Background:Atrial fibrillation (AF) recurrence remains a tricky problem in patients undergoing ablation. This meta-analysis aimed to summarize the current literature to clarify whether renin-angiotensin system inhibitors (RASIs) prevent AF recurrence after ablation.Methods and Results:Relevant studies were searched on Pubmed and EMBASE through December 2019. Pooled relative risk (RR) of AF recurrence was calculated. Subgroup analyses according to study design, race, and follow-up duration were further performed. A total of 15 studies examining 4,300 patients were included, with 3 randomized controlled trials and 12 cohort studies. Overall analysis showed that RASIs significantly reduced AF recurrence after ablation (RR=0.83; 95% confidence interval (CI) 0.70–0.98, P=0.028; I2=68.9%). Subgroup analysis further indicated that positive results were found in randomized controlled trials (RR=0.51, 95% CI 0.37–0.70, P<0.001; I2=4%), studies conducted in Asia (RR=0.59, 95% CI 0.46–0.76, P<0.001; I2=30.7%), and studies with follow-up duration ≥1 year (RR=0.82, 95% CI 0.70–0.95, P=0.01; I2=59.1%); negative results were found in cohort studies, studies conducted in Europe or the USA, and studies with follow-up duration <1 year.Conclusions:RASIs can potentially prevent AF recurrence after ablation under selected conditions. However, more studies are required to confirm this finding due to the variation in current evidence.

Background:The appropriate duration of prehospital cardiopulmonary resuscitation (CPR)administered by emergency medical service (EMS) providers for patients with out-of-hospital cardiac arrest (OHCA) necessary to achieve 1-month survival with favorable neurological outcome (Cerebral Performance Category 1 or 2, CPC 1–2) is unclear and could differ by age.Methods and Results:We analyzed the records of 35,709 adult OHCA patients with return of spontaneous circulation (ROSC) before hospital arrival in a prospectively recorded Japanese registry between 2011 and 2014. The CPR duration was defined as the time from CPR initiation by EMS providers to prehospital ROSC. The rate of 1-month CPC 1–2 was 21.4% (7,650/35,709). The CPR duration was independently and inversely associated with 1-month CPC 1–2 (adjusted odds ratio, 0.93 per 1-min increment; 95% confidence interval, 0.93–0.94). The CPR duration increased with age (P<0.001). However, the CPR duration beyond which the proportion of OHCA patients with 1-month CPC 1–2 decreased to <1% declined with age: 28 min for patients aged 18–64 years, 25 min for 65–74 years, 23 min for 75–84 years, 20 min for 85–94 years, and 18 min for ≥95 years.Conclusions:In patients who achieved prehospital ROSC after OHCA, the duration of CPR administered by EMS providers necessary to achieve 1-month CPC 1–2 varied by age.

Background:Transcatheter aortic valve replacement (TAVR) has been performed more and more frequently in elderly patients with aortic stenosis. We investigated the association of in-hospital availability of TAVR on outcomes of surgical aortic valve replacement (SAVR) in the era of TAVR.Methods and Results:We utilized data from the Japan Adult Cardiovascular Surgery Database. Between October 2013 and December 2016, 9,330 patients aged ≥80 years underwent isolated SAVR or SAVR with coronary artery bypass grafting in 557 centers in Japan. We assessed the associations of in-hospital TAVR availability with operative mortality and composite complications adjusting for each patient’s characteristics, JapanSCORE predicted the risk scores, and hospital volumes of SAVR using generalized estimation equation methods. Observed operative mortality rates were 3.4% in all centers, 2.0% in TAVR centers and 4.0% in non-TAVR centers. The multivariable analyses showed that TAVR centers had statistically significantly lower operative mortality compared with non-TAVR centers among all patients (odds ratio 0.60, 95% confidence interval 0.41–0.89, P=0.01) and among intermediate/high-risk patients (odds ratio 0.52, 95% confidence interval 0.32–0.85, P<0.01) but not among low-risk patients (odds ratio 0.82, 95% confidence interval 0.44–1.51, P=0.52).Conclusions:In-hospital TAVR availability was associated with better outcomes of SAVR among elderly patients. This association was statistically significant among intermediate/high-risk patients but not significant among low-risk patients.

A young adult patient with untreated sarcoidosis spontaneously developed a left ventricular (LV) aneurysm in the anterolateral free wall. Single-photon emission computed tomography (SPECT) using Gallium-67 clearly demonstrated widespread abnormal uptake, including the LV aneurysm. Thallium-201 SPECT revealed a perfusion defect in the anterolateral wall, and abnormal uptake of technetium-99m pyrophosphate was seen, especially in the borders of the defect lesion.

Background:Differences between resting full-cycle ratio (RFR) and diastolic pressure ratio (dPR) have not been sufficiently discussed. This study aimed to investigate if there is a difference in diagnostic performance between RFR and dPR for the functional lesion assessment and to assess if there are specific characteristics for discordant revascularization decision-makings between RFR and dPR.Methods and Results:A total of 936 intermediate lesions in 776 patients who underwent measurements of fractional flow reserve (FFR), coronary flow reserve (CFR), and the index of microcirculatory resistance (IMR) were retrospectively studied. Physiological indices were measured from anonymized pressure recordings at an independent core laboratory. Both RFR and dPR measures were highly correlated (r=0.997, P<0.001), with equivalent diagnostic performance relative to FFR-based decision-makings measured by using a dichotomous threshold of 0.80 (accuracy, 79.7% vs. 80.1%, respectively, P=0.960). The rate of diagnostic discordance was 4.7% (44/936), with no RFR−/dPR+ lesions observed. An overall significant difference in FFR and CFR values were detected among RFR/dPR-based classifications. The prevalence of positive studies was significantly higher for RFR than dPR (54.3% vs. 49.6%, respectively, P=0.047) when using the cut-off value of 0.89.Conclusions:Both RFR and dPR were highly correlated, but the prevalence of positive studies was significantly different. The revascularization rate may differ significantly according to the resting index used.

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.
