Abstract
BACKGROUND AND PURPOSE: In Romania, robust data about the prevalence of obesity and heart failure are lacking, especially in the elderly; therefore, this study aims to analyze the profile of overweight and obese patients aged >65 years admitted to a Romanian hospital for worsening heart failure, and also their risk in the presence of comorbidities. PATIENTS AND METHODS: . The Charlson Comorbidity Index (CCI) was calculated to evaluate the severity of comorbidity, with a score ranging from 2 (only heart failure present and age >65 years) to 30 (extensive comorbidity). RESULTS: NT-proBNP values are negatively correlated with BMI only in patients with HFpEF. Creatinine clearance (p=0.0166), the presence of atrial fibrillation (p=0.0095) and NYHA functional class were independent predictors of increased NT-proBNP values. CCI score is negatively correlated with NT-proBNP values in patients with HFmrEF (r= -0.448, p=0.009) and HFpEF (r= -0.273, p=0.043). The CCI risk was not significantly different between the three groups. CONCLUSION: Elderly heart failure patients with overweight or obesity have particular characteristics in terms of NT-proBNP values and presence of comorbidities. In the studied population, NT-proBNP levels were strongly influenced by renal function, NYHA functional class, the presence of atrial fibrillation and left ventricular ejection fraction.
