Background: The characteristics and clinical outcomes associated with sustained ventricular tachycardia and fibrillation (VT/VF) in Japanese acute myocardial infarction (AMI) patients remain unknown.Methods and Results: Consecutive AMI patients (n=1,941) transferred to the Hirosaki University Hospital and treated with primary percutaneous coronary intervention (PCI) within 12 h of onset were retrospectively studied. The incidence of VT/VF during hospitalization was 8.3%, and 75% of cases occurred by the end of PCI. Independent predictors associated with VT/VF occurrence by the end of PCI and after PCI, respectively, were identified. Additionally, the differences between patients with VT and VF were examined, which revealed that the characteristics of patients and predictors for VT and VF were clearly different. Additionally, the QRS duration during VT was measured, which demonstrated the possible involvement of Purkinje fibers for VT in the acute phase of AMI. Of the patients with VT/VF, 12% required ECMO support due to refractory VT/VF despite intravenous antiarrhythmic agents such as β-blockers, amiodarone, and nifekalant. Among the patients discharged alive, 1,690 were followed up for a mean of 3.7 years. VT/VF occurrence during hospitalization did not affect the mid-term clinical outcomes even in patients with VT.Conclusions: The results clearly indicated that VT/VF is still a serious complications of AMI. We need to identify patients at high risk of developing VT/VF for careful observation and appropriate intervention.

Background:Because ST-elevation myocardial infarction (STEMI) extensively damages the heart, regenerative therapy with pluripotent stem cells such as multilineage-differentiating stress enduring (Muse) cells is required.Methods and Results:In a first-in-human study, 3 STEMI patients with a left ventricular ejection fraction (LVEF) ≤45% after successful percutaneous coronary intervention received intravenously 1.5×107cells of a human Muse cell-based product, CL2020. The safety and efficacy on LVEF and wall motion score index (WMSI) were evaluated for 12 weeks. No adverse drug reaction was noted. LVEF and WMSI were markedly improved.Conclusions:The first-in-human intravenous administration of CL2020 was safe and markedly improved LV function in STEMI patients.

Background: Although B-type natriuretic peptide (BNP) and N-terminal (NT)-proBNP are commonly used markers of heart failure, a simple conversion formula between these peptides has not yet been developed for clinical use.Methods and Results: A total of 9,394 samples were obtained from Nara Medical University, Jichi Medical University, and Osaka University. We randomly selected 70% for a derivation set to investigate a conversion formula from BNP to NT-proBNP using estimated glomerular filtration rate (eGFR) and body mass index (BMI); the remaining 30% was used as the internal validation set and we used a cohort study from Nara Medical University as an external validation set. Multivariate linear regression analysis revealed a new conversion formula: log NT-proBNP = 1.21 + 1.03 × log BNP − 0.009 × BMI − 0.007 × eGFR (r2=0.900, P<0.0001). The correlation coefficients between the actual and converted values of log NT-proBNP in the internal and external validation sets were 0.942 (P<0.0001) and 0.891 (P<0.0001), respectively. We applied this formula to samples obtained from patients administered with sacubitril/valsartan. After treatment initiation, NT-proBNP levels decreased and actual BNP levels increased. However, the calculated BNP levels decreased roughly parallel to the NT-proBNP levels.Conclusions: This new and simple conversion formula of BNP and NT-proBNP with eGFR and BMI is potentially useful in clinical practice.

Background:The impact of promotional tweets from the official journal account (forCirculation JournalandCirculation Reports) on article viewership has not been thoroughly evaluated.Methods and Results:We retrospectively collected journal viewership data forCirculation JournalandCirculation Reportsfrom March 2021 to August 2021. We compared viewership between articles with (n=15) and without (n=250) tweets. After 1 : 4 propensity score matching (15 tweeted articles and 60 non-tweeted matched controls), journal viewership metrics within 7 days of the tweeting date (and the hypothetical tweeting date), was larger in tweeted articles than non-tweeted articles (median [interquartile range] Abstract page views 89 [60–104] vs. 18 [8–41]).Conclusions:This pilot study suggests a positive relationship between journal-posted promotional tweets and article viewership.

Background: In patients with atrial fibrillation (AF) and severe blood stasis in the left atrial appendage (LAA), dense spontaneous echo contrast (SEC) disturbs the distinct visualization of the LAA interior, thus making thrombus diagnosis inconclusive. We aimed to prospectively assess the efficacy and safety of a protocol for a low-dose isoproterenol (ISP) infusion to reduce SEC to exclude an LAA thrombus.Methods and Results: We enrolled 17 patients with AF and dense SEC (Grade 4 or sludge). ISP was infused with gradually increasing doses of 0.01, 0.02, and 0.03 μg/kg/min at 3-min intervals. After increasing the dose to 0.03 μg/kg/min for 3 min, or when the LAA interior was visible, the infusion was terminated. We reassessed the SEC grade, presence of an LAA thrombus, LAA function, and left ventricular ejection fraction (LVEF) within 1 min of ISP termination. Compared with baseline, ISP significantly increased LAA flow velocity, the LAA emptying fraction, LAA wall velocities, and LVEF (all P<0.01). ISP administration significantly reduced the SEC grade (median) from 4 to 1 (P<0.001). The SEC grade decreased to ≤2 in 15 (88%) patients, and the LAA thrombus was excluded. There were no adverse events.Conclusions: Low-dose ISP infusion may be effective and safe to reduce SEC and exclude an LAA thrombus by improving LAA function and LVEF.

Background: Patients with acute pulmonary embolism (APE) often have negative T waves (Neg T) in precordial leads at presentation, but this is also found in acute coronary syndrome (ACS) caused by left anterior descending coronary artery (LAD) disease. Methods and Results: Differences in Neg T on admission electrocardiograms were studied between 107 patients with APE and 248 patients with ACS caused by LAD disease. All patients had Neg T in leads V1–4 and were admitted within 7 days from symptom onset. The number of leads with Neg T (4.8±1.8 vs. 5.5±1.7, P<0.001) and maximum magnitude of Neg T (3.4±2.0 vs. 4.7±3.3mm, P<0.001) were lower in APE. The frequency of occurrence of Neg T in each of the 12 leads, and the precordial lead with the greatest Neg T (peak Neg T) differed between APE and ACS (all P<0.05, respectively). APE was strongly associated with the presence of Neg T in both leads III and V1 and peak Neg T in leads V1–2. The combination of these 2 findings identified APE with 98% sensitivity, 92% specificity, and 94% predictive accuracy, which represented the highest diagnostic accuracy. Conclusions: Among patients with APE and ACS who have precordial Neg T, the presence of Neg T in leads III and V1 and/or peak Neg T in leads V1–2 simply but accurately differentiates APE from ACS.

Background:It is unclear whether catheter ablation is beneficial for frail elderly patients with atrial fibrillation (AF). This study evaluated the effect of ablation on outcomes in frail elderly patients with AF.Methods and Results:From the Korean National Health Insurance Service database, 194,928 newly diagnosed AF patients were treated with ablation or medical therapy (rhythm or rate control) between 2005 and 2015. Among these patients, the study included 1,818 (ablation; n=119) frail and 1,907 (ablation; n=230) non-frail elderly (≥75 years) patients. Propensity score matching was used to correct for differences between groups. During 28 months (median) follow up, the risk of all-cause death, composite outcome (all-cause death, heart failure admission, stroke/systemic embolism, and sudden cardiac arrest), and each outcome did not change after ablation in frail elderly patients. However, in non-frail elderly patients, ablation was associated with a lower risk of all-cause death (3.5 and 6.2 per 100 person-years; hazard ratio [HR] 0.48; 95% confidence interval [CI] 0.30–0.79; P=0.004), and composite outcome (6.9 and 11.2 per 100 person-years; HR 0.54; 95% CI 0.38–0.75; P<0.001).Conclusions:Ablation may be associated with a lower risk of death and composite outcome in non-frail elderly, but the beneficial effect of ablation was not significant in frail elderly patients with AF. The effect of frailty on the outcome of ablation should be evaluated in further studies.

Background:Acute coronary syndrome (ACS) hospital survivors experience a wide array of late adverse cardiac events, despite considerable advances in the quality of care. We investigated 30-day and 1-year outcomes of ACS hospital survivors using a Japanese nationwide cohort.Methods and Results:We studied 20,042 ACS patients who underwent percutaneous coronary intervention (PCI) in 2017: 10,242 (51%) with ST-elevation myocardial infarction (STEMI), 3,027 (15%) with non-ST-elevation myocardial infarction (NSTEMI), and 6,773 (34%) with unstable angina (UA). The mean (±SD) age was 69.6±12.4 years, 77% of the patients were men, and 20% had a previous history of PCI. The overall 30-day all-cause, cardiac, and non-cardiac mortality rates were 3.0%, 2.4%, and 0.6%, respectively. The overall 1-year incidence of all-cause, cardiac, and non-cardiac death was 7.1%, 4.2%, and 2.8%, respectively. Compared with UA patients, STEMI patients had a higher risk of all fatal events, non-fatal ischemic stroke, and acute heart failure, and NSTEMI patients had a higher risk of heart failure.Conclusions:The results from our ACS hospital survivor PCI database suggest the need to improve care for the acute myocardial infarction population to lessen the burden of 30-day mortality due to ACS, heart failure, and sudden cardiac death, as well as 1-year ischemic stroke and heart failure events.

Background:Recently, identification of independent risk factors for ischemic stroke in Japanese non-valvular atrial fibrillation (NVAF) patients was made by analyzing the 5 major Japanese registries: J-RHYTHM Registry, Fushimi AF Registry, Shinken Database, Keio interhospital Cardiovascular Studies, and the Hokuriku-Plus AF Registry.Methods and Results:The predictive value of the risk scheme in Japanese NVAF patients was assessed. Of 16,918 patients, 12,289 NVAF patients were analyzed (mean follow up, 649±181 days). Hazard ratios (HRs) of each significant, independent risk factor were determined by using adjusted Cox-hazard proportional analysis. Scoring system for ischemic stroke was created by transforming HR logarithmically and was estimated by c-statistic. During the 21,820 person-years follow up, 241 ischemic stroke events occurred. Significant risk factors were: being elderly (aged 75–84 years [E], HR=1.74), extreme elderly (≥85 years [EE], HR=2.41), having hypertension (H, HR=1.60), previous stroke (S, HR=2.75), type of AF (persistent/permanent) (T, HR=1.59), and low body mass index <18.5 kg/m2(L, HR=1.55) after adjusting for oral anticoagulant treatment. The score was assigned as follows: 1 point to H, E, L, and T, and 2 points to EE and S (HELT-E2S2score). The C-statistic, using this score, was 0.681 (95% confidence interval [CI]=0.647–0.714), which was significantly higher than those using CHADS2(0.647; 95% CI=0.614–0.681, P=0.027 for comparison) and CHA2DS2-VASc scores (0.641; 95% CI=0.608–0.673, P=0.008).Conclusions:The HELT-E2S2score may be useful for identifying Japanese NVAF patients at risk of ischemic stroke.

Background:A high level of apolipoprotein B (apoB) is associated with incident coronary artery disease (CAD) when low-density lipoprotein cholesterol (LDL-C) level is discordantly low or concordantly high. However, data on the relationship of apoB with subclinical measure of CAD are limited.Methods and Results:A total of 14,205 men (mean age 41.0 years) who were free of cardiovascular disease at baseline and who underwent a health checkup exam, including measurement of coronary artery calcium (CAC), were studied. Of the study group, 2,773 participants (19.5%) had CAC at baseline, and CAC progression was observed in 2,550 (18.0%). The multivariate-adjusted CAC score ratios (95% confidence interval) comparing discordantly high apoB/low LDL-C and concordantly high apoB/high LDL-C with concordantly low apoB/low LDL-C were 1.51 (0.98–2.32) and 2.70 (2.19–3.33), respectively. The corresponding relative risks for CAC progression were 1.26 (1.02–1.56) and 1.49 (1.34–1.66), respectively. These associations did not change appreciably after adjustment for insulin resistance and subclinical inflammation.Conclusions:Discordant analysis showed that a high apoB level was strongly associated with prevalence and progression of CAC independent of LDL-C in a large cohort of healthy adults. The present study results highlighted the importance of an apoB measure as a potential target for primary prevention of coronary atherosclerosis in healthy adults.

Background: Despite the importance of implementing the concept of social determinants of health (SDOH) in the clinical practice of cardiovascular disease (CVD), the tools available to assess SDOH have not been systematically investigated. We conducted a scoping review for tools to assess SDOH and comprehensively evaluated how these tools could be applied in the field of CVD.Methods and Results: We conducted a systematic literature search of PubMed and Embase databases on July 25, 2023. Studies that evaluated an SDOH screening tool with CVD as an outcome or those that explicitly sampled or included participants based on their having CVD were eligible for inclusion. In addition, studies had to have focused on at least one SDOH domain defined by Healthy People 2030. After screening 1984 articles, 58 articles that evaluated 41 distinct screening tools were selected. Of the 58 articles, 39 (67.2%) targeted populations with CVD, whereas 16 (27.6%) evaluated CVD outcome in non-CVD populations. Three (5.2%) compared SDOH differences between CVD and non-CVD populations. Of 41 screening tools, 24 evaluated multiple SDOH domains and 17 evaluated only 1 domain.Conclusions: Our review revealed recent interest in SDOH in the field of CVD, with many useful screening tools that can evaluate SDOH. Future studies are needed to clarify the importance of the intervention in SDOH regarding CVD.

Background: This study used echocardiography to investigate non-invasive myocardial work (MCW) indices in infants born to mothers with diabetes mellitus (DM) in pregnancy (gestational DM: GDM), including those diagnosed under novel classification criteria and those with pre-existing DM.Methods and Results: This single-centered, retrospective study included 25 infants born to mothers with GDM (termed “infant with GDM”), which was diagnosed by oral glucose tolerance test results during pregnancy or the presence of diabetes before the current pregnancy. We evaluated the relationship between the infant’s MCW, such as global constructive work (GCW), global work index (GWI), global work efficiency (GWE), and global wasted work (GWW), and the mother’s GDM maximal HbA1c during pregnancy. HbA1c level in GDM significantly negatively correlated with GWI* (r=−0.565) and GCW* (r=−0.641). In infants with GDM, GWI and GCW were significantly higher with <6.5% HbA1c than in those with >6.5% HbA1c GDM; however, the specific-layer global longitudinal strain analyses did not show any significant differences between the groups. The pressure-strain loop in infants with >6.5% HbA1c in GDM tended to be smaller than in those infants with <6.5% HbA1c GDM.Conclusions: The hyperglycemic environment of GDM leads to impaired MCW in the infants. MCW is useful for screening for cardiac illnesses among infants with GDM. Appropriate maternal blood glucose management while maintaining HbA1c <6.5% might be beneficial for the cardiac performance of infants with GDM.
