Controlling Nutritional Status score as a predictor of ventricular arrhythmias in patients with advanced heart failure

Key Result

CONUT-defined malnutrition independently predicts ventricular arrhythmias and all-cause mortality in advanced heart failure patients receiving CRT.

Key Points

The aim is to evaluate whether the CONUT score predicts ventricular arrhythmias and mortality in heart failure patients.
Evaluated CONUT-defined malnutrition in patients with advanced heart failure
Analyzed risk of ventricular arrhythmias and all-cause mortality in CRT recipients
Conducted statistical analysis to determine independent predictors
Malnutrition was identified as a strong predictor of ventricular arrhythmias
CONUT score significantly correlated with increased all-cause mortality
Nutritional assessment improved risk stratification capabilities

Structured PICO

Does CONUT-defined malnutrition predict ventricular arrhythmias and all-cause mortality in patients with advanced heart failure undergoing CRT?

Population

Patients with advanced heart failure undergoing cardiac resynchronization therapy (CRT)

Intervention

Controlling Nutritional Status (CONUT) score assessment for malnutrition

Outcome

Ventricular arrhythmias and all-cause mortalityhard clinical

Nutritional assessment using the CONUT score can enhance risk stratification for ventricular arrhythmias and mortality in patients with advanced heart failure receiving CRT.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

CONUT-defined malnutrition was a strong independent predictor of ventricular arrhythmias and all-cause mortality in CRT recipients. Nutritional assessment may enhance risk stratification in patients with advanced HF undergoing CRT.
