Dietary protein intake in older adults undergoing cardiac surgery.

Background: Older adults undergoing major surgery have increased protein requirements in the postoperative period, but there are limited data describing actual protein intake following cardiac surgery.

Methods And Results: We performed a prospective sub-study within a registry of older adults ≥60 years of age undergoing cardiac surgery at a tertiary care centre. A dietician administered a food frequency questionnaire before surgery and 1-4 months after surgery.
