Nutritional Status Assessment Tools in Cardiovascular Patients

Area of Science:

• Cardiology
• Nutritional Science
• Medical Diagnostics

Background:

• Malnutrition is prevalent and underrecognized in cardiovascular disease (CVD) patients.
• It is linked to adverse outcomes like prolonged hospitalization, readmissions, and mortality.
• Traditional metrics like body mass index (BMI) are often inadequate for malnutrition detection in CVD due to factors like fluid retention and obesity.

Purpose of the Study:

• To critically review current nutritional assessment tools for cardiovascular disease (CVD) populations.
• To discuss the applicability and limitations of various screening and diagnostic instruments in the context of CVD.
• To propose an optimized approach for nutritional status assessment in CVD patients.

Main Methods:

• Review of established nutritional screening tools (NRS 2002, MNA, MUST, SGA, CONUT).
• Examination of diagnostic frameworks, including the Global Leadership Initiative on Malnutrition (GLIM) criteria.
• Evaluation of body composition assessment methods, such as bioelectrical impedance analysis (BIA) and phase angle (PA).

Main Results:

• Existing nutritional assessment tools exhibit variable diagnostic performance and applicability in CVD.
• CVD-specific pathophysiological features (inflammation, fluid imbalance, medications) impact tool accuracy.
• The GLIM criteria offer a standardized approach but need further validation in cardiology.

Conclusions:

• A multimodal strategy involving initial screening and confirmatory assessment is recommended for CVD patients.
• Utilizing GLIM criteria alongside objective measures of muscle mass and cellular integrity is suggested.
• Clinicians must consider tool-specific limitations and CVD-related challenges when interpreting nutritional assessments.
