Objectives:

this study aimed to evaluate the relationship of Nutritional Risk Screening 2002 (NRS2002) and in-hospital major adverse cardiac events (MACE) in patients with severe heart failure.

Methods:

an observational study was conducted at the emergency intensive care units (EICU) of Shandong University Qilu Hospital from January 2017 to December 2019. Nutritional screening and assessment were performed at the time of admission to hospital with the NRS2002.

Results:

of the 209 patients included, 16 cases (7.66 %) were not at nutritional risk, and 193 cases (92.34 %) were at risk. Among them, 12 cases (5.74 %) were malnourished, 38 cases (18.18 %) were at high nutritional risk, and 115 cases (55.02 %) were overweight and obese. The differences in prealbumin (PA) and N-terminal B-type natriuretic peptide precursor (NT-proBNP) between the 2 groups were statistically signific ant (p < 0.05). A total of 134 cases (64.12 %) received nutrition treatment support, of which 39 cases (29.10 %) received enteral nutrition (EN), 77 cases (57.46 %) parenteral nutrition, and 18 cases (13.43 %) enteral nutrition combined with parenteral nutrition (EN + SPN) support treatment. In all, 31 cases (54.39 %) reached 100 % of the target dose. Patients in the EN and EN + SPN groups had 37 MACE (64.91 %) and 31 enteral nutrition complications (54.39 %), with differences between the 3 groups being statistically significant (p < 0.05).

Conclusion:

the nutritional risk of patients with severe heart failure is high, and age and heart function are positively correlated with nutritional risk. The complications rate of patients with high nutritional risk is significantly higher than in those with low risk; the higher the nutritional risk, the higher the hospital mortality rate — that is, nutritional risk affects disease outcome.
