Key result
Moderate-severe malnutrition was associated with an increased risk of left ventricular remodeling compared to absent-mild malnutrition (12.9% vs. 9.5%; OR 1.69, 95% CI 1.32-2.16).
Why the study?
Malnutrition increases heart failure risk and left ventricular remodeling drives heart failure progression, but the association between nutritional status and left ventricular remodeling is not well known.
Does moderate-severe malnutrition increase the risk of left ventricular remodeling?
Observational (n=7,217)
No
Does moderate-severe malnutrition increase the risk of left ventricular remodeling?
Moderate-severe malnutrition, assessed by the CONUT score, is independently associated with a 69% increased risk of left ventricular remodeling.

OBJECTIVES: Malnutrition is associated with increased incidence of heart failure (HF). Left ventricular (LV) remodeling is one of the most important processes in the occurrence and evolution of HF. However, the association between nutritional status and LV remodeling is not well known. The study aimed to investigate the association between malnutrition and LV remodeling. DESIGN: The study was a retrospective observation study. SETTING AND PARTICIPANTS: We included patients from the registry of Cardiorenal Improvement study from January 2007 to December 2018 at Guangdong Provincial People's Hospital. MEASUREMENTS: The primary endpoint was LV remodeling, defined as an absolute decrease in LV ejection fraction ≥10% after discharge compared with baseline. Nutritional status was assessed by the Controlling Nutritional Status (CONUT) score. Eligible patients were divided into absent-mild malnutrition group (CONUT score ≤4) and moderate-severe malnutrition group (CONUT score >4). Univariable and multivariable logistic regression was performed to verify the association between malnutrition and left ventricular remodeling. RESULTS: A total of 7,217 patients (mean age 61.3±10.5 years, 71.7% male) were included in the final analysis, among which 712 (9.9%) had LV remodeling. The incidence of LV remodeling in moderate-severe malnutrition group was significantly higher than that in absent-mild malnutrition group (12.9% vs. 9.5%, p=0.002). In multivariable logistic regression, moderate-severe malnutrition group was significantly associated with 1.69-fold increased risk of LV remodeling after adjusting confounders (OR: 1.69, CI: 1.32-2.16). Similar results were observed in subgroup stratified by age, gender, and coronary artery disease. CONCLUSION: Nearly one eighth of patients were classified as moderate-severe malnutrition, 12% of whom had LV remodeling. Moderate-severe malnutrition was associated with 69% increased risk of LV remodeling. Further studies are needed to prospectively evaluate the nutrition-oriented managements on outcomes in LV remodeling.

Li et al. (2022) conducted an observational in Left ventricular remodeling (n=7,217). Moderate-severe malnutrition (CONUT score >4) vs. Absent-mild malnutrition (CONUT score ≤4) was evaluated on Left ventricular remodeling, defined as an absolute decrease in LV ejection fraction ≥10% after discharge compared with baseline (OR 1.69, 95% CI 1.32-2.16, p=0.002). Moderate-severe malnutrition was associated with an increased risk of left ventricular remodeling compared to absent-mild malnutrition (12.9% vs. 9.5%; OR 1.69, 95% CI 1.32-2.16).
