ObjectiveTo analyze the nutritional status and its influencing factors in patients with chronic heart failure(CHF), and provide the reference for clinical targeted intervention.

MethodsA total of 196 patients with CHF were investigated using the general condition questionnaire, Chinese version of multi-dimensional fatigue scale, hospital anxiety and depression scale, social support rating scale, cardiac insufficiency quality of life scale, heart failure patients comprehensive self-care ability assessment scale and MNA-HF micro-nutrition evaluation scale.

ResultsThe MNA-HF micronutrient score of patients with CHF was (17.25±4.36) points, the self-care ability, quality of life of cardiac dysfunction and social support scores in patients with CHF were positively correlated with the MNA-HF micro-nutrition score(P < 0.01), and the fatigue was negatively correlated with the total score of MNA-HF micro-nutrition evaluation scale(P < 0.01).The results of stratified regression showed that the family average monthly income, type of medical insurance, course of disease, ability of self-care and quality of life were the main influencing factors of MNA-HF micro-nutrition in patients with CHF(P < 0.05), which could explain the 46.9% variation in nutritional evaluation.

ConclusionsThe nutritional status of patients with CHF needs to be further improved, which is related to the monthly income of family, type of medical insurance, course of disease, self-care ability and quality of life.In the future nursing research, the nutritional status of patients with CHF can be improved by paying more attention to the patients with low income and low reimbursement rate, improving their self-care ability and quality of life to reduce the clinical adverse outcomes and improve the prognosis of patients.
