Background:Previous randomized clinical studies have raised concerns about whether inferior vena cava filter (IVCF) can benefit patients with venous thromboembolism (VTE). The present study therefore investigated whether IVCF are associated with in-hospital mortality in Japan.Methods and Results:This study was based on the Diagnosis Procedure Combination database in the Japanese Registry of All Cardiac and Vascular Datasets (JROAD-DPC). Of 2,368,165 patients included in JROAD-DPC, we identified 28,238 who were hospitalized with VTE between 2012 and 2014. We compared in-hospital mortality rates between patients with or without IVCF using propensity score (PS) matching. PS were estimated using logistic regression models in which IVCF was the dependent variable. The other variables consisted of age, sex, Charlson comorbidity index, anti-thrombotic agents and clinical disease status. Patients were aged 68±16 years, and 59.7% were female. Of 28,238 patients, 6,937 (24.5%) were treated with an IVCF. The overall in-hospital mortality was 4.3%. On PS-matched analysis in-hospital mortality was significantly lower with, than without, IVCF (3.1% vs. 4.4%, P<0.001; OR, 0.65; 95% CI: 0.54–0.79).Conclusions:Having an IVCF was independently associated with lower in-hospital mortality in Japanese patients with VTE. This is in sharp contrast to the benefits of IVCF in other countries. The reasons for this difference require further investigation.

Background:Many treatment options are available for pulmonary arterial hypertension (PAH), but specific recommendations for long-term treatment are unavailable. We compared prognosis in PAH patients receiving goal-oriented, sequential combination therapy evaluated using cardiopulmonary exercise testing (CPX) parameters or conventional empiric therapy.Methods and Results:The Goal-Oriented Therapy Evaluated by Cardiopulmonary Exercise Testing for Pulmonary Arterial Hypertension (GOOD EYE) study was a multicenter, retrospective/prospective study in which a total of 129 patients with newly diagnosed PAH were enrolled (goal-oriented sequential combination therapy, n=42; conventional empiric therapy, n=87). Patients in the goal-oriented therapy group received sequential combination therapy, the efficacy of which was regularly evaluated using CPX parameters. Patients in the conventional empiric therapy group received conventional empiric therapy. The primary endpoint was cardiovascular death. In the goal-oriented therapy group, plasma brain natriuretic peptide, mean pulmonary arterial pressure, pulmonary vascular resistance, and 6-min walk test were significantly improved at 12 months compared with baseline. Survival in the goal-oriented therapy group at 1, 2, and 3 years (97.6%, 95.2%, and 86.0%, respectively) tended to be higher than that in the conventional empiric therapy group (P=0.082).Conclusions:Goal-oriented sequential combination therapy evaluated using CPX parameters may be associated with a favorable prognosis compared with conventional empiric therapy in patients with newly diagnosed PAH.

Background: In heart failure (HF) management, early ambulation is recommended to prevent physical deconditioning. The effects of delayed ambulation on later clinical outcomes and the factors linked to delayed ambulation in hospitalized HF patients, however, remain unestablished. Methods and Results: We retrospectively investigated 101 patients (mean age, 66±17 years) who were hospitalized for acute decompensated HF. During the mean follow-up of 244±15 days after hospital discharge, 34 patients had cardiovascular events leading to death or unplanned readmission. Patients with cardiovascular events had longer median days to acquire ambulation than those without cardiovascular events (11 days, IQR, 8–20 days vs. 7 days, IQR, 5–15 days, P<0.001). The optimal cut-off period until initiation of ambulation to discriminate cardiovascular events was 8 days, indicating that longer days (≥8 days) to acquire ambulation was associated with higher rates of cardiovascular events, even after adjustment of multiple confounders. On multivariate analysis, age >65 years (odds ratio [OR], 2.49; 95% confidence interval [CI]: 1.04–6.09) and increase in blood urea nitrogen (BUN; OR, 1.04; 95% CI: 1.01–1.08) were independent predictors of delayed ambulation. Conclusions: Delayed ambulation is associated with older age and increased BUN in patients with acute HF. Time to ambulation in the recovery phase of acute HF is important, and delayed ambulation may increase the rate of cardiovascular events after hospital discharge.

Background: The outcome of redo transcatheter aortic valve (TAV) implantation (TAVI) is unknown for TAV structural valve degeneration (SVD). This paper reports the initial results of redo TAVI for TAV-SVD in Japanese patients. Methods and Results: Of 630 consecutive patients, 6 (1.0%) underwent redo TAVI for TAV-SVD (689–1,932 days after the first TAVI). The first TAV were 23-mm balloon-expandable valves (BEV, n=5) and a 26-mm self-expandable valve (SEV, n=1). All patients underwent multidetector computed tomography (MDCT) before redo TAVI, which showed first-TAV under-expansion (range, 19.1–21.0 mm) compared with the label size. Two BEV and 4 SEV were successfully implanted as second TAV, without moderate/severe regurgitation or 30-day mortality. One of 2 patients with a BEV-inside-BEV implantation had a high transvalvular mean pressure gradient post-procedurally (34 mmHg) and required surgical valve replacement 248 days after the redo TAVI. This, however, was unnoted in patients with SEV implantation during redo TAVI. Planned coronary artery bypass grafting was concomitantly performed in 1 patient with a small sino-tubular junction and SEV-inside-SEV implantation because of the risk of coronary malperfusion caused by the first TAV leaflets. Five of the 6 patients survived during the follow-up period (range, 285–1,503 days). Conclusions: Redo TAVI for TAV-SVD appears safe and feasible, while specific strategies based on MDCT and device selection seem important for better outcomes.

Background: Early ambulation has been shown to be associated with shorter hospital stay and better clinical outcomes in patients with acute heart failure (HF). Early mobilization program in combination with structured exercise training is recommended, but has yet to be developed and implemented in HF. Methods and Results: We developed a progressive mobilization program for HF patients that classifies the mobilization process into 7 stages based on disease condition and physical function. We retrospectively analyzed 136 patients with acute HF (80±11 years), who were assigned either to the mobilization program (intervention group, n=75) or to usual care (control group, n=61). The program was safely implemented without any adverse events. Hospital stay was significantly reduced in the intervention group compared with the control group (33±25 vs. 51±36 days, P<0.01). The intervention group had higher activities of daily living (ADL) score at discharge evaluated using the Barthel index (64±38 vs. 49±36, P<0.05). The intervention group also had a higher percentage of discharge to home (71% vs. 52%, P<0.05) and a lower rate of HF-related readmission (16% vs. 36%, P<0.05) compared with the control group. Conclusions: The progressive mobilization program for acute HF was feasible and was associated with better ADL and reduced hospital stay, leading to improvement of clinical outcome.

Background: The purpose of the study was to evaluate the impact of nutritional status on 1-year mortality in hospitalized patients with acute decompensated heart failure (ADHF). Methods and Results: We enrolled 457 hospitalized ADHF patients. Previously established objective nutritional indexes (controlling nutritional status [CONUT], prognostic nutritional index [PNI], geriatric nutritional risk index [GNRI], and subjective global assessment [SGA]) were evaluated at hospital admission. Malnutrition was defined as CONUT score ≥5, PNI score <38, GNRI score <92, and SGA scores B and C. The frequencies of malnutrition based on CONUT, PNI, GNRI, and SGA were 31.5%, 21.4%, 44.9%, and 27.8%, respectively. All indexes were related to the occurrence of 1-year mortality on univariate Cox regression analysis (P<0.05). We constructed a reference model using age, body mass index, systolic blood pressure, sodium concentration, and renal function on multivariable Cox regression analysis. Adding SGA to the reference model significantly improved both net reclassification improvement (NRI) and integrated discrimination improvement (0.344, P=0.002; 0.012, P=0.049; respectively). Other indexes (CONUT, PNI, and GNRI scores) significantly improved NRI (0.254, P=0.019; 0.273, P=0.013; 0.306, P=0.006; respectively). Conclusions: Nutritional screening assessed at hospital admission was appropriate for the prediction of 1-year mortality in hospitalized patients with ADHF.

Background: Despite evidence of the effects of alirocumab on the incidence of acute coronary events, its impact on plaque stabilization remains uncertain. The present study will investigate the effect of alirocumab on fibroatheroma in patients who underwent recent percutaneous coronary intervention (PCI). Methods and Results: This phase IV, open-label, randomized, blinded near-infrared spectroscopy plus intravascular ultrasound (NIRS-IVUS) analysis, parallel-group, single-center study will enroll Japanese adults recently hospitalized for PCI with suboptimal low-density lipoprotein cholesterol (LDL-C) control (>70 mg/dL) despite stable statin therapy. Thirty patients will be randomized to receive either alirocumab or standard of care. The alirocumab group will receive alirocumab 75 mg every 2 weeks plus 10 mg rosuvastatin per day. The standard-of-care group will receive 10 mg rosuvastatin per day with dose adjustment to achieve LDL-C <70 mg/dL. Post-treatment NIRS-IVUS will be performed at week 36. The primary endpoint is the change in maximum lipid core burden index in 4-mm pullback compartments (maxLCBI[4 mm]) between baseline and week 36. Secondary endpoints include change in LCBI (lesion), angle of lipid core, plaque burden, and serum lipids and biomarkers related to atherosclerosis and inflammation. Conclusions: The study will clarify the effects of alirocumab on thin-cap fibroatheroma in patients who underwent recent PCI and who have suboptimal LDL-C control with stable statin therapy.

Background: The features of sleep-associated acute heart failure (AHF) patients admitted at midnight or early morning (M/E) are unclear. Methods and Results: Of 1,268 AHF patients screened, 932 were analyzed, and divided into 2 groups by admission time (M/E group, 23:00–06:59, n=399; daytime group, 07:00–22:59, n=533). Those in the M/E group were further divided by the presence of a prodrome: with (n=176; prodrome group) or without (n=223; sudden onset group). The median time from symptom onset to hospitalization was significantly shorter in the M/E group (98 min; range, 65–170 min) than in the daytime group (123 min; range, 68–246 min). The 365-day HF event rate in the M/E group was significantly lower than that of the daytime group. On multivariate logistic regression modeling the M/E group was independently associated with a better outcome than the daytime group (OR, 0.673; 95% CI: 0.500–0.905). In the M/E group, the 365-day HF event rate was significantly lower in the prodrome group than in the sudden onset group. On multivariate logistic regression modeling, inclusion in the prodrome group was independently associated with a better outcome (OR, 0.544; 95% CI: 0.338–0.877). Conclusions: AHF patients admitted during sleeping hours were not sicker than those admitted during the daytime. The absence of a prodrome, however, might be associated with future repeated HF events.

Background: There is a strong demand for remote monitoring systems to gather health data. This study investigated the safety, usefulness, and patient satisfaction in outpatient care using telehealth with real-time electrocardiogram (ECG) monitoring after catheter ablation.Methods and Results: In all, 38 patients who underwent catheter ablation were followed up using telehealth. At the 3- and 6-month follow-up, a self-fitted Duranta ECG monitoring device was sent to the patient’s home before the online consultation. Patients attached the devices themselves, and the doctors viewed the patients by video chat and performed real-time ECG monitoring. The frequency of hospital visits and the ECG monitoring duration were compared with conventional in-person follow-up data (n=102). The completion rate for telehealth follow-up was 32 of 38 patients (84%). The number of hospital visits during the 6 months was significantly lower with telehealth follow-up than with conventional follow-up (median [interquartile range] 1 [1–1] vs. 5 [3–5]; P<0.0001). However, the ECG monitoring duration was approximately 4-fold longer for the telehealth follow-up (median [interquartile range] 89 [64–117] vs. 24 [0.1–24] h; P<0.0001). No major adverse events were observed during the telehealth follow-up. Patient surveys showed high satisfaction with telehealth follow-up due to reduced hospital visits.Conclusions: A combination of telehealth follow-up with real-time ECG monitoring increased the ECG monitoring duration and patient satisfaction without any adverse events.

Background: Post hoc analysis of the PARADIGM-HF trial showed that sacubitril/valsartan (S/V) was more effective than enalapril in lowering HbA1c in patients with heart failure and diabetes.Methods and Results: In the present study, the effect of S/V on glycemic control was retrospectively analyzed in 150 patients (median age 74 years) who were prescribed S/V for the treatment of heart failure and/or hypertension. After a median period of 13 weeks treatment, mean (±SD) HbA1c levels decreased significantly from 6.56±0.68% to 6.49±0.63%. The decrease in HbA1c was evident in patients with (n=111), but not in those without, diabetes. There were no significant changes in renal function after S/V treatment, but systolic blood pressure was significantly reduced from 141±21 to 134±19 mmHg. Ninety patients had N-terminal pro B-type natriuretic peptide (NT-proBNP) tested, and S/V significantly decreased median NT-proBNP concentrations from 1,026 to 618 pg/mL; however, there was no correlation between the degree of decrease in HbA1c and that in NT-proBNP. Multiple regression analysis revealed that being diabetic, rather than having heart failure, was a significant independent variable for a reduction in HbA1c.Conclusions: Treatment with S/V improved glycemic control in patients with heart failure and/or hypertension, especially in those with concomitant diabetes. This favorable effect on glucose metabolism may be mediated by neprilysin inhibition and is desirable in the treatment of heart failure and hypertension in diabetic patients.

Background: The incidence of heart failure (HF) is increasing, and the mortality from HF remains high in an aging society. Cardiac rehabilitation (CR) programs (CRP) increase oxygen uptake (V̇O2) and reduce HF rehospitalization and mortality. Therefore, CR is recommended for every HF patient. However, the number of outpatients undergoing CR remains low, with insufficient attendance at CRP sessions. In this study we evaluated the outcomes of 3 weeks of inpatient CRP (3w In-CRP) for HF patients.Methods and Results: This study enrolled 93 HF patients after acute-phase hospitalization between 2019 and 2022. Patients participated in 30 sessions of 3w In-CRP (30 min aerobic exercise twice daily, 5 days/week). Before and after 3w In-CRP, patients underwent a cardiopulmonary exercise test, and cardiovascular (CV) events (mortality, HF rehospitalization, myocardial infarction, and cerebrovascular disease) after discharge were evaluated. After 3w In-CPR, mean (±SD) peak V̇O2increased from 11.8±3.2 to 13.7±4.1 mL/min/kg (116.5±22.1%). During the follow-up period (357±292 days after discharge), 20 patients were rehospitalized for HF, 1 had a stroke, and 8 died for any reasons. Proportional hazard and Kaplan-Meier analyses demonstrated that CV events were reduced among patients with a 6.1% improvement in peak V̇O2than in patients without any improvement in peak V̇O2.Conclusions: 3w In-CRP for HF patients improved peak V̇O2and reduced CV events in HF patients with a 6.1% improvement in peak V̇O2.

Background: The existence of atypical fast-slow (F/S) atrioventricular (AV) nodal reentrant tachycardias (NRT) using slow pathway (SP) variants connected to the right atrial (RA) inferolateral (inf) free wall (FW) along the tricuspid annulus (TA), has been neither confirmed nor precisely characterized. Methods and Results: We studied 7 patients (mean age, 48±16 years; 5 men) with F/S-AVNRT with long RP intervals and an earliest atrial activation at the RA inf-FW along the TA (inf-F/S-AVNRT). AV reentrant tachycardia was excluded on observation of the transition zone criteria in all 7 patients. Atrial tachycardia was excluded on the observation of a V-A-V activation sequence after the induction or entrainment of the tachycardia from the right ventricle in all. During the tachycardia, low-frequency, fractionated potentials (LP) preceding the local atrial electrogram were recorded near the site of the earliest atrial activation in 6 patients. Observations of conduction delay and block of the LP during ventricular entrainment or ablation of the tachycardia indicated that LP reflect retrograde activation via the inf-SP. Retrograde SP conduction was interrupted at the site of earliest atrial activation in 3 patients, and in the right posterior septum in 4 patients. Conclusions: inf-F/S-AVNRT are distinct supraventricular tachycardia incorporating an SP variant connected to the RA inf-FW along the TA in the retrograde direction, which were eliminated by ablation.

Background: A high resting heart rate is an independent risk factor for mortality and morbidity in patients with cardiovascular diseases. Ivabradine selectively inhibits the funny current (If) and decreases heart rate without affecting cardiac conduction, contractility, or blood pressure. The effect of ivabradine on exercise tolerance in patients with heart failure with reduced ejection fraction (HFrEF) on standard drug therapies remains unclear.Methods and Results: This multicenter interventional trial of patients with HFrEF and a resting heart rate ≥75 beats/min in sinus rhythm treated with standard drug therapies will consist of 2 periods: a 12-week open-label, randomized, parallel-group intervention period (standard drug treatment+ivabradine group and standard drug treatment group) to compare changes in exercise tolerance between the 2 groups; and a 12-week open-label ivabradine treatment period for all patients to evaluate the effect of adding ivabradine on exercise tolerance. The primary endpoint will be the change in peak oxygen uptake (V̇O2) during the cardiopulmonary exercise test from Week 0 (baseline) to Week 12. Secondary endpoints will be time-dependent changes in peak V̇O2from Week 0 to Weeks 12 and 24. Adverse events will also be evaluated.Conclusions: The EXCILE-HF trial will provide meaningful information regarding the effects of ivabradine on exercise tolerance in patients with HFrEF receiving standard drug therapies and suggestions for the initiation of ivabradine treatment.

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: Frailty is an important prognostic factor in patients with cardiovascular diseases (CVD), and patients with CVD have a high rate of concurrent psycho-emotional stress, as well as depressive mood and anxiety symptoms. Despite this, few reports have examined the effects of the efficacy of Phase II cardiac rehabilitation (CR) in frail patients, including improvements in anxiety levels.Methods and Results: In all, 137 patients (mean [±SD] age 65.8±13.0 years; 71% male) who participated in Phase II CR and were assessed after CR completion were included in this study. Patients were evaluated using the Kihon Checklist (KCL) form at the beginning of CR and were divided into the 3 groups according to KCL scores: frail (n=34, 25%), pre-frail (n=40, 29%), and non-frail (n=63, 46%). Physical function and anxiety levels were compared among the 3 groups. The pre-frail and frail groups had significantly higher state anxiety and trait anxiety than the non-frail group (P<0.01). At the end of Phase II CR, all 3 groups showed significant improvements in the 6-min walking distance (P<0.05). State anxiety improved significantly in the non-frail and pre-frail groups, whereas trait anxiety only improved in the non-frail group.Conclusions: Physical function was improved in frail patients who participated in Phase II CR. However, there was no significant improvement in their level of anxiety.

Background: Recent guidelines for acute coronary syndrome (ACS) recommend prehospital administration of aspirin and nitroglycerin for ACS patients. However, there is no clear evidence to support this. We investigated the benefits and harms of prehospital administration of aspirin and nitroglycerin by non-physician healthcare professionals in patients with suspected ACS.Methods and Results: We searched the PubMed database and used the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach to assess the certainty of evidence. Three retrospective studies for aspirin and 1 for nitroglycerin administered in the prehospital setting to patients with acute myocardial infarction were included. Prehospital aspirin administration was associated with significantly lower 30-day and 1-year mortality compared with aspirin administration after arrival at hospital, with odds ratios (OR) of 0.59 (95% confidence interval [CI] 0.35–0.99) and 0.47 (95% CI 0.36–0.62), respectively. Prehospital nitroglycerin administration was also associated with significantly lower 30-day and 1-year mortality compared with no prehospital administration (OR 0.34 [95% CI 0.24–0.50] and 0.38 [95% CI 0.29–0.50], respectively). The certainty of evidence was very low in both systematic reviews.Conclusions: Our systematic reviews suggest that prehospital administration of aspirin and nitroglycerin by non-physician healthcare professionals is beneficial for patients with suspected ACS, although the certainty of evidence is very low. Further investigation is needed to determine the benefit of the prehospital administration of these agents.
