Objectives: This study aimed to evaluate cardiac function in elderly inpatients admitted to a recovery phase rehabilitation ward. N-terminal pro-B-type natriuretic peptide (NT-proBNP) was statistically analyzed, along with other laboratory and demographic variables. Methods: Laboratory parameters included NT-proBNP, serum albumin, hemoglobin (Hb), l ow-density lipoprotein cholesterol, hemoglobin A1c, and estimated glomerular filtration rate (eGFR). In addition, a number of medications and trends in the use of cardiovascular agents were examined. Results: Four hundred and fifty-seven patients were admitted throughout the year 2017 (188 men and 269 women, aged 83 ±10.1 years). The number of patients with NT-proBNP levels of more than 125, 400, and 900 pg/mL were 347 (75.9%), 204 (44.6%), and 109 (23.9%), respectively. The percentage of patients that had been treated for hypertension, diabetes mellitus, and hypercholesterolemia were 51.8%, 20.5%, and 18.0%, respectively. N-terminal pro-B-type natriuretic peptide positively correlated with age (p=0.003), and negatively with albumin (p<0.0000) and with Hb (p=0.0000). Multiple regression analysis of NT-proBNP with age, albumin, eGFR, Hb, low-density lipoprotein cholesterol, and number of medications as independent variables revealed significant negative correlation only with albumin (p<0.0000) and eGFR (p<0.0000) independently. Conclusions: These results indicate that 3 out of 4 elderly inpatients in the recovery phase of rehabilitation are affected by chronic congestive heart failure, and management of nutrition is essential for prevention and progression of heart failure in this group.
