Background:Frailty is prevalent in patients with heart failure (HF) and associated with increased morbidity and mortality. Hence, there has been increased interest in the reversibility of frailty following treatment with medication or surgery. This systematic review aimed to assess the reversibility of frailty in patients with HF before and after surgical interventions aimed at treating the underlying cause of HF. It also aimed to assess the efficacy of cardiac rehabilitation and prehabilitation in reversing or preventing frailty in patients with HF.Methods and Results:Searches of PubMed, MEDLINE and Academic Search Ultimate identified studies with HF patients undergoing interventions to reverse frailty. Titles, abstracts and full texts were screened for eligibility based on the PRISMA guidelines and using predefined inclusion/exclusion criteria in relation to participants, intervention, control, outcome and study design. In total, 14 studies were included: 3 assessed the effect of surgery, 7 assessed the effect of rehabilitation programs, 2 assessed the effect of a prehabilitation program and 2 assessed the effect of program interruptions on HF patients.Conclusions:Overall, it was found that frailty is at least partially reversible and potentially preventable in patients with HF. Interruption of rehabilitation programs resulted in deterioration of the frailty status. Future research should focus on the role of prehabilitation in mitigating frailty prior to surgical intervention.

Background:Outcomes of cryoballoon ablation for persistent atrial fibrillation (AF) are unclear, especially in Japanese patients, so the effectiveness and safety of cryoballoon ablation in clinical practice were retrospectively compared with those of contact force-sensing radiofrequency (CFRF) ablation including the high-power protocol.Methods and Results:Consecutive patients with persistent AF were reviewed, and 253 and 265 patients who underwent cryoballoon and CFRF ablation, respectively, were enrolled. The primary endpoint was atrial arrhythmia recurrence. The secondary endpoints were periprocedural complications and repeat ablation. The rate of additional left atrial (LA) ablation after pulmonary vein isolation (PVI) was similar between groups (68.8% cryoballoon vs. 74.0% CFRF, P=0.19). Freedom from atrial arrhythmia recurrence was comparable between groups over a follow-up of 25.5±12.5 months (72.3% cryoballoon vs. 69.8% CFRF; adjusted hazard ratio (HR) 0.85, 95% confidence interval (CI) 0.59–1.21, P=0.36). Outcomes were similar in the subgroups of PVI alone and PVI plus additional LA ablation. LA posterior wall isolation, absence of defragmentation, and low creatine clearance, but not catheter selection, were associated with the primary endpoint. Periprocedural complications (adjusted HR 0.73, 95% CI 0.34–1.54, P=0.41) and repeat ablation (adjusted HR 1.11, 95% CI 0.71–1.74, P=0.64) were similar for both procedures.Conclusions:Cryoballoon ablation for persistent AF in Japanese clinical practice had acceptable outcomes comparable to those of advanced CFRF ablation.

A myocardial bridge (MB), partially covering the coronary artery, is a congenital anatomical variant usually present in the left anterior descending coronary artery (LAD). MB causes coronary heart disease (CHD) by 2 distinct mechanisms influenced by the anatomical properties of the MB, such as its length, thickness, and location. One is direct MB compression of the LAD at cardiac systole, resulting in delayed arterial relaxation at diastole, reduced blood flow reserve, and decreased blood perfusion. The other is enhancement of coronary atherosclerosis causing stenosis of the LAD proximal to the MB, occurring because of endothelial injury arising from the abnormal hemodynamics provoked by retrograde blood flow up toward the left coronary ostium at cardiac systole. The magnitude of the effect of the 2 distinct mechanisms of the MB on LAD blood flow is prescribed by a common root of the MB-muscle mass volume generated by those properties. Furthermore, the anatomical properties of the MB are closely associated with the choice of treatment and therapeutic outcome in CHD patients having an MB. Thus, the anatomical properties of an MB should be considered in the diagnosis and management of CHD patients with this anomaly. (Circ J 2011; 75: 1559-1566)

Background:The degree of association between mortality and case volume/physician volume is well known for many surgical procedures and medical conditions. However, the link between physician volume and death rate in patients hospitalized for stroke remains unclear. This study analyzed the correlation between in-hospital stroke mortality and physician volume per hospital, considering board certification status.Methods and Results:For this retrospective registry-based cohort study, data were obtained from the Japanese nationwide registry on patients hospitalized for ischemic stroke, intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH) between 2010 and 2016. The number of stroke care physicians and relevant board-certified physicians was also obtained. Odd ratios (ORs) of 30-day in-hospital mortality were estimated after adjusting for institutional and patient differences using generalized mixed logistic regression. From 295,150 (ischemic stroke), 98,657 (ICH), and 36,174 (SAH) patients, 30-day in-hospital mortality rates were 4.4%, 16.0%, and 26.6%, respectively. There was a correlation between case volume and physician volume. A higher number of stroke care physicians was associated with a reduction in 30-day mortality after adjusting for stroke case volume and comorbidities for all stroke types (all P for trend<0.05).Conclusions:An increased number of stroke care physicians was associated with reduced in-hospital mortality for all types of stroke. The volume threshold of board-certified physicians depends on the specialty and stroke type.

Background:Little evidence is available regarding the long-term outcome in elderly patients after deferral of revascularization based on fractional flow reserve (FFR).Methods and Results:From the J-CONFIRM registry (long-term outcomes of Japanese patients with deferral of coronary intervention based on fractional flow reserve in multicenter registry), 1,262 patients were divided into 2 groups according to age: elderly and younger patients (aged ≥75 or <75 years, respectively). The primary endpoint was the cumulative 5-year incidence of target vessel failure (TVF), defined as a composite of cardiac death, target vessel-related myocardial infarction (TVMI), and clinically driven target vessel revascularization (CDTVR). Cumulative 5-year incidence of TVF was not significantly different between elderly and younger patients (14.3% vs. 10.8%, P=0.12). Cardiac death occurred more frequently in elderly patients than younger patients (4.4% vs. 0.8%, P<0.001), whereas TVMI and CDTVR did not differ between groups (1.3% vs. 0.9%, P=0.80; 10.7% vs. 10.1%, P=0.80, respectively). FFR values in lesions with diameter stenosis <50% were significantly higher in elderly patients than in younger patients (0.88±0.07 vs. 0.85±0.07, P=0.01), whereas this relationship was not observed in those with diameter stenosis ≥50%.Conclusions:Elderly patients had no excess risk of ischemic events related to the deferred coronary lesions by FFR, although FFR values in mild coronary artery stenosis were modestly different between elderly and younger patients.

Background:Atrial fibrillation (AF) increases the risk of stroke and death. Oral anticoagulants (OAC) are highly effective in reducing the risk of stroke, and direct oral anticoagulants (DOAC) became available worldwide in 2011.Methods and Results:The Fushimi AF Registry is an on-going prospective survey of AF patients in Fushimi-ku, Kyoto, Japan. The study cohort consisted of 4,489 patients (mean age 73.6 years, 59.6% male, mean CHADS2score 2.03), enrolled in 2011–2017. From 2011 to 2021, antithrombotic therapy has undergone a major transition; the proportion of patients receiving OAC has increased from 53% to 70%, with a steady uptake of DOAC (from 2% to 52%), whereas the proportion of patients receiving antiplatelet agents has decreased from 32% to 14%. Over a median follow-up of 5.1 years, the incidence of stroke/systemic embolism (SE), major bleeding, and all-cause death was 2.2%, 1.9%, and 4.9% per patient-year, respectively. The incidence of stroke/SE (1.6% vs. 2.3%; P<0.01), major bleeding (1.6% vs. 2.0%; P=0.07), and death (4.2% vs. 5.0%; P<0.01) was lower among patients enrolled in 2014–2017 than in 2011–2013, despite comparable baseline characteristics (age 73.2 vs. 73.7 years, CHADS2score 2.03 vs. 2.04, and HAS-BLED score 1.67 vs. 1.77, respectively).Conclusions:Over the past 10 years, there has been a major transition in antithrombotic therapy and a decline in the incidence of adverse events in AF patients.

Background The prevalence and ECG characteristics of idiopathic ventricular arrhythmia originating in the free wall of the right ventricular outflow tract (RVOT) require further clarification, which was the aim of the present study of 110 patients with idiopathic ventricular tachycardia (n=34) or premature ventricular contraction (n=76; OT-VT/PVC) who underwent successful catheter ablation at the RVOT. Methods and Results Ten OT-VT/PVCs (9%) were ablated successfully at the free wall (FW-VT/PVC); the remaining 100 (91%) were ablated at the RVOT septum (Sep-VT/PVC). R wave amplitudes in the inferior leads were significantly smaller in FW-VT/PVC than in Sep-VT/PVC (p<0.01). An RR' pattern in the inferior leads was observed significantly more often in FW-VT/PVC than in Sep-VT/PVC (p<0.001). QS-wave amplitude in each of leads V1 to V3 was significantly deeper in FW-VT/PVC than in Sep-VT/PVC (p<0.001). ECG criteria requiring an RR' pattern in all inferior leads as well as an S-wave amplitude of at least 3.0 mV in lead V2 differentiated FW-VT/PVC from Sep-VT/PVC with high sensitivity, specificity, and predictive accuracy. Conclusions Although FW-VT/PVC has a relatively low prevalence, it has several distinctive ECG characteristics and detailed ECG analysis can differentiate it from Sep-VT/PVC.

Background: The ophthalmic artery Doppler waveform (OADW) is thought to correlate with severity of systemic atherosclerosis. The goal of the present study was to evaluate risk of cardiovascular disease (CVD) in newborns small for gestational age (SGA) and appropriate for gestational age (AGA). Methods and Results: A total of 15 SGA and 26 AGA newborns were enrolled in the study. OADW was compared between SGA and AGA groups. The median Doppler maximums of both eyes in the SGA group were significantly smaller than in the AGA group (maximum average velocity (max A) 6.4cm/s vs. 8.3cm/s, P=0.028; maximum end diastolic velocity (max D) 2.2cm/s vs. 3.4cm/s, P=0.003). The maximums of both eyes for the maximum resistivity index (max RI) and maximum pulsatility index (max PI) in the SGA group were significantly greater than in the AGA group (RI, 0.88 vs. 0.82, P=0.005; PI, 2.23 vs. 1.72, P=0.002). When a multiple linear regression analysis of the SGA group with a stepwise procedure was applied to positive variables from 2-sided comparisons, significant correlations were noted for max A and max PI (max A: R2=0.495, β=0.541, P=0.034; max PI: β=-3.318, P=0.012). Conclusions: OADW in SGA newborns may be related to future risk of CVD, which is undetectable in infancy, and can provide information to estimate future cardiovascular health.  (Circ J 2012; 76: 2009–2014)

Background:TY-0201 (TY) is a transdermal formulation of bisoprolol that is the free base of bisoprolol fumarate (BO), a drug widely used to treat chronic heart failure (CHF). The objectives of this phase II study were to evaluate the efficacy and safety of TY when switching from oral BO to TY in patients with CHF whose drug therapy was optimized, and to determine the dose conversion rate of BO to TY.Methods and Results:The efficacy and safety of once daily TY patch use for 16 weeks was investigated in 40 patients with CHF who were stabilized with an optimized drug treatment, including BO, after switching from BO to TY at the dose conversion rate of 5:8. The pre-switch left ventricular ejection fraction was 50.13±11.09% (mean±SD). The post-switch value was 50.87±10.79% after 16 weeks, which was not significantly different, with similar results for other efficacy and safety parameters. The 16-week study was continued for all patients without changing doses after switching to TY. No cardiovascular deaths, hospitalizations for worsening HF, or significant safety concerns were observed.Conclusions:Efficacy was maintained without significant safety concerns in patients with CHF who were stabilized with BO treatment after switching to TY, suggesting the appropriateness of the dose conversion rate.

Background:This study aimed to investigate the effect of periodontal disease (PD) on the outcomes of patients with coronary artery disease (CAD) treated with percutaneous coronary intervention (PCI).Methods and Results:The study included 77 consecutive non-smoking patients with de novo coronary lesions treated with a drug-eluting stent (DES). Periodontal measurements, including the community periodontal index (CPI), were performed by independent periodontists. A CPI score of ≥3 was used to define PD. The occurrence of major adverse cardiac events (MACEs), which were defined as a composite of cardiovascular death, non-fatal myocardial infarction, target lesion revascularization, or non-target lesion revascularization, was compared between patients with and without PD. Of the 77 patients, 49 (63.6%) exhibited a CPI score of 3 or 4 and were assigned to the PD group. The remaining 28 patients (36.4%) were assigned to the non-PD group. Baseline clinical characteristics and angiographic findings were comparable between the 2 groups. MACEs occurred in 13 (26.5%) of the PD patients and 2 (7.1%) of the non-PD patients. Kaplan-Meier analysis showed a significantly lower MACE-free survival rate in the PD group than for the non-PD group (P=0.034).Conclusions:PD at baseline was associated with an increased risk of MACEs in CAD patients who were treated with a DES for de novocoronary lesions.

Background:Aiming to establish an effective tool in new cardiac rehabilitation programs, we investigated the use of a lumbar-type hybrid assistive limb (HAL) in patients with heart failure (HF) who had difficulty in walking at the usual speed of healthy subjects (≈80 m/min).Methods and Results:We randomly assigned 28 HF patients (age, 73.1±13.8 years) to perform a sit-to-stand exercise with or without HAL. The sit-to-stand exercise was repeated as many times as possible as cardiac rehabilitation therapy over a period of 6–10 days. We measured 5 parameters before and after the completion of cardiac rehabilitation: B-type natriuretic peptide, Short Physical Performance Battery (SPPB), 6-min walking distance (6MWD), 30-s chair-stand test (CS-30), and isometric knee extensor muscle strength. The SPPB and 6MWD were significantly improved, and the CS-30 score was somewhat improved, after the exercise therapy in both the HAL and non-HAL groups. The knee extensor muscle strength improved significantly in the HAL group (0.29±0.11 to 0.35±0.11 kgf/kg, P<0.01), but showed no change in the non-HAL group (0.35±0.11 to 0.35±0.13 kgf/kg, P=0.40).Conclusions:The improved knee extensor muscle strength in the HAL group suggests that the lumbar-type HAL may be an effective tool for cardiac rehabilitation in HF patients with frailty, which is a predictor of poor prognosis in HF.
