Heart failure and chronic kidney disease in a registry of internal medicine wards

Abstract Background The aim of the present study was to evaluate the association between heart failure (HF) and chronic kidney disease (CKD) in tertiary care centers using the clinical records of patients enrolled in internal medicine departments. Patients and methods We used the clinical records of 1380 elderly patients to identify patients with a history of HF and CKD using admission ICD codes and glomerular filtration rate (GFR) formulas. Magnitude and strength of such associations were investigated by univariable and multivariable analysis. Results Of the 1380 patients enrolled, 27.9% had HF (age 80 ± 7, BMI 27 ± 6 kg/m 2 ) and 17.4% CKD (age 81 ± 7, BMI 26.8 ± 6 kg/m 2 ). Both groups were significantly older ( P P P P P P P P 2 increase OR 1.15, P P P Conclusion HF on admission is strongly associated with CKD, older age, BMI, and SI. These data focus the value of epidemiological studies such REPOSI in identifying and monitoring multimorbidity in elderly.
