Key result
Moderate to severe malnutrition, as defined by the CONUT score, was independently associated with nearly threefold higher odds of left ventricular hypertrophy (OR 2.810) compared to normal nutritional status.
Why the study?
Left ventricular hypertrophy is an important cardiovascular risk marker, and the association between CONUT-defined nutritional status and LVH and reduced LVEF in adults was unclear.
Is poorer nutritional status, assessed by the CONUT score, associated with increased odds of left ventricular hypertrophy and reduced LVEF in adult cardiovascular outpatients?
Cross-Sectional (n=2,066)
No
Is poorer nutritional status, assessed by the CONUT score, associated with increased odds of left ventricular hypertrophy and reduced LVEF in adult cardiovascular outpatients?
Poorer nutritional status, as assessed by the CONUT score, is independently associated with a higher prevalence of left ventricular hypertrophy and reduced ejection fraction in adult outpatients.

Malnutrition by CONUT score was associated with higher LVH odds; leaves open whether nutritional intervention alters remodeling.
Left ventricular hypertrophy (LVH) is an important marker of cardiovascular risk, while malnutrition is common among adults. The Controlling Nutritional Status (CONUT) score is an objective tool for nutritional assessment. This study aimed to investigate the associations of CONUT-defined nutritional status with LVH and reduced left ventricular ejection fraction (LVEF) in adults. This single-center retrospective cross-sectional study included 2066 adults. Nutritional status was classified according to the standard CONUT categories as normal nutrition, mild malnutrition, and moderate/severe malnutrition. Echocardiography was used to assess left ventricular mass index and LVEF, and LVH was defined using sex-specific left ventricular mass index thresholds. Logistic regression analyses were performed to evaluate the associations of CONUT-defined nutritional status with LVH and reduced LVEF. Among the 2066 participants, 1002 (48.5%) had normal nutritional status, 912 (44.1%) had mild malnutrition, and 152 (7.4%) had moderate/severe malnutrition. In the multivariable logistic regression model, both mild malnutrition (odds ratio [OR] = 1.597, 95% confidence interval [CI]: 1.033–2.495; P = .037) and moderate/severe malnutrition (OR = 2.810, 95% CI: 1.445–5.223; P = .002) were independently associated with higher odds of LVH. Moderate/severe malnutrition was independently associated with reduced LVEF (OR = 2.350, 95% CI: 1.259–4.239; P = .006). Poorer CONUT-defined nutritional status was associated with a higher prevalence of left ventricular structural and functional abnormalities. CONUT-defined nutritional status may provide supplementary information for cardiovascular risk stratification.

Yang et al. (2026) conducted a cross-sectional in Left ventricular hypertrophy (n=2,066). Moderate/severe malnutrition (CONUT-defined) vs. Normal nutritional status was evaluated on Left ventricular hypertrophy (LVH) (OR 2.810, 95% CI 1.445-5.223, p=0.002). Moderate to severe malnutrition, as defined by the CONUT score, was independently associated with nearly threefold higher odds of left ventricular hypertrophy (OR 2.810) compared to normal nutritional status.
