Background:This study aimed to assess the relationship between hospital-acquired functional decline and the risk of mid-term all-cause death in older patients undergoing transcatheter aortic valve implantation (TAVI).Methods and Results:In total, 463 patients (mean age 85 years, interquartile range [IQR]: 82, 88) undergoing elective TAVI at Sakakibara Heart Institute between 2010 and 2018, who were followed up for 3 years, were enrolled in the study. Hospital-acquired functional decline after TAVI, which was defined by at least a 1-point decrease on the Short Physical Performance Battery before discharge compared to the preoperative score, was assessed. A total of 113 patients (24.4%) showed hospital-acquired functional decline after TAVI, and 50 (11.3%) patients died over a mean follow-up period of 1.9±0.8 years. Kaplan-Meier survival curves indicated that hospital-acquired functional decline was significantly associated with all-cause mortality (log-rank test, P=0.001). On multivariate Cox regression analysis, hospital-acquired functional decline was associated with a higher risk of all-cause mortality (OR 2.108, 95% CI 1.119–3.968, P=0.021) independent of sex, body mass index, advanced chronic kidney disease, and preoperative frailty, as assessed by the modified essential frail toolkit.Conclusions:Hospital-acquired functional decline is associated with mid-term all-cause mortality in older patients following TAVI. Trajectory of functional status is a vital sign, and it is useful for risk stratification in older patients following TAVI.

Background: Angiotensin-converting enzyme 2 (ACE2) has been implicated in human heart failure, but the mechanism remains elusive. We hypothesized that ACE2 deficiency would exacerbate angiotensin (Ang) II-mediated myocardial injury. Methods and Results: 10-week-old ACE2 knockout (ACE2KO) and wild-type mice received by mini-osmotic pump either AngII (1.5mg·kg–1·day–1) or saline for 2 weeks. ACE2 deficiency triggered greater increases in the expression of connective tissue growth factor (CTGF), fractalkine (FKN) and phosphorylated ERK1/2 in AngII-treated ACE2KO hearts. These changes were associated with greater activation of matrix metalloproteinase (MMP) 2, MMP9 and MT1-MMP and exacerbation of myocardial injury and dysfunction. In cultured cardiofibroblasts, exposure to AngII (100nmol/L) for 30min resulted in marked increases in superoxide production and expression of CTGF, FKN and phosphorylated ERK1/2, which were strikingly prevented by recombinant human ACE2 (rhACE2; 1mg/ml) and the CTGF-neutralizing antibody (5μg/ml), but were aggravated by ACE2 inhibitor DX600 (0.5μmol/L). These protective effects of rhACE2 were eradicated by the Ang-(1–7) antagonist A779 (1μmol/L). More intriguingly, rhACE2 treatment significantly abolished AngII-mediated increases in MMP2, MMP9 and MT1-MMP in cardiofibroblasts. Conclusions: Loss of ACE2 exacerbates AngII-mediated inflammation, myocardial injury and dysfunction in ACE2-deficient hearts via activation of the CTGF-FKN-ERK and MMP signaling. ACE2 gene may represent a potential candidate to prevent and treat myocardial injury and heart diseases.  (Circ J 2013; 77: 2997–3006)

Background:This study is the first to evaluate the short-term efficacy and long-term safety of AZD0585, a mixture of omega-3 free fatty acids, in Japanese patients with dyslipidemia.Methods and Results:In this randomized double-blind placebo-controlled Phase III study, 383 patients were randomized to 2 g AZD0585, 4 g AZD0585, or placebo once daily for 52 weeks. Eligible patients had low-density lipoprotein cholesterol (LDL-C) levels controlled regardless of statin use, and triglyceride levels between 150 and 499 mg/dL. The least-squares (LS) mean percentage changes in triglyceride concentrations from baseline to the 12-week endpoint (mean of measurements at Weeks 10 and 12) in the 2 and 4 g AZD0585 and placebo groups were −15.57%, −21.75%, and 11.15% respectively (P<0.0001 for both AZD0585 doses vs. placebo). No clinically significant changes from baseline to the 12-week endpoint in total cholesterol, LDL-C, and LDL-C/apolipoprotein (Apo) B were found with AZD0585. High-density lipoprotein cholesterol (HDL-C) was slightly increased and very low-density lipoprotein cholesterol, non-HDL-C, ApoC-II, and ApoC-III were decreased with AZD0585 compared with placebo at the 12-week endpoint. Lipid profiles up to Week 52 were consistent with those up to the 12-week endpoint. No clinically important safety concerns were raised.Conclusions:AZD0585 significantly decreased serum triglyceride levels compared with placebo at the 12-week endpoint and was generally safe and well tolerated in Japanese patients with dyslipidemia.

Background: This retrospective cohort study evaluated whether long term outcome of atrial resynchronisation therapy using bi-atrial pacing (BiaP) to treat atrial fibrillation (AF) was effective in patients deemed unfit for left atrial (LA) ablation procedures. Methods and Results: The patient population comprised 2 groups: those deemed suitable for left LA ablation (n=14) and those who were not (n=17). Both groups underwent BiaP and outcomes were evaluated by comparing symptoms, AF duration, admissions and antiarrhythmic drugs (AAD) for an equal period of time pre and post implantation. Median follow-up was 24 months (range 8-66 months) for the unsuitable group and 31 months (range 7-84 months) for the suitable group. Efficacy in reduction of both AF and symptoms was similar (P=0.44) in both groups (unsuitable group: 13/17; suitable group: 8/14). There was significant improvement in median AF episodes/week pre and post BiaP in both groups (unsuitable group AF reduction: 5 days/week, P=0.001; suitable group AF reduction: 4.9 days/week, P=0.03); the improvement was similar in both groups (P=0.33). There was a significant reduction in the median number of admissions for AF in both groups (unsuitable group: P=0.003; suitable group: P=0.01) and this reduction was also similar (P=0.70). The median number of AAD was also reduced to a similar degree (P=0.83) in both groups (suitable group: P=0.004; unsuitable group: P=0.001). Conclusions: Atrial resynchronisation therapy is effective in the long term management of drug-resistant AF in patients unsuitable for LA ablation, leading to significant reductions in symptoms, AF duration, admissions and AAD.

Angiotensin-converting enzyme 2 (ACE2), a first homolog of ACE, regulates the renin-angiotensin system by counterbalancing ACE activity. Accumulating evidence in recent years has demonstrated a physiological and pathological role of ACE2 in the cardiovascular, renal and respiratory systems. For instance, in the acute respiratory distress syndrome (ARDS), ACE, AngII, and AT1R promote the disease pathogenesis, whereas ACE2 and the AT2R protect from ARDS. Importantly, ACE2 has been identified as a key SARS-coronavirus receptor and plays a protective role in SARS pathogenesis. Furthermore, the recent explosion of research into the ACE2 homolog, collectrin, has revealed a new physiological function of ACE2 as an amino acid transporter, which explains the pathogenic role of gene mutations in Hartnup disorder. This review summarizes and discusses the recently unveiled roles for ACE2 in disease pathogenesis.

Background: Acute efficacy and long-term prognostic differences between ST-elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (primary PCI) and those treated with pre-intervention thrombolysis combined with back-up of facilitated PCI has not been evaluated in Japanese patients. The purpose of the present study was therefore to evaluate the differences between treatment with primary PCI (primary-PCI group) and pre-treatment with tissue-type plasminogen activator (t-PA) combined with back-up of facilitated PCI (prior-t-PA group). Methods and Results: One hundred and one patients with STEMI were randomly assigned to 2 groups. Patients in the prior-t-PA group were then divided into 2 further groups, the facilitated-PCI and prior-t-PA alone groups. The patency rate at initial angiography, left ventricular ejection fraction (LVEF) at 6 months, and the major adverse cardiac event (MACE)-free rate at 5 years were then compared between the groups. The patency rate and LVEF in the prior-t-PA group was significantly higher than in the primary-PCI group (69% vs 17% respectively, P<0.001; 61.6±9.5% vs 55.0±11.6%, respectively; P=0.01). The MACE-free rate in the prior-t-PA group, however, was lower than in the primary-PCI group (58.7% vs 80.9%; P=0.03). The MACE-free rate in the facilitated-PCI group was equal to that in the primary-PCI group (73.7% vs 80.9%; P=0.39), whereas the MACE-free rate in the prior-t-PA-alone group was significantly lower than in the primary-PCI group (48.1% vs 80.9%; P=0.01). Conclusions: Primary PCI is superior to pre-intervention thrombolysis for long-term prognosis. Moreover, facilitated PCI may be as effective as primary PCI in patients with STEMI.

Background:There is little evidence regarding the effect of outpatient cardiac rehabilitation (CR) on exercise capacity or the long-term prognosis in patients after coronary artery bypass graft surgery (CABG). This study aimed to determine whether participation in outpatient CR improves exercise capacity and long-term prognosis in post-CABG Japanese patients in a multicenter cohort.Methods and Results:We enrolled 346 post-CABG patients who underwent cardiopulmonary exercise testing during early (2–3 weeks) and late (3–6 months) time points after surgery. They formed the Active (n=240) and Non-Active (n=106) CR participation groups and were followed for 3.5 years. Primary endpoint was a major adverse cardiac event (MACE): all-cause death or rehospitalization for acute myocardial infarction/unstable angina/worsening heart failure. Peak oxygen uptake at 3–5 months from baseline was significantly more increased in Active than in Non-Active patients (+26±24% vs. +19±20%, respectively; P<0.05), and the MACE rate was significantly lower in Active than Non-Active patients (3.4% vs. 10.5%, respectively; P=0.02). Multivariate Cox proportional hazard analysis showed that participation in outpatient CR was a significant prognostic determinant of MACE (P=0.03).Conclusions:This unique study showed that a multicenter cohort of patients who underwent CABG and actively participated in outpatient CR exhibited greater improvement in exercise capacity and better survival without cardiovascular events than their counterparts who did not participate.

Background: The aim of the present study was to compare the end-tidal O2 pressure (PETO2) to end-tidal CO2 pressure (PETCO2) in cardiac patients during rest and during 2 states of exercise: at anaerobic threshold (AT) and at peak. The purpose was to see which metabolic state, PETO2 or PETCO2, best correlated with exercise limitation. Methods and Results: Thirty-eight patients with left ventricular (LV) ejection fraction <40% underwent cardiopulmonary exercise testing (CPX). PETO2 and PETCO2 were measured during CPX, along with peak O2 uptake (VO2), AT, slope of the increase in ventilation (VE) relative to the increase in CO2 output (VCO2) (VE vs. VCO2 slope), and the ratio of the increase in VO2 to the increase in work rate (ΔVO2/ΔWR). Both PETO2 and PETCO2 measured at AT were best correlated with peakVO2, AT, ΔVO2/ΔWR and VE vs. VCO2 slope. PETO2 at AT correlated with reduced peak VO2 (r=-0.60), reduced AT (r=-0.52), reduced ΔVO2/ΔWR (r=-0.55) and increased VE vs. VCO2 slope (r=0.74). PETCO2 at AT correlated with reduced peak VO2 (r=0.67), reduced AT (r=0.61), reduced ΔVO2/ΔWR (r=0.58) and increased VE vs. VCO2 slope (r=-0.80). Conclusions: PETCO2 and PETO2 at AT correlated with peak VO2, AT and ΔVO2/ΔWR, but best correlated with increased VE vs. VCO2 slope. PETO2 and PETCO2 at AT can be used as a prime index of impaired cardiopulmonary function during exercise in patients with LV failure.

A link between certain infectious microorganisms and an increased risk of atherosclerotic disease has been suggested. By analyzing the data of subjects who had undergone general health-screening tests, a possible association between carotid atherosclerosis and seropositivity of antibody against hepatitis C virus (HCV) has been previously reported. In the present study, a possible link between carotid atherosclerosis and HCV core protein positivity was assessed, because it is postulated to be a better marker of viremia and thus persistent infection. Of the 1992 enrolled subjects, 496 (25%) had carotid artery plaque, and 25 (1.3%) were positive for HCV core protein. Carotid artery plaque was positive in 480/1967 (24%) and 16/25 (64%) of the core protein-negative and core protein-positive subjects, respectively (p<0.0001 by χ2 test). Serum concentrations of transaminases were higher in core protein-positive subjects, but albumin concentrations were not significantly different between the 2 groups. Multivariate logistic regression analysis showed that HCV core protein positivity is an independent predictor of carotid plaque with an odds ratio of 5.61 (95% confidence interval 2.06-15.26, p<0.001). These data further support the possible link between persistent HCV infection and carotid atherosclerosis in the subjects without severe liver dysfunction. (Circ J 2003; 67: 26 - 30)

Background:The safety of discontinuing oral anticoagulant (OAC) after ablation for atrial fibrillation (AF) in Japanese patients has not been clarified.Methods and Results:A study based on the Atrial Fibrillation registry to Follow the long-teRm Outcomes and use of aNTIcoagulants aftER Ablation (AF Frontier Ablation Registry) was conducted. Data were collected from 3,451 consecutive patients (74.1% men; age, 63.3±10.3 years) who had undergone AF ablation at any of 24 cardiovascular centers in Japan between August 2011 and July 2017. During a 20.7-month follow-up period, OAC therapy was discontinued in 1,836 (53.2%) patients; 51 patients (1.5%) suffered a stroke/transient ischemic attack (TIA), 71 (2.1%) suffered major bleeding, and 36 (1.0%) died. Patients in whom OAC therapy was discontinued were significantly younger than those in whom OACs were continued, and their CHA2DS2-VASc scores were significantly lower. The incidences of stroke/TIA, major bleeding, and death were significantly lower among these patients. Upon multivariate adjustment, stroke events were independently associated with relatively high baseline CHA2DS2-VASc scores but not with OAC status.Conclusions:Although the incidences of stroke/TIA, major bleeding, and death were relatively low among patients for whom OAC therapy was discontinued, stroke/TIA occurrence was strongly associated with a high baseline stroke risk rather than with OAC status. Thus, discontinuation of OAC therapy requires careful consideration, especially in patients with a high baseline stroke risk.

Transthyretin cardiac amyloidosis is a progressive and life-threating disease that is significantly underdiagnosed, and the actual number of patients with the disease is presently unknown. Accumulation of wild-type transthyretin-derived amyloid in the heart is a common finding in very elderly patients. Recent clinical trials demonstrated that tafamidis reduced all-cause death and the number of cardiovascular hospitalizations when compared with placebo. The Japanese Ministry of Health, Labour and Welfare approved tafamidis (Vyndaqel®, Pfizer Inc.) for the treatment of cardiomyopathy caused by both wild-type and mutated transthyretin-derived amyloidoses. This scientific statement on transthyretin-derived cardiac amyloidosis summarizes the conditions for reimbursement of the cost of tafamidis therapy, and the institutional and physician requirements for the introduction of tafamidis.

The investment of nearly 2 decades of clinical investigation into cardiac cell therapy has yet to change cardiovascular practice. Recent insights into the mechanism of cardiac regeneration help explain these results and provide important context in which we can develop next-generation therapies. Non-contractile cells such as bone marrow or adult heart derivatives neither engraft long-term nor induce new muscle formation. Correspondingly, these cells offer little functional benefit to infarct patients. In contrast, preclinical data indicate that transplantation of bona fide cardiomyocytes derived from pluripotent stem cells induces direct remuscularization. This new myocardium beats synchronously with the host heart and induces substantial contractile benefits in macaque monkeys, suggesting that regeneration of contractile myocardium is required to fully recover function. Through a review of the preclinical and clinical trials of cardiac cell therapy, distinguishing the primary mechanism of benefit as either contractile or non-contractile helps appreciate the barriers to cardiac repair and establishes a rational path to optimizing therapeutic benefit.

Background:Pulmonary arterial capacitance (PAC) is a determinant of right ventricular afterload and a strong independent predictor of unfavorable outcomes in advanced heart failure (HF) with pulmonary hypertension (PH). We aimed to test the hypothesis that preoperative PAC may affect postoperative clinical outcomes in patients undergoing aortic valve replacement (AVR) for severe aortic valve stenosis (AS), even in the absence of PH.Methods and Results:We studied 116 patients who underwent AVR for severe AS between January 2005 and December 2017. Right heart catheterization was performed for all patients prior to surgery. PAC and pulmonary vascular resistance (PVR) fit well to a hyperbolic relationship (PAC=0.23/PVR, R2=0.73). PAC also showed an inverse relationship with pulmonary capillary wedge pressure (PCWP) (r=−0.15) and mean pulmonary arterial pressure (r=−0.29) and provided a stronger prediction of death or HF admission than PCWP or PVR (area under the ROC curve of 0.74 vs. 0.40 and 0.41, respectively, P=0.002). During a median follow-up of 36 months, PAC (hazard ratio, 0.48; 95% confidence interval, 0.30–0.78; P=0.003) was an independent predictor of death or hospitalization for HF.Conclusions:In these patients undergoing AVR for severe AS, even in the absence of PH, preoperative reduced PAC was independently associated with adverse surgical outcomes. It seems that preoperative PAC has potential as an independent predictor of long-term prognosis after AVR for severe AS.

Background:The average maternal age at delivery, and thus the associated maternal risk are increasing including in women with congenital heart disease (CHD). A comprehensive management approach is therefore required for pregnant women with CHD. The present study aimed to investigate the factors determining peripartum safety in women with CHD.Methods and Results:We retrospectively collected multicenter data for 217 pregnant women with CHD (age at delivery: 31.4±5.6 years; NYHA classifications I and II: 88.9% and 7.4%, respectively). CHD severity was classified according to the American College of Cardiology/American Heart Association guidelines as simple (n=116), moderate complexity (n=69), or great complexity (n=32). Cardiovascular (CV) events (heart failure: n=24, arrhythmia: n=9) occurred in 30 women during the peripartum period. Moderate or great complexity CHD was associated with more CV events during gestation than simple CHD. CV events occurred earlier in women with moderate or great complexity compared with simple CHD. Number of deliveries (multiparity), NYHA functional class, and severity of CHD were predictors of CV events.Conclusions:This study identified not only the severity of CHD according to the ACC/AHA and NYHA classifications, but also the number of deliveries, as important predictive factors of CV events in women with CHD. This information should be made available to women with CHD and medical personnel to promote safe deliveries.

A multicenter, placebo-controlled, randomized, double-blind trial compared the preventive effect of aprindine and digoxin on the recurrence of atrial fibrillation (AF) with placebo, and also compare the effectiveness of these 2 drugs in the prevention of AF. Patients with symptomatic paroxysmal or persistent AF who had converted to sinus rhythm (SR) were randomly assigned aprindine (40 mg/day), digoxin (0.25 mg/day) or placebo and followed up on an outpatient basis every 2 weeks for 6 months. Of the 141 patients from 36 participating centers, 47 were given aprindine, 47 digoxin, and 47 were on placebo. After the 6-month follow-up, the Kaplan-Meier estimates of the percentage of patients remaining free of recurrent symptomatic AF on aprindine, digoxin and placebo were 33.3%, 29.2% and 21.5%, respectively. In patients remaining in SR for 15 days after from the start of follow-up, freedom from recurrence was significantly more prevalent in the aprindine group than in the placebo group (p=0.0414), but there was no significant difference between the digoxin and placebo groups. The rate of adverse events was similar in the 3 groups. In conclusion, neither aprindine nor digoxin had a significant effect on preventing relapse of symptomatic AF; however, recurrence of AF occurred later with aprindine than with placebo or digoxin.

Background:Ventricular septal defect (VSD) after myocardial infarction (MI) is a rare but fatal complication. We report patients’ characteristics and operative outcomes after surgical repair of post-MI VSD using a national database of Japan.Methods and Results:This was a retrospective review of the Japan Adult Cardiovascular Surgery Database (JCVSD) to identify adults (age ≥18 years) who underwent surgical repair of post-MI VSD between 2008 and 2014. The primary outcome was operative death. We identified 1,397 patients (671 male [48%], 74.1±9.3 years old) undergoing surgical repair of post-MI VSD among 288,736 patients undergoing cardiac surgery enrolled in the JCVSD during the same period. Of these, 1,075 (77.0%) were supported preoperatively with an intra-aortic balloon pump. Surgical status was urgent in 391 (28.0%) and emergency/salvage in 731 (52.3%). Concomitant coronary artery bypass grafting was performed in 475 (34.0%). Overall 30-day and operative mortalities were 24.3% and 33.0%, respectively. Operative mortality varied according to surgical status: 15.6% in elective, 30.9% in urgent, and 40.6% in emergency/salvage cases. Multivariable analysis identified advanced age and emergency/salvage status as being strongly associated with increased odds of operative death.Conclusions:Post-MI VSD remains a devastating complication in Japan as well as in the USA and Europe.
