BackgroundPatients with chronic heart failure (CHF) are frequently readmitted to the hospital. Six-minute walk distance (6MWD) is a clinical measure to assess their exercise capacity and prognosis. However, few reports documented whether the 6MWD reflects the exercise capacity and prognosis in elderly CHF patients.PurposeThis study aimed to investigate whether the 6MWD measured at the hospital discharge predicted the readmission due to decompensated CHF in early elderly and late elderly CHF patients.MethodsPatients who were admitted to the hospital were prospectively followed up for 3 years after the discharge, if they had the first hospitalization due to CHF with NYHA III or IV. Consequently, we studied 177 patients (74±6 years, 112 males) and investigated their 6MWD at the discharge and readmission over 3 years. Patients were divided into 2 groupsearly elderly group (65-74 years; n=108) and late elderly group (≥75 years; n=62). We determined significant factors affecting the readmission due to CHF and their cut-off values in the two groups using multivariate logistic regression analysis and the area under the receiver operating characteristics (ROC) curve.Results50 % of early elderly patients and 42 % of late elderly patients were readmitted within 3 year after the discharge. The multivariate logistic regression analysis detected the 6MWD at the discharge as a significant limiting factor for readmission in the two groups (P
