Poor implementation and variable quality of cardiac rehabilitation (CR) for coronary heart disease (CHD) have been a global concern. This nationwide study aimed to clarify the implementation of and ...participation in CR among CHD patients and associated factors in Japan. We conducted a retrospective cohort study using data extracted from the National Database of Health Insurance Claims and Specific Health Checkups of Japan. Patients who underwent percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in 2017-2018 were included. Aspects of CR were assessed in terms of (1) participation in exercise-based CR, (2) pharmacological education, and (3) nutritional education. Of 87,829 eligible patients, 32% had participated in exercise-based CR, with a mean program length of 40 ± 71 days. CABG was associated with higher CR participation compared to PCI (OR 10.2, 95% CI 9.6-10.8). Patients living in the Kyushu region were more likely to participate in CR (OR 2.59, 95% CI 2.39-2.81). Among patients who participated in CR, 92% received pharmacological education, whereas only 67% received nutritional education. In Japan, the implementation of CR for CHD is insufficient and involved varying personal, therapeutic, and geographical factors. CR implementation needs to be promoted in the future.
Background: Polypharmacy was reported to be associated with major bleeding in various populations. However, there are no data on polypharmacy and its association with bleeding in patients undergoing ...percutaneous coronary intervention (PCI).Methods and Results: Among 12,291 patients in the CREDO-Kyoto PCI Registry Cohort-3, we evaluated the number of medications at discharge and compared major bleeding, defined as Bleeding Academic Research Consortium Type 3 or 5 bleeding, across tertiles (T1–3) of the number of medications. The median number of medications was 6, and 88.0% of patients were on ≥5 medications. The cumulative 5-year incidence of major bleeding increased incrementally with increasing number of medications (T1 ≤5 medications 12.5%, T2 6–7 16.5%, and T3 ≥8 20.4%; log-rank P<0.001). After adjusting for confounders, the risks for major bleeding of T2 (hazard ratio HR 1.21; 95% confidence interval CI 1.08–1.36; P=0.001) and T3 (HR 1.27; 95% CI 1.12–1.45; P<0.001) relative to T1 remained significant. The adjusted risks of T2 and T3 relative to T1 were not significant for a composite of myocardial infarction or ischemic stroke (HR 0.95 95% CI 0.83–1.09; P=0.47 and HR 1.06 95% CI 0.91–1.23; P=0.48, respectively).Conclusions: In a real-world population of patients undergoing PCI, approximately 90% were on ≥5 medications. Increasing number of medications was associated with a higher adjusted risk for major bleeding, but not ischemic events.
There is little information on the effect of contrast-induced nephropathy (CIN) on long-term mortality after percutaneous coronary intervention in patients with or without chronic kidney disease ...(CKD). Of 4,371 patients who had paired serum creatinine (SCr) measurements before and after percutaneous coronary intervention and were discharged alive in the Coronary REvascularization Demonstrating Outcome Study in Kyoto registry, the incidence of CIN (an increase in SCr of ≥0.5 mg/dl from the baseline) was 5% in our study cohort. The rate of CIN in patients with CKD was 11%, although it was 2% without CKD (p <0.0001). During a median follow-up of 42.3 months after discharge, 374 patients (8.6%) died. After adjustment for prespecified confounders, CIN was significantly correlated with long-term mortality in the entire cohort (hazard ratio HR 2.26, 95% confidence interval CI 1.62 to 2.29, p <0.0001) and in patients with CKD (HR 2.62, 95% CI 1.91 to 3.57, p <0.0001) but not in patients without CKD (HR 1.23, 95% CI 0.47 to 2.62, p = 0.6). Sensitivity analyses confirmed these results using the criteria defined as elevations of the SCr by ≥25% and 0.3 mg/dl from the baseline, respectively. In conclusion, CIN was significantly correlated with long-term mortality in patients with CKD but not in those without CKD.
The high controlling nutritional status (CONUT) score that represents poor nutritional status has been acknowledged to have prognostic implications in chronic heart failure. We aimed to investigate ...its role in acute decompensated heart failure (ADHF). Using the data from an multicenter registry that enrolled 4056 consecutive patients hospitalized for ADHF in Japan between 2014 and 2016, we analyzed 2466 patients in whom data on the components of the CONUT score at hospital presentation were available. The decrease of lymphocyte count and total cholesterol was assigned with 0, 1, 2, and 3 points and the decrease of albumin was assigned with 0, 2, 4, and 6 points according to the severity. We defined low CONUT score as 0-4 (N = 1568) and high CONUT score as 5-9 (N = 898). The patients in the high CONUT score group were older and more likely to have a smaller body mass index than those in the low CONUT score group. The high CONUT score group was associated with higher rate of death and infection during the index hospitalization compared to the low CONUT score group (9.0% versus 4.4%, and 21.9% versus 12.7%, respectively). After adjusting for confounders, the excess risk of high relative to low CONUT score for mortality and infection was significant (OR: 1.61, 95%CI: 1.05-2.44, and OR: 1.66, 95%CI: 1.30-2.12, respectively). The effect was incremental according to the score. High CONUT score was associated with higher risk for in-hospital mortality and infection in an incremental manner in patients hospitalized for ADHF.
Background: There is a scarcity of reports on the clinical characteristics and management practice in contemporary all-comer patients with acute decompensated heart failure (ADHF). Methods and ...Results: The Kyoto Congestive Heart Failure (KCHF) registry is a prospective observational cohort study enrolling 4,056 consecutive patients who had hospital admission due to ADHF without any exclusion criteria between October 2014 and March 2016 in the 19 participating hospitals in Japan. Baseline characteristics, clinical presentations, management, and in-hospital outcomes were compared between heart failure (HF) with reduced left ventricular ejection fraction (LVEF; HFrEF, LVEF <40%), HF with mid-range LVEF (HFmrEF, LVEF 40–49%), and HF with preserved LVEF (HFpEF, LVEF ≥50%). Of the 4,041 patients with documented LVEF, 1,744 (43%) had HFpEF; 746 (19%), HFmrEF; and 1,551 (38%), HFrEF. The median age was 80 years (IQR, 72–86 years) in the entire population, and was higher with increasing LVEF (P<0.001). The in-hospital mortality rate was higher in the HFrEF than in the HFmrEF and HFpEF groups (9.2%, 4.8%, and 5.1%, respectively, P<0.001). Conclusions: This registry elucidated the clinical features and clinically relevant in-hospital outcomes in contemporary consecutive patients with ADHF in real-world clinical practice in Japan. When classified by LVEF, significant differences in characteristics and in-hospital outcomes existed between patients with HFrEF, HFmrEF, and HFpEF.
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.
People with fast eating habits have been reported to have an increased risk of diabetes and obesity. To explore whether the speed of eating a test meal (tomato, broccoli, fried fish, and boiled white ...rice) influences postprandial blood glucose, insulin, triglyceride, and free fatty acid levels, 18 young, healthy women consumed a 671 kcal breakfast at fast speed (10 min) and slow speed (20 min) with vegetables first and slow speed (20 min) with carbohydrate first on three separate days. This study was conducted using a within-participants cross-over design in which all participants consumed identical meals of three different eating speeds and food orders. Significant ameliorations of both fast and slow eating with vegetables first regimen on postprandial blood glucose and insulin levels at 30 and 60 min were observed compared with those of slow eating with carbohydrates first. In addition, the standard deviation, large amplitude of excursion, and incremental area under the curve for blood glucose and insulin in both fast and slow eating with vegetables first were all significantly lower than those of slow eating with carbohydrate first. Interestingly, there was no significant difference between fast and slow eating on postprandial blood glucose and insulin levels as long as vegetables were consumed first, although postprandial blood glucose at 30 min was significantly lower in slow eating with vegetables first than that of fast eating with the same food order. These results suggest that food order with vegetables first and carbohydrate last ameliorates postprandial blood glucose and insulin concentrations even if the meal was consumed at fast speed.
Background: Hyperpolypharmacy is associated with adverse outcomes in older adults, but because literature on its association with cardiovascular (CV) outcomes after acute decompensated heart failure ...(ADHF) is sparse, we investigated the relationships among hyperpolypharmacy, medication class, and death in patients with HF.Methods and Results: We evaluated the total number of medications prescribed to 884 patients at discharge following ADHF. Patients were categorized into nonpolypharmacy (<5 medications), polypharmacy (5–9 medications), and hyperpolypharmacy (≥10 medications) groups. We examined the relationship of polypharmacy status with the 2-year mortality rate. The proportion of patients taking ≥5 medications was 91.3% (polypharmacy, 55.3%; hyperpolypharmacy, 36.0%). Patients in the hyperpolypharmacy group showed worse outcomes than patients in the other 2 groups (P=0.002). After multivariable adjustment, the total number of medications was significantly associated with an increased risk of death (hazard ratio HR per additional increase in the number of medications, 1.05; 95% confidence interval CI, 1.01–1.10; P=0.027). Although the number of non-CV medications was significantly associated with death (HR, 1.07; 95% CI, 1.02–1.13; P=0.01), the number of CV medications was not (HR, 1.01; 95% CI, 0.92–1.10; P=0.95).Conclusions: Hyperpolypharmacy due to non-CV medications was associated with an elevated risk of death in patients after ADHF, suggesting the importance of a regular review of the prescribed drugs including non-CV medications.
