Abstract: Objective To analyze the status and influencing factors of nutritional risk in patients with chronic heart failure. Methods From December 2019 to December 2023,patients with grade Ⅱ-Ⅳ chronic heart failure admitted to two hospitals in Haikou City were selected for this study. The general information and disease data of patients were collected. The Mini-Nutrition Assessment Special for Heart Failure （MNA-HF） was used to evaluate the nutritional risk of patients. Univariate and multivariate analyses were used to analyze the independent influencing factors of nutritional risk in patients with chronic heart failure. Results A total of 2 135 patients with chronic heart failure were enrolled,of whom 698 （32.69%） had normal nutrition,914 （42.81%） had nutritional risk,and 523 （24.49%） had malnutrition. Multivariate logistic regression analysis showed that age （OR=2.821）,BMI （OR=0.325）,place of residence （OR=0.561）,NYHA cardiac function classification （OR=2.102）,edema （OR=2.494）,activity of daily living （OR=0.536）,eating attitude test score （OR=2.499）,thickness of posterior wall of left ventricle （OR=1.960）,hemoglobin （OR=0.429）,albumin （OR=0.365）,and C-reactive protein （OR=2.106） were associated with nutritional risk in patients with chronic heart failure. Conclusions The risk of malnutrition in patients with chronic heart failure is high,which is affected by individual age,cardiac function,edema,diet,inflammatory state,living style,daily activity ability,and other factors. Clinical attention should be paid to nutritional risk assessment and nutritional intervention in patients with chronic heart failure.
