The Prognostic Value and Treatment Strategies of Nutritional Status in Heart Failure Patients.

Heart failure is a complex clinical syndrome caused by a variety of reasons leading to abnormal changes in the structure and/or function of the heart, with ventricular systolic and/or diastolic dysfunction, which is a serious manifestation or late stage of various heart diseases. The overall prognosis of patients is poor, and risk assessment of patients with HF is currently a hot topic of research due to the large heterogeneity of etiology, phenotype, and genetic background of HF patients. Besides, the nutritional level and status of HF patients are affected by various aspects. Patients with malnutrition, high saturated fatty acids and cholesterol, low minerals, and other conditions tend to have a poor prognosis. So targeted improvement of the nutritional status of HF patients is important to improve the prognosis and the quality of survival of patients. We use heart failure, nutrition, and diet therapy as the keyword method to summarize the prognostic value of indicators of nutritional status in HF patients, the effects of nutritional status on HF patients with different etiology, and potential treatment strategies for HF patients with different etiology. This review is valuable for understanding the prognostic value of nutritional levels in patients with HF and guiding clinical therapeutic approaches.
