Abstract
The optimal timing for electrical cardioversion (ECV) in acute decompensated heart failure (ADHF) with atrial arrhythmias (AAs) is unknown. Here, we retrospectively evaluated the impact of ECV timing on SR maintenance, hospitalization duration, and cardiac function in patients with ADHF and AAs. Between October 2017 and December 2022, ECV was attempted in 73 patients (62 with atrial fibrillation and 11 with atrial flutter). Patients were classified into two groups based on the median number of days from hospitalization to ECV, as follows: early ECV (within 8 days, n = 38) and delayed ECV (9 days or more, n = 35). The primary endpoint was very short-term and short-term ECV failure (unsuccessful cardioversion and AA recurrence during hospitalization and within one month after ECV). Secondary endpoints included (1) acute ECV success, (2) ECVs attempted, (3) periprocedural complications, (4) transthoracic echocardiographic parameter changes within two months following successful ECV, and (5) hospitalization duration. ECV successfully restored SR in 62 of 73 patients (85%), with 10 (14%) requiring multiple ECV attempts (≥ 3), and periprocedural complications occurring in six (8%). Very short-term and short-term ECV failure occurred without between-group differences (51% vs. 63%, P = 0.87 and 61% vs. 72%, P = 0.43, respectively). Among 37 patients who underwent echocardiography before and after ECV success, the left ventricular ejection fraction (LVEF) significantly increased (38% [31-52] to 51% [39-63], P = 0.008) between admission and follow-up. Additionally, hospital stay length was shorter in the early ECV group than in the delayed ECV group (14 days [12-21] vs. 17 days [15-26], P < 0.001). Hospital stay duration was also correlated with days from admission to ECV (Spearman's ρ = 0.47, P < 0.001). In clinical practice, early ECV was associated with a shortened hospitalization duration and significantly increased LVEF in patients with ADHF and AAs.

Abstract
BACKGROUND Nonobstructive general angioscopy (NOGA) can identify vulnerable plaques in the aortic lumen that serve as potential risk factors for cardiovascular events such as embolism. However, the association between computed tomography (CT) images and vulnerable plaques detected on NOGA remains unknown. METHODS AND RESULTS We investigated 101 patients (67±11 years; women, 13.8%) who underwent NOGA and contrast-enhanced CT before or after 90 days in our hospital. On CT images, the aortic wall thickness, aortic wall area (AWA), and AWA in the vascular area were measured at the thickest point from the 6th to the 12th thoracic vertebral levels. Furthermore, the association between these measurements and the presence or absence of NOGA-derived aortic plaque ruptures (PRs) at the same vertebral level was assessed. NOGA detected aortic PRs in the aortic lumens at 145 (22.1%) of the 656 vertebral levels. The presence of PRs was significantly associated with greater aortic wall thickness (3.3±1.7 mm versus 2.1±1.2 mm), AWA (1.33±0.68 cm2 versus 0.89±0.49 cm2), and AWA in the vascular area (23.2%±9.3% versus 17.2%±7.6%) (P<0.001 for all) on the CT scans compared with the absence of PRs. The frequency of PRs significantly increased as the aortic wall thickness increased. Notably, a few NOGA-derived PRs were detected on CT in near-normal intima. CONCLUSIONS The presence of NOGA-derived PRs was strongly associated with increased aortic wall thickness, AWA, and AWA in the vascular area, measured using CT. NOGA can detect PRs in the intima that appear almost normal on CT scans.

Abstract
OBJECTIVES This study aimed to investigate the current use and impact of pulmonary artery catheters (PACs) in patients with cardiogenic shock (CS) who underwent Impella support. DESIGN This was a prospective multicenter observational study between January 2020 and December 2021 that registered all patients with drug-refractory acute heart failure and in whom the placement of an Impella 2.5, CP, or 5.0 pump was attempted or successful in Japan. SETTING Cardiac ICUs in Japan. PATIENTS Between January 2020 and December 2021, a total of 3112 patients treated with an Impella were prospectively enrolled in the Japan registry for percutaneous ventricular assist device (J-PVAD). Among them, 2063 patients with CS were divided into two groups according to the PAC use. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The primary endpoint was the 30-day mortality, and the secondary endpoints were hemolysis, acute kidney injury, sepsis, major bleeding unrelated to the Impella, and ventricular arrhythmias within 30 days. PACs were used in 1358 patients (65.8%) who underwent an Impella implantation. The use of venoarterial extracorporeal membrane oxygenation (VA-ECMO) was significantly higher in the patients with PACs than in those without. Factors associated with PAC use were the prevalence of hypertension, out-of-hospital cardiac arrest, New York Heart Association classification IV, the lesser prevalence of a heart rate less than 50, and the use of any catecholamine. The primary and secondary endpoints did not significantly differ according to the PAC use. Focusing on the patients with VA-ECMO use, the 30-day mortality and hemolysis were univariately lower in the patients with PACs. CONCLUSIONS The J-PVAD findings indicated that PAC use did not have a significant impact on the short-term outcomes in CS patients undergoing Impella support. Further prospective studies are required to explore the clinical implications of PAC-guided intensive treatment strategies in these patients.

Abstract
Atrial fibrillation (AF) is an independent risk factor for stroke and systemic embolism. Cardiogenic and aortogenic emboli are causes of stroke or systemic embolism. Non-obstructive general angioscopy (NOGA) can be used to diagnose aortic intimal findings, including thrombi and atherosclerotic plaques, but little is known about NOGA-derived aortic intimal findings in patients with AF. This study focused on aortic intimal findings in patients with AF and evaluated the association between AF and aortic thrombi detected using NOGA. We enrolled 283 consecutive patients with coronary artery disease who underwent NOGA of the aorta between January 2017 and August 2022. Aortic intimal findings were screened using NOGA after coronary arteriography. The patients were divided into two groups according to their AF history (AF, n = 50 and non-AF, n = 233). Patients in the AF group were older than those in the non-AF group. Sex, body mass index, and coronary risk factors were not significantly different between the two groups. In the NOGA findings, the presence of intense yellow plaques and ruptured plaques was not significantly different between the two groups. Aortic thrombi were more frequent in the AF group than in the non-AF group (92.0 vs. 71.6%, p < 0.001). Multivariate logistic regression found that AF was independently associated with aortic thrombi (odds ratio 3.87 [95% CI 1.28-11.6], p = 0.016). The presence of aortic thrombi observed using NOGA was associated with AF in patients with coronary artery disease. The roles of aortic thrombi as well as cardiogenic embolism may require clarification.

Abstract
AIMS Sodium-glucose co-transporter 2 (SGLT2) inhibitors have shown potential therapeutic benefits in heart failure (HF). However, data on their real-world usage and benefits in acute decompensated heart failure (ADHF) are limited. METHODS AND RESULTS We conducted a post hoc analysis of real-world data from 1108 patients with ADHF admitted to Nihon University Itabashi Hospital (Tokyo, Japan) between 2018 and 2022. Patients were divided into two groups based on the prescription of SGLT2 inhibitors during hospitalization: an SGLT2 inhibitor group (SGLT2i group) (n = 289) and a non-SGLT2i group (n = 819). The primary endpoints were death and rehospitalization for HF after discharge. The median age was 76 [interquartile range (IQR): 66, 83] years, and 732 patients (66%) were male. Data showed an increasing trend in the prescription of SGLT2 inhibitors since 2021. During a median follow-up period of 366 days (IQR: 116, 614), 458 (41.3%) patients reached the primary endpoint. The Kaplan-Meier analysis showed that the SGLT2i group had a significantly lower rate of composite events than the non-SGLT2i group, both overall (log-rank test, P < 0.001) and in the following left ventricular ejection fraction (LVEF) subgroups: HF with reduced ejection fraction (EF) (n = 413), HF with mildly reduced EF (n = 226), and HF with preserved EF (n = 466) (log-rank test; P = 0.044, P = 0.013, and P = 0.001, respectively). Furthermore, patients starting SGLT2 inhibitors during hospitalization had a significantly lower rate of composite events than those not using SGLT2 inhibitors (log-rank test, P < 0.001). This association was also significant in the LVEF subgroups (P = 0.005, P = 0.032, and P = 0.004, respectively). CONCLUSIONS The prescription and initiation of SGLT2 inhibitors during hospitalization are associated with improved post-discharge outcomes in patients with ADHF, irrespective of LVEF.

Abstract
A cerebral infarction (CI) is a common complication of coronary angiography (CAG); however, repeated CIs in the immediate period after a CAG have not been reported yet. The patient in the present study experienced left upper quadrant blindness immediately after internal thoracic arteriography, and magnetic resonance imaging (MRI) showed a high-intensity area in the right occipital lobe. Despite the administration of antithrombotic therapy, the patient became transiently comatose for 6 hours. MRI showed a new high-intensity area in the left thalamus. A noninvasive assessment should be considered before internal thoracic arteriography to prevent the risk of complications.

Abstract
BACKGROUND This post hoc subanalysis aimed to investigate the impact of polyvascular disease (PolyVD) in patients with acute myocardial infarction (AMI) in the contemporary era of percutaneous coronary intervention (PCI).Methods and Results: The Japan Acute Myocardial Infarction Registry (JAMIR), a multicenter prospective registry, enrolled 3,411 patients with AMI between December 2015 and May 2017. Patients were classified according to complications of a prior stroke and/or peripheral artery disease into an AMI-only group (involvement of 1 vascular bed [1-bed group]; n=2,980), PolyVD with one of the complications (2-bed group; n=383), and PolyVD with both complications (3-bed group; n=48). The primary endpoint was all-cause death. Secondary endpoints were major adverse cardiovascular events (MACE), including cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, and major bleeding. In the 1-, 2-, and 3-bed groups, the cumulative incidence of all-cause death was 6.8%, 17.5%, and 23.7%, respectively (P<0.001); that of MACE was 7.4%, 16.4%, and 33.8% (P<0.001), respectively; and that of major bleeding was 4.8%, 10.0%, and 13.9% (P<0.001), respectively. PolyVD was independently associated with all-cause death (hazard ratio [HR] 2.21; 95% confidence interval [CI], 1.48-3.29), MACE (HR 2.07; 95% CI 1.40-3.07), and major bleeding (HR 1.68; 95% CI 1.04-2.71). CONCLUSIONS PolyVD was significantly associated with worse outcomes, including thrombotic and bleeding events, in the contemporary era of PCI in AMI patients.

Abstract
Objective Sodium-glucose co-transporter-2 inhibitors (SGLT2is), such as dapagliflozin, have a diuretic effect, and their early initiation to treat acute heart failure (AHF) may improve outcomes; however, the significance of the timing of starting dapagliflozin after hospital admission remains unclear. Methods We performed a post hoc analysis of a prospective, observational registry. Participants were divided into the early (E) group and late (L) group using the median time to the initiation of dapagliflozin (6 days) as the cut-off. We evaluated the relationship between the time to the initiation of dapagliflozin after hospital admission and patient characteristics and the length of the hospital stay. Patients Study subjects were 118 patients with AHF admitted between January 2021 and April 2022 who were started on dapagliflozin treatment (10 mg/day). Results Patients were divided into the E group (n=63) and L group (n=55). The HF severity as evaluated by the New York Heart Association class and the N-terminal pro-brain natriuretic peptide level was not significantly different between the groups. The time to the initiation of dapagliflozin and length of hospital stay showed a significant positive correlation (p<0.001, r=0.46). The hospital stay was significantly shorter in group E [median, 16.5 days; interquartile range (IQR): 13-22 days] than in group L (median, 22 days; IQR: 17-27 days; p=0.002). A multivariate logistic regression analysis showed that the early initiation of dapagliflozin was independently associated with a shorter hospital stay, even after multiple adjustments. Conclusion Early initiation of dapagliflozin after hospital admission is associated with a shorter hospital stay, suggesting it is a key factor for shortening hospital stays.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) and acute myocardial infarction (AMI) have common pathological links. This study investigates the prognostic impact of NAFLD assessed as hepatic steatosis (HS) by computed tomography (CT) in AMI patients and explores the mechanistic role of NAFLD in cardiovascular (CV) events using coronary angioscopy (CAS). METHODS We retrospectively examined 342 AMI patients who underwent CT followed by primary percutaneous coronary intervention (PCI) between January 2014 and December 2019. HS was defined as a hepatic to spleen attenuation ratio of <1.0 on CT scans. Major cardiac events (MCE) included cardiac death, non-fatal myocardial infarction, target-vessel revascularization, and target-lesion revascularization. RESULTS HS was identified in 88 patients (26 %). Patients with HS were significantly younger, had a higher body mass index, and higher hemoglobin A1c, triglyceride, and malondialdehyde low-density lipoprotein levels (all p < 0.05). MCE occurred more frequently [27 (30.7 %) vs. 39 (15.4 %), p = 0.001] in the HS group than in the non-HS group. In the multivariate analysis, the presence of HS was an independent predictor of MCE after adjusting for metabolic risk factor and liver function markers. Among the 74 patients who underwent CAS for a median of 15 days after primary PCI, 51 (69 %) had intrastent thrombus, which was strongly associated with the presence of HS [18 (35 %) vs. 1 (4 %), p = 0.005]. CONCLUSIONS AMI patients with NAFLD detected by CT often had CAS-derived intrastent thrombi and were at a high risk for CV events. Therefore, these patients should be carefully monitored.

Abstract
To investigate the impact of the coronavirus disease 2019 (COVID-19) pandemic on myocardial infarctions (MIs), consecutive MI patients were retrospectively reviewed in a multi-center registry. The patient characteristics and 180-day mortality for both ST-segment elevation myocardial infarctions (STEMIs) and non-STEMIs (NSTEMIs) in the after-pandemic period (7 April 2020-6 April 2021) were compared to the pre-pandemic period (7 April 2019-6 April 2020). Inpatients with MIs, STEMIs, and NSTEMIs decreased by 9.5%, 12.5%, and 4.1% in the after-pandemic period. The type of the presenting symptoms (as classified as typical symptoms, atypical symptoms, and out-of-hospital cardiac arrests [OHCAs]) did not differ between the two time periods for both STEMIs and NSTEMIs, while the rate of OHCAs was numerically higher in the after-pandemic period for the STEMIs (12.1% vs. 8.0%, p = 0.30). The symptom-to-admission time (STAT) did not differ between the two time periods for both STEMIs and NSTEMIs, but the door-to-balloon time (DTBT) for STEMIs was significantly longer in the after-pandemic period (83.0 [67.0-100.7] min vs. 70.0 [59.0-88.7] min, p = 0.004). The 180-day mortality did not significantly differ between the two time periods for both STEMIs (15.9% vs. 11.4%, p = 0.14) and NSTEMIs (9.9% vs. 8.0%, p = 0.59). In conclusion, hospitalizations for MIs decreased after the COVID-19 pandemic. Although the DTBTs were significantly longer in the after-pandemic period, the mid-term outcomes for MIs were preserved.

Abstract
Acute pulmonary embolism (PE) is often associated with rapid hemodynamic deterioration or death. Therefore, early therapeutic intervention is important. A 45-year-old man was diagnosed with intermediate-high risk PE, and sequential hybrid therapy consisting of surgical thrombectomy and rivaroxaban intensive therapy was administered. During the course of treatment, echocardiography revealed improvement in pulmonary artery systolic pressure, and thrombus volume analysis by computed tomography revealed a drastic reduction in the size of the thrombus. Sequential hybrid therapy for acute PE not only stabilizes hemodynamics, but may also prevent conversion to chronic thromboembolic pulmonary hypertension by sufficiently reducing the volume of the thrombus.

Abstract
AIMS Acute decompensated heart failure (ADHF) presents with pulmonary congestion, which is caused by an increased pulmonary arterial wedge pressure (PAWP). PAWP is strongly associated with prognosis, but its quantitative evaluation is often difficult. Our prior work demonstrated that a deep learning approach based on chest radiographs can calculate estimated PAWP (ePAWP) in patients with cardiovascular disease. Therefore, the present study aimed to assess the prognostic value of ePAWP and compare it with other indices of haemodynamic congestion. METHODS AND RESULTS We conducted a post hoc analysis of a single-centre, prospective, observational heart failure registry and analysed data from 534 patients admitted for ADHF between January 2018 and December 2019. The deep learning approach was used to calculate ePAWP from chest radiographs at admission and discharge. Patients were divided into three groups based on the ePAWP tertiles at discharge, as follows: first tertile group (ePAWP ≤ 11.2 mm Hg, n = 178), second tertile group (11.2 < ePAWP < 13.5 mm Hg, n = 170), and third tertile group (ePAWP ≥ 13.5 mm Hg, n = 186). The third tertile group had a higher prevalence of atrial fibrillation and lower systolic blood pressure at admission; a lower platelet count and higher total bilirubin at both admission and discharge; and a higher left atrial diameter, peak early diastolic transmitral flow velocity, right ventricular end-diastolic diameter, and maximal inferior vena cava diameter at discharge. During the median follow-up period of 289 days, 223 (41.7%) patients reached the primary endpoint (a composite of all-cause mortality or rehospitalization for heart failure). Kaplan-Meier analysis revealed a significantly higher composite event rate in the third tertile group (log-rank test, P = 0.006). Even when adjusted for clinically relevant factors, a higher ePAWP at discharge and a smaller decrease in ePAWP from admission to discharge were significantly associated with higher event rates [ePAWP at discharge: hazard ratio, 1.10; 95% confidence interval (CI), 1.02-1.19; P = 0.010; and size of ePAWP decrease: hazard ratio, 0.94; 95% CI, 0.89-0.99; P = 0.038]. CONCLUSIONS Our study suggests that ePAWP calculated by a deep learning approach may be useful for identifying and monitoring pulmonary congestion during hospitalization for ADHF.

Abstract
Abstract
Introduction
Recent studies reported that a convolutional neural network (CNN; a deep learning model) can detect elevated pulmonary artery wedge pressure (PAWP) from chest radiographs, the diagnostic images most commonly used for assessing pulmonary congestion in heart failure. However, no method has been published for quantitatively estimating PAWP from such radiographs. We hypothesized that a regression CNN, an alternative type of deep learning, could be a useful tool for quantitatively estimating PAWP from chest radiographs in cardiovascular diseases.
Methods
We retrospectively enrolled 936 patients with cardiovascular diseases who had undergone right heart catheterization (RHC) and chest radiography and estimated PAWP by constructing a regression CNN based on the VGG16 model. We randomly categorized 80% of the data as training data (training group, n=748) and 20% as test data (test group, n=188). Moreover, we tuned the learning rate–one of the model parameters–by 5-hold cross-validation of the training group. Correlations between PAWP measured by RHC (ground truth [GT] PAWP) and PAWP derived from the regression CNN (estimated PAWP) were tested. To visualize how the regression CNN assessed the images, we created a regression activation map (RAM), a visualization technique for regression CNN.

Estimated PAWP correlated significantly with GT PAWP in both the training (r=0.76, P<0.001) and test group (r=0.62, P<0.001). Bland-Altman plots found a mean (SEM) difference between GT and estimated PAWP of −0.23 (0.16) mm Hg in the training and −0.05 (0.41) mm Hg in the test group. The RAM showed that our regression CNN model estimated high PAWP by focusing on the cardiomegaly and pulmonary congestion. In the test group, the area under the curve (AUC) for detecting elevated PAWP (≥18 mm Hg) produced by the regression CNN model was similar to the AUC of an experienced cardiologist (0.86 vs 0.83, respectively; P=0.24).
Conclusion
This proof-of-concept study shows that regression CNN can quantitatively estimate PAWP from standard chest radiographs in cardiovascular diseases.

Abstract
Stabilization of aortic vulnerable plaques has not been fully elucidated. Non-obstructive general angioscopy (NOGA) is a novel method for the detailed evaluation of atheromatous plaques in the aortic intimal wall. A 57-year-old man presenting with acute myocardial infarction underwent percutaneous coronary intervention (PCI). NOGA was performed for the evaluation of aortic atherosclerosis, and vulnerable puff-chandelier plaques in the aortic arch were identified. After a strictly controlled low-density lipoprotein cholesterol lowering therapy with a strong statin for 8 months after the primary PCI, NOGA revealed stabilized aortic plaques in the same lesions. Therefore, NOGA may be helpful in evaluating the effects of lipid-lowering therapy on aortic plaque stabilization.

Abstract
OBJECTIVE Rivaroxaban is commonly prescribed to prevent venous thromboembolism (VTE). Although lower than standard dosages (under-dosing) may be administered in the real-world setting, data on subsequent clinical outcomes in Japanese patients are lacking. METHODS The prospective, multicenter, observational J'xactly study enrolled patients with acute symptomatic/asymptomatic deep vein thromboses (DVT), pulmonary embolism (PE), or both, who were prescribed rivaroxaban. This subanalysis investigated patient characteristics and outcomes associated with rivaroxaban under-dosing. RESULTS Among 1016 evaluable patients, 667 (65.6%) received an initial standard dosage of rivaroxaban (30 mg/day) and 349 (34.4%) received an initial under-dosage (20 mg/day, n = 22; 15 mg/day, n = 282; and 10 mg/day, n = 45). Those receiving an under-dose had significantly lower body weight and slower pulse rate compared with the standard-dose group regardless of DVT or PE status. Under-dosing was common for distal DVTs, but less frequent for massive/submassive PEs. There were no differences between under-dose and standard-dose groups in the incidences of recurring symptomatic VTEs (DVT: 1.77% vs. 3.35% per patient-year, p = .138; PE: 0.84% vs. 2.84% per patient-year, p = .208) or major bleeding (DVT: 3.55% vs. 3.41% per patient-year, p = .960; PE: not observed vs. 2.83% per patient-year, p = .132). CONCLUSIONS In the real-world setting, rivaroxaban under-dosing for patients with VTE occurred in those with lower body weight, slower pulse rate, distal DVT, or non-massive PEs. There were no statistically significant differences in the clinical outcomes for patients received under-dose of rivaroxaban at the discretion of the physicians in the clinical practice compared with those received standard dose of rivaroxaban.

Abstract
AIMS The Model for End-stage Liver Disease eXcluding International normalized ratio (MELD-XI) is an established scoring system that reflects hepatorenal function. However, little is known about the prognostic value of changes in MELD-XI score during hospitalization in acute decompensated heart failure (ADHF). METHODS AND RESULTS We prospectively analysed 536 patients admitted for ADHF between January 2018 and December 2019. In the MELD-XI, 9.44 is the lowest possible score and considered to be normal, and values above 9.44 are classified as high. We calculated MELD-XI scores at admission and discharge and used them to divide patients into four groups depending on whether the score was high (>9.44) or normal (9.44) at each time point as follows: normal score at both measurements (persistently normal group, n = 99), high score at admission and normal score at discharge (high-to-normal group, n = 108), normal score at admission and high score at discharge (normal-to-high group, n = 24), and high score at both measurements (persistently high group, n = 305). The persistently high group had higher blood urea nitrogen, creatinine, and N-terminal pro-brain natriuretic peptide levels at both admission and discharge and significantly higher left ventricular end-diastolic, left atrial, right ventricular end-diastolic, and maximal inferior vena cava diameters at discharge. During the median follow-up period of 369 days (Q1, Q3: 97, 576), 231 (43.1%) patients reached the primary endpoint (a composite of all-cause death or re-hospitalization for heart failure). The Kaplan-Meier analysis revealed a significantly higher composite event rate in the persistently high group than in the persistently normal and high-to-normal groups (log-rank test, P < 0.001). Compared with the persistently high group, the high-to-normal group remained significantly associated with lower composite event risk after multivariate adjustment (hazard ratio, 0.30; 95% CI, 0.12-0.69; P = 0.004). CONCLUSIONS Our study suggests that changes in hepatorenal function during hospitalization are associated with the severity of heart failure and systemic congestion and that they provide useful information for predicting clinical outcomes in patients with ADHF.

Abstract
BACKGROUND The clinical efficacy of the Impella for high-risk percutaneous coronary intervention (PCI) and cardiogenic shock remains under debate. We thus sought to investigate the protective effects on the heart with the Impella's early use pre-PCI using cardiac magnetic resonance imaging (CMRI). METHODS We retrospectively evaluated the difference in the subacute phase CMR imaging results (19 ± 9 days after admission) between patients undergoing an Impella (n = 7) or not (non-Impella group: n = 18 [12 intra-aortic balloon pumps (1 plus veno-arterial extracorporeal membrane oxygenation) and 6 no mechanical circulation systems]) in broad anterior ST-elevation myocardial infarction (STEMI) cases. A mechanical circulation system was implanted pre-PCI. RESULTS No differences were found in the door-to-balloon time, peak creatine kinase, and hospital admission days between the Impella and non-Impella groups; however, the CMRI-derived left ventricular ejection fraction was significantly greater (45 ± 13% vs. 34 ± 7.6%, P = 0.034) and end-diastolic and systolic volumes smaller in the Impella group (149 ± 29 vs. 187 ± 41 mL, P = 0.006: 80 ± 29 vs. 121 ± 40 mL, P = 0.012). Although the global longitudinal peak strain did not differ, the global radial (GRS) and circumferential peak strain (GCS) were significantly higher in the IMPELLA than non-IMPELLA group. Greater systolic and diastolic strain rates (SRs) in the Impella than non-Impella group were observed in non-infarcted rather than infarcted areas. CONCLUSIONS Early implantation of an Impella before PCIs for STEMIs sub-acutely prevented cardiac dysfunction through preserving the GRS, GCS, and systolic and diastolic SRs in the remote myocardium. This study provided mechanistic insight into understanding the usefulness of the Impella to prevent future heart failure.

Abstract
AbstractRecent studies reported that a convolutional neural network (CNN; a deep learning model) can detect elevated pulmonary artery wedge pressure (PAWP) from chest radiographs, the diagnostic images most commonly used for assessing pulmonary congestion in heart failure. However, no method has been published for quantitatively estimating PAWP from such radiographs. We hypothesized that a regression CNN, an alternative type of deep learning, could be a useful tool for quantitatively estimating PAWP in cardiovascular diseases. We retrospectively enrolled 936 patients with cardiovascular diseases who had undergone right heart catheterization (RHC) and chest radiography and estimated PAWP by constructing a regression CNN based on the VGG16 model. We randomly categorized 80% of the data as training data (training group, n = 748) and 20% as test data (test group, n = 188). Moreover, we tuned the learning rate—one of the model parameters—by 5-hold cross-validation of the training group. Correlations between PAWP measured by RHC [ground truth (GT) PAWP] and PAWP derived from the regression CNN (estimated PAWP) were tested. To visualize how the regression CNN assessed the images, we created a regression activation map (RAM), a visualization technique for regression CNN. Estimated PAWP correlated significantly with GT PAWP in both the training (r = 0.76, P < 0.001) and test group (r = 0.62, P < 0.001). Bland–Altman plots found a mean (SEM) difference between GT and estimated PAWP of − 0.23 (0.16) mm Hg in the training and − 0.05 (0.41) mm Hg in the test group. The RAM showed that our regression CNN model estimated high PAWP by focusing on the cardiomegaly and pulmonary congestion. In the test group, the area under the curve (AUC) for detecting elevated PAWP (≥ 18 mm Hg) produced by the regression CNN model was similar to the AUC of an experienced cardiologist (0.86 vs 0.83, respectively; P = 0.24). This proof-of-concept study shows that regression CNN can quantitatively estimate PAWP from standard chest radiographs in cardiovascular diseases.

Abstract
This study aimed to investigate the relationship between ocular vascular resistance parameters, evaluated by laser speckle flowgraphy (LSFG), and systemic atherosclerosis, renal parameters and cardiac function in acute coronary syndrome (ACS) patients. We evaluated 53 ACS patients between April 2019 and September 2020. LSFG measured the mean blur rate (MBR) and ocular blowout time (BOT) and resistivity index (RI). 110 consequent patients without a history of coronary artery disease who visited ophthalmology as a control group. Significant positive correlations were observed between ocular RI and systemic parameters in ACS patients, including intima-media thickness (r = 0.34, P = 0.015), brachial-ankle pulse-wave velocity (r = 0.41, P = 0.002), cystatin C (r = 0.32, P = 0.020), and E/e’ (r = 0.34, P = 0.013). Ocular RI was significantly higher in the ACS group than in the control group in male in their 40 s (0.37 ± 0.02 vs. 0.29 ± 0.01, P < 0.001) and 50 s (0.36 ± 0.02 vs. 0.30 ± 0.01, P = 0.01). We found that the ocular RI was associated with systemic atherosclerosis, early renal dysfunction, and diastolic cardiac dysfunction in ACS patients, suggesting that it could be a useful non-invasive comprehensive arteriosclerotic marker.

Abstract
Instantaneous wave-free ratio (iFR) is a non-hyperemic coronary physiological index measured during the diastolic wave-free period. Although atrial fibrillation (AF) with beat-to-beat fluctuations can occur during diastole, the feasibility of iFR measurements during AF has previously been demonstrated. However, the effects of coronary circulation during AF on iFR measurements remain unknown. In addition, the pathophysiology of ischemia due to AF tachycardia requires further elucidation. We report a unique case of myocardial ischemia due to rapid AF, as indicated by the iFR pullback measurement and beat-to-beat analysis. When planning revascularization in patients with rapid AF, the ability of iFR to reflect ischemic stress due to AF tachycardia should be considered.

Abstract
A few studies have reported on recurrent myocarditis occurring more than twice in one patient. In this study, we present a recurrent "third time" acute myocarditis in a young female Japanese patient with a history of a definitive diagnosis of lymphocytic myocarditis by endomyocardial biopsy, cardiac magnetic resonance imaging (CMR), and catheter examination twice in the past. Although chest pain and an increase in the cardiac enzymes were observed the third time, no significant changes were noted in the 12-lead electrocardiogram (ECG), and a definitive diagnosis could be achieved by CMR. This case suggested that in patients with a history of myocarditis, if there is chest pain and elevated cardiac enzymes even without any changes in the 12-lead ECG, acute myocarditis should be considered, and CMR is useful for the differentiation.Only four case reports including this present case were found through the previous literatures. More than two recurrent episodes of myocarditis have been extremely rare, but all cases have typical chest symptoms and a troponin level increase, leading to a relatively benign prognosis.

Abstract
BACKGROUND Non-obstructive general angioscopy (NOGA) can be used to diagnose aortic atherosclerotic plaques. We examine the association between the number of aortic plaques detected by NOGA and the risk of subsequent cardiovascular events. METHODS The Evaluation of AtheroScleroTic and rupture events by Non-Obstructive General Angioscopy (EAST-NOGA) was a prospective cohort study of patients with suspected coronary artery disease who underwent NOGA. RESULTS Of the 577 patients who underwent NOGA, 532 (92%) completed the follow-up (median follow-up: 13 months, interquartile range: 12-16). The median number of plaques per person was 6 (interquartile range: 3-12), and 567 (98%) had at least one aortic plaque. During the 13-month follow-up, 38 (7.1%) patients had a primary composite endpoint [including cardiovascular death, myocardial infarction, stroke, peripheral artery disease (PAD), or worsening renal function], which was significantly associated with chronic kidney disease, a history of PAD, a lower hemoglobin level, and large numbers of aortic plaques [11 (5-17) vs. 6 (2-11), p = 0.003]. A receiver operating characteristic curve analysis for the number of aortic plaques predicting composite endpoints revealed that the cut-off value of aortic plaques was 12. After multivariate adjustment, the presence of ≥12 aortic plaques remained a significant predictor for composite endpoint events (hazard ratio 2.53, 95% confidence interval 1.26-5.04, p = 0.010). CONCLUSIONS The number of aortic plaques detected by NOGA may predict subsequent clinical events.

Abstract
The relationships between intracoronary imaging modalities and outcomes among Japanese patients with coronary artery disease (CAD) based on the type of medical facility providing outpatient care remain unclear. In this multicenter prospective study (SAKURA PCI Registry), we aimed to investigate the clinical outcomes of patients with CAD who underwent percutaneous coronary intervention (PCI) between April 2015 and December 2018. In this registry, we investigated differences in patient characteristics, intracoronary imaging modalities, and clinical outcomes between two types of medical facilities. Of the 414 patients enrolled in this registry, 196 were treated at two university hospitals, and 218 were treated at five community hospitals (median follow-up 11.0 months). The primary endpoint was clinically relevant events (CREs), including a composite of all-cause death, non-fatal myocardial infarction, clinically driven target lesion revascularization, stent thrombosis, stroke, and major bleeding. Patients treated at university hospitals had higher rates of diabetes (50% vs. 38%, p = 0.015) and malignant tumors (12% vs. 6%, p = 0.015) and more frequent use of multiple intracoronary imaging modalities than patients treated at community hospitals (21% vs. 0.5%, p < 0.001). The Kaplan-Meier incidence of CREs at 1 year was comparable between university hospitals and community hospitals (8.8% vs. 7.3%, p = 0.527, log-rank test). Despite the relatively higher risk among patients in university hospitals with frequent use of multi-intracoronary imaging modalities, adverse clinical events appeared to be comparable between patients with CAD treated at university and community hospitals in Japan.

Abstract
Liver stiffness (LS) assessed by ultrasound elastography reflects right-sided filling pressure and offers additional prognostic information in patients with acute decompensated heart failure (ADHF). However, the prognostic value of LS in heart failure (HF) with preserved ejection fraction (HFpEF) remains unclear. This study aimed to investigate the prognostic value of LS measured by two-dimensional shear wave elastography (2D-SWE) in patients with HFpEF.We prospectively enrolled 80 patients hospitalized for decompensated HFpEF between September 2019 and June 2020. Patients were categorized into three groups based on the tertile values of LS at discharge.The third tertile LS group had an older age; more advanced New York Heart Association functional class; higher total bilirubin, γ-glutamyl transferase (GGT), N-terminal pro-B type natriuretic peptide (NT pro-BNP), and Fibrosis-4 index; a larger right ventricle diastolic diameter, higher tricuspid regurgitation pressure gradient, and a larger maximal inferior vena cava diameter. During a median [interquartile range] follow-up period of 212 (82-275) days, 25 (31.2%) patients suffered composite end points (all-cause mortality and rehospitalization for worsening HF). The third tertile LS group had a significantly higher rate of composite end points (log-rank P = 0.002). A higher LS and the third tertile LS were significantly associated with the composite end points, even after adjusting for a conventional validated HF risk score and other previously reported prognostic risk factors.Increased LS measured by 2D-SWE reflects the severity of liver impairment by liver congestion and fibrosis, underlying right HF, and provides additional information for the prediction of poor outcomes in HFpEF.

Abstract
We have a great interest in the article in Journal of Atherosclerosis and Thrombosis by Suzuki et al. titled Complex Aortic Arch Atherosclerosis in Acute Ischemic Stroke Patients with Non-Valvular Atrial Fibrillation. The authors demonstrated that 38.7% transesophageal echocardiography-derived complex aortic arch plaques (CAPs) among 106 patients with acute ischemic strokes with atrial fibrillation (AF), suggesting that patients with acute ischemic stroke and AF often had CAPs. The atheromatous lesions at the aortic arch are one of the causes of ischemic strokes. The cause of acute ischemic strokes in patients with AF could not only be cardiogenic embolisms due to AF but also aortogenic embolisms due to CAPs. The possibility of concomitant CAPs should be considered for stroke patients with AF. Non-obstructive general angioscopy has the possibility to detect aortic plaques in the aortic arch more accurately than TEE and might help to diagnose atheromatous plaques and embolic materials in the aortic arch. Further studies are needed to elucidate the causes of ischemic strokes and are expected to improve the outcomes for acute ischemic strokes in patients with AF.

Abstract
AIMS Anomalous origin of the coronary artery (AOCA) with an inter-arterial course (IAC) between the great vessels poses a risk for a life-threatening cardiovascular event. We assessed, in a registry-based study, the clinical features, treatment strategies, and prognoses of life-threatening cardiovascular events ensuant to AOCA. METHODS AND RESULTS Included were 65 AOCA patients (48 men/17 women, aged 41 ± 23 years) from 40 clinical centres who had experienced sudden cardiac arrest (SCA) (n = 30), acute myocardial infarction (AMI) (n = 5), angina (n = 23), or syncope (n = 7). The anomalous vessel was the right coronary artery in 72% of patients and left coronary artery in 28%; the ostium was slit-like in 42%. Coronary luminal narrowing ≥75% was absent in patients with SCA or syncope (86% and 57%, respectively), but occlusion or narrowing was seen in those with AMI (100%) or angina (52%). Age ≤40 years, male sex, sporting activity, absence of prodromal symptoms, acutely angled (≤30°) take-off from the aorta, and absence of luminal narrowing of the IAC segment were associated with SCA in this patient group. Coronary vasospasm was inducible in 12 of 17 patients without coronary narrowing. Management included surgical revascularization (n = 26) percutaneous coronary intervention (n = 9), and medical treatment (n = 26). Four SCA patients died while hospitalized; no others died during the median 5.0 (range, 1.8-7.0)-year follow-up period. CONCLUSIONS In patients with AOCA, age ≤40 years, male sex, sporting activity, and an acute take-off angle appear to be risk factors for SCA. Appropriate management can be beneficial. Confirmation in a large-scale study is warranted.

Abstract
The relationship between the socioeconomic status, including the health insurance status, and prognosis of heart failure (HF) has been recognized as an important concept for stratifying the risk in HF patients and is gaining increasing attention worldwide even in countries with a universal healthcare system. However, the impact of the Japanese health insurance status on outcomes among patients admitted for acute HF has not been fully clarified. We enrolled 771 patients admitted for acute HF between January 2018 and December 2019 and collected data on the in-hospital mortality, length of the hospital stay, and cardiac events, defined as cardiovascular death and readmission for HF within 1 year after discharge. Patients were divided into two groups according to their insurance status, i.e., public assistance (n = 87) vs. other insurance (n = 684). The public assistance group was significantly younger and had a higher rate of diabetes, smoking, ischemic and hypertensive heart disease, and low estimated glomerular filtration rate (all P < 0.05). Pharmacological/invasive heart failure therapy, in-hospital mortality, and the 90-day cardiac event rate after discharge did not differ between the groups. However, the public assistance group had a significantly higher 1-year cardiac event rate than the other insurance groups (P = 0.025). After adjusting for covariates, public assistance was independently associated with the 1-year cardiac event rate (HR: 2.15, 95% CI: 1.42-3.26, P < 0.001). Acute HF patients covered by public assistance received the same quality of medical care, including invasive therapy. As a result, no health disparities were found in terms of the in-hospital mortality and 90-day cardiac event rate, unlike overseas surveys. Nevertheless, HF patients with public assistance had a higher risk for the long-term prognosis than those with other insurance. Comprehensive HF management is required post-discharge.

Abstract
The significance of microvessels within atherosclerotic plaques is not yet fully clarified. Associated with plaque vulnerability. The aim of this study is to examine tissue characteristics of plaque with microvessels detected by optical coherence tomography (OCT) by use of a commercially available color-coded intravascular ultrasound (IVUS) and coronary angioscopy (CAS). The subjects examined comprised of 44 patients with stable angina pectoris who underwent percutaneous coronary intervention. Microvessels were defined as a tiny tubule with a diameter of 50-300 µm detected over three or more frames in OCT. We compared the total volume of microvessels with tissue component such as fibrotic, lipidic, necrotic, and calcified volume and the number of yellow plaque. In IVUS analysis, % necrotic volume and % lipidic volume were significantly correlated and % fibrotic volume was inversely significantly correlated with the total volume of microvessel (r = 0.485, p = 0.0009; r = 0.401, p = 0.007; r = - 0.432, p = 0.003, respectively). The number of plaque with an angioscopic yellow grade of two or more was significantly correlated with the total volume of microvessel (r = 0.461, p = 0.002). The greater the luminal volume of microvessels, the more the percent content of necrotic/lipidic tissue volume within plaque and the more the number of yellow plaques. These data suggested that microvessels within coronary plaque might be related to plaque vulnerability.

Abstract
In this retrospective observational study, we have examined the incidence, characteristics, and treatment of serious myocardial infarction (MI) -associated mechanical complications (MCs) occurring in Japanese patients in this era of percutaneous coronary intervention (PCI), focusing on frailty, nutrition, and clinical implication of surgery. Included were 883 patients who, having suffered an MI, had been admitted to Nihon University Hospital between January 2013 and April 2020. Fifteen (1.70%) of these patients had suffered a potentially catastrophic MC-ventricular free wall rupture (VFWR, n = 8), ventricular septal rupture (VSR, n = 6), or papillary muscle rupture (PMR, n = 1). Factors associated with the MCs were age, poor nutritional status, a high Killip class, delayed diagnosis of MI, a high lactate concentration, a low thrombolysis in myocardial infarction flow grade, and single-vessel disease. Thirty-day mortality among MC patients was 60% (9/15): 87.5% associated with VFWR, 33.3% associated with VSR and 0% associated with PMR. On adjusted multivariate analysis, occurrence of an MC was independently associated with 30-day mortality. Despite a high surgical risk (EuroSCORE II: 11.8 ± 4.7) with less frailty, 30-day mortality was lower among patients whose MC was treated surgically than among those whose MC was treated conservatively (40.0% versus 100.0%, respectively; P = 0.044).Our data suggest that surgical intervention can save patients with a life-threatening MI-associated MC and should be considered, if they are not particularly frail.

Abstract
AIMS Smaller low-density lipoprotein (LDL) particle size has been suggested to result in the development of endothelial dysfunction, atherosclerosis, and in-stent restenosis (ISR); however, little is known regarding the impact of the LDL particle size on the neointima formation leading to ISR after everolimus-eluting stent (EES) implantation. METHODS In this study, we have included 100 patients to examine the relationship between an LDL-C/apolipoprotein B (Apo B) ≤ 1.2, reportedly representing the LDL particle size, and the neointimal characteristics using optical coherence tomography (OCT) and coronary angioscopy (CAS) during the follow-up coronary angiography (CAG) period (8.8±2.5 months) after EES implantation. We divided them into two groups: LDL-C/Apo B ≤ 1.2 group (low LDL-C/Apo B group, n=53) and LDL-C/Apo B >1.2 group (high LDL-C/Apo B group, n=47). RESULTS The low LDL-C/Apo B group had a significantly larger neointimal volume (12.8±5.3 vs. 10.3±4.9 mm3, p=0.021) and lower incidence of a neointimal homogeneous pattern (71 vs. 89 %), higher incidence of a neointimal heterogeneous pattern (25 vs. 9 %) (p=0.006) and higher prevalence of macrophage accumulation (9 vs. 2 %) (p=0.030) as assessed via OCT, and, as per the CAS findings, a higher prevalence of yellow grade ≥ 2 (grade 2; adjusted residual: 2.94, grade 3; adjusted residual: 2.00, p=0.017) than the high LDL-C/Apo B group. CONCLUSIONS A low LDL-C/Apo B ratio was found to be strongly associated with neointimal proliferation and neointimal instability evidenced chronically by OCT and CAS. An LDL-C/Apo B ≤ 1.2 will be of aid in terms of identifying high-risk patients after EES implantation.

Abstract
Non-obstructive general angioscopy (NOGA) images of severe aortic valve stenosis (AS) and atherosclerotic aorta were documented. Atheromatous embolization is known as an important complication of endovascular therapy for severe AS. However, it is hard to detect atherosclerotic changes of the aortic valve and atheromatous aorta related to them in the in-vivo setting. NOGA, which is a novel imaging modality for the aorta and aortic valves, can visualize atherosclerosis of aortic intima vividly. NOGA may play a role in risk stratification for atheromatous embolism with endovascular therapy. We reported a case of severe AS and atheromatous aorta to evaluate before an operation with NOGA.

Abstract
AIM Coronary plaque rupture is the main cause of acute coronary syndrome (ACS), but the role of blood flow features around plaque rupture for ACS is still unknown. The present study aimed to assess the relationship between the geometric configuration of ruptured plaque and ACS occurrence using computational fluid dynamics (CFD) by moving particle method in patients with coronary artery disease. METHODS In this study, 45 patients with coronary artery disease who underwent three-dimensional intravascular ultrasound (IVUS) and had a coronary ruptured plaque (24 plaques with provoked ACS, 21 without) were included. To compare the difference in blood flow profile around ruptured plaque between the patients with and without ACS, the IVUS images were analyzed via the novel CFD analysis. RESULTS There were no significant differences in localized flow profile around ruptured plaque between the two groups when the initial particle velocity was 10.0 cm/s corresponded to a higher coronary flow velocity at ventricular diastole. However, when it was 1.0 cm/s corresponded to lower coronary flow velocity at ventricular systole, particles with lower velocity (0 ≤ V ≤ 5 cm/s) were more prevalent around ACS-PR (p=0.035), whereas particles with higher velocity (10 ≤ V ≤ 20 cm/s) were more often detected in silent plaque ruptures (p=0.018). CONCLUSIONS Three-dimensional IVUS revealed that coronary plaque rupture was a complex one with a wide variety of its stereoscopic configuration, leading to various patterns of the local coronary flow profile. A novel CFD analysis suggested that the local flow was more stagnant around ACS-provoked ruptures than in silent ones.

Abstract
Ophthalmic carteolol is often used to treat glaucoma. Elderly patients with atrial fibrillation (AF) and chronic kidney disease (CKD) are common among the super-elderly in Japan. Because these patients are exposed to polypharmacy, they are at a high-risk of adverse drug interactions. We herein report an elderly patient with CKD who suffered bradycardia shock after the combined use of carteolol eye drops and verapamil for glaucoma and paroxysmal AF. This case highlights the fact that eye drops have a similar systemic effect to oral drugs, and especially in elderly patients with polypharmacy, drug interactions can unwittingly lead to serious events.

Abstract
Background:
SYNERGY is a thin-strut, platinum-chromium metal alloy stent with an ultrathin abluminal everolimus-eluting bioabsorbable polymer. EVOLVE II was a global randomized controlled trial that enrolled 1,684 patients treated with either a SYNERGY or durable polymer PROMUS Element Plus (PE+) everolimus-eluting stent, including 155 patients from Japanese sites. This substudy analyzed 5-year clinical outcomes in the Japanese and non-Japanese cohorts. Methods and Results:
Patients aged ≥18 years with ≤3 native coronary artery lesions (reference vessel diameter ≥2.25–≤4.00 mm; length ≤34 mm) in ≤2 major vessels were randomized 1 : 1 to receive either SYNERGY (n=74 patients in Japan) or PE+ (n=81 patients in Japan). Five-year target lesion failure (TLF) was observed in 8.3% SYNERGY- and 11.2% PE+-treated patients (P=0.54). There were no cardiac deaths, and rates of target lesion revascularization and myocardial infarction were comparable between treatment arms. One patient in the SYNERGY arm experienced a very late definite stent thrombosis (ST); no ST occurred in the PE+ arm (P=0.30). Despite differences in baseline clinical and lesion characteristics, the 5-year TLF rates were not significantly different in SYNERGY-treated patients either in (8.3%) or outside (14.8%) Japan (P=0.14). Conclusions:
In Japanese patients with coronary artery disease, SYNERGY showed comparable efficacy to PE+, with low rates of adverse events over 5 years. Similarly, 5-year clinical outcomes were favorable in Japanese vs. non-Japanese patients implanted with SYNERGY.
