Résumé
The effects of cardiac rehabilitation (CR) on long-term prognosis of cardiovascular disease (CVD) are well known. However, the effect of CR on frail CVD patients has not been fully addressed. This study consisted of 89 CVD patients with their age ≥65 years old (68 males, 75 ± 6 years), who participated in the outpatient CR program for 3 months. All the patients underwent cardiopulmonary exercise testing and the physical frailty was assessed using the Japanese Version of the Cardiovascular Health Study Standard before and after CR. Based on the assessment of frailty before CR, the patients were divided into the following two groups: frailty group (n = 23) and non-frailty group (n = 66: robust in 10 and pre-frail in 56 patients). In the frailty group, 20 patients (87%) improved from frail status after CR, and usual walking speed, maximal grip strength, and lower extremity strength were significantly improved (1.06±0.20 vs. 1.20±0.18 m/sec, p<0.001; 21.7 ± 5.5 vs. 23.6 ± 6.3 kg, p<0.01; 0.37±0.09 vs. 0.43±0.11 kgf/kg, p = 0.001, respectively), but peak VO Short-term CR could obtain the improvement of the physical function, providing the prerequisite step for possibly following improvement of exercise capacity in elderly CVD patients with frailty. It may be inferred that longer duration of CR would be needed to obtain the improvement of exercise capacity in these patients, being the future consideration to be determined.

BACKGROUND
The effects of cardiac rehabilitation (CR) on long-term prognosis of cardiovascular disease (CVD) are well known. However, the effect of CR on frail CVD patients has not been fully addressed.
METHODS
This study consisted of 89 CVD patients with their age ≥65 years old (68 males, 75 ± 6 years), who participated in the outpatient CR program for 3 months. All the patients underwent cardiopulmonary exercise testing and the physical frailty was assessed using the Japanese Version of the Cardiovascular Health Study Standard before and after CR. Based on the assessment of frailty before CR, the patients were divided into the following two groups: frailty group (n = 23) and non-frailty group (n = 66: robust in 10 and pre-frail in 56 patients).
RESULTS
In the frailty group, 20 patients (87%) improved from frail status after CR, and usual walking speed, maximal grip strength, and lower extremity strength were significantly improved (1.06±0.20 vs. 1.20±0.18 m/sec, p<0.001; 21.7 ± 5.5 vs. 23.6 ± 6.3 kg, p<0.01; 0.37±0.09 vs. 0.43±0.11 kgf/kg, p = 0.001, respectively), but peak VO
CONCLUSION
Short-term CR could obtain the improvement of the physical function, providing the prerequisite step for possibly following improvement of exercise capacity in elderly CVD patients with frailty. It may be inferred that longer duration of CR would be needed to obtain the improvement of exercise capacity in these patients, being the future consideration to be determined.
