[Cross-sectional survey of preoperative nutritional status of cardiac surgery patients in southwest China].

At present, the incidence of preoperative malnutrition in patients undergoing cardiac surgery is high in southwest China. The incidence of malnutrition in patients with basic diseases, long term-valvular disease, low TP, low Alb and anemia before operation is higher, and the incidence of malnutrition is hidden in women. The course of disease of women is longer than that of men at the time of treatment, and malnutrition is more likely to occur. The attending physicians should pay attention to the above groups. It is necessary to establish a standardized individualized nutritional intervention program and apply it to actual clinical diagnosis and treatment, so as to ultimately improve the prognosis of patients undergoing cardiac surgery and increase the benefits of patients in treatment.
