Benefit of prehospital electrocardiogram on door-to-device time in ST-segment elevation myocardial infarction with cardiogenic shock: Data from the Kanagawa Acute Cardiovascular Registry. J Cardiol 2024:S0914-5087(24)00156-4. [PMID: 39153660 DOI: 10.1016/j.jjcc.2024.08.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 07/30/2024] [Accepted: 08/08/2024] [Indexed: 08/19/2024]
Abstract
BACKGROUND The benefit of prehospital 12‑lead electrocardiogram (PH-ECG) performed by emergency medical service personnel at the site of first medical contact (FMC) in patients with ST-segment elevation myocardial infarction (STEMI) with cardiogenic shock (CS-STEMI) remains unclear. This study aimed to investigate the effect of PH-ECG on door-to-device time in patients with CS-STEMI. METHODS This study enrolled CS-STEMI (Killip class IV) patients who were transferred directly to hospitals by ambulance (n = 517) from the Kanagawa Acute Cardiovascular Registry database. Patients were divided into PH-ECG (+) (n = 270) and PH-ECG (-) (n = 247) groups. Patients who experienced out-of-hospital cardiac arrest, who did not undergo emergent coronary intervention, or whose data were missing were excluded. Patient characteristics, FMC-to-door time, door-to-device time, and in-hospital mortality were compared between the groups. RESULTS The patient backgrounds of the PH-ECG (+) and PH-ECG (-) groups were comparable. The peak creatinine kinase level was greater in the PH-ECG (+) group than in the PH-ECG (-) group [2756 (1292-6009) IU/ml vs. 2270 (957-5258) IU/ml, p = 0.048]. The FMC-to-door time was similar between the two groups [25 (20-33) min vs. 27 (20-35) min, p = 0.530], while the door-to-device time was significantly shorter in the PH-ECG group [74 (52-103) min vs. 83 (62-111) min, p = 0.007]. In-hospital mortality did not differ between the two groups (18 % vs. 21 %, p = 0.405). Multivariable logistic regression analyses revealed that PH-ECG (+) was independently associated with a door-to-device time < 60 min [odds ratio (95 % confidence intervals): 1.88 (1.24-2.83), p = 0.003]. CONCLUSIONS PH-ECG was significantly associated with shorter door-to-device times in patients with CS-STEMI. Further studies with larger populations and more defined protocols are required to evaluate the utility of PH-ECG in patients with CS-STEMI.

Abstract
Background This study aimed to systematically evaluate voice symptoms during heart failure (HF) treatments and to exploratorily extract HF-related vocal biomarkers. Methods and Results This single-center, prospective study longitudinally acquired 839 audio files from 59 patients with acute decompensated HF. Patients' voices were analyzed along with conventional HF indicators (New York Heart Association [NYHA] class, presence of pulmonary congestion and pleural effusion on chest X-ray, and B-type natriuretic peptide [BNP]) and GOKAN scores based on the assessment of a cardiologist. Machine-learning (ML) models to estimate HF conditions were created using a Light Gradient Boosting Machine. Voice analysis identified 27 acoustic features that correlated with conventional HF indicators and GOKAN scores. When creating ML models based on the acoustic features, there was a significant correlation between actual and ML-derived BNP levels (r=0.49; P<0.001). ML models also identified good diagnostic accuracies in determining HF conditions characterized by NYHA class ≥2, BNP ≥300 pg/mL, presence of pulmonary congestion or pleural effusion on chest X-ray, and decompensated HF (defined as NYHA class ≥2 and BNP levels ≥300 pg/mL; accuracy: 75.1%, 69.1%, 68.7%, 66.4%, and 80.4%, respectively). Conclusions The present study successfully extracted HF-related acoustic features that correlated with conventional HF indicators. Although the data are preliminary, ML models based on acoustic features (vocal biomarkers) have the potential to infer various HF conditions, which warrant future studies.

Abstract
No medications have been reported to inhibit the progression of aortic valve stenosis (AS). The present study aimed to investigate whether evolocumab use is related to the slow progression of AS evaluated by serial echocardiography. This was a retrospective observational study from 2017 to 2022 at Yokohama City University Medical Center. Patients aged ≥ 18 with moderate AS were included. Exclusion criteria were (1) mild AS; (2) severe AS defined by maximum aortic valve (AV) velocity ≥ 4.0 m/s; and/or (3) no data of annual follow-up echocardiography. The primary endpoint was the association between evolocumab use and annual changes in the maximum AV-velocity or peak AV-pressure gradient (PG). A total of 57 patients were enrolled: 9 patients treated with evolocumab (evolocumab group), and the other 48 patients assigned to a control group. During a median follow-up of 33 months, the cumulative incidence of AS events (a composite of all-cause death, AV intervention, or unplanned hospitalization for heart failure) was 11% in the evolocumab group and 58% in the control group (P = 0.012). Annual change of maximum AV-velocity or peak AV-PG from the baseline to the next year was 0.02 (- 0.18 to 0.22) m/s per year or 0.60 (- 4.20 to 6.44) mmHg per year in the evolocumab group, whereas it was 0.29 (0.04-0.59) m/s per year or 7.61 (1.46-16.48) mmHg per year in the control group (both P < 0.05). Evolocumab use was associated with slow progression of AS and a low incidence of AS events in patients with moderate AS.

Intestinal ultrasound for intestinal Behçet disease reflects endoscopic activity and histopathological findings. Intest Res 2024; 22:297-309. [PMID: 39009376 PMCID: PMC11309824 DOI: 10.5217/ir.2023.00129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 01/11/2024] [Accepted: 02/26/2024] [Indexed: 07/17/2024] Open
Abstract
BACKGROUND/AIMS Intestinal Behçet disease is typically associated with ileocecal punched-out ulcers and significant morbidity and mortality. Intestinal ultrasound is a noninvasive imaging technique for disease monitoring. However, no previous reports have compared intestinal ultrasound with endoscopic ulcer activity or histopathological findings for intestinal Behçet disease. We evaluated the usefulness of intestinal ultrasound for assessing the activity of ileocecal ulcers in intestinal Behçet disease. METHODS We retrospectively compared intestinal ultrasound findings with 73 corresponding endoscopic images and 6 resected specimens. The intestinal ultrasound findings were assessed for 7 parameters (bowel wall thickness, vascularity [evaluated using the modified Limberg score with color Doppler], bowel wall stratification, white-plaque sign [strong hyperechogenic lines or spots], mesenteric lymphadenopathy, extramural phlegmons, and fistulas), and endoscopic ulcer activity was classified into active, healing, and scar stages. Histopathological findings were evaluated by consensus among experienced pathologists. RESULTS Bowel wall thickness (P< 0.001), vascularity (P< 0.001), loss of bowel wall stratification (P= 0.015), and white-plague sign (P= 0.013) were significantly exacerbated in the endoscopic active ulcer stage. Receiver operating characteristic curve analysis revealed that a bowel wall thickness of > 5.5 mm (sensitivity 89.7%, specificity 85.3%) was potentially useful for detecting active lesions. When compared with histopathological findings, an increase in bowel wall thickness reflected the ulcer marginal ridge, and the white-plaque sign reflected the ulcer bottom. CONCLUSIONS Intestinal ultrasound is useful for monitoring intestinal ulcer activity in intestinal Behçet disease.

Abstract
AIM Early and intensive low-density lipoprotein (LDL-C)-lowering therapy plays important roles in secondary prevention of acute coronary syndrome (ACS), but the treatment period for further clinical benefit remains undefined. This single-center, retrospective study explored LDL-C trajectory after ACS and its associations with subsequent cardiovascular events (CVE). METHODS In 831 patients with ACS, we evaluated LDL-C reduction during the first 2 months post-ACS as an index of early intervention and the area over the curve for LDL-C using 70 mg/dl as the threshold in the next 6 months (AOC-70) as a persistent intensity index. Patients were followed for a median of 3.0 (1.1-5.2) years for CVE, defined as the composite of cardiovascular death, non-fatal myocardial infarction, angina pectoris requiring revascularization, cerebral infarction, and coronary bypass grafting. RESULTS LDL-C decreased from baseline to 2 months post-ACS (107±38 mg/dl to 78±25 mg/dl, p<0.001) through high-intensity statin prescription (91.8%), while achieving rates of LDL-C <70 mg/dl at 2 months remained only 40.2% with no significant changes thereafter. During the follow-up period, CVE occurred in 200 patients. LDL-C reduction during the first 2 months and AOC-70 in the next 6 months were both associated with subsequent CVE risk (sub-HR [hazard ratio] [95% confidence interval]: 1.48 [1.16-1.89] and 1.22 [1.05-1.44]). Furthermore, early intervention followed by persistently intensive LDL-C-lowering therapy resulted in further CVE risk reduction. CONCLUSIONS The present study observed that achieving early and intensive LDL-C reduction within the first two months after ACS and maintaining it for the next six months suppressed subsequent CVE risk, suggesting the importance of early, intensive, and persistent LDL-C-lowering therapy in the secondary prevention of ACS.

Abstract
BACKGROUND A delayed and recurrent complete atrioventricular block (CAVB) is a life-threatening complication of transcatheter aortic valve replacement (TAVR). Post-TAVR evaluation may be important in predicting delayed and recurrent CAVB requiring permanent pacemaker implantation (PPI). The impact of new-onset right bundle-branch block (RBBB) after TAVR on PPI remains unknown. METHODS AND RESULTS In total, 407 patients with aortic stenosis who underwent TAVR were included in this analysis. Intraprocedural CAVB was defined as CAVB that occurred during TAVR. A 12-lead ECG was evaluated at baseline, immediately after TAVR, on postoperative days 1 and 5, and according to the need to identify new-onset bundle-branch block (BBB) and CAVB after TAVR. Forty patients (9.8%) required PPI, 17 patients (4.2%) had persistent intraprocedural CAVB, and 23 (5.7%) had delayed or recurrent CAVB after TAVR. The rates of no new-onset BBB, new-onset left BBB, and new-onset RBBB were 65.1%, 26.8%, and 4.7%, respectively. Compared with patients without new-onset BBB and those with new-onset left BBB, the rate of PPI was higher in patients with new-onset RBBB (3.4% versus 5.6% versus 44.4%, P<0.0001). On post-TAVR evaluation in patients without persistent intraprocedural CAVB, the multivariate logistic regression analysis showed that new-onset RBBB was a statistically significant predictor of PPI compared with no new-onset BBB (odds ratio [OR], 18.0 [95% CI, 5.94-54.4]) in addition to the use of a self-expanding valve (OR, 2.97 [95% CI, 1.09-8.10]). CONCLUSIONS Patients with new-onset RBBB after TAVR are at high risk for PPI.

Abstract
AIM Low-density lipoprotein cholesterol (LDL-C) level reduction is highly effective in preventing the occurrence of a cardiovascular event. Contrariwise, an inverse association exists between LDL-C levels and prognosis in some patients with cardiovascular diseases-the so-called "cholesterol paradox." This study aimed to investigate whether the LDL-C level on admission affects the long-term prognosis in patients who develop acute coronary syndrome (ACS) and to examine factors associated with poor prognosis in patients with low LDL-C levels. METHODS We enrolled 410 statin-naïve patients with ACS, whom we divided into low- and high-LDL-C groups based on an admission LDL-C cut-off (obtained from the Youden index) of 122 mg/dL. Endothelial function was assessed using the reactive hyperemia index 1 week after statin initiation. The primary composite endpoint included all-cause death, as well as myocardial infarction and ischemic stroke occurrences. RESULTS During a median follow-up period of 6.1 years, 76 patients experienced the primary endpoint. Multivariate Cox regression analysis revealed that patients in the low LDL-C group had a 2.3-fold higher risk of experiencing the primary endpoint than those in the high LDL-C group (hazard ratio, 2.34; 95% confidence interval, 1.29-4.27; p=0.005). In the low LDL-C group, slow gait speed (frailty), elevated chronic-phase high-sensitivity C-reactive protein levels (chronic inflammation), and endothelial dysfunction were significantly associated with the primary endpoint. CONCLUSIONS Patients with low LDL-C levels at admission due to ACS had a significantly worse long-term prognosis than those with high LDL-C levels; frailty, chronic inflammation, and endothelial dysfunction were poor prognostic factors.

Abstract
AIMS High platelet-derived thrombogenicity during the acute phase of ST-segment elevation myocardial infarction (STEMI) is associated with poor outcomes; however, the associated factors remain unclear. This study aimed to examine whether acute inflammatory response after STEMI affects platelet-derived thrombogenicity. METHODS This retrospective observational single-center study included 150 patients with STEMI who were assessed for platelet-derived thrombogenicity during the acute phase. Platelet-derived thrombogenicity was assessed using the area under the flow-pressure curve for platelet chip (PL-AUC), which was measured using the total thrombus-formation analysis system (T-TAS). The peak leukocyte count was evaluated as an acute inflammatory response after STEMI. The patients were divided into two groups: the highest quartile of the peak leukocyte count and the other three quartiles combined. RESULTS Patients with a high peak leukocyte count (>15,222/mm3; n=37) had a higher PL-AUC upon admission (420 [386-457] vs. 385 [292-428], p=0.0018), higher PL-AUC during primary percutaneous coronary intervention (PPCI) (155 [76-229] vs. 96 [29-170], p=0.0065), a higher peak creatine kinase level (4200±2486 vs. 2373±1997, p<0.0001), and higher PL-AUC 2 weeks after STEMI (119 [61-197] vs. 88 [46-122], p=0.048) than those with a low peak leukocyte count (≤ 15,222/mm3; n=113). The peak leukocyte count after STEMI positively correlated with PL-AUC during primary PPCI (r=0.37, p<0.0001). A multivariable regression analysis showed the peak leukocyte count to be an independent factor for PL-AUC during PPCI (β=0.26, p=0.0065). CONCLUSIONS An elevated leukocyte count is associated with high T-TAS-based platelet-derived thrombogenicity during the acute phase of STEMI.

Abstract
BACKGROUND Mechanical compression of cardiac conduction system by transcatheter heart valves leads to complete atrioventricular block (CAVB) after transcatheter aortic valve replacement (TAVR). Bulging of ventricular septum in the left ventricular outflow tract (LVOT) may be associated with greater compression of conduction system, leading to irreversible CAVB. OBJECTIVE This study aimed to investigate the association of ventricular septal bulging with TAVR-related CAVB and permanent pacemaker implantation (PPI). METHODS Among 294 consecutive patients with severe aortic stenosis who underwent TAVR between July 2017 and February 2023, 271 were included in the analysis. As a quantitative evaluation of bulging of the ventricular septum, the ratio of LVOT area to aortic annulus area (L/A ratio) was measured at the systolic phase of computed tomography images. RESULTS TAVR-related CAVB occurred in 64 patients (23.6%). Twenty-eight patients (10.3%) required PPI. The optimal thresholds of L/A ratio for predicting TAVR-related CAVB and PPI were 1.0181 and 0.985, respectively. Patients with less than the cut-off values had higher rate of TAVR-related CAVB and PPI than those above (28.3% vs 13.1%, p = 0.0063; 14.7% vs 4.4%, p = 0.0077, respectively). A multivariate analysis showed that L/A ratio < 1.0181 was an independent predictor of TAVR-related CAVB (odds ratio [OR] 2.65, p = 0.011), in addition to prior right bundle branch block (OR 3.76, p = 0.0005), use of a self-expanding valve (OR 1.99, p = 0.030), and short membranous septum length (OR 0.96, p = 0.037). Only L/A ratio < 0.985 was independently associated with PPI (OR 3.70, p = 0.011). CONCLUSION Low L/A ratio is a predictor of TAVR-related CAVB and PPI.

Abstract
Background: We retrospectively investigated the effects of the severity and classification of sleep-disordered breathing (SDB) on left ventricular (LV) function in patients with ST-segment elevation myocardial infarction (STEMI). Methods: A total of 115 patients with STEMIs underwent a sleep study using a multichannel frontopolar electroencephalography recording device (Sleep Profiler) one week after STEMI onset. We evaluated LV global longitudinal strain (LV-GLS) using two-dimensional echocardiography at one week and seven months. Patients were classified as no SDB (AHI < 5 events/h), obstructive SDB (over 50% of apnea events are obstructive), and central SDB (over 50% of apnea events are central). Due to the device's limitations in distinguishing obstructive from central hypopnea, SDB classification was based on apnea index percentages. Results: The obstructive apnea index (OAI) was significantly associated with LV-GLS at one week (r = 0.24, p = 0.027) and seven months (r = 0.21, p = 0.020). No such correlations were found for the central apnea index and SDB classification. Multivariable regression analysis showed that the OAI was independently associated with LV-GLS at one week (β = 0.24, p = 0.002) and seven months (β = 0.20, p = 0.008). Conclusions: OAI is associated with persistent LV dysfunction assessed by LV-GLS in STEMI.

Abstract
Objective Although malignant lymphoma (ML) can occur in every organ, diagnosing cardiac involvement without cardiac manifestations is difficult. We therefore investigated the incidence of cardiac involvement in ML in our hospital and clarified the transthoracic echocardiography (TTE) findings of cardiac involvement. Methods Patients with ML referred to our hospital between January 2013 and December 2019 were retrospectively reviewed. Patients During the study period, 453 patients were identified. The mean age was 64.9 years old, and 54% of the patients were men. Results Diffuse large B-cell lymphoma (DLBCL) was the most common lymphoma, followed by follicular lymphoma. Of the 453 patients, 394 (87.0%) underwent TTE at the initial diagnosis or during the clinical course. The performance rates of TTE in DLBCL, Hodgkin lymphoma, and mantle cell lymphoma were above 90%. Cardiac involvement was detected in 6 (five with DLBCL and one with B-cell lymphoma) (1.5%) of the 394 patients who underwent TTE. The involved lesions of the heart varied, and five patients had pericardial effusion. Five patients had a preserved left ventricular ejection fraction. All patients were treated with chemotherapy, and some were treated with radiation and surgery. Conclusion Cardiac involvement was observed in six (1.5%) of the patients with ML who underwent TTE. B-cell lymphoma, especially DLBCL, is a common ML with cardiac involvement. Although five patients had pericardial effusion, the involved lesions of the heart were not uniform. TTE is a useful imaging modality to noninvasively and repeatedly evaluate the tumor characteristics, response to ML treatment, and cardiac function.

Background Contradictions between management modalities of type A acute aortic dissection (TAAAD) and ST-elevation-myocardial infarction (STEMI) may result in clinical catastrophe. Therefore, we aimed to explore which 2-dimensional echocardiography (2DE) findings are optimal for differentiating TAAAD from STEMI. Methods and Results This study included 340 patients with STEMI and 340 patients with TAAAD who underwent 2DE in the emergency department between 2012 and 2021. The proximal ascending aorta (PAA) diameter and other echocardiographic parameters were analyzed. PAA diameters were measured at 4 levels in the parasternal view: Valsalva, the sinotubular junction (STJ), the PAA at 1 cm above the STJ, and the PAA at 2 cm above the STJ. Receiver-operating characteristic curve analysis showed that Valsalva, STJ, PAA at 1 cm above the STJ, and PAA at 2 cm above the STJ were significant predictors of TAAAD (areas under the curve: 0.777, 0.924, 0.965, and 0.975, respectively; P<0.001) with the respective cutoff values of 39.4, 38.5, 39.8, and 41.2 mm. Multivariable analysis suggested that all 2DE parameters were significant predictors of TAAAD. Among the 2DE parameters examined, the incorporation of PAA at 2 cm above the STJ to clinical indicators exhibited the most significant diagnostic capability (C-statistics, 0.97; net reclassification improvement, 1.81; integrated discrimination improvement, 0.61). When only TAAAD with coronary malperfusion and STEMI were analyzed, the diagnostic utility of PAA at 1 cm above the STJ was evident (C-statistics, 0.99; net reclassification improvement, 1.79; integrated discrimination improvement, 0.67), with PAA at 2 cm above the STJ ranking second in diagnostic significance (C-statistics, 0.99; net reclassification improvement, 1.12; integrated discrimination improvement, 0.66). Conclusions PAA measurements were the most beneficial for diagnosing TAAAD in all 2DE findings and TAAAD from STEMI.

Prognostic importance of glycemic variability on left ventricular reverse remodeling after the first episode of ST-segment elevation myocardial infarction. Cardiovasc Diabetol 2023; 22:202. [PMID: 37542320 PMCID: PMC10403862 DOI: 10.1186/s12933-023-01931-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Accepted: 07/20/2023] [Indexed: 08/06/2023] Open
Abstract
BACKGROUND This study aimed to investigate the effect of glycemic variability (GV), determined using a continuous glucose monitoring system (CGMS), on left ventricular reverse remodeling (LVRR) after ST-segment elevation myocardial infarction (STEMI). METHODS A total of 201 consecutive patients with STEMI who underwent reperfusion therapy within 12 h of onset were enrolled. GV was measured using a CGMS and determined as the mean amplitude of glycemic excursion (MAGE). Left ventricular volumetric parameters were measured using cardiac magnetic resonance imaging (CMRI). LVRR was defined as an absolute decrease in the LV end-systolic volume index of > 10% from 1 week to 7 months after admission. Associations were also examined between GV and LVRR and between LVRR and the incidence of major adverse cardiovascular events (MACE; cardiovascular death, acute coronary syndrome recurrence, non-fatal stroke, and heart failure hospitalization). RESULTS The prevalence of LVRR was 28% (n = 57). The MAGE was independent predictor of LVRR (odds ratio [OR] 0.98, p = 0.002). Twenty patients experienced MACE during the follow-up period (median, 65 months). The incidence of MACE was lower in patients with LVRR than in those without (2% vs. 13%, p = 0.016). CONCLUSION Low GV, determined using a CGMS, was significantly associated with LVRR, which might lead to a good prognosis. Further studies are needed to validate the importance of GV in LVRR in patients with STEMI.

Abstract
BACKGROUND An arteriovenous fistula (AVF) is the most frequently used dialysis access for haemodialysis. However, it can cause volume loading for the heart and may induce circulatory failure when performed in patients with low cardiac function. This study aimed to characterise patients with low cardiac function when initiating dialysis and determine how cardiac function changes after the dialysis access surgery. METHODS We conducted a retrospective observational study at two centres incorporating 356 patients with end-stage kidney disease who underwent echocardiography before the dialysis access surgery. RESULTS An AVF and a subcutaneously fixed superficial artery were selected in 70.4% and 23.5% of 81 patients with reduced/mildly reduced (< 50%) left ventricular ejection fraction (LVEF), respectively, and in 94.2% and 1.1% of 275 patients with preserved (≥ 50%) LVEF (p < 0.001), respectively. Follow-up echocardiography was performed in 70.4% and 38.2% of patients with reduced/mildly reduced and preserved LVEF, respectively, which showed a significant increase in LVEF (41 ± 9-44 ± 12%, p = 0.038) in patients with reduced/mildly reduced LVEF. LVEF remained unchanged in 12 patients with reduced/mildly reduced LVEF who underwent subcutaneously fixed superficial artery (30 ± 10-32 ± 15%, p = 0.527). Patients with reduced/mildly reduced LVEF had lower survival rates after surgery than those with preserved LVEF (p = 0.021 for log-rank). CONCLUSION The LVEF subcategory was associated with dialysis access selection. After the dialysis access surgery, LVEF was increased in patients with reduced/mildly reduced LVEF. These results may help select dialysis access for patients initiating dialysis.

Abstract
BACKGROUNDS Recently, there has been increasing awareness that bleeding may lead to adverse outcomes. Endothelial dysfunction is associated with increased risk of cardiovascular and bleeding events. This study aimed to investigate the association of endothelial dysfunction with major bleeding and specific causes of death in addition to major adverse cardiovascular events in patients with acute coronary syndrome. METHODS This single-centre retrospective observational study was conducted at a tertiary-care hospital; patients with acute coronary syndrome were included between June 2010 and November 2014 (median follow-up, 6.1 years). The reactive hyperaemia index was assessed before their discharge; reactive hyperaemia index <1.67 was defined as endothelial dysfunction. The main outcomes were the incidence of major bleeding, all-cause death, cardiovascular death, non-cardiovascular death, resuscitated cardiac arrest, non-fatal myocardial infarction, non-fatal stroke, and hospitalisation for heart failure. RESULTS Among the included 674 patients with acute coronary syndrome, 264 (39.2%) had endothelial dysfunction. Multivariable Cox-hazard analyses revealed an independent predictive value of endothelial dysfunction for major bleeding (hazard ratio 2.29, 95% confidence interval 1.17-4.48, P = 0.016) and major adverse cardiovascular events (hazard ratio 2.04, 95% confidence interval 1.43-2.89, P < 0.001). The endothelial dysfunction group patients had a 2.5-fold greater risk of cardiovascular death; however, no association was found with non-cardiovascular death. CONCLUSION Endothelial dysfunction assessed using reactive hyperaemia index predicted future major cardiovascular event as well as major bleeding and cardiovascular death in patients with acute coronary syndrome.

Abstract
BACKGROUND The access site for primary percutaneous coronary intervention (PCI) for patients with ST-elevation myocardial infarction (STEMI) recently shifted from femoral to radial. However, few real-world data on Japanese patients exist. METHODS To elucidate the clinical selection and impact of the access site in STEMI patients, we analyzed a Japanese observational prospective multicenter registry of acute myocardial infarction (K-ACTIVE: Kanagawa ACuTe cardIoVascular rEgistry) in 2015 to 2021. Data were analyzed in the entire population and a propensity score-matched population adjusted for confounding factors. Major adverse cardiac event (MACE) was defined as cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Bleeding Academic Research Consortium (BARC) type 3 or 5 was used to assess bleeding events. MACE plus BARC type 3 or 5 bleeding were considered composite events. Clinical outcomes were followed for 30 days. RESULTS The 6802 STEMI patients included 4786 patients with radial access (70.3 %) and 2016 with femoral access (29.7 %). Femoral access tended to be selected for more severe conditions than radial access. The median door-to-device time in the radial access group was significantly shorter than the femoral access group in the entire population (75 min versus 79 min, p < 0.01). After propensity score matching (each group, n = 1208), the incidence of MACE tended to be lower in the radial access group [risk ratio (RR) 0.83, 95 % confidence interval (CI) 0.63-1.09, p = 0.17]. The incidence of BARC 3 or 5 bleeding was significantly less in the radial access group (RR 0.47, 95%CI 0.23-0.97, p = 0.04). The incidence of composite events was significantly less in the radial access group (RR 0.74, 95%CI 0.57-0.96, p = 0.02). CONCLUSION In STEMI patients undergoing primary PCI, in comparison to femoral access, radial access reduced composite events in the entire population and the matched population, through a reduction in MACE and BARC 3 or 5 bleeding.

Abstract
BACKGROUND Rapidly progressive, extensive myocardial injury/infarction (RPEMI) beyond the concept of wave-front phenomenon can be observed even when achieving timely reperfusion; however, the pathogenesis of RPEMI remains unknown. This retrospective study investigated clinical and lesion characteristics of RPEMI, focusing on culprit-lesion morphology (CLM). METHODS Among patients with extensive anterior-wall ST-segment elevation myocardial infarction due to proximal left anterior descending artery lesions who had reperfusion within 3 hours of symptom onset, 60 patients undergoing both intravascular ultrasound and cardiac magnetic resonance imaging were enrolled. Myocardial injury/infarction before reperfusion therapy was assessed by QRS scores at hospitalization electrocardiogram, and the extent of myocardial injury/infarction was evaluated by cardiac magnetic resonance imaging, which measured area at risk, infarct size, myocardial salvage index, microvascular obstruction, and left ventricular ejection fraction. RPEMI was defined as lower left ventricular ejection fraction (less median value) with microvascular obstruction. RESULTS Despite comparable onset-to-door and onset-to-reperfusion times and area at risk, patients with RPEMI showed higher QRS scores at hospitalization (5 [4.3-6] versus 3 [2-4], P<0.001) and infarct size (26.5±9.1 versus 20.4±10.5%, P=0.04), and a tendency toward lower myocardial salvage index (0.27±0.14 versus 0.36±0.20, P=0.10) compared with those without. Patients with versus without RPEMI more frequently observed specific CLM on intravascular ultrasound, characterized by the combination of vulnerable plaques, plaque ruptures, and/or large thrombi. When stratified by CLM-score composed of these 3 criteria, higher CLM-scores were or tended to be associated with higher QRS scores and incidence of RPEMI. In multivariate analyses including no-reflow phenomenon and final coronary-flow deterioration, increased CLM-score (≥2) was independently associated with high QRS scores and RPEMI (odd ratio 11.25 [95% CI, 2.43-52.00]; P=0.002). CONCLUSIONS Vulnerable CLM was a consistent determinant of advanced myocardial injury/infarction both before and after reperfusion therapy and may play a pivotal role in the development of RPEMI.

Abstract
Japan has reported a relatively small number of COVID-19 cases. Because not all infected persons receive diagnostic tests for COVID-19, the reported number must be lower than the actual number of infections. We assessed SARS-CoV-2 seroprevalence by analyzing >60,000 samples collected in Japan (Tokyo Metropolitan Area and Hokkaido Prefecture) during February 2020–March 2022. The results showed that ≈3.8% of the population had become seropositive by January 2021. The seroprevalence increased with the administration of vaccinations; however, among the elderly, seroprevalence was not as high as the vaccination rate. Among children, who were not eligible for vaccination, infection was spread during the epidemic waves caused by the SARS-CoV-2 Delta and Omicron variants. Nevertheless, seroprevalence for unvaccinated children <5 years of age was as low as 10% as of March 2022. Our study underscores the low incidence of SARS-CoV-2 infection in Japan and the effects of vaccination on immunity at the population level.

Abstract
AIMS Reduced skeletal muscle mass is a major component of sarcopenia, associated with impaired exercise capacity and poor prognosis in patients with heart failure (HF). Measurement of skeletal muscle mass by dual-energy X-ray absorptiometry may be affected by fluid retention, typically in the patients' lower extremities. The aim of the present study was to elucidate the association between upper and lower extremity skeletal muscle mass (USM and LSM) and all-cause mortality in hospitalized patients with HF, after discharge. METHODS This was a single-centre observational cohort study of 418 patients (59% were men) admitted with a diagnosis of HF (71 ± 13 years), with a left ventricular ejection fraction of 39 ± 16%. USM and LSM were measured by dual-energy X-ray absorptiometry with patients in a stable state after decongestion therapy. RESULTS The USM and LSM were 5.29 ± 1.18 and 13.78 ± 3.20 kg for men and 3.37 ± 0.68 and 9.19 ± 1.80 kg for women. A positive correlation was obtained between USM and LSM with mid-upper arm circumference (r = 0.684, P < 0.001) and calf circumference (r = 0.822, P < 0.001), respectively. During a median follow-up of 37 months, 92 (22.0%) of the 418 patients died. A Kaplan-Meier analysis revealed that sex-specific quartiles of USM/height2 and LSM/height2 were associated with all-cause mortality (both P < 0.001 by the log-rank test). In Cox models adjusted by age, sex, creatinine, haemoglobin, NYHA class, and height2 , the hazard ratio with 95% confidence intervals for all-cause mortality was 0.557 [0.393-0.783] (P < 0.001) for USM per 1 kg, and 0.783 [0.689-0.891] (P < 0.001) for LSM per 1 kg. The receiver-operator-characteristic curve analysis showed a comparable area under the curve between the USM/height2 and LSM/height2 (0.557 vs. 0.568, P = 0.562) in predicting all-cause mortality. The ratio of USM to LSM was significantly lower in 37 patients with residual leg oedema than in the 360 patients without oedema (36.1% vs. 38.1%, P = 0.004), suggesting the influence of oedema on measured LSM. CONCLUSIONS Both USM and LSM had a prognostic implication on mortality after discharge in HF, even though LSM may have been affected by leg oedema. These findings indicate that clinicians should not ignore a patient's USM or LSM in the prognostication of patients with HF.

Abstract
Background and objective
A cytokine storm is caused by inflammatory cells, including pro-inflammatory macrophage phenotype (M1), and play a critical role in the pathogenesis of COVID-19, in which diffuse alveolar damage occurs in the lungs due to oxidative stress exposure. Heme oxygenase (HO)-1 is a stress-induced protein produced by the anti-inflammatory / anti-oxidative macrophage phenotype (M2), which also produces soluble CD163 (sCD163). In our study, we investigated and determined that serum HO-1 can be a predictive biomarker for assessing both the severity and the outcome of COVID-19 patients.
Method
The serum concentrations of HO-1 and sCD163 of COVID-19 patients were measured on admission. The relationship between these biomarkers and other clinical parameters and outcomes were evaluated.
Results
Sixty-four COVID-19 patients (11 mild, 38 moderate, and 15 severe cases) were assessed. The serum HO-1 tended to increase (11.0 ng/mL vs. 24.3 ng/mL vs. 59.6 ng/mL with severity). Serum HO-1 correlated with serum lactate dehydrogenase (R = 0.422), C-reactive protein (R = 0.463), and the ground glass opacity (GGO) and consolidation score (R = 0.625) of chest computed tomography. The serum HO-1 showed a better area under the curve (AUC) for predicting ICU admission than the serum sCD163 (HO-1; 0.816 and sCD163; 0.743). In addition, composite parameters including serum HO-1 and the GGO and consolidation score showed a higher AUC for predicting ICU admission than the AUC of a single parameter.
Conclusion
Clinically, serum HO-1, reflecting the activation of M2, could be a very useful marker for evaluating disease severity and predicting prognoses for COVID-19 patients. In addition, controlling activated M2 might be a preventative COVID-19 therapeutic target.

Abstract
LV mechanical dispersion is a measure of regional heterogeneity of myocardial contraction. LV mechanical dispersion has been reported as an important prognosticator in STEMI. 3D speckle tracking enables us to precisely measure LV mechanical dispersion. LV mechanical dispersion by 3D speckle tracking can precisely predict prognosis.
Background The role of left ventricular (LV) mechanical dispersion estimated after an ST elevation acute myocardial infarction (STEMI) remains unclear. Methods The study participants were 208 consecutive patients (152 men, age = 72 years) presenting with STEMI for the first time who underwent primary percutaneous coronary intervention (PCI) within 12 h of STEMI onset. Within 48 h of PCI (mean = 24 h), 2D and 3D speckle-tracking echocardiography were performed. The global longitudinal strain (GLS) was calculated using 3D (3D-GLS) and 2D (2D-GLS) speckle tracking. Mechanical dispersion was defined using the standard deviation (SD) of the time to regional peak longitudinal strain (LS) for all 16 segments for both 2D-STE and 3D-STE (2D-LS-SD, 3D-LS-SD). Infarct size was estimated by Tc99m-sestamibi as the total area of < 50% of the uptake area at 2 weeks. The patients were followed up for a longer period of time (median118months) and checked for major adverse cardiac events (MACE: cardiac death, heart failure). Results During follow-up, 55 patients experienced MACE. The cut-off values were determined using receiver operating characteristic curves. The multivariate analysis revealed that a 3D-LS-SD > 56.7 ms was a significant predictor of MACEs (hazard ratio = 1.991, 95% confidence interval 1.033–3.613, p = 0.03), but 2D-LS-SD > 58.1 ms was not an independent predictor of MACEs (hazard ratio = 1.577, 95% confidence interval 0.815–3.042, p = 0.1). Furthermore, the combination of 3D-GLS and 3D-LS-SD had accurate predictability for MACE, as shown by the Kaplan-Meier curves (log rank, χ2 = 94.1, p < 0.0001). Conclusions LV mechanical dispersion besides 3D-GLS assessed by 3D-STE immediately after PCI can predict long-term prognosis.

Abstract
BACKGROUND The role of left atrial (LA) function in the long-term prognosis of ST-elevation acute myocardial infarction (STEMI) is still unclear.Methods and Results: Percutaneous coronary intervention (PCI) was performed in 433 patients with the first episode of STEMI within 12 h of onset. The patients underwent echocardiography 24 h after admission. LA reservoir strain and other echocardiographic parameters were analyzed. Follow up was performed for up to 10 years (mean duration, 91 months). The primary endpoint was major adverse cardiovascular events (MACE): cardiac death or hospitalization due to heart failure (HF). MACE occurred in 90 patients (20%) during the follow-up period. Multivariate Cox hazard analyses showed LA reservoir strain, global longitudinal strain (GLS), age and maximum B-type natriuretic peptide (BNP) were the significant predictors of MACE. Kaplan-Meier curves demonstrated that LA reservoir strain <25.8% was a strong predictor (Log rank, χ2=76.7, P<0.0001). Net reclassification improvement (NRI) demonstrated that adding LA reservoir strain had significant incremental effect on the conventional parameters (NRI and 95% CI: 0.24 [0.11-0.44]) . When combined with GLS >-11.5%, the patients with LA reservoir strain <25.8% were found to be at extremely high risk for MACE (Log rank, χ2=126.3, P<0.0001). CONCLUSIONS LA reservoir strain immediately after STEMI onset was a significant predictor of poor prognosis in patients, especially when combined with GLS.
