Gastrointestinal symptoms are among the most common symptoms of heart failure (HF), the end stage of various cardiovascular diseases. The 2014 Expert Consensus on Nutritional Prescription for Cardiovascular Disease states that approximately 40% HF patients are at risk of malnutrition, which is an independent risk factor for death in HF patients and a critical contributor to the occurrence and development of cachexia. Once cardiac cachexia develops, the disease becomes irreversible. Therefore, the nutritional problems of the patients with chronic heart failure(CHF)have attracted increasing attention of the scholars both at home and abroad in recent years, and the studies on nutritional intervention have been growing. This article reviews and summarizes the interactions between malnutrition and CHF, the clinical application of nutritional status screening and evaluation tools for CHF patients, envisioning the clinical modes and tools of nutritional intervention for CHF patients with a view to providing clinical guidance for improving the prognosis of CHF patients.
