Abstract
BACKGROUND Percutaneous coronary intervention (PCI) is considered less safe in patients with reduced ejection fraction (EF), an impression based on older data. Whether the safety and durability of contemporary PCI are different in patients with reduced EF compared with normal EF patients is unknown. METHODS Patients from the BIOFLOW II, IV and V clinical trials were grouped as normal EF (≥50%) and reduced EF (30%-50%). Using multivariable logistic regression and cox proportional hazards regression, we determined relations of EF category with procedural safety (a composite of cardiac death, myocardial infarction, stroke and urgent coronary artery bypass grafting within 30 days of PCI) and target lesion failure (TLF; comprising cardiac death, target vessel myocardial infarction, target vessel revascularization within 1 year of PCI) respectively. In sensitivity analyses, we regrouped patients into EF < 45% and ≥55% and repeated the aforementioned analyses. RESULTS In 1685 patients with normal EF (mean age 65 years; 27% women; mean EF 61%) and 259 with low EF (mean age 64 years; 17% women; mean EF 41%), 101 safety and 148 TLF events occurred. Compared with patients in the normal EF group, those with reduced EF had neither a statistically significant higher proportion of safety events, nor a higher multivariable-adjusted risk for such events. Similarly, patients with reduced EF and normal EF did not differ in terms of TLF event proportions or multivariable-adjusted risk for TLF. The results were similar in sensitivity analyses with EF groups redefined to create a 10% between-group EF separation. CONCLUSION PCI safety and durability outcomes are similar in patients with mild-moderately reduced EF and normal EF.

Abstract
INTRODUCTION Percutaneous coronary intervention for complex coronary disease is associated with a high risk of cardiogenic shock. This can cause harm and limit the quality of revascularization achieved, especially when left ventricular function is impaired at the outset. Elective percutaneous left ventricular unloading is increasingly used to mitigate adverse events in patients undergoing high-risk percutaneous coronary intervention, but this strategy has fiscal and clinical costs and is not supported by robust evidence. METHODS CHIP-BCIS3 (Controlled Trial of High-Risk Coronary Intervention With Percutaneous Left Ventricular Unloading) is a prospective, multicenter, open-label randomized controlled trial that aims to determine whether a strategy of elective percutaneous left ventricular unloading is superior to standard care (no planned mechanical circulatory support) in patients undergoing nonemergent high-risk percutaneous coronary intervention. Patients are eligible for recruitment if they have severe left ventricular systolic dysfunction, extensive coronary artery disease, and are due to undergo complex percutaneous coronary intervention (to the left main stem with calcium modification or to a chronic total occlusion with a retrograde approach). Cardiogenic shock and acute ST-segment-elevation myocardial infarction are exclusions. The primary outcome is a hierarchical composite of all-cause death, stroke, spontaneous myocardial infarction, cardiovascular hospitalization, and periprocedural myocardial infarction, analyzed using the win ratio. Secondary outcomes include completeness of revascularization, major bleeding, vascular complications, health economic analyses, and health-related quality of life. A sample size of 250 patients will have in excess of 80% power to detect a hazard ratio of 0.62 at a minimum of 12 months, assuming 150 patients experience an event across all follow-up. CONCLUSIONS To date, 169 patients have been recruited from 21 National Health Service hospitals in the United Kingdom, with recruitment expected to complete in 2024.

Abstract
Background: Angiopoietin-like 2 (ANGPTL2) is a pro-inflammatory and pro-oxidant circulating protein that predicts and promotes chronic inflammatory diseases such as atherosclerosis in humans. Transgenic murine models demonstrated the deleterious role of ANGPTL2 in vascular diseases, while deletion of ANGPTL2 was protective. The nature of its role in cardiac tissues is, however, less clear. Indeed, in adult mice knocked down (KD) for ANGPTL2, we recently reported a mild left ventricular (LV) dysfunction originating from a congenital aortic valve stenosis, demonstrating that ANGPTL2 is essential to cardiac development and function. Hypothesis: Because we originally demonstrated that the KD of ANGPTL2 protected vascular endothelial function via an upregulation of arterial NOX4, promoting the beneficial production of dilatory H2O2, we tested the hypothesis that increased cardiac NOX4 could negatively affect cardiac redox and remodeling and contribute to LV dysfunction observed in adult Angptl2-KD mice. Methods and results: Cardiac expression and activity of NOX4 were higher in KD mice, promoting higher levels of cardiac H2O2 when compared to wild-type (WT) mice. Immunofluorescence showed that ANGPTL2 and NOX4 were co-expressed in cardiac cells from WT mice and both proteins co-immunoprecipitated in HEK293 cells, suggesting that ANGPTL2 and NOX4 physically interact. Pressure overload induced by transverse aortic constriction surgery (TAC) promoted LV systolic dysfunction in WT mice but did not further exacerbate the dysfunction in KD mice. Importantly, the severity of LV systolic dysfunction in KD mice (TAC and control SHAM) correlated with cardiac Nox4 expression. Injection of an adeno-associated virus (AAV9) delivering shRNA targeting cardiac Nox4 expression fully reversed LV systolic dysfunction in KD-SHAM mice, demonstrating the causal role of NOX4 in cardiac dysfunction in KD mice. Targeting cardiac Nox4 expression in KD mice also induced an antioxidant response characterized by increased expression of NRF2/KEAP1 and catalase. Conclusion: Together, these data reveal that the absence of ANGPTL2 induces an upregulation of cardiac NOX4 that contributes to oxidative stress and LV dysfunction. By interacting and repressing cardiac NOX4, ANGPTL2 could play a new beneficial role in the maintenance of cardiac redox homeostasis and function.

Abstract
Takotsubo cardiomyopathy (TCM) is characterized by severe left ventricular dysfunction. It presents as an acute coronary syndrome; however, the difference lies in the lack of coronary artery obstruction during a coronary angiogram. The left ventricular dysfunction extends beyond the area supplied with concordant coronary arteries. We describe a case of a 41-year-old female evaluated for acute coronary syndrome, later diagnosed with a unique reverse subtype of TCM.

Abstract
BACKGROUND Peripartum cardiomyopathy, one of the most fatal conditions during delivery, results in heart failure secondary to left ventricular systolic dysfunction. Left ventricular dysfunction can result in abnormalities in electrocardiography. However, the usefulness of electrocardiography in the identification of peripartum cardiomyopathy in pregnant women remains unclear. OBJECTIVE This study aimed to evaluate the effectiveness of a 12-lead electrocardiography-based artificial intelligence/machine learning-based software as a medical device for screening peripartum cardiomyopathy. STUDY DESIGN This retrospective cohort study included pregnant women who underwent transthoracic echocardiography between a month before and 5 months after delivery and underwent 12-lead electrocardiography within 30 days of echocardiography between December 2011 and May 2022 at Seoul National University Hospital. The performance of 12-lead electrocardiography-based artificial intelligence/machine learning analysis (AiTiALVSD software; version 1.00.00, which was developed to screen for left ventricular systolic dysfunction in the general population) was evaluated for the identification of peripartum cardiomyopathy. In addition, the performance of another artificial intelligence/machine learning algorithm using only 1-lead electrocardiography to detect left ventricular systolic dysfunction was evaluated in identifying peripartum cardiomyopathy. The results were obtained under a 95% confidence interval and considered significant when P<.05. RESULTS Among the 14,557 women who delivered during the study period, 204 (1.4%) underwent transthoracic echocardiography a month before and 5 months after delivery. Among them, 12 (5.8%) were diagnosed with peripartum cardiomyopathy. The results showed that AiTiALVSD for 12-lead electrocardiography was highly effective in detecting peripartum cardiomyopathy, with an area under the receiver operating characteristic of 0.979 (95% confidence interval, 0.953-1.000), an area under the precision-recall curve of 0.715 (95% confidence interval, 0.499-0.951), a sensitivity of 0.917 (95% confidence interval, 0.760-1.000), a specificity of 0.927 (95% confidence interval, 0.890-0.964), a positive predictive value of 0.440 (95% confidence interval, 0.245-0.635), and a negative predictive value of 0.994 (95% confidence interval, 0.983-1.000). In addition, a 1-lead (lead I) artificial intelligence/machine learning algorithm showed excellent performance; the area under the receiver operating characteristic, area under the precision-recall curve, sensitivity, specificity, positive predictive value, and negative predictive value were 0.944 (95% confidence interval, 0.895-0.993), 0.520 (95% confidence interval, 0.319-0.801), 0.833 (95% confidence interval, 0.622-1.000), 0.880 (95% confidence interval, 0.834-0.926), 0.303 (95% confidence interval, 0.146-0.460), and 0.988 (95% confidence interval, 0.972-1.000), respectively. CONCLUSION The 12-lead electrocardiography-based artificial intelligence/machine learning-based software as a medical device (AiTiALVSD) and 1-lead algorithm are noninvasive and effective ways of identifying cardiomyopathies occurring during the peripartum period, and they could potentially be used as highly sensitive screening tools for peripartum cardiomyopathy.

Abstract
AIMS Explore the cardiovascular effects of long-term anabolic-androgenic steroid (AAS)-use in both current and former weightlifting AAS-users, and estimate the occurrence of severe reduced myocardial function and the impact of duration and amount of AAS. METHODS In this cross-sectional study 101 weightlifting AAS-users with at least one year cumulative AAS-use (mean 11 ± 7 accumulated years of AAS-use) were compared to 71 non-using weightlifting controls (WLC) using clinical data and echocardiography. RESULTS Sixty-nine were current, 30 former (> 1 year since quitted), and 2 AAS-users were not available for this classification. AAS-users had higher left ventricular mass index (LVMI) (106 ± 26 versus 80 ± 15 g/m2, P < 0.001), worse LV ejection fraction (LVEF) (49 ± 7 versus 59 ± 5%, P < 0.001) and right ventricular global longitudinal strain (RVGLS) (-17.3 ± 3.5 versus -22.8 ± 2.0%, P < 0.001), and higher systolic blood pressure (SBP) (141 ± 17 vs. 133 ± 11 mmHg, p < 0.001) compared with WLC. In current users accumulated duration of AAS-use was 12 ± 7 years, and in former 9 ± 6 years (quitted 6 ± 6 years earlier). Compared to WLC, LVMI and LVEF were pathological in current and former users (p < 0.05) with equal distribution of severely reduced myocardial function (LVEF ≤40%) (11% vs. 10%, NS). In current users estimated life time AAS-dose correlated with reduced LVEF and LVGLS, p < 0.05, but not with LVMI, p = 0.12. Regression analyses of the total population showed that the strongest determinant of reduced LVEF were not coexisting strength training or hypertension, but history of AAS-use (β -0.53, P < 0.001). CONCLUSIONS Long-term AAS-users showed severely biventricular cardiomyopathy. The reduced systolic function was also found upon discountied use.

Abstract
The role of the beta-adrenergic signaling pathway in heart failure (HF) is pivotal. Early blockade of this pathway with beta-blocker (BB) therapy is recommended as the first-line medication for patients with HF and reduced ejection fraction (HFrEF). Conversely, in patients with severe acute HF (AHF), including those with resolved cardiogenic shock (CS), BB initiation can be hazardous. There are very few data on the management of BB in these situations. The present expert consensus aims to review all published data on the use of BB in patients with severe decompensated AHF, with or without hemodynamic compromise, and proposes an expert-recommended practical algorithm for the prescription and monitoring of BB therapy in critical settings.

Abstract
BACKGROUND There is a paucity of data on the burden of heart failure (HF) in Central Australia, the most populous Indigenous region in the country. AIMS To characterize Indigenous and non-Indigenous Australians with HF in Central Australia. METHODS Consecutive patients with HF and reduced ejection fraction <50% were included for the period 2019 to 2021. Clinical, echocardiographic and major adverse cardiovascular events (MACE) data were collected. RESULTS Four hundred twenty-four patients with HF were included (70% Indigenous, 59% male; follow-up 2.2 ± 0.5 years). Indigenous Australians were younger (53 ± 15 vs 68 ± 13 years, P < 0.001) with higher rates of rheumatic heart disease (18% vs 1%, P < 0.001), diabetes (63% vs 33%, P < 0.001) and severe chronic kidney disease (CKD; 32% vs 7%, P < 0.001). HF was more prevalent among Indigenous (138 [95% confidence interval (CI), 123-155] per 10 000) compared with non-Indigenous Australians (53 [95% CI, 44-63] per 10 000), particularly among younger individuals and females. There were similar HF aetiologies between groups. Guideline-directed medical therapy (GDMT) was suboptimal and similar between the groups: angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (64% vs 67%, P = 0.47) and β-blockers (68% vs 71%, P = 0.47). Indigenous Australians had a significantly higher rate of MACE (54% vs 28%, P < 0.001) and death from any cause (24% vs 13%, P = 0.013). CONCLUSIONS HF is more than two times as prevalent among Indigenous Central Australians, particularly among younger individuals and females. Despite similar HF aetiologies and GDMT, MACE and mortality outcomes are higher in Indigenous individuals with HF. These data have implications for efforts to close the Indigenous gap in morbidity and mortality.

Abstract
There exists a paucity of research data reported by analyses performed on randomized clinical trials (RCTs) that encompass quality of life (QOL) and the aftermath for patients suffering from heart failure with reduced ejection fraction (HFrEF). This systematic review and meta-analysis of randomized clinical trials (RCTs) have been done to evaluate the drug sacubitril/valsartan in the treatment of heart failure (HF) with reduced ejection fraction (HFrEF) with a clear focus on the effect it bestows on measures of physical exercise tolerance and quality of life. A thorough systematic search was done in databases including Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov, Embase, and PubMed from 1 January 2010 to 1 January 2023. The search only included published RCTs on adult patients aged 18 and above, with heart failure with reduced ejection fraction (HFrEF). Data analysis was performed by using the software RevMan 5.4 (Cochrane Collaboration, London, United Kingdom). The included studies' bias risk was assessed using the Cochrane Collaboration's Risk of Bias tool. The quality of evidence for the primary outcome was done using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. This systematic review and meta-analysis of RCTs yielded 458 studies, of which eight randomized clinical trials were included and analyzed. The meta-analysis of the included trials shows that the I2 value is 61% (i.e., I2 > 50%), demonstrating a substantial heterogeneity within the studies. The left ventricular ejection fraction (LVEF) expressed in percentage was reported in the five studies, and thereby, a subgroup analysis that yielded a confidence interval (CI) of 95% had the standard mean difference of 0.02 (-0.02, 0.07). The trials had disparity between the reporting of effect on peak oxygen consumption (VO2), measured through cardiopulmonary exercise testing (CPET) methods, six-minute walking test (6MWT), overall physical activity, and exercise capacity. Sacubitril/valsartan did not exponentially improve peak VO2 or 6MWT in these trials; however, the patient-reported data suggested that the quality of life was modestly influenced by the drug. A subgroup analysis was performed using the pooled effect value by the random effects model. The findings showed that the sacubitril/valsartan group significantly was better than the control group in improving HFrEF-associated health-related quality of life (HRQoL). This study is a systematic review and meta-analysis of randomized clinical trials that evaluated the drug sacubitril/valsartan in treating heart failure with reduced ejection fraction (HFrEF) and focused on its tangible effect on the measures of physical exercise tolerance and quality of life. It depicts that the statistical scrutiny due to the lack of significant data and parity across studies did not impart significant improvement of either LVEF, peak VO2, or 6MWT with the use of sacubitril/valsartan; however, the reported exercise tolerance, including daytime physical activity, had a modest impact with the said drug. The pooled values demonstrated that the sacubitril/valsartan group significantly outperformed the control group in improving HFrEF HRQoL.

Abstract
AIMS The aim of this study was to investigate the prognostic utility of left ventricular (LV) global longitudinal strain (LV-GLS) in patients with hypertrophic cardiomyopathy (HCM) and an LV ejection fraction (LVEF) of 50-60%. METHODS AND RESULTS This retrospective cohort study included 349 patients with HCM and an LVEF of 50-60%. The primary outcome was a composite of cardiovascular death, including sudden cardiac death (SCD) and SCD-equivalent events. The secondary outcomes were SCD/SCD-equivalent events, cardiovascular death (including SCD), and all-cause death. The final analysis included 349 patients (mean age 59.2 ± 14.2 years, men 75.6%). During a median follow-up of 4.1 years, the primary outcome occurred in 26 (7.4%), while the secondary outcomes of SCD/SCD-equivalent events, cardiovascular death, and all-cause death occurred in 15 (4.2%), 20 (5.7%), and 34 (9.7%), respectively. After adjusting for age, atrial fibrillation, ischaemic stroke, LVEF, and left atrial volume index, absolute LV-GLS (%) was independently associated with the primary outcome [adjusted hazard ratio (HR) 0.88, 95% confidence interval (CI) 0.788-0.988, P = 0.029]. According to receiver operating characteristic analysis, 10.5% is an optimal cut-off value for absolute LV-GLS in predicting the primary outcome. Patients with an absolute LV-GLS ≤ 10.5% had a higher risk of the primary outcome than those with an absolute LV-GLS > 10.5% (adjusted HR 2.54, 95% CI 1.117-5.787, P = 0.026). Absolute LV-GLS ≤ 10.5% was an independent predictor for each secondary outcome (P < 0.05). CONCLUSIONS LV-GLS was an independent predictor of a composite of cardiovascular death, including SCD/SCD-equivalent events, in patients with HCM and an LVEF of 50-60%. Therefore, LV-GLS can help in risk stratification in these patients.

Abstract
AIMS Left ventricular systolic dysfunction (LSVD) is a heterogeneous condition with several factors influencing prognosis. Better phenotyping of asymptomatic individuals can inform preventative strategies. This study aims to explore the clinical phenotypes of LVSD in initially asymptomatic subjects and their association with clinical outcomes and cardiovascular abnormalities through multi-dimensional data clustering. METHODS AND RESULTS Clustering analysis was performed on 60 clinically available variables from 1563 UK Biobank participants without pre-existing heart failure (HF) and with left ventricular ejection fraction (LVEF) < 50% on cardiovascular magnetic resonance (CMR) assessment. Risks of developing HF, other cardiovascular events, death, and a composite of major adverse cardiovascular events (MACE) associated with clusters were investigated. Cardiovascular imaging characteristics, not included in the clustering analysis, were also evaluated. Three distinct clusters were identified, differing considerably in lifestyle habits, cardiovascular risk factors, electrocardiographic parameters, and cardiometabolic profiles. A stepwise increase in risk profile was observed from Cluster 1 to Cluster 3, independent of traditional risk factors and LVEF. Compared with Cluster 1, the lowest risk subset, the risk of MACE ranged from 1.42 [95% confidence interval (CI): 1.03-1.96; P < 0.05] for Cluster 2 to 1.72 (95% CI: 1.36-2.35; P < 0.001) for Cluster 3. Cluster 3, the highest risk profile, had features of adverse cardiovascular imaging with the greatest LV re-modelling, myocardial dysfunction, and decrease in arterial compliance. CONCLUSIONS Clustering of clinical variables identified three distinct risk profiles and clinical trajectories of LVSD amongst initially asymptomatic subjects. Improved characterization may facilitate tailored interventions based on the LVSD sub-type and improve clinical outcomes.

Abstract
Background Coronavirus disease 2019 (COVID-19) has a great impact on both, physical and psychological wellbeing. The COVID-19 pandemic promoted increasing digitalization of the work environment and social isolation. This psychosocial stress in turn can induce physical distress with clinical manifestation. So can the changed work and social environment in the COVID-19 pandemic trigger acute cardiovascular disease? Case Description Here, we present a case of a 56-year-old postmenopausal woman suffering from Takotsubo cardiomyopathy (TTC) evoked by emotional stress during a virtual work meeting. Like many others, our patient was urged to work from home (WFH) in accordance with the contact restrictions due to COVID-19. She presented at our chest pain unit with typical angina pectoris-like symptoms such as chest pain and dyspnea. Laboratory analysis confirmed increased troponin levels and evolving T wave inversion in electrocardiogram. Acute coronary syndrome management was commenced. Coronary angiography and left ventriculography revealed non-obstructive coronary arteries and apical ballooning syndrome. Due to immediate guideline-directed treatment with bisoprolol, ramipril, spironolactone and acetylsalicylic acid the patient's condition improved so that she could be discharged after seven days. During a 3-month follow-up the patient showed a normalized ejection fraction and reported no discomfort anymore. Conclusions The ongoing COVID-19 pandemic has also elucidated the importance of the psychosocial health issues in acute cardiovascular care. Having in mind that the social and work environment recently has changed immensely, thus enforcing social isolation and emotional distress, doctors as well as patients must consider TTC as possible etiology of sudden chest pain.

Abstract
(1) Background: Little is known about how left ventricular systolic dysfunction (LVSD) affects functional and clinical outcomes in acute ischemic stroke (AIS) patients undergoing thrombolysis; (2) Methods: A retrospective observational study conducted between 2006 and 2018 included 937 consecutive AIS patients undergoing thrombolysis. LVSD was defined as left ventricular ejection fraction (LVEF) < 50%. Univariate and multivariate binary logistic regression analysis was performed for demographic characteristics. Ordinal shift regression was used for functional modified Rankin Scale (mRS) outcome at 3 months. Survival analysis of mortality, heart failure (HF) admission, myocardial infarction (MI) and stroke/transient ischemic attack (TIA) was evaluated with a Cox-proportional hazards model; (3) Results: LVSD patients in comparison with LVEF ≥ 50% patients accounted for 190 and 747 patients, respectively. LVSD patients had more comorbidities including diabetes mellitus (100 (52.6%) vs. 280 (37.5%), p < 0.001), atrial fibrillation (69 (36.3%) vs. 212 (28.4%), p = 0.033), ischemic heart disease (130 (68.4%) vs. 145 (19.4%), p < 0.001) and HF (150 (78.9%) vs. 46 (6.2%), p < 0.001). LVSD was associated with worse functional mRS outcomes at 3 months (adjusted OR 1.41, 95% CI 1.03-1.92, p = 0.030). Survival analysis identified LVSD to significantly predict all-cause mortality (adjusted HR [aHR] 3.38, 95% CI 1.74-6.54, p < 0.001), subsequent HF admission (aHR 4.23, 95% CI 2.17-8.26, p < 0.001) and MI (aHR 2.49, 95% CI 1.44-4.32, p = 0.001). LVSD did not predict recurrent stroke/TIA (aHR 1.15, 95% CI 0.77-1.72, p = 0.496); (4) Conclusions: LVSD in AIS patients undergoing thrombolysis was associated with increased all-cause mortality, subsequent HF admission, subsequent MI and poorer functional outcomes, highlighting a need to optimize LVEF.

Abstract
Background Acute ST-elevation myocardial infarction (STEMI) can lead to adverse cardiac remodeling, resulting in left ventricular systolic dysfunction (LVSd) and heart failure. Epigenetic regulators, such as microRNAs, may be involved in the physiopathology of LVSd. Objective This study explored microRNAs in peripheral blood mononuclear cells (PBMC) of post-myocardial infarction patients with LVSd. Methods Post-STEMI patients were grouped as having (LVSd, n = 9) or not LVSd (non-LVSd, n = 16). The expression of 61 microRNAs was analyzed in PBMC by RT-qPCR and the differentially expressed microRNAs were identified. Principal Component Analysis stratified the microRNAs based on the development of dysfunction. Predictive variables of LVSd were investigated through logistic regression analysis. A system biology approach was used to explore the regulatory molecular network of the disease and an enrichment analysis was performed. Results The let-7b-5p (AUC: 0.807; 95% CI: 0.63-0.98; p = 0.013), miR-125a-3p (AUC: 0.800; 95% CI: 0.61-0.99; p = 0.036) and miR-326 (AUC: 0.783; 95% CI: 0.54-1.00; p = 0.028) were upregulated in LVSd (p < 0.05) and discriminated LVSd from non-LVSd. Multivariate logistic regression analysis showed let-7b-5p (OR: 16.00; 95% CI: 1.54-166.05; p = 0.020) and miR-326 (OR: 28.00; 95% CI: 2.42-323.70; p = 0.008) as predictors of LVSd. The enrichment analysis revealed association of the targets of these three microRNAs with immunological response, cell-cell adhesion, and cardiac changes. Conclusion LVSd alters the expression of let-7b-5p, miR-326, and miR-125a-3p in PBMC from post-STEMI, indicating their potential involvement in the cardiac dysfunction physiopathology and highlighting these miRNAs as possible LVSd biomarkers.

Abstract
A 17-year-old boy presented during the COVID-19 pandemic in late 2021 with intractable fevers and hemodynamic instability with early gastrointestinal disturbances, resembling features of the pediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2. Our patient required intensive unit care for persistently worsening signs of cardiac failure; initial admission echocardiography demonstrated severe left ventricular dysfunction with an estimated ejection fraction of 27%. Treatment with intravenous IgG and corticosteroids showed a rapid improvement in symptoms, but further specialist cardiological input was required for heart failure in the coronary care unit. Substantial improvement in cardiac function was shown on echocardiography before discharge, initially to left ventricular ejection fraction (LVEF) 51% two days after the commencement of treatment and then to >55% four days later, and on cardiac MRI. An echocardiogram one month post-discharge was normal, and the patient reported complete resolution of heart failure symptoms by four months in addition to full restoration of functional status.

Abstract
Purpose Amyloid overload and microcirculation impairment are both detrimental to left ventricular (LV) systolic function, while it is not clear which factor dominates LV functional remodeling in patients with cardiac amyloidosis (CA). The purpose of this study was to investigate the major factor of LV systolic dysfunction using cardiac magnetic resonance imaging. Materials and methods Forty CA patients and 20 healthy controls were included in this study. The CA group was divided into two subgroups by the left ventricular ejection fraction (LVEF): patients with reduced LVEF (LVEF < 50%, rLVEF), and patients with preserved LVEF (LVEF ≥ 50%, pLVEF). The scanning sequences included cine, native and post-contrast T1 mapping, rest first-pass perfusion and late gadolinium enhancement. Perfusion and mapping parameters were compared among the three groups. Correlation analysis was performed to evaluate the relationship between LVEF and mapping parameters, as well as the relationship between LVEF and perfusion parameters. Results Remarkably higher native T1 value was observed in the rLVEF patients than the pLVEF patients (1442.2 ± 85.8 ms vs. 1407.0 ± 93.9 ms, adjusted p = 0.001). The pLVEF patients showed significantly lower slope dividing baseline signal intensity (slope%BL; rLVEF vs. pLVEF, 55.1 ± 31.0 vs. 46.2 ± 22.3, adjusted p = 0.001) and a lower maximal signal intensity subtracting baseline signal intensity (MaxSI-BL; rLVEF vs. pLVEF, 43.5 ± 23.9 vs. 37.0 ± 18.6, adjusted p = 0.003) compared to the rLVEF patients. CA patients required more time to reach the maximal signal intensity than the controls did (all adjusted p < 0.01). There was no significant correlation between LVEF and first-pass perfusion parameters, while significant negative correlation was observed between LVEF and native T1 (r = -0.434, p = 0.005) in CA patients. Conclusion Amyloid overload in the myocardial interstitium may be the major factor of LV systolic dysfunction in CA patients, other than microcirculation impairment.

Abstract
Hypertrophic cardiomyopathy (HCM) follows highly variable paradigms and disease-specific patterns of progression towards heart failure, arrhythmias and sudden cardiac death. Therefore, a generalized standard approach, shared with other cardiomyopathies, can be misleading in this setting. A multimodality imaging approach facilitates differential diagnosis of phenocopies and improves clinical and therapeutic management of the disease. However, only a profound knowledge of the progression patterns, including clinical features and imaging data, enables an appropriate use of all these resources in clinical practice. Combinations of various imaging tools and novel techniques of artificial intelligence have a potentially relevant role in diagnosis, clinical management and definition of prognosis. Nonetheless, several barriers persist such as unclear appropriate timing of imaging or universal standardization of measures and normal reference limits. This review provides an overview of the current knowledge on multimodality imaging and potentialities of novel tools, including artificial intelligence, in the management of patients with sarcomeric HCM, highlighting the importance of specific "red alerts" to understand the phenotype-genotype linkage.

Abstract
Objectives This study sought to noninvasively determine myocardial iron levels in HIV-1-infected patients using CMR and explore the association between T2* values and mild left ventricular systolic dysfunction (LVSD). Methods This prospective study was conducted from June 2019 to July 2021. HIV-1-infected adults and healthy controls were consecutively enrolled for CMR exam. CMR exam included the assessment of myocardium iron content (T2*), cardiac function (cine), inflammation (T2), and fibrosis (through extracellular volume fraction [ECV] and late gadolinium enhancement [LGE]) measurements. Mild LVSD is defined as a left ventricular ejection fraction (LVEF) between 40% and 49%. Results Of 47 HIV-1-infected patients enrolled, 12 were diagnosed with mild LVSD (HIV-1+/LEVF+) and 35 were diagnosed with preserved LV function (HIV-1+/LEVF-). Compared with healthy controls, HIV-1-infected patients displayed higher T2*, T1, T2, ECV values and lower global circumferential strain (GCS) and global radial strain (GRS) (all P < 0.05). However, between patients with and without mild LVSD, only the T2* values and ECV (all P <0.05) were different. The association between increased T2* values (>26 ms) and mild LVSD remained significant after adjusting for the established univariate predictors (ECV >32.9%, T1 values >1336 ms) of mild LVSD (odds ratio [OR], 10.153; 95% confidence interval [CI] 1.565-65.878, P = 0.015). Conclusions Myocardial T2* values were elevated in HIV-1-infected patients, supporting the notion that ID was associated with mild LVSD. Our findings highlight the potential for ID in HIV-1-infected patients as an auxiliary biomarker to monitor the course of LVSD.

Abstract
Background Left ventricular systolic dysfunction (LVSD) characterized by a reduced left ventricular ejection fraction (LVEF) is associated with adverse patient outcomes. We aimed to build a deep neural network (DNN)-based model using standard 12-lead electrocardiogram (ECG) to screen for LVSD and stratify patient prognosis. Methods This retrospective chart review study was conducted using data from consecutive adults who underwent ECG examinations at Chang Gung Memorial Hospital in Taiwan between October 2007 and December 2019. DNN models were developed to recognize LVSD, defined as LVEF <40%, using original ECG signals or transformed images from 190,359 patients with paired ECG and echocardiogram within 14 days. The 190,359 patients were divided into a training set of 133,225 and a validation set of 57,134. The accuracy of recognizing LVSD and subsequent mortality predictions were tested using ECGs from 190,316 patients with paired data. Of these 190,316 patients, we further selected 49,564 patients with multiple echocardiographic data to predict LVSD incidence. We additionally used data from 1,194,982 patients who underwent ECG only to assess mortality prognostication. External validation was performed using data of 91,425 patients from Tri-Service General Hospital, Taiwan. Results The mean age of patients in the testing dataset was 63.7 ± 16.3 years (46.3% women), and 8,216 patients (4.3%) had LVSD. The median follow-up period was 3.9 years (interquartile range 1.5-7.9 years). The area under the receiver-operating characteristic curve (AUROC), sensitivity, and specificity of the signal-based DNN (DNN-signal) to identify LVSD were 0.95, 0.91, and 0.86, respectively. DNN signal-predicted LVSD was associated with age- and sex-adjusted hazard ratios (HRs) of 2.57 (95% confidence interval [CI], 2.53-2.62) for all-cause mortality and 6.09 (5.83-6.37) for cardiovascular mortality. In patients with multiple echocardiograms, a positive DNN prediction in patients with preserved LVEF was associated with an adjusted HR (95% CI) of 8.33 (7.71 to 9.00) for incident LVSD. Signal- and image-based DNNs performed equally well in the primary and additional datasets. Conclusion Using DNNs, ECG becomes a low-cost, clinically feasible tool to screen LVSD and facilitate accurate prognostication.

Abstract
Coronary artery disease (CAD) remains the most common cause of heart failure with reduced ejection fraction; despite its prevalence, there is limited evidence to guide physicians in managing patients with CAD with percutaneous revascularization. The REVIVED-BCIS2 trial (ClinicalTrials.gov identifier: NCT01920048) represents the first randomized trial to assess the value of percutaneous coronary intervention in addition to optimal medical therapy in patients with ischaemic left ventricular systolic dysfunction and stable CAD. In this article, we review the results of the REVIVED-BCIS2 trial and compare them to the ClinicalTrials.gov Identifier: NCT00023595 trial (ClinicalTrials.gov Identifier: NCT00023595), which investigated the benefit of surgical revascularization on such patients. Finally, we suggest a pathway for physicians managing patients with ischaemic left ventricular systolic dysfunction based on the current evidence and highlight potential avenues for future research.

Abstract
BACKGROUND Whether the association between pulse pressure (PP) and mortality varies with systolic blood pressure (SBP) in ischaemic heart failure (HF) with left ventricular systolic dysfunction (LVSD) is unknown. OBJECTIVE To evaluate the association between PP and all-cause mortality in ischaemic HF patients with SBP status at admission. PATIENTS AND METHODS This prospective cohort study included 1581 ischaemic HF patients with LVSD. A total of 23.3% (n = 368) and 22.2% (n = 351) of the participants had SBP <110 mmHg and SBP >140 mmHg, respectively, with more than 80% of participants being male. Restricted cubic spline was performed to determine whether a nonlinear relationship existed between PP and all-cause mortality risk. A multivariable Cox proportional hazards model was used to assess the association between PP and all-cause mortality. RESULTS After a median of follow-up of 3.0 years, 257 events (16.4%) were observed in the cohort. There was a J-shaped relationship between PP and all-cause mortality (P value for nonlinearity = 0.020), with a risk nadir of approximately 46-49 mmHg. All-cause mortality risk varied with SBP status. Higher PP was associated with worse prognosis when the SBP was ≥110 mmHg, whereas the relationship did not reach statistical significance when the SBP was <110 mmHg. CONCLUSION A J-shaped relationship between PP and all-cause mortality was observed in ischaemic HF patients with LVSD, and higher PP was associated with worse prognosis only in those with SBP ≥110 mmHg. Further studies are needed to corroborate these findings.KEY MESSAGESA J-shaped relationship between pulse pressure and all-cause mortality was observed in ischaemic heart failure patients with left ventricular systolic dysfunction, with a risk nadir of approximately 46-49 mmHg.All-cause mortality risk varied with systolic blood pressure status, and higher pulse pressure was associated with worse prognosis when systolic blood pressure was above 110 mmHg.

Abstract
Catecholaminergic polymorphic ventricular tachycardia (CPVT) can cause fatal tachyarrhythmias brought on by physical or emotional stress. Previously published cases deny the association between CPVT with dilated cardiomyopathy (DCM). However, rare cases show a possible association between CPVT and DCM development. Our case is one of them; we describe the development of dilated cardiomyopathy in a young woman who, six years earlier, went through bilateral cardiac sympathetic denervation (CSD) because of symptomatic catecholaminergic polymorphic ventricular tachycardia.

Abstract
AIM To study the clinical profile and outcomes in children with multisystem inflammatory syndrome in children (MIS-C). METHODS Children aged 1 month to 15 years presenting with MIS-C (May 2020 to November 2021) were enrolled. Clinical, laboratory, echocardiography parameters and outcomes were analysed. RESULTS Eighty-one children (median age 60 months (24-100)) were enrolled. Median duration of fever was 5 days (3-7). Twenty-nine (35.8%) had shock (severe MIS-C) including 23 (28.3%) requiring inotropes (median duration = 25 h (7.5-33)). Ten required mechanical ventilation, 12 had acute kidney injury and 1 child died. Left ventricular (LV) dysfunction was seen in 38 (46.9%), 16 (19.7%) had coronary artery abnormalities (CAA) and 13 (20%) had macrophage activation syndrome. Sixty-one (75.3%) were SARS CoV-2 positive (10 by RT-PCR and 51 by serology). Sixty-eight (83.9%) received immunomodulators. Younger age was significantly associated with CAA (P value = 0.05). Older age, LV dysfunction, SARS CoV-2 positivity, low platelet count and elevated serum ferritin were significantly associated with severe MIS-C (univariate analysis). Younger age was an independent predictor of CAA (P = 0.05); older age (P = 0.043) and low platelet count (P = 0.032) were independent predictors of severe MIS-C (multivariate logistic regression analysis). CONCLUSION Our patients had diverse clinical manifestations with a good outcome. Younger age was significantly associated with CAA. Older age, LV dysfunction, low platelet count and elevated serum ferritin were significantly associated with severe MIS-C. Younger age is an independent predictor of CAA. Older age and low platelet count are independent predictors of severe MIS-C.

Abstract
Background and Aims Left ventricular (LV) systolic dysfunction is a common cause of hemodynamic disturbance perioperatively and is associated with increased morbidity and mortality. Echocardiographic evaluation of left ventricular systolic function (LVSF) has great clinical utility. This study was aimed to test the hypothesis that LVSF assessed by an anesthetist using mitral valve E Point Septal Separation (EPSS) has a significant correlation with that assessed using modified Simpson's method perioperatively. Methods This prospective observational study included 100 patients scheduled for elective surgeries. Transthoracic echocardiography (TTE) was performed preoperatively within 24 hours of surgery by an anesthetist as per American Society of Echocardiography (ASE) guidelines. EPSS measurements were obtained in parasternal long-axis view while volumetric assessment of LV ejection fraction (EF) used apical four-chamber view. Bivariate analysis of EPSS and LV EF was done by testing Pearson correlation coefficient. Receiver Operating Characteristic (ROC) curve constructed to obtain area under curve (AUC) and Youden's Index. Results The mean value of mitral valve EPSS was 7.18 ± 3.95 mm. The calculated mean LV EF value using volumetric analysis was 56.31 ± 11.92%. LV dysfunction as per ASE guidelines is present in 28% of patients. EPSS was statistically significantly related to LV EF negatively with a Pearson coefficient of -0.74 (P < 0.0001). AUC of ROC curve 0.950 (P < 0.0001) suggesting a statistically significant correlation between EPSS and LV EF. Youden's index of EPSS value 7 mm was obtained to predict LV systolic dysfunction. Conclusion Mitral valve EPSS shows a significant negative correlation with gold standard LVEF measurement for LVSF estimation. It can very well be used to assess LVSF perioperatively by anesthetists with brief training.

Abstract
BACKGROUND Although the prevalence and prognostic implications of left ventricular systolic dysfunction (LVSD), and the effect of cardiac therapies on LVSD are well described in patients with acquired heart disease, such data are sparse in adults with congenital heart disease (CHD). OBJECTIVES The purpose of this study was to determine the prevalence, risk factors, and prognostic implications of LVSD, and the effect of cardiac therapies (guideline-directed medical therapy [GDMT] and cardiac resynchronization therapy [CRT]) on LVSD in adults with CHD. METHODS This was a retrospective study of adults with CHD with systemic LV (2003-2019). LVSD was defined as left ventricular ejection fraction (LVEF) <52%/<54% (men/women). Cardiovascular event was defined as heart failure hospitalization, heart transplant, and cardiovascular death. RESULTS Of 4,358 patients, 554 (12%) had LVSD, and the prevalence of LVSD was higher in right-sided lesions compared with left-sided lesions (15% vs 10%; P < 0.001). Cardiovascular events occurred in 312 (7%) patients. LVEF was independently associated with cardiovascular events (HR: 0.95; 95% CI: 0.93-0.97; P = 0.009). Of 544 patients with LVSD, 311 received GDMT and 48 patients received CRT. LVEF increased by 6% (95% CI: 2%-10%) and 11% (95% CI: 8%-14%), and N-terminal pro-hormone brain natriuretic peptide decreased by 151 pg/mL (95% CI: 62-289 pg/mL) and 201 pg/mL (95% CI: 119-321 pg/mL) in patients who received GDMT and CRT, respectively. CONCLUSIONS LVSD was present in 12% of adults with CHD, was more common in patients with right-sided lesions, and was associated with cardiovascular events. GDMT and CRT were associated with improvement in LVEF. These results provide a foundation for clinical trials to rigorously test the benefits of these therapies in CHD patients.

Abstract
Rapidly accelerated fibrosarcoma B-type (BRAF) and mitogen-activated extracellular signal-regulated kinase (MEK) inhibitors have revolutionized melanoma treatment. Approximately half of patients with melanoma harbor a BRAF gene mutation with subsequent dysregulation of the RAF-MEK-ERK signaling pathway. Targeting this pathway with BRAF and MEK blockade results in control of cell proliferation and, in most cases, disease control. These pathways also have cardioprotective effects and are necessary for normal vascular and cardiac physiology. BRAF and MEK inhibitors are associated with adverse cardiovascular effects including hypertension, left ventricular dysfunction, venous thromboembolism, atrial arrhythmia, and electrocardiographic QT interval prolongation. These effects may be underestimated in clinical trials. Baseline cardiovascular assessment and follow-up, including serial imaging and blood pressure assessment, are essential to balance optimal anti-cancer therapy while minimizing cardiovascular side effects. In this review, an overview of BRAF/MEK inhibitor-induced cardiovascular toxicity, the mechanisms underlying these, and strategies for surveillance, prevention, and treatment of these effects are provided.

Abstract
BACKGROUND Assessment of left ventricular systolic dysfunction provides essential information related to the prognosis and management of cardiovascular diseases. The aim of this study is to develop a deep-learning model (DLM) to identify LVEF≤35% via chest X-ray (CXR-EF≤35%) features and investigate the performance and clinical implications. METHODS This study collected 90,547 CXRs with the corresponding LVEF by transthoracic echocardiogram from the outpatient department in an academic medical center. Among these, 77,227 CXRs were used to develop a CXR-EF≤35%. Another 13,320 CXRs were used to validate the performance, which was evaluated by the area under the receiver operating characteristic curve (AUC). Furthermore, CXR-EF≤35% was tested to assess the long-term risks of developing LVEF≤35% and cardiovascular outcomes, which were evaluated by Kaplan-Meier survival analysis and the Cox proportional hazards model. RESULTS The AUCs of CXR-EF≤35% for the detection of LVEF≤35% were 0.888 and 0.867 in internal and external validation cohort. Patients with baseline LVEF>50%, detected as LVEF≤35% by CXR-EF≤35% were at higher risk of long-term developing LVEF≤35% (HRi:3.91, 95% CI, 2.98-5.14; HRe:2.49, 95%CI, 1.89-3.27). Furthermore, patients detected as LVEF≤35% by CXR-EF≤35% had significantly higher future risks of all-cause mortality (HRi:1.40, 95%CI, 1.15-1.71; HRe:1.38, 95%CI, 1.15-1.66), cardiovascular mortality (HRi:3.02, 95%CI, 1.84-4.98; HRe:2.60, 95%CI, 1.77-3.82), and new-onset atrial fibrillation (HRi:2.81, 95%CI, 2.15-3.66; HRe:2.93, 95%CI, 2.34-3.67) compared to those detected as no LVEF≤35%. CONCLUSION CXR-EF≤35% may serve as a screening tool for early detecting LVEF≤35% and independently contribute to predictions of long-term developing LVEF≤35% and cardiovascular outcomes. Further prospective studies are needed to confirm the model performance.

Abstract
The increasing incidence of stress-induced cardiomyopathy is due to the complexities of our modern-day lives, which constantly elicit stress responses. Herein, we aimed to explore the therapeutic potential of Amlexanox and Forskolin in promoting the recovery from stress-induced cardiomyopathy. Isoproterenol-induced cardiomyopathy (ICM) models were made, and the following treatment interventions were administered: 5% v/v DMSO as a placebo, Amlexanox (2.5 mg/100 g/day) treatment, Forskolin (0.5 mg/100 g/day), and Amlexanox and Forskolin combination, at their respective aforementioned dosages. The effects of Amlexanox and Forskolin treatment on ICM models were assessed by eletrocardiography and echocardiography. Also, using histological analysis and ELISA, their impact on myocardial architecture and inflammation were ascertained. ICM mice had excessive myocardial fibrosis, hypertrophy, and aggravated LVSDs which were accompanied by massive CD86+ inflammatory cells infiltration. Amlexanox treatment attenuated the myocardial hypertrophy, fibrosis, and inflammation and also slightly improved systolic functions. Meanwhile, forskolin treatment resulted in arrhythmias but significantly enhanced the resolution of myocardial fibrosis and inflammation. Intriguingly, Amlexanox and Forskolin combination demonstrated the most potency at promoting the recovery of the ICM from LVSD by attenuating maladaptive myocardial hypertrophy, fibrosis, and inflammatory responses. Our findings highlight the Amlexanox and Forskolin combination as a potential therapeutic intervention for enhancing cardiac function recovery from stress-induced cardiomyopathy by promoting the resolution of maladaptive cardiac remodeling.

Abstract
OBJECTIVE To assess the performance of ten electrocardiographic (ECG) parameters regarding the prediction of left ventricular systolic dysfunction (LVSD) after a first ST-segment-elevation myocardial infarction (STEMI). METHODS We analyzed 249 patients (74.7% males) treated with primary percutaneous coronary intervention (PCI) included into a single-center cohort study. We sought associations between baseline and post-PCI ECG parameters and the presence of LVSD (defined as left ventricular ejection fraction [LVEF] ≤ 40% on echocardiography) 6 months after STEMI. RESULTS Patients presenting with LVSD (n = 52) had significantly higher values of heart rate, number of leads with ST-segment elevation and pathological Q-waves, as well as total and maximal ST-segment elevation at baseline and directly after PCI compared with patients without LVSD. They also showed a significantly higher prevalence of anterior STEMI and considerably wider QRS complex after PCI, while QRS duration measurement at baseline showed no significant difference. Additionally, patients presenting with LVSD after 6 months showed markedly more severe ischemia on admission, as assessed with the Sclarovsky-Birnbaum ischemia score, smaller reciprocal ST-segment depression at baseline and less profound ST-segment resolution post PCI. In multivariate regression analysis adjusted for demographic, clinical, biochemical and angiographic variables, anterior location of STEMI (OR 17.78; 95% CI 6.45-48.96; p < 0.001), post-PCI QRS duration (OR 1.56; 95% CI 1.22-2.00; p < 0.001) expressed per increments of 10 ms and impaired post-PCI flow in the infarct-related artery (IRA; TIMI 3 vs. <3; OR 0.14; 95% CI 0.04-0.46; p = 0.001) were identified as independent predictors of LVSD (Nagelkerke's pseudo R2 for the logistic regression model = 0.462). Similarly, in multiple regression analysis, anterior location of STEMI, wider post-PCI QRS, higher baseline number of pathological Q-waves and a higher baseline Sclarovsky-Birnbaum ischemia score, together with impaired post-PCI flow in the IRA, higher values of body mass index and glucose concentration on admission were independently associated with lower values of LVEF at 6 months (corrected R2 = 0.448; p < 0.00001). CONCLUSIONS According to our study, baseline and post-PCI ECG parameters are of modest value for the prediction of LVSD occurrence 6 months after a first STEMI.

Abstract
Background: The relation between left anterior descending artery (LAD) anatomy and clinical outcomes in patients with anterior ST-segment elevation myocardial infarction (STEMI) has not been fully investigated. The aim of this study was to determine the frequency and severity of short-term cardiovascular outcomes in patients with Anterior ST-Segment Elevation Myocardial Infarction (STEMI) undergoing primary percutaneous intervention (PCI), based on wraparound and non-wraparound left anterior descending artery (LAD). Methods: In a cross-sectional study, 126 patients with anterior STEMI who were admitted to Shahid Chamran Hospital in Isfahan during 2020 were studied. Patients were evaluated for anatomical features of LAD coronary artery and clinical outcomes determined and compared based on wraparound LAD and non-wraparound LAD during hospitalization and up to one month after PCI. Results: The prevalence of wraparound LAD in the studied patients was 73% and left ventricular systolic dysfunction in admission was greater and more severe in patients with wraparound LADs compared with those with non-wraparound. Severe LV systolic dysfunction in the wraparound and non-wraparound groups was 39.6% and 8.8%, respectively (P < 0.001). Also, the frequency of arrhythmias in the wraparound group (21.7%) was higher than the non-wraparound group (5.9%) (P = 0.037). Conclusion: The patients with anterior STEMI and wraparound LAD have a worse clinical outcome and more severe left ventricular systolic dysfunction. Therefore, it seems that the study of the anatomical condition of the LAD artery at the time of angiography is of great importance in the way of observation and care, and treatment of patients.

Abstract
Aim: To investigate the relationship between post-myocardial infarction (MI) left ventricular ejection fraction (LVEF) and fibrosis marker HE-4 in primarily revascularized patients with ST-segment elevation MI (STEMI). Patients & methods: In 94 consecutive STEMI patients (median age 57 [IQR: 50-69] years; 77.7% male), HE-4 values were measured at hospital admission and 4 days after STEMI. Transthoracic echocardiography was performed 4 days after STEMI (median 5 days [interquartile range: 4-6]). Results: HE-4 levels 4 days after STEMI were significantly higher in the low ejection fraction group (30.1 [26.0-46.5] pmol/l vs 48.5 [32.5-85.9] pmol/l, p = 0.004). In the multivariable analysis, HE-4 values (odds ratio: 1.029, 95% CI: 1.012-1.046, p = 0.001), troponin I levels, anterior MI and diabetes mellitus were independent predictors of low LVEF after STEMI. A negative correlation existed between ΔHE-4 levels and LVEF (r: -0.337, p = 0.001). Receiver operating characteristic analysis indicated 34.01 pmol/l HE-4 at 4 days after STEMI identified patients with low LVEF (AUC = 0.707; 95% CI: 0.601-0.813; p = 0.001). Conclusion: In revascularized STEMI patients, high HE-4 levels are associated with decreased LVEF. HE-4 may represent a diagnostic marker and treatment target for patients with heart failure or left ventricular systolic dysfunction after STEMI.

Abstract
OBJECTIVE To validate an artificial intelligence-augmented electrocardiogram (AI-ECG) algorithm for the detection of preclinical left ventricular systolic dysfunction (LVSD) in a large community-based cohort. METHODS We identified a randomly selected community-based cohort of 2041 subjects age 45 years or older in Olmsted County, Minnesota. All participants underwent a study echocardiogram and ECG. We first assessed the performance of the AI-ECG to identify LVSD (ejection fraction ≤40%). After excluding participants with clinical heart failure, we further assessed the AI-ECG to detect preclinical LVSD among all patients (n=1996) and in a high-risk subgroup (n=1348). Next we modelled an imputed screening program for preclinical LVSD detection where a positive AI-ECG triggered an echocardiogram. Finally, we assessed the ability of the AI-ECG to predict future LVSD. Participants were enrolled between January 1, 1997, and September 30, 2000; and LVSD surveillance was performed for 10 years after enrollment. RESULTS For detection of LVSD in the total population (prevalence, 2.0%), the area under the receiver operating curve for AI-ECG was 0.97 (sensitivity, 90%; specificity, 92%); in the high-risk subgroup (prevalence 2.7%), the area under the curve was 0.97 (sensitivity, 92%; specificity, 93%). In an imputed screening program, identification of one preclinical LSVD case would require 88.3 AI-ECGs and 8.7 echocardiograms in the total population and 65.7 AI-ECGs and 5.5 echocardiograms in the high-risk subgroup. The unadjusted hazard ratio for a positive AI-ECG for incident LVSD over 10 years was 2.31 (95% CI, 1.32 to 4.05; P=.004). CONCLUSION Artificial intelligence-augmented ECG can identify preclinical LVSD in the community and warrants further study as a screening tool for preclinical LVSD.

Abstract
Takotsubo cardiomyopathy (TCM) is a cardiac condition that presents with features of acute myocardial infarction and transient systolic dysfunction without angiographic findings of obstructive coronary heart disease. Common presenting symptoms include acute substernal chest pain, dyspnea and syncope. It is usually triggered by recent emotional or physical stress such as head trauma, stroke, sepsis, overproduction of catecholamines such as pheochromocytoma or following Myasthenia crisis. We are here to report a case of TCM who does not have any identifiable emotional or physical stress prior to the event. The patient was a 76-year-old Caucasian female with a past medical history of hypertension who presented to the hospital with chest pain which initially was treated as non-ST elevation myocardial infarction (NSTEMI) with aspirin, ticagrelor and heparin infusion. Cardiac catheterization later revealed non-obstructive coronary artery disease but showed akinesis of inferior, apical and anterior walls with hyperdynamic basal segments indicating TCM.

Abstract
Acute cerebral injuries are often accompanied by sudden electrocardiogram (ECG) changes such as cardiac arrhythmias, QT prolongation, and abnormal T-wave morphology. One rare phenomenon is “cerebral T-waves”, which are T-waves observed in the context of stroke and described as transient, symmetric, and deeply inverted. The classic cerebral T wave is defined as a T-wave inversion of ≥5 mm depth in at least four contiguous precordial leads, and it is more commonly observed in the setting of acute ischemic stroke rather than hemorrhagic stroke. We describe the case of a patient who initially presented with acute pulmonary edema, T-wave inversions in the precordial leads, and left ventricular dysfunction on echocardiogram raising suspicion of an ischemic cardiac event. However, a brain CT scan performed on the third day of admission proved us wrong.

Abstract
Background: Neprilysin inhibition has demonstrated impressive benefits in heart failure treatment, and is the current focus of interest in cardiovascular (CV) and kidney diseases. However, the role of circulating neprilysin as a biomarker for CV events is unclear in hemodialysis (HD) patients. Methods: A total of 439 HD patients from the K-cohort were enrolled from June 2016 to April 2019. The plasma neprilysin level and echocardiographic findings at baseline were examined. The patients were prospectively followed up to assess the primary endpoint (composite of CV events and cardiac events). Results: Plasma neprilysin level was positively correlated with left ventricular (LV) mass index, LV end-systolic volume, and LV end-diastolic volume. Multivariate linear regression analysis revealed that neprilysin level was negatively correlated with LV ejection fraction (β = −2.14; p = 0.013). The cumulative event rate of the composite of CV events was significantly greater in neprilysin tertile 3 (p = 0.049). Neprilysin tertile 3 was also associated with an increased cumulative event rate of cardiac events (p = 0.016). In Cox regression analysis, neprilysin tertile 3 was associated with a 2.61-fold risk for the composite of CV events [95% confidence interval (CI), 1.37–4.97] and a 2.72-fold risk for cardiac events (95% CI, 1.33–5.56) after adjustment for multiple variables. Conclusions: Higher circulating neprilysin levels independently predicted the composite of CV events and cardiac events in HD patients. The results of this study suggest the importance of future studies on the effect of neprilysin inhibition in reducing CV events.

Abstract
Background Post-transplant cyclophosphamide (PT-Cy) has become a standard of care in haploidentical hematopoietic stem cell transplantation (HSCT) to reduce the risk of graft-versus-host disease. However, data on cardiac events associated with PT-Cy are scarce. Objectives This study sought to assess the incidence and clinical features of cardiac events associated with PT-Cy. Methods The study compared clinical outcomes between patients who received PT-Cy (n = 136) and patients who did not (n = 195), with a focus on early cardiac events (ECE) occurring within the first 100 days after HSCT. All patients had the same systematic cardiac monitoring. Results The cumulative incidence of ECE was 19% in the PT-Cy group and 6% in the no–PT-Cy group (p < 0.001). The main ECE occurring after PT-Cy were left ventricular systolic dysfunction (13%), acute pulmonary edema (7%), pericarditis (4%), arrhythmia (3%), and acute coronary syndrome (2%). Cardiovascular risk factors were not associated with ECE. In multivariable analysis, the use of PT-Cy was associated with ECE (hazard ratio: 2.7; 95% confidence interval: 1.4 to 4.9; p = 0.002]. Older age, sequential conditioning regimen, and Cy exposure before HSCT were also associated with a higher incidence of ECE. Finally, a history of cardiac events before HSCT and ECE had a detrimental impact on overall survival. Conclusions PT-Cy is associated with a higher incidence of ECE occurring within the first 100 days after HSCT. Patients who have a cardiac event after HSCT have lower overall survival. These results may help to improve the selection of patients who are eligible to undergo HSCT with PT-Cy, especially older adult patients and patients with previous exposure to Cy.

Abstract
Coarctation of the aorta is a leading cause of morbidity and mortality among adults with congenital heart disease (ACHD). Lifelong surveillance is mandatory to screen for possible long-term cardiovascular events. Left ventricular systolic dysfunction has been reported in association with recoarctation, and association with dilated cardiomyopathy (DCMP) is very rare. Herein, we report the case of a 19-year-old boy with coarctation of the aorta who complained of mild exertional dyspnea. Cardiac magnetic resonance revealed a moderately dilated, hypokinetic left ventricle (LV), with mildly reduced EF (45%), and residual isthmic coarctation was excluded. Genetic tests revealed a heterozygous missense variant in TNNT2 (NM_001001430.2): c.518G>A (p. Arg173Gln). This case highlights the role of careful history taking: a family history of cardiomyopathy should not be overlooked even when the clinical setting seems to suggest a predisposition to hemodynamic factors for LVSD.

Abstract
Background: The number of coronary chronic total occlusion (CTO) patients with left ventricular (LV) systolic dysfunction is significant, but the clinical outcomes of these patients are rarely reported. The present retrospective cohort study aimed to investigate the long-term outcomes of successful recanalization vs. optimal medical therapy (MT) for CTOs in patients with preserved and impaired LV systolic function. Methods: A total of 1,895 patients with CTOs were stratified according to LV function. Of these, 1,420 patients (74.9%) with LV ejection fraction (LVEF) >45% and 475 patients (25.1%) with LVEF ≤45% were treated with optimal MT or successful CTO percutaneous coronary intervention (PCI). A 1:1 propensity score matching (PSM) was conducted to reduce the impact of potential confounding on the outcomes. The primary outcome was the frequency of major adverse cardiac events (MACEs). Results: Throughout a 2.6-year follow-up and after adjusting for confounders, among patients with preserved LV function, successful CTO PCI was associated with reduced incidence of MACE (14.2 vs. 23.9%, adjusted HR 0.63, 95% CI 0.48–0.83, p = 0.001) compared to MT. There was no significant difference in MACE occurrence (29.6 vs. 28.9%, adjusted HR 1.05, 95% CI: 0.71–1.56, p = 0.792) between successful recanalization and MT in patients with LV systolic dysfunction. The primary outcome among patients with impaired and preserved LV systolic function after PSM was similar to that from earlier findings before PSM was conducted. A significant interaction between LV function and therapeutic strategy for MACE was observed (interaction p = 0.038). Conclusions: Compared to MT alone for management of patients with CTOs, successful CTO PCI may reduce the risk of MACE in patients with preserved LV systolic function, but not in patients with LV dysfunction.

Abstract
BACKGROUND Obesity is a worldwide epidemic that has been associated with poor outcomes. Previous studies have demonstrated an inverse relationship between body mass index (BMI) and outcomes, the 'obesity paradox', in several diseases. HYPOTHESIS We sought to evaluate whether the obesity paradox is present in patients with left ventricular systolic dysfunction (LVSD) of all etiologies, using all-cause mortality as the primary endpoint and hospitalization as the secondary endpoint. METHODS We conducted a retrospective cohort study of LVSD patients (n = 18 003) seen within the University of Pittsburgh Medical Center network between January 2011 and December 2017. Patients were divided into four BMI categories (underweight, normal weight, overweight, and obese) and stratified by left ventricular ejection fraction (LVEF): <20%, 20-35%, and 35-50%. RESULTS Over a median follow-up of 2.28 years, higher BMI (mean 28.9 ± 6.8) was associated with better survival for the overall cohort and within LVEF strata (p < .0001). The most common cause of hospitalization was subendocardial infarction among underweight and normal weight patients and heart failure among overweight and obese patients. Cox proportional hazards model showed that BMI, age, and comorbid conditions of diabetes mellitus, chronic obstructive pulmonary disease, chronic kidney disease, and prior myocardial infarction are independent predictors of death. CONCLUSIONS Our results support the existence of an obesity paradox impacting all-cause mortality in patients with LVSD of ischemic and non-ischemic etiologies even after adjusting for LVEF and comorbidities. Additional research is needed to understand the effect of weight loss on survival once a diagnosis of LVSD is established.

Abstract
(1) Background: Coronavirus infection (Covid-19) has emerged as a severe medical condition, associated with high pulmonary morbidity and often with cardiovascular (CV) complications. This study aims to evidence the persistence of left ventricular (LV) systolic function (LV-SF) alterations and diastolic dysfunction (DD) in COVID-19 patients without history of cardiovascular (CV) diseases by transthoracic echocardiography (TTE). (2) Methods: 125 patients, aged under 55 years, hospitalized during the first outbreak of Covid-19 for moderate pneumonia, underwent a comprehensive cardiologic examination and TTE at 6-10 weeks after discharge. Their initial in-hospital laboratory data and thorax computer tomography (TCT) were accessed from the electronic database of the hospital. (3) Results: with TTE, we documented alterations of LV-SF and DD in 8.8% of patients and in 16.8% only patterns of DD, statistically correlated with the initial levels of creatin-kinase (CK-MB) and inflammatory factors. Multivariate regression analysis evidenced that CK-MB levels, age, and body mass index (BMI) are responsible for 65% of LV-SF decrease. (4) Conclusions: Alterations of LV-SF and DD are frequent in post-acute COVID-19 infection and are responsible for the persistence of symptoms. Elevated myocardial necrosis markers during the acute phase seem to predict subsequent alteration of cardiac performance.

Abstract
INTRODUCTION Morbid obesity (body mass index > 40 kg/m2) is a risk factor for the development of left ventricular systolic dysfunction (LVSD) and can complicate the management of LVSD. Bariatric surgery is increasingly recognized as a safe and effective way to achieve marked weight loss, but studies on improving LVSD populations are limited. We retrospectively analyzed the first case of the Asia-Pacific region with morbid obesity and left ventricular ejection fraction (LVEF) < 50% who underwent bariatric surgery at our medical center. PATIENT CONCERNS The patient was admitted to the hospital due to progressive weight gain for more than 10 years. The patient used to be in good health. One year before admission, the patient was hospitalized in another hospital due to shortness of breath. After the relevant examination, the patient was diagnosed with dilated cardiomyopathy. DIAGNOSIS The body mass index of the patient was 45.9 kg/m2, and the patient was diagnosed with morbid obesity. He was diagnosed with dilated cardiomyopathy and cardiac function class IV in another hospital. After completing a preoperative examination, the patient was diagnosed with hyperuricemia, hyperlipidemia, fatty liver disease and severe sleep apnea. INTERVENTIONS The patient successfully underwent laparoscopic sleeve gastrectomy plus jejunal bypass. OUTCOMES Six months after the surgery, patient weight lost was 33.6 kg, and the LVEF increased from 31% to 55%. The cardiac function of the patient recovered from class IV to class I, and the patient's hyperuricemia, hyperlipidemia and sleep apnea were significantly improved. CONCLUSION Bariatric surgery may be a safe and effective intervention for morbidly obese patients with LVSD. Bariatric surgery was associated with an improvement in LVEF. However, the specific mechanism still needs further study.

Abstract
INTRODUCTION Left ventricular diastolic dysfunction (LVDD) adversely impacts renal function, and E/e' is a significant predictor of adverse kidney events under different clinical conditions. However, no studies have evaluated the association between LVDD and septic acute kidney injury (AKI) among patients with severe sepsis and septic shock. METHODS This multicenter retrospective study evaluated adult patients with severe sepsis or septic shock between January 1, 2013, and December 31, 2019, who underwent echocardiography within 24 hours after admission to an intensive care unit. RESULTS A total of 495 adult patients were enrolled in the study. LVDD grades II and III were associated with severe (stage 3) AKI (p < 0.001, p for trend < 0.001). E/e' and e' were risk factors for septic AKI (OR, 1.155; 95% CI, 1.088-1.226, p < 0.001; and OR, 7.218; 95% CI, 2.942-17.712, p < 0.001, respectively) in the multivariate logistic regression analysis. The area under the receiver operating characteristic curve of E/e' and e' was 0.728 (95% CI, 0.680-0.777, p < 0.001) and 0.715 (95% CI, 0.665-0.764, p < 0.001), respectively. CONCLUSIONS LVDD was associated with septic AKI, and E/e' and e' are useful predictors of septic AKI among patients with severe sepsis or septic shock. TRIAL REGISTRATION The study was registered at the Chinese Clinical Trial Registry (Protocol No. ChiCTR2000033083).

Abstract
A 22-year-old man presented with severe left ventricular (LV) dysfunction and progressive heart failure. The 12-lead electrocardiogram showed short runs of supraventricular tachycardia suggestive of focal atrial tachycardia. The patient underwent successful radiofrequency ablation. There was a complete recovery of symptoms and LV function at six months of follow-up. We discuss the importance of identifying tachycardiomyopathy as a reversible cause of heart failure.

Abstract
Objective: Left ventricular systolic dysfunction (LVSD) after ST-segment elevation myocardial infarction (STEMI) is associated with poor outcome. Trimethylamine N-oxide (TMAO), a gut metabolite, is linked to cardiovascular diseases but its relationship with LVSD after STEMI remains unclear. The present study therefore aimed to investigate the relationship between TMAO and LVSD at 30 days after a first anterior STEMI. Methods: This was a sub-study from the OCTAMI (Optical Coherence Tomography Examination in Acute Myocardial Infarction) registry. Eligible patients were included in current study if they: (1) presented with a first anterior STEMI; (2) had available baseline TMAO concentration; (3) completed a cardiovascular magnetic resonance examination at 30 days after STEMI. LVSD was defined as left ventricular ejection fraction < 50%. Associations between TMAO and left ventricular ejection fraction, infarct size and left ventricular global strain were examined. Results: In total, 78 patients were included in final analysis. Overall, TMAO was moderately associated with peak cTnI (r = 0.27, p = 0.01), age (r = 0.34, p < 0.01), and estimated glomerular filtration rate (r = −0.30, p < 0.01). At 30-day follow-up, 41 patients were in the LVSD group and 37 in the non-LVSD group. Baseline TMAO levels were not significantly different between the two groups (LVSD vs. non-LVSD: median 1.9 μM, 25−75th percentiles 1.5–3.3 μM vs. median 1.9 μM, 25−75th percentiles 1.5–2.7 μM; p = 0.46). Linear regression analyses showed that TMAO was not associated with left ventricular ejection fraction, infarct size or left ventricular global strain at 30 days (all p > 0.05). Conclusions: TMAO was not significantly correlated with 30-day LVSD in patients with a first anterior STEMI after primary revascularization.

Abstract
BACKGROUND Cushing's disease is a rare condition associated with a high cardiovascular risk and hypercortisolemia-related hemodynamic dysfunction, the extent of which can be assessed with a noninvasive method, called impedance cardiography. The standard methods for hemodynamic assessment, such as echocardiography or ambulatory blood pressure monitoring may be insufficient to fully evaluate patients with Cushing's disease; therefore, impedance cardiography is being currently considered a new modality for assessing early hemodynamic dysfunction in this patient population. The use of impedance cardiography for diagnosis and treatment of Cushing's disease may serve as personalized noninvasive hemodynamic status assessment and provide a better insight into the pathophysiology of Cushing's disease. The purpose of this study was to assess the hemodynamic profile of Cushing's disease patients and compare it with that in the control group. MATERIAL AND METHODS This observational prospective clinical study aimed to compare 54 patients with Cushing's disease (mean age 41 years; with 64.8% of this population affected with arterial hypertension) and a matched 54-person control group (mean age 45 years; with 74.1% of this population affected with arterial hypertension). The hemodynamic parameters assessed with impedance cardiography included the stroke index (SI), cardiac index (CI), systemic vascular resistance index (SVRI), velocity index (VI), (ACI), Heather index (HI), and thoracic fluid content (TFC). RESULTS The Cushing's disease group was characterized by a higher diastolic blood pressure and a younger age than the control group (82.9 vs. 79.1 mmHg, p=0.045; and 41.1 vs. 44.9 years, p=0.035, respectively). Impedance cardiography parameters in the Cushing's disease group showed: lower values of SI (42.1 vs. 52.8 ml/m2; p ≤ 0.0001), CI (2.99 vs. 3.64 l/min/m2; p ≤ 0,0001), VI (42.9 vs. 52.1 1/1000/s; p=0.001), ACI (68.7 vs. 80.5 1/100/s2; p=0,037), HI (13.1 vs. 15.2 Ohm/s2; p=0.033), and TFC (25.5 vs. 27.7 1/kOhm; p=0.006) and a higher SVRI (2,515 vs. 1,893 dyn*s*cm-5*m2; p ≤ 0.0001) than those in the control group. CONCLUSIONS Cushing's disease is associated with significantly greater vasoconstriction and left ventricular systolic dysfunction. An individual assessment with impedance cardiography may be useful in Cushing's disease patients in order to identify subclinical cardiovascular complications of chronic hypercortisolemia as potential therapeutic targets.

Abstract
Alcohol abuse is positively associated with cardiovascular disease. Dietary low-carbohydrate/high-protein (LCHP) intake confers a greater mortality risk. Here, the impact of ethanol consumption in combination with dietary LCHP intake on left ventricular (LV) systolic function and lethal ventricular arrhythmia susceptibility were investigated in apolipoprotein E/low-density lipoprotein receptor double-knockout (AL) mice. The underlying mechanisms, cardiac sympathovagal balance, beta-adrenergic receptor (ADRB) levels, and gap junction channel protein connexin 43 (Cx43) expression, were examined. Male AL mice fed an LCHP diet with or without ethanol were bred for 16 weeks. Age-matched male AL and wild-type mice received standard chow diet and served as controls. The following were used to assess LV systolic function, lethal ventricular arrhythmia susceptibility, cardiac sympathovagal balance, Cx43 expression, and ADRB levels: The results demonstrated that ethanol consumption in combination with dietary LCHP intake worsened LCHP-induced LV systolic dysfunction in AL mice and enhanced their susceptibility in the ventricular arrhythmia-evoked test. There were concomitant increases in LV weight, LF/HF ratio shown by HRV, TH, ADRB1, ADRB2, and Cx43 expressions by LV fluorescence immunohistochemistry, and LV Cx43 messenger ribonucleic acid expression by PCR. In AL mice, alcohol consumption combined with dietary LCHP intake may thus promote a shift in cardiac sympathovagal balance toward sympathetic predominance, the increases in beta-adrenergic receptors (ADRB1 and ADRB2), and then affect the gap junction channel protein Cx43, which in turn could contribute to increased risks of LV systolic dysfunction and susceptibility to lethal ventricular arrhythmia.

Abstract
BACKGROUND Coronary angiography (CA) is usually performed in patients with reduced left ventricular ejection fraction (LVEF) to search ischemic cardiomyopathy. Our aim was to examine the agreement between CA and cardiovascular magnetic resonance (CMR) imaging among a cohort of patients with unexplained reduced LVEF, and estimate what would have been the consequences of using CMR imaging as the first-line examination. METHODS Three hundred five patients with unexplained reduced LVEF of ≤45% who underwent both CA and CMR imaging were retrospectively registered. Patients were classified as CMR+ or CMR- according to presence or absence of myocardial ischemic scar, and classified CA+ or CA- according to presence or absence of significant coronary artery disease. RESULTS CMR+ (n = 89) included all 54 CA+ patients, except 2 with distal coronary artery disease in whom no revascularization was proposed. Among the 247 CA- patients, 15% were CMR+. CMR imaging had 96% sensitivity, 85% specificity, 99% negative predictive value, and 58% positive predictive value for detecting CA+ patients. Revascularization was performed in 6.5% of the patients (all CMR+). Performing CA only for CMR+ patients would have decreased the number of CAs by 71%. CONCLUSIONS In reduced LVEF, performing CA only in CMR+ patients may significantly decrease the number of unnecessary CAs performed, without missing any patients requiring revascularization.
