Effect of comorbid heart failure assessed by plasma B-type natriuretic peptide level on the activities of daily living in patients with hospitalization-associated disability after aspiration pneumonia.

Abstract

We investigated the effects of comorbid heart failure on rehabilitation outcomes in patients with hospitalization-associated disability after aspiration pneumonia(AP). This study included 134 patients with hospitalization-associated disability after AP. Patients were classified into heart failure (B-type natriuretic peptide (BNP) ≧100pg/ml, n = 39) and non-heart failure (BNP < 100pg/ml, n = 95) groups, and the rehabilitation outcomes of both groups were compared. Rehabilitation effectiveness was lower in heart failure group than in non-heart failure group (21.1 ± 22.6% vs 36.2 ± 30.8, p < 0.01). The rate of independent walking at discharge in heart failure group (28.2%) was significantly lower than in non-heart failure group (53.7%). Multiple linear regression analysis revealed that age, male, handgrip strength, quadriceps strength, functional oral intake scale, Mini Nutritional Assessment Short Form, and BNP were significantly associated with rehabilitation effectiveness. Results suggest that comorbid heart failure has a negative impact on rehabilitation outcomes in patients with hospital-associated disability after AP.
