The aim of the present study was to determine whether the addition of an oral nutritional supplement with whey peptides and branched-chain amino acids for cardiac rehabilitation improves cardiopulmonary function, skeletal muscle function, and metabolism in CHF patients.In this randomized, parallel-group comparative pilot study, 20 CHF patients were randomly assigned to the nutrition group (n = 10) or the control group (n = 10). At baseline and 12 weeks, we performed physical examinations, motor function evaluation, clinical laboratory tests, nutritional status assessment, and echocardiography. The primary outcome was exercise tolerance, as determined by the cardiopulmonary stress test (CPX), 6-minute walking test (6MWT), and brain natriuretic peptide (BNP) levels.During follow-up, body weight, body mass index, total muscle mass, and total lean mass did not change significantly in either group. The total fat mass significantly increased in the nutrition group (14.3 ± 5.4 kg versus 16.1 ± 5.5 kg, P < 0.001) but did not change in the control group, and the difference in the changes in total fat mass between groups was significant (−0.26 ± 0.96 kg versus 1.49 ± 0.63 kg, P < 0.001). The peakVO2 and 6-minute walk test (6 MWT) significantly increased in the nutrition group (14.6 ± 3.4 mL/minute/kg versus 15.8 ± 3.8 mL/minute/kg, P = 0.029; 346.9 ± 103.1 m versus 382.7 ± 102.1 m, P = 0.048; respectively) but did not change in the control group. The changes in peakVO2 and 6MWT did not significantly differ between the groups.The oral nutritional supplement for the treatment of CHF was effective for cardiac rehabilitation in terms of fat mass and exercise capacity.The present study demonstrated that oral nutritional supplements with whey peptides and branched-chain amino acid (BCAA) for cardiac rehabilitation in patients with chronic heart failure (CHF) increased fat mass and exercise capacity. We conclude that whey peptides and BCAA supplementation may be a useful treatment for CHF patients.

The Japanese population is rapidly aging because of its long life expectancy and low birth rate; additionally, the number of patients with heart failure (HF) is increasing to the extent that HF is now considered a pandemic. According to a recent HF registry study, Japanese patients with HF have both medical and care-related problems. Although hospitalization is used to provide medical services, and institutionalization is used to provide care for frail older adults, it can be difficult to distinguish between them. In this context, multidisciplinary management of HF has become increasingly important in preventing hospital readmissions and maintaining a patient’s quality of life. Academia has promoted an increase in the number of certified HF nurses and educators. Researchers have issued numerous guidelines or statements on topics such as cardiac rehabilitation, nutrition, and palliative care, in addition to the diagnosis and treatment of acute and chronic HF. Moreover, the Japanese government has created incentives through various medical and long-term care systems adjustments to increase collaboration between these two fields. This review summarizes current epidemiological registries that focus not only on medical but also care-related problems and the 10 years of multidisciplinary management experience in Japanese medical and long-term care systems.

Background:There are no data comparing transcatheter aortic valve implantation (TAVI) with surgical aortic valve replacement (SAVR) outcomes in real clinical practice in Japan.Methods and Results:We combined 2 independent registries, the K-TAVI Registry (a 6-center prospective registry of consecutive patients who underwent TAVI) and the CURRENT AS Registry (a large, 27-center registry of 3,815 consecutive patients with severe aortic stenosis [AS]). In the K-TAVI Registry, 338 patients underwent TAVI with SAPIEN XT balloon-expandable valves from October 2013 to January 2016, whereas in the CURRENT AS Registry 237 patients with severe AS underwent SAVR from January 2003 to December 2011. Propensity score matching was conducted, with final cohort comprising 306 patients. The cumulative 2-year incidence of all-cause death and heart failure (HF) hospitalization did not differ significantly between the TAVI and SAVR groups (13.7% vs. 12.4% [P=0.81] and 7.9% vs 3.9% [P=0.13], respectively). After adjusting for residual confounders, there were no significant differences between the TAVI and SAVR groups in the risk for all-cause death (hazard ratio [HR] 0.74; 95% confidence interval [CI] 0.35–1.58; P=0.43) or HF hospitalization (HR 1.27; 95% CI 0.40–4.59; P=0.69).Conclusions:These findings from 2 independent Japanese registries suggest that the 2-year risk of all-cause mortality and HF does not differ significantly between TAVI and SAVR groups in real-world practice in Japan.

Background:The clinical significance of concomitant mitral regurgitation (MR) has not been well addressed in patients with severe aortic stenosis (AS).Methods and Results:We analyzed 3,815 patients from a retrospective multicenter registry of severe AS in Japan (CURRENT AS registry). We compared the clinical outcomes between patients with moderate/severe MR and with none/mild MR according to the initial treatment strategy (initial aortic valve replacement [AVR] or conservative strategy). The primary outcome measure was a composite of aortic valve-related death or heart failure hospitalization. At baseline, moderate/severe MR was present in 227/1,197 (19%) patients with initial AVR strategy and in 536/2,618 (20%) patients with a conservative strategy. The crude cumulative 5-year incidence of the primary outcome measure was significantly higher in patients with moderate/severe MR than in those with none/mild MR, regardless of the initial treatment strategy (25.2% vs. 14.4%, P<0.001 in the initial AVR strategy, and 63.3% vs. 40.7%, P<0.001 in the conservative strategy). After adjusting confounders, moderate/severe MR was not independently associated with higher risk for the primary outcome measure in the initial AVR strategy (hazard ratio [HR] 1.11, 95% confidence interval [CI] 0.67–1.83, P=0.69), and in the conservative strategy (HR 1.13, 95% CI 0.93–1.37, P=0.22).Conclusions:Concomitant moderate/severe MR was not independently associated with higher risk for the primary outcome measure regardless of the initial treatment strategy.

Background:There is a paucity of data on the sex differences in the prevalence, clinical presentation, and prognosis of aortic stenosis (AS).Methods and Results:A total of 3,815 consecutive patients with severe AS were enrolled in the multicenter CURRENT AS registry between January 2003 and December 2011. The registry included 1,443 men (38%) and 2,372 women (62%). Women were much older than men (79±10 vs. 75±10 years, P<0.0001), and the ratio of women to men increased with age. The cumulative 5-year incidence of all-cause death was significantly higher in men than in women (47% vs. 41%, P=0.003), although women were more symptomatic and much older. The 5-year mortality was similar between men and women at age <65 years (16% vs. 15%, P=0.99), whereas it was significantly higher in men than in women at age ≥65 years (65–74 years, 38% vs. 19%, P<0.0001; 75–84 years, 55% vs. 34%, P<0.0001; ≥85 years: 82% vs. 72%, P=0.03).Conclusions:A large Japanese multicenter registry of consecutive patients with severe AS included a much higher proportion of women than men, with the female:male sex ratio increasing with age. The 5-year mortality rate of women was lower than that of men. Lower 5-year mortality rates in women were consistently seen across all age groups >65 years.
