in the control group and serum iron in the observation group [the control group: BMI (kg/m2) was 20.9±1.8 vs. 19.9±1.2, TP (g/L) was 66.0±2.4 vs. 63.7±1.6, Alb (g/L) was 34.4±3.5 vs. 31.1±2.3, vitamin B12 (ng/L) was 149.5±79.2 vs. 113.4±80.2, folic acid (nmol/L) was 10.0±1.7 vs. 4.6±3.2, serum iron (μmol/L) was 16.5±13.7 vs. 10.4±7.5, TNF-α (ng/L) was 23.8±10.0 vs. 28.3±8.6, LVEF was 0.35±0.14 vs 0.32±0.04; observation group: BMI (kg/m2) was 21.5±1.4 vs. 20.2±1.4, TP (g/L) was 66.5±2.8 vs. 64.3±2.2, Alb (g/L) was 35.8±3.1 vs. 33.3±1.9, Hb (g/L) was 121.4±13.8 vs. 112.9±12.0, vitamin B12 (ng/L) was 201.1±98.6 vs. 153.3±54.6, folic acid (nmol/L) was 15.7±14.4 vs. 8.8±2.8, TNF-α (ng/L) was 20.5±6.3 vs. 25.8±3.0, IL-6 (ng/L) was 209.4±6.5 vs. 220.9±16.9, LVEF was 0.38±0.07 vs. 0.33±0.02, all P < 0.05]. ③ Before and after treatment, the changes of BMI, Hb, vitamin B12, folic acid and IL-6 in the observation group were more significant than those in the control group [BMI (kg/m2): 1.4±0.9 vs. 1.1±0.3, Hb (g/L): 8.6±1.2 vs. 2.7±0.9, vitamin B12 (ng/L): 47.1±1.0 vs. 36.2±0.9, folic acid (nmol/L): 6.8±1.8 vs. 5.5±1.8, IL-6 (ng/L):-10.8±2.3 vs. -1.6±1.0, all P < 0.05]. After treatment, the degree of increase of serum iron in the control group was more significant than that in the observation group (μmol/L: 6.2±0.8 vs. 1.4±0.9, P <0.05), there were no significant differences in the degrees of improvement in TP, Alb and TNF-α between the two groups (all P > 0.05). ④ The difference value of each indicator before and after treatment of the two groups of patients with cardiac grade Ⅲ was more significant than that in the patients with cardiac grade Ⅳ, among the indicators in the control group, Hb, serum iron and IL-6 showed statistical significant differences [Hb (g/L): 3.05±0.42 vs. 2.47±0.84, serum iron (μmol/L): 6.81±0.91 vs. 5.95±1.82, IL-6 (ng/L): -3.87±0.45 vs. -0.53±0.28, all P < 0.05], while in the observation group of patients with cardiac grade Ⅲ and Ⅳ, Alb, Hb, serum iron, IL-6 appeared statistical significant differences [Alb (g/L): 3.41±0.38 vs. 2.27±0.91, Hb (g/L): 9.83±1.44 vs. 8.10±0.98, serum iron (μmol/L): 2.23±0.34 vs. 1.04±0.88, IL-6 (ng/L):-14.11±0.42 vs. -9.45±1.01, all P < 0.05]. Conclusion In the treatment of patients with chronic cardiac failure, simultaneously EN support is given energetically, that can improve the nutrition status of organism, reduce inflammatory reaction and enhance cardiac function; the therapeutic effect of Ruineng EN support is remarkably better than that of the autonomous diet support.
