preoperative protein-calorie malnutrition
Effect of prehabilitation-related dietary protein intake on quality of recovery after elective cardiac surgery: a randomized controlled trial
Effect of prehabilitation-related dietary protein intake on quality of recovery after elective cardiac surgery: a randomized controlled trial
1. To determine the potential for dietitian guided change in preoperative dietary protein intake levels in malnourished patients scheduled for elective cardiac surgery undergoing nutritional prehabilitation. 2. To evaluate the effect of high-quality dietary protein intake on the quality of recovery after elective cardiac surgery in malnourished patients undergoing nutritional prehabilitation. 3. To evaluate the effect of nutritional prehabilitation on the length of postoperative stay in malnourished patients undergoing elective cardiac surgery. 4. To determine the synergistic effect of preoperative dietary protein intake and physical activity on quality of recovery after elective cardiac surgery in malnourished patients undergoing nutritional prehabilitation.

Ⅳ期
This is a single-center, pragmatic, two-armed, parallel, superiority, blinded randomized controlled trial. Participants will be randomly allocated to either nutritional prehabilitation or usual care (no nutritional prehabilitation) with 1:1 allocation. Block randomization with randomly selected block sizes will be performed.
Due to the nature of the intervention and requirements of informed consent, trial participants were not blinded to the treatment allocation. Study research personnel who collected the follow-up nutritional status and food frequency intake at hospital admission were blinded from the treatment allocation. Outcome assessors were also blinded to the participant’s group allocation.

1. Adults (no age restriction) undergoing elective or non-emergent major to ultra-major cardiac surgery (CABG, valve surgery or combined) 2. MUST>0 or FFMI<17 for men or FFMI<15 for women or SMI<7 for men or SMI<5.7 for women Patients on the elective cardiac surgery waiting list are routinely assessed the Perioperative Medicine Clinic several weeks before the scheduled operation date. After written informed consent, patients will complete the MUST questionnaire and undertake a body composition test using a bioelectrical impedance analysis device (InBody 270, InBodyUSA, Cerritos, CA) to measure FFMI and SMI for study eligibility determination.；
