Rationale: To analyze and correlate nutritional status using BMI, AC, and CC, and to describe the most prevalent comorbidities in patients undergoing myocardial revascularization (MR) surgery.

Methods: This was a prevalence study based on retrospective data collection of clinical and anthropometric information from 19 patients who underwent MR surgery between January and December 2024 in a private hospital. The parameters analyzed included BMI, AC, and CC, as well as the presence of comorbidities.

Results: The majority of patients were male (94.7%), with a mean age of 62.3 years and an average hospital stay of 17.4 days. The most prevalent comorbidities were systemic arterial hypertension (78.94%), diabetes mellitus (63.15%), and dyslipidemia (52.63%). According to BMI, overweight was the most common classification (36.84%), followed by underweight (21.05%), obesity (21.05%), and normal weight (21.05%). Based on AC, 15.78% presented mild malnutrition, 68.42% were classified as normal, 10.52% as overweight, and 5.26% as obese. Regarding CC, 68.42% were classified as normal and 31.57% as malnourished. When comparing the indicators, BMI showed greater sensitivity in identifying overweight and obesity, whereas AC and CC were more effective in detecting malnutrition—especially CC, which revealed the highest prevalence of nutritional deficit (31.57%).

Conclusion: These findings suggest that BMI alone may underestimate muscle mass loss in patients with chronic comorbidities. The significant presence of comorbidities associated with changes in nutritional status highlights the need for a multidimensional approach in the preoperative assessment of cardiac surgery patients. The combined use of BMI, AC, and CC provides a more accurate understanding of nutritional status and is essential for guiding appropriate nutritional and clinical interventions.
