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.

Background: There is a paucity of data on the effect of optimal intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) compared with standard PCI or coronary artery bypass grafting (CABG) in patients with multivessel disease.Methods and Results: The OPTIVUS-Complex PCI study multivessel cohort was a prospective multicenter single-arm study enrolling 1,021 patients undergoing multivessel PCI including the left anterior descending coronary artery using IVUS aiming to meet the prespecified criteria for optimal stent expansion. We conducted propensity score matching analyses between the OPTIVUS group and historical PCI or CABG control groups from the CREDO-Kyoto registry cohort-3 (1,565 and 899 patients) fulfilling the inclusion criteria for this study. The primary endpoint was a composite of death, myocardial infarction, stroke, or any coronary revascularization. In the propensity score-matched cohort (OPTIVUS vs. historical PCI control: 926 patients in each group; OPTIVUS vs. historical CABG control: 436 patients in each group), the cumulative 1-year incidence of the primary endpoint was significantly lower in the OPTIVUS group than in the historical PCI control group (10.4% vs. 23.3%; log-rank P<0.001) or the historical CABG control group (11.8% vs. 16.5%; log-rank P=0.02).Conclusions: IVUS-guided PCI targeting the OPTIVUS criteria combined with contemporary clinical practice was associated with superior clinical outcomes at 1 year compared with not only the historical PCI control, but also the historical CABG control.

Background:We sought to explore the effects of previous heart failure (HF) hospitalization on mortality in patients hospitalized for acute decompensated HF (ADHF) in a large Japanese contemporary observational database.Methods and Results:We prospectively enrolled consecutive patients with ADHF in 19 participating hospitals between October 2014 and March 2016. Of 4,056 patients, 1,442 patients (35.4%) had at least 1 previous HF hospitalization (previous hospitalization group), while 2,614 patients (64.5%) did not have a history of HF hospitalization (de novo hospitalization group). Patients with previous hospitalization were older and more often had comorbidities such as anemia, and renal failure than those without. The cumulative 1-year incidence of all-cause death was significantly higher in the previous hospitalization group than in the de novo hospitalization group (28% vs. 19%, P<0.001). After adjusting confounders, the excess risk of the previous hospitalization group relative to the de novo hospitalization group for all-cause death remained significant (HR, 1.28; 95% CI: 1.10–1.50, P=0.001). The excess risk was significant in patients without advanced age, anemia, or renal failure, but not significant in patients with these comorbidities, with significant interaction. Increase in the number of hospitalizations was associated with an increased risk for mortality.Conclusions:In a contemporary ADHF cohort in Japan, repeated hospitalization was associated with an increasing, higher risk for 1-year mortality.

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:Decreased skeletal muscle mass index (SMI) is a major complication of severe chronic heart failure (HF), but no appropriate indices have been developed to predict decreased SMI.Methods and Results:We enrolled patients with a structural heart disease or history of HF and collected body composition and blood sample data, including serum amino acid concentration. On multivariate logistic regression analysis and receiver operating characteristic curve analysis, serum branched-chain amino acid (BCAA) concentration was a significant predictor of decreased SMI at 1-year follow-up.Conclusions:Serum BCAA concentration at baseline was significantly associated with decreased SMI at 1-year follow-up.

Background: Clinical practice guidelines strongly recommend optimal medical therapy (OMT), including lifestyle modification, pharmacotherapy, and exercise-based cardiac rehabilitation (CR), in patients with stable ischemic heart disease (SIHD). However, the efficacy and safety of CR in patients with SIHD without revascularization remain unclear.Methods and Results: The Prospective Registry of STable Angina RehabiliTation (Pre-START) study is a multicenter, prospective, single-arm, open-label pilot study to evaluate the efficacy and safety of CR on health-related quality of life (HRQL), exercise capacity, and clinical outcomes in Japanese patients with SIHD without revascularization. In this study, all patients will undergo guideline-based OMT and are encouraged to have 36 outpatient CR sessions within 5 months after enrollment. The primary endpoint is the change in the Seattle Angina Questionnaire-7 summary score between baseline and the 6-month visit; an improvement of ≥5 points will be defined as a clinically important change. Secondary endpoints include changes in other HRQL scores and exercise capacity between baseline and the 6-month visit, as well as clinical outcomes between enrollment and the 6-month visit.Conclusions: The Pre-START study will provide valuable evidence to elucidate the efficacy and safety of CR in patients with SIHD and indispensable information for a subsequent randomized controlled trial. The study was registered with the University Hospital Medical Information Network (UMIN) Clinical Trials Registry (ID: UMIN000045415) on April 1, 2022.

Background: The clinical benefits of neurohormonal antagonists for patients with heart failure (HF) with mid-range and preserved ejection fraction (HFmrEF and HFpEF) are uncertain.Methods and Results: This study analyzed 858 consecutive patients with HFmrEF (EF: 40–49%) or HFpEF (EF ≥50%), who were hospitalized for acute HF, and who were discharged alive, and were not taking angiotensin-converting enzyme inhibitors (ACE)-I/ angiotensin II receptor blockers (ARB) or β-blockers at admission. The study population was classified into 4 groups according to the status of prescription of ACE-I/ARB and β-blocker at discharge: no neurohormonal antagonist (n=342, 39.9%), ACE-I/ARB only (n=128, 14.9%), β-blocker only (n=189, 22.0%), and both ACE-I/ARB and β-blocker (n=199, 23.2%) groups. The primary outcome measure was a composite of all-cause death or HF hospitalization. The cumulative 1-year incidence of the primary outcome measure was 41.2% in the no neurohormonal antagonist group, 34.0% in the ACE-I/ARB only group, 28.6% in the β-blocker only group, and 16.4% in the both ACE-I/ARB and β-blocker group (P<0.001). Compared with the no neurohormonal antagonist group, both the ACE-I/ARB and β-blocker groups were associated with a significantly lower risk for a composite of all-cause death or HF hospitalization (HR: 0.46, 95% CI: 0.28–0.76, P=0.002).Conclusions: In hospitalized patients with HFmrEF and HFpEF, starting both ACE-I/ARB and a β-blocker was associated with a reduced risk of the composite of all-cause death or HF hospitalization compared with patients not starting on an ACE-I/ARB or β-blocker.

Background:Optimal intensity is unclear for P2Y12receptor blocker therapy after percutaneous coronary intervention (PCI) in real-world clinical practice.Methods and Results:From the CREDO-Kyoto Registry, the current study population consisted of 25,419 patients (Cohort-2: n=12,161 and Cohort-3: n=13,258) who underwent their first PCI. P2Y12receptor blocker therapies were reduced dose of ticlopidine (200 mg/day), and global dose of clopidogrel (75 mg/day) in 87.7% and 94.8% of patients in Cohort-2 and Cohort-3, respectively. Cumulative 3-year incidence of GUSTO moderate/severe bleeding was significantly higher in Cohort-3 than in Cohort-2 (12.1% and 9.0%, P<0.0001). After adjusting 17 demographic factors and 9 management factors potentially related to the bleeding events other than the type of P2Y12receptor blocker, the higher bleeding risk in Cohort-3 relative to Cohort-2 remained significant (hazard ratio (HR): 1.52 95% confidence interval (CI) 1.37–1.68, P<0.0001). Cohort-3 compared with Cohort-2 was not associated with lower adjusted risk for myocardial infarction/ischemic stroke (HR: 0.96, 95% CI: 0.87–1.06, P=0.44).Conclusions:In this historical comparative study, Cohort-3 compared with Cohort-2 was associated with excess bleeding risk, which might be at least partly explained by the difference in P2Y12receptor blockers.
