Main outcome measures: Patients will be followed for 1 year. Nutritional parameters including serum albumin, subjective global assessment, malnutrition-inflammation score, normalised protein nitrogen appearance, fat-free edema-free body mass and anthropometry measurements will be monitored. Systemic inflammatory markers such as serum C-reactive protein and IL-6 will be assayed. Hospitalisation, cardiovascular events, and overall patient survival will also be compared during study period.
