More attention should be paid to the influence of malnutrition on chronic limb threatening ischemia

Abstract

Chronic limb threatening ischemia (CLTI) is a severe condition of peripheral artery disease with high amputation and mortality. Pain and infection cause insufficient nutrient intake and protein loss in CLTI patients,while malnutrition is very prevalent in patients with CLTI and associated with poor prognosis.More and more studies have shown that malnutrition increases the risk of amputation and mortality,delays the time of wound healing.Moderate and severe malnutrition are independent risk factors for amputation and mortality in CLTI patients undergoing surgical or endovascular revascularization.Nutritional screening tools such as Geriatric nutritional risk index,Mini Nutritional Assessment and Controlling nutritional status can help to stratify patients with nutritional risk.Identification of patients with nutritional risk and nutritional intervention can improve the prognosis of CLTI patients.
