Background:Evidence for the prognostic value of gait speed is largely based on a single measure at baseline, so we investigated the prognostic significance of change in gait speed in hospitalized older acute heart failure (AHF) patients.Methods and Results:This retrospective study was performed in a cohort of 388 AHF patients ≥60 years old (mean age: 74.8±7.8 years, 228 men). Routine geriatric assessment included gait speed measurement at baseline and at discharge. The primary outcome of this study was all-cause death. Gait speed increased from 0.74±0.25 m/s to 0.98±0.27 m/s after 13.5±11.0 days. Older age, shorter height and lower hemoglobin level at admission, prior HF admission, and higher baseline gait speed were independently associated with lesser improvement in gait speed. A total of 80 patients died and 137 patients were readmitted for HF over a mean follow-up period of 2.1±1.9 years. In multivariate analyses, change in gait speed showed inverse associations with all-cause death (hazard ratio [HR] per 0.1 m/s increase: 0.83; 95% confidence interval [CI]: 0.73 to 0.95; P=0.006) and with risk of readmission for HF (HR: 0.91; 95% CI: 0.83 to 0.99; P=0.036).Conclusions:Short-term improvement in gait speed during hospitalization was associated with reduced risks of death and readmission for HF in older patients with AHF.

The aim of this single-arm pilot study was to determine the effects of whole-body vibration training (WBVT) on endothelial function in elderly patients with cardiovascular diseases, as well as its safety. A total of 20 elderly patients with stable cardiovascular diseases underwent WBVT, which consisted of five static resistance training exercises (squats, wide stance squats, toe-stands, squats + band, and front lunges). The parameters of WBVT included vertical vibrations, 30 Hz frequency, and a 3-mm peak-to-peak amplitude. Each vibration session lasted 30 seconds, with 120 seconds of rest between sessions. Before and after WBVT, the reactive hyperemia peripheral arterial tonometry index (RH-PAT index) and transcutaneous oxygen pressure (tcPO2) were recorded as a measure of endothelial function and peripheral blood circulation. Systolic blood pressure, diastolic blood pressure, heart rate, and arterial oxygen saturation of pulse oximetry (SpO2) were measured at each rest interval as well as before and after WBVT. All patients completed our WBVT protocol without adverse events. The RH-PAT index significantly increased following WBVT (1.42 to 2.06, P < 0.001). There were no significant changes in heart rate (P = 0.777), systolic blood pressure (P = 0.183), diastolic blood pressure (P = 0.925), or SpO2 (P = 0.248) during WBVT. In conclusion, we demonstrated the acute effects of WBVT on endothelial function, with no reports of adverse events. These findings support the need for further randomized controlled studies to investigate the long-term effects of WBVT.

The purpose of this study was to clarify the effect of standing balance training on walking speed (short-term outcome) and cardiac events (long-term outcome) in elderly ischemic heart disease (IHD) patients. This was a retrospective cohort study. Ninety-two elderly (≥ 65 years) IHD patients who underwent an inpatient cardiac rehabilitation program were assigned to two groups: a balance group that received standing balance training in addition to conventional (aerobic and resistance) training and a conventional group. Standing balance was assessed by one-leg standing time and a postural stability index reflecting dynamic balance, and normal walking speed was measured at baseline and hospital discharge. Patients were followed for up to 3 years or until a cardiac event occurred. There were no significant differences in clinical characteristics between the groups. Both groups showed a significant change in normal walking speed from baseline to hospital discharge (P < 0.001, respectively), and normal walking speed was significantly higher in the balance group compared to the conventional group (P = 0.001). The postural stability index improved significantly only in the balance group (P = 0.005). Multivariable analyses using Cox proportional hazards model confirmed that standing balance training (hazard ratio [HR]: 0.408; 95% confidence interval [CI]: 0.162-1.029; P = 0.058) and fast walking speed (HR: 0.362; 95% CI: 0.137-0.957; P = 0.041) were associated with cardiac events. These findings show that standing balance training improves walking speed and reduces cardiac events, and suggests that such training can be an effective intervention for elderly IHD patients.

The purpose of this study was to clarify the acute effects of a single session of stretching exercises on vascular endothelial function and peripheral circulation in patients with acute myocardial infarction. This study evaluated 32 patients (mean age, 66 ± 9 years) who received phase I cardiac rehabilitation after acute myocardial infarction. Five types of stretching exercises were performed on the floor: wrist dorsiflexion, close-legged trunk flexion, open-legged trunk flexion, open-legged lateral trunk bending, and cross-legged trunk flexion. Each exercise entailed a 30-second stretching followed by a 30-second relaxation, and was repeated twice. Low- and high-frequency components (LF and HF) of heart rate variability (LF, 0.04-0.15 Hz; HF, 0.15-0.40 Hz) were analyzed, and HF and LF/HF were used as indices of parasympathetic and sympathetic nervous activities, respectively. Reactive hyperemia peripheral arterial tonometry (RH-PAT) index was measured and used as a parameter for vascular endothelial function. Transcutaneous oxygen pressure (tcPO2) on the right foot and chest was also measured, and the Foot-tcPO2/Chest-tcPO2 ratio was used as a parameter for peripheral circulation. The HF, RH-PAT index, and Foot-tcPO2/Chest-tcPO2 ratio were significantly higher after the exercises than before (P < 0.05, P < 0.01, and P < 0.05, respectively). There was no significant difference in the LF/HF ratio measured before and after stretching exercises. These findings demonstrate that stretching exercises improve vascular endothelial function and peripheral circulation in patients with acute myocardial infarction.
