Abstract
BACKGROUND Functional abnormalities of the ascending aorta (AA) have been mainly reported in young patients who underwent arterial switch operation (ASO) for transposition of the great arteries (TGA). OBJECTIVES To compare systolic, diastolic brachial and central blood pressures (bSBP, bDBP, cSBP, cDBP), aortic biomechanical parameters, and left ventricular (LV) afterload criteria in adult ASO patients with healthy controls and to assess their relationships with LV remodeling and aortic size. MATERIALS AND METHODS Forty-one prospectively enrolled patients (16.8 to 35.8 years) and 41 age- and sex-matched healthy volunteers underwent cardiac MRI to assess LV remodeling with simultaneous brachial BP estimation. After MRI, carotid-femoral tonometry was performed to measure pulse wave velocity (cfPWV), cSBP and cDBP for further calculation of pulse pressure (cPP), AA distensibility (AAD), and AA and LV elastance (AAE, LVE). RESULTS bSBP, bDBP, cSBP,cDBP and cPP were all significantly higher in ASO group than in controls: cSBP (116.5 ± 13.8 vs 106.1 ± 12.0, p < 0.001), cDBP (72.5 ± 6.9 vs 67.1 ± 9.4, p = 0.002), cPP (44.0 ± 12.1 vs 39.1 ± 8.9, p = 0.003) and not related to aortic size. AAD were decreased in ASO patients vs controls (4.70 ± 2.72 vs 6.69 ± 2.16, p < 0.001). LV mass was correlated with bSBP, cSBP, cPP (ρ = 0.48; p < 0.001), while concentric LV remodeling was correlated with AAE (ρ = 0.60, p < 0.001) and LVE (ρ = 0.32, p = 0.04), but not with distensibility. CONCLUSION Even without reaching arterial hypertension, aortic sBP and PP are increased in the adult TGA population after ASO, altering the pulsatile components of afterload and contributing to LV concentric remodeling.

Abstract
Left ventricular remodeling is an adaptive process initially developed in response to acute myocardial infarction (AMI), but it ends up with negative adverse outcomes such as infarcted wall thinning, ventricular dilation, and cardiac dysfunction. A prolonged excessive inflammatory reaction to cardiomyocytes death and necrosis plays the crucial role in the pathophysiological mechanisms. The pharmacological treatment includes nitroglycerine, β-blockers, ACEi/ARBs, SGLT2i, mineralocorticoid receptor antagonists, and some miscellaneous aspects. Stem cells therapy, CD34+ cells transplantation and gene therapy constitute the promissing therapeutic approaches for post AMI cardiac remodeling, thereby enhancing angiogenesis, cardiomyocytes differenciation and left ventricular function on top of inhibiting apoptosis, inflammation, and collagen deposition. All these lead to reduce infarct size, scar formation and myocardial fibrosis.

Abstract
BACKGROUND A minority of patients with hypertrophic cardiomyopathy (HCM) presents advanced heart failure (HF) during their clinical course, in the context of left ventricular (LV) remodeling with reduced LV ejection fraction (LVEF), or of severe diastolic dysfunction without impaired LVEF. Aim of this study was to describe a multicentric end stage (ES) HCM population and analyze clinical course and outcome among its different phenotypes. METHODS Data of all HCM patients from 7 Italian referral centres were retrospectively evaluated. ES was diagnosed in presence of: LVEF <50% (ES-rEF) or NYHA functional class ≥II with severe diastolic dysfunction (ES-pEF). Outcomes were: HCM-related and all-cause mortality; combined arrhythmic events; advanced HF treatments. RESULTS Study population included 331 ES patients; 87% presented ES-rEF and 13% ES-pEF. At ES recognition, patients with ES-pEF were more commonly females, had more frequently NYHA III/IV, atrial fibrillation and greater maximal LV wall thickness. Over a median follow-up of 5.6 years, 83 (25%) patients died, 46 (15%) experienced arrhythmic events and (26%) 85 received advanced HF treatments. Incidence of HCM-related and all-cause mortality, and of combined arrhythmic events did not differ in ES-pEF and ES-rEF patients, but ES-pEF patients were less likely to receive advanced HF treatments. Older age at ES recognition was an independent predictor of increased HCM-related mortality (p = 0.01) and reduced access to advanced HF treatments (p < 0.0001). CONCLUSIONS Two different HCM-ES phenotypes can be recognized, with ES-pEF showing distinctive features at ES recognition and receiving less frequently advanced HF treatments. Older age at ES recognition has a major impact on outcomes.

Abstract
BACKGROUND Left bundle branch block (LBBB) represents a frequently encountered conduction system disorder. Despite its widespread occurrence, a continual dilemma persists regarding its intricate association with underlying cardiomyopathy and its pivotal role in the initiation of dilated cardiomyopathy. The pathologic alterations linked to LBBB-induced cardiomyopathy (LBBB-CM) have remained elusive. OBJECTIVE This study sought to investigate the chronologic dynamics of LBBB to left ventricular dysfunction and the pathologic mechanism of LBBB-CM. METHODS LBBB model was established through main left bundle branch trunk ablation in 14 canines. All LBBB dogs underwent transesophageal echocardiography and electrocardiography before ablation and at 1 month, 3 months, 6 months, and 12 months after LBBB induction. Single-photon emission computed tomography imaging was performed at 12 months. We then harvested the heart from all LBBB dogs and 14 healthy adult dogs as normal controls for anatomic observation, Purkinje fiber staining, histologic staining, and connexin43 protein expression quantitation. RESULTS LBBB induction caused significant fibrotic changes in the endocardium and mid-myocardium. Purkinje fibers exhibited fatty degeneration, vacuolization, and fibrosis along with downregulated connexin43 protein expression. During a 12-month follow-up, left ventricular dysfunction progressively worsened, peaking at the end of the observation period. The association between myocardial dysfunction, hypoperfusion, and fibrosis was observed in the LBBB-afflicted canines. CONCLUSION LBBB may lead to profound myocardial injury beyond its conduction impairment effects. The temporal progression of left ventricular dysfunction and the pathologic alterations observed shed light on the complex relationship between LBBB and cardiomyopathy. These findings offer insights into potential mechanisms and clinical implications of LBBB-CM.

Abstract
Mosaic valve shows higher pressure gradient after aortic valve replacement compared to other same size labeled prostheses in postoperative echocardiogram. The purpose of this study was to evaluate the mid-term echocardiogram findings and long-term clinical outcomes of patients receiving a 19 mm Mosaic. Forty-six aortic stenosis patients receiving 19 mm Mosaic and 112 patients receiving either 19 mm Magna or Inspiris, who underwent mid-term follow-up echocardiogram were included in the study. Mid-term hemodynamic measurements evaluated by trans-thoracic echocardiogram and long-term outcomes were compared. Patients receiving Mosaic were significantly older (Mosaic: 76 ± 5.1 years vs. Magna/Inspiris: 74 ± 5.5 years, p = 0.046) and had smaller body surface area (Mosaic: 1.40 ± 0.114m2 vs. Magna/Inspiris: 1.48 ± 0.143m2, p < 0.001). There were no significant differences in comorbidities and medications. Post-operative echocardiogram performed at 1 week after the surgery showed higher maximum pressure gradient in patients receiving Mosaic (Mosaic: 38 ± 13.5 mmHg vs. Magna/Inspiris: 31 ± 10.7 mmHg, p = 0.002). Furthermore, mid-term echocardiogram follow-up performed at median duration of 53 ± 14.9 months after the surgery continuously showed higher maximum pressure gradient in patients receiving Mosaic (Mosaic: 45 ± 15.6 mmHg vs. Magna/Inspiris: 32 ± 13.0 mmHg, p < 0.001). However, there were no significant difference in changes in left ventricular mass from baseline in both groups. Kaplan-Meyer curve also showed no difference in long-term mortality and major adverse cardiac and cerebrovascular event between the two groups. Although the pressure gradient across the valve evaluated by echocardiogram was higher in 19 mm Mosaic compared to 19 mm Magna/Inspiris, there were no significant differences in left ventricular remodeling and long-term outcomes between the two groups.

Abstract
BACKGROUND Routine thrombus aspiration (TA) does not improve clinical outcomes in patients with ST-segment-elevation myocardial infarction (STEMI), although data from meta-analyses suggest that patients with high thrombus burden may benefit from it. The impact of TA on left ventricular (LV) functional recovery and remodeling after STEMI remains controversial. We aimed to pool data from randomized controlled trials (RCTs) on the impact of TA on LV function and remodeling after primary percutaneous coronary intervention (pPCI). METHODS PubMed and CENTRAL databases were scanned for eligible studies. Primary outcome measures were: LV ejection fraction (LVEF), LV end diastolic volume (LVEDV), LV end systolic volume (LVESV) and wall motion score index (WMSI). A primary pre-specified subgroup analysis was performed comparing manual TA with mechanical TA. RESULTS A total of 28 studies enrolling 4990 patients were included. WMSI was lower in TA group than in control (mean difference [MD] -0.11, 95% confidence interval [CI] -0.19 to -0.03). A greater LVEF (MD 1.91, 95% CI 0.76 to 3) and a smaller LVESV (MD -6.19, 95% CI -8.7 to -3.6) were observed in manual TA group compared to control. Meta regressions including patients with left anterior descending artery (LAD) involvement showed an association between TA use and the reduction of both LVEDV and LVESV (z = -2.13, p = 0.03; z = -3.7, p < 0.01) and the improvement in myocardial salvage index (z = 2.04, p = 0.04). CONCLUSION TA is associated with improved LV function. TA technique, total ischemic time and LAD involvement appears to influence TA benefit on post-infarction LV remodeling.

Abstract
BACKGROUND AND OBJECTIVE We aimed to investigate long-term clinical and echocardiographic outcomes, including tricuspid valve durability, annular growth, and left ventricular reverse remodeling, after modified cone reconstruction in patients with Ebstein's anomaly. METHODS This was a retrospective analysis of all pediatric patients who underwent modified cone reconstruction for Ebstein's anomaly at a single tertiary center between January 2005 and June 2021. RESULTS A total of 14 pediatric patients underwent modified cone reconstruction for Ebstein's anomaly; the median age was 5.8 years (range, 0.01-16.6). There were three patients (21.4%) with Carpentier type B, ten patients with Carpentier type C (71.4%), and one patient with Carpentier type D (7.1%). There was no early or late mortality, arrhythmia, or readmission for heart failure at a 10-year follow-up. There were no cases of more than mild tricuspid stenosis or more than moderate tricuspid regurgitation during the study period, except for one patient with severe tricuspid regurgitation who underwent reoperation. The z value for tricuspid valve annular size significantly decreased immediately after the operation (2.46 vs. -1.15, p<0.001). However, from 1 year to 7 years after surgery, the z values were maintained between -1 and +1. Left ventricular end-systolic volume, end-diastolic volume, and stroke volume increased after surgery and remained elevated until seven years postoperatively. CONCLUSIONS Ebstein's anomaly in children can be repaired by modified cone reconstruction with low mortality and morbidity, good tricuspid valve durability, and annular growth relative to somatic growth.

Abstract
The effect of electronic cigarette (E-cig) vaping on cardiac and vascular function during the healing phase of myocardial infarction (MI), and post-MI remodeling was investigated. Sprague Dawley rats were subjected to left coronary artery ligation to induce MI. One week later, rats were randomized to receive either 12 weeks of exposure to purified air (n = 37) or E-cig vapor (15 mg/ml of nicotine) (n = 32). At 12 weeks, cardiac and vascular function, and post-MI remodeling were assessed. Baseline blood flow in the femoral artery did not differ between groups, but peak reperfusion blood flow was blunted in the E-cig group (1.59 ± 0.15 ml/min) vs. the air group (2.11 ± 0.18 ml/min; p = 0.034). Femoral artery diameter after reperfusion was narrower in the E-cig group (0.54 ± 0.02 mm) compared to the air group (0.60 ± 0.02 mm; p = 0.023). Postmortem left ventricular (LV) volumes were similar in the E-cig (0.69 ± 0.04 ml) and air groups (0.73 ± 0.04 ml; p = NS); and myocardial infarct expansion index did not differ between groups (1.4 ± 0.1 in E-cig group versus 1.3 ± 0.1 in air group; p = NS). LV fractional shortening by echo did not differ between groups at 12 weeks (E-cig at 29 ± 2% and air at 27 ± 1%; p = NS). Exposure to E-cig during the healing phase of MI was associated with altered vascular function with reduced femoral artery blood flow and diameter at reperfusion, but not with worsened LV dilation or worsened cardiac function.

Abstract
INTRODUCTION Malnutrition during a critical window of development in a fetus or infant can result in abnormal cardiac remodeling and function. It is uncertain whether the contribution of these effects continues to impact the cardiac remodeling and function of adults over the course of several decades of growth. Our study examined the impact of early Chinese famine exposure on cardiac remodeling, left ventricular (LV) diastolic function, and LV systolic function in adults. METHODS Participants at high risk of cardiovascular disease from the China Patient-Centered Evaluative Assessment of Cardiac Events Million Persons Project (PEACE MPP) were enrolled. The famine in China lasted from 1959 to 1962. A total of three groups were formed based on the participants' birth dates: pre-famine group, famine exposure group, and post-famine group. Logistic regression and linear mixed models were used to explore the association between famine exposure and cardiac remodeling, LV diastolic function and LV systolic function in adults. RESULTS The study included 2,758 participants, the mean age was 57.05 years, 62.8% were female, 26.4% had LV hypertrophy (LVH), 59.6% had LV diastolic dysfunction (LVDD), and 10.5% had reduced global longitudinal strain (GLS). Compared to post-famine exposure, participants had independently increased risk of LVH in the famine exposure group (OR: 2.02, 95% CI: 1.60-2.56) and pre-famine exposure (OR: 1.36, 95% CI: 1.06-1.76). Compared to post-famine exposure, the risk of LVDD remarkably increased in the famine exposure group (OR: 3.04, 95% CI: 2.49-3.71) and pre-famine exposure group (OR: 1.87, 95% CI: 1.52-2.31). Famine exposure had no significant impact on GLS but was associated with a significant increase in LV ejection fraction (LVEF) and LV end-diastolic diameter (LVEDD). Significant interactions were observed between the effects of famine exposure and other clinical/sociodemographic variables (gender, systolic blood pressure [SBP] ≥140 mm Hg or not, high school or above or not, and annual income <50,000 RMB or not) on these outcomes. CONCLUSION Exposure to famine, particularly during fetal and infant stages, increases the risk of LVH and LVDD in adults. However, the LV systolic function remains preserved. These impacts are more pronounced in females, individuals with SBP ≥140 mm Hg, those with low income, or those with high educational status.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ling-Qui-Qi-Hua (LGQH) decoction, composed of Poria cocos (Schw.) Wolf, Cinnamomum cassia (L.) J. Presl, Paeonia veitchii Lynch, and Atractylodes macrocephala Koidz., is a compound formula derived from Ling-Gui-Zhu-Gan decoction recorded in the Treatise on Febrile and Miscellaneous. It has shown cardioprotective effects on patients or rats with heart failure with preserved ejection fraction (HFpEF). Nevertheless, the active ingredients of LGQH and its anti-fibrotic mechanism remain unknown. AIM OF THE STUDY To determine the active ingredients in LGQH decoction and verify that LGQH decoction may inhibit left ventricular (LV) myocardial fibrosis in HFpEF rats by blocking the transforming growth factor-β1 (TGF-β1)/Smads signaling pathway from the perspective of animal experiments. MATERIALS AND METHODS First, liquid chromatography-mass spectrometry (LC-MS) technology was used to identify active components in the LGQH decoction. Secondly, a rat model of the metabolic syndrome-associated HFpEF phenotype was established and subsequently received LGQH intervention. The mRNA and protein expression of targets in the TGF-β1/Smads pathway were detected by quantitative real-time polymerase chain reaction and western blot analysis. Finally, molecular docking was conducted to examine the interactions between the active ingredients in the LGQH decoction and key proteins of the TGF-β1/Smads pathways. RESULTS According to LC-MS analysis, the LGQH decoction contained 13 active ingredients. In animal experiments, LGQH attenuated LV hypertrophy, enlargement, and diastolic function in HEpEF rats. Mechanically, LGQH not only down-regulated TGF-β1, Smad2, Smad3, Smad4, α-SMA, Coll I, and Coll III mRNA expressions and TGF-β1, Smad2, Smad3, P-Smad2/Smad3, Smad4, α-SMA, and Coll I protein expressions, but also up-regulated Smad7 mRNA and protein expressions, which ultimately led to myocardial fibrosis. Furthermore, molecular docking confirmed that 13 active ingredients in the LGQH decoction have excellent binding activities to the critical targets of the TGF-β1/Smads pathway. CONCLUSION LGQH is a modified herbal formulation with multiple active ingredients. It might alleviate LV remodeling and diastolic dysfunction and inhibit LV myocardial fibrosis by blocking TGF-β1/Smads pathways in HFpEF rats.

Abstract
The current study evaluated the effect of SGLT-2 inhibitor, dapagliflozin, on left ventricular remodeling in patients with type 2 diabetes and HFrEF. 60 patients were randomized (1:1) to receive dapagliflozin 10 mg once daily, or placebo double blind for 1 year. Patients underwent transthoracic echocardiography and doppler evaluation prior to dapagliflozin initiation and at 1 year. At 1year, adjusted mean difference versus placebo in change from baseline in LVEF was 2.5% (95% CI: 1.00-4.06, P = 0.002). Adjusted mean difference versus placebo in change from baseline in LVED volume was - 6.0ml (95% CI: -8.07 --3.87, P<0.001). Adjusted mean difference versus placebo in change from baseline in LVES volume was - 8.1ml (95% CI: -11.07 --5.14, P<0.001). Similarly, adjusted mean difference versus placebo in change from baseline in LVED diameter was - 1.6 mm (95% CI: -2.67 --0.62, P = 0.002). Adjusted mean difference versus placebo in change from baseline in VTI was 0.20 cm (95% CI: 0.01-0.38, P = 0.036). Dapagliflozin was well tolerated. Dapagliflozin was associated with significant and clinically meaningful improvement in echocardiographic parameters versus placebo in patients with type 2 diabetes and HFrEF.Registration number and date: ChiCTR2300072707, 21/06/2023.

Abstract
Aortic stenosis (AS) is a dynamic degenerative process that shares many pathophysiological features with atherogenesis, from initial proinflammatory calcification and focal thickening of the valve leaflets to obstruction of left ventricular outflow due to superimposed of severe calcification and immobilization of the valve leaflets. As the prevalence increases with age, AS is expected to become one of the most common heart diseases worldwide. In both obese and nonobese patients, persistent thickening of epicardial adipose tissue (EAT) is associated with a shift in its normal metabolic functions toward a dysmetabolic and proatherogenic phenotype that may impair the physiology of adjacent coronary arteries and promote the occurrence of coronary atherosclerosis. In tight analogy with atherosclerosis, recent clinical evidence indicates that EAT may also exert a deleterious role in promoting AS and contributing to myocardial dysfunction, leading to increased health risk for elderly patients with AS and an economic burden on the health care system. This review discusses the clinical and pathologic evidence for the association between EAT and AS and concomitant left ventricular hypertrophy, and provides new insights for the future direction of AS diagnosis and treatment.

Abstract
BACKGROUND Standard ECG criteria for left ventricular (LV) hypertrophy rely on QRS amplitudes. However, in the setting of left bundle branch block (LBBB), ECG correlates of LV hypertrophy are not well established. We sought to evaluate quantitative ECG predictors of LV hypertrophy in the presence of LBBB. METHODS We included adult patients with typical LBBB having ECG and transthoracic echocardiogram performed within 3 months of each other in 2010-2020. Orthogonal X, Y, Z leads were reconstructed from digital 12‑lead ECGs using Kors's matrix. In addition to QRS duration, we evaluated QRS amplitudes and voltage-time-integrals (VTIs) from all 12 leads, X, Y, Z leads and 3D (root-mean-squared) ECG. We used age, sex and BSA-adjusted linear regressions to predict echocardiographic LV calculations (mass, end-diastolic and end-systolic volumes, ejection fraction) from ECG, and separately generated ROC curves for predicting echocardiographic abnormalities. RESULTS We included 413 patients (53% women, age 73 ± 12 years). All 4 echocardiographic LV calculations were most strongly correlated with QRS duration (all p < 0.00001). In women, QRS duration ≥ 150 ms had sensitivity/specificity 56.3%/64.4% for increased LV mass and 62.7%/67.8% for increased LV end-diastolic volume. In men, QRS duration ≥ 160 ms had a sensitivity/specificity 63.1%/72.1% for increased LV mass and 58.3%/74.5% for increased LV end-diastolic volume. QRS duration was best able to discriminate eccentric hypertrophy (area under ROC curve 0.701) and increased LV end-diastolic volume (0.681). CONCLUSIONS In patients with LBBB, QRS duration (≥ 150 in women and ≥ 160 in men) is a superior predictor of LV remodeling esp. eccentric hypertrophy and dilation.

Abstract
Background Left ventricular dyssynchrony (LVD) and postextrasystolic potentiation (PESP) associated with premature ventricular contractions (PVCs) may play a role in the development of premature ventricular contraction-induced cardiomyopathy (PVC-CM). Long-coupled (LC) PVCs have a greater LVD than short-coupled (SC) PVCs, whereas SC-PVCs have a stronger PESP than LC-PVCs. Objective The purpose of this study was to compare SC-PVCs and LC-PVCs to evaluate the roles of LVD, PESP, and atrioventricular dissociation (AVD) in the development of PVC-CM. Methods Thirty-six canines underwent pacemaker implantation to induce bigeminal right ventricular apical epicardial PVCs (50% burden) for 12 weeks. Telemetry assessed PVC burden and AVD. Animals were grouped as SC-PVC (coupling interval [CI] 200-220ms), LC-PVC (CI 330 ms), or sham (control). Echocardiographic changes, AVD, and hemodynamics were monitored for 12 weeks. Results PVC burden was similar between SC-PVC and LC-PVC groups but was statistically higher in the SC-PVC group (50% vs 47.5%; P = .028). After 12 weeks, left ventricular ejection fraction (LVEF) significantly decreased in both SC-PVC and LC-PVC groups (47.1% ± 1.4% and 45.5% ± 2%, respectively) compared to sham group (61% ± 1.6%; P <.001). Overall AVD was similar between SC-PVC and LC-PVC groups, and there was no significant correlation between AVD and reduction in LVEF at 12 weeks (r = 0.09, P = .5; and r = 0.06, P = .8, respectively). Additionally, both SC-PVC and LC-PVC groups experienced substantial declines in max and min dP/dt after 12 weeks compared to baseline. Conclusion Neither PVC CI nor AVD played an independent role in the development or severity of PVC-CM. LVD and PESP make equal relative contributions to the development of PVC-CM.

Abstract
BACKGROUND Insulin is commonly used in type 2 diabetes mellitus (T2DM) to achieve glycemic control. However, recent evidence showed that insulin use is associated with poor outcomes in the context of heart failure (HF). Since heart failure with reduced ejection fraction (HFrEF) accounts for approximately 50% of cases in the general HF population, we aimed to evaluate the effect of insulin treatment on left ventricular (LV) remodeling and contractility abnormalities in a HFrEF cohort and assess whether insulin was a predictor of adverse outcomes in this entity. METHODS A total of 377 HFrEF patients who underwent cardiac MRI were included and divided according to diabetes status and the need for insulin treatment. LV structural and functional indices, as well as systolic strains, were measured. The determinants of impaired myocardial strains were assessed using linear regression analysis. The associated endpoints were determined using a multivariable Cox proportional hazards model. RESULTS T2DM patients on insulin displayed a higher indexed LV end-diastolic volume and LV mass than those with T2DM not on insulin or those without T2DM, despite similar LV ejection fractions, accompanied by a higher three-dimensional spherical index (P < 0.01). Worse longitudinal and circumferential peak systolic strain was shown to occur in T2DM patients on insulin (P < 0.01). Insulin treatment was independently associated with impaired magnitudes of systolic strain. The median follow-up duration was 32.4 months (IQR, 15.6-43.2 months). Insulin treatment remained consistently associated with poor outcomes after adjustment for established confounders, with an adjusted hazard ratio of 3.11; (95% CI, 1.45-6.87; P = 0.009) in the overall cohort and 2.16 (95% CI, 1.08-4.59; P = 0.030) in the diabetes cohort. CONCLUSIONS Insulin may further lead to adverse LV remodeling and contractile dysfunction in the context of HFrEF with T2DM. Considerable care should be taken when treating HFrEF patients with insulin.

Abstract
BACKGROUND Cardiac remodeling and dysfunction can be caused by atrial fibrillation (AF). The aim of this research is to investigate the relationship between the systemic inflammatory response index (SIRI) and left ventricular (LV) remodeling and systolic function in individuals with AF. METHODS 416 patients with AF who were admitted to the Second Department of Cardiology in the East Ward of the Qingdao Municipal Hospital between January 2020 and May 2022 were included in the present retrospective research. The relationship between SIRI and various cardiac parameters was analyzed. The patients' left atrial (LA) enlargement and left ventricular (LV) hypertrophy and systolic dysfunction were evaluated. SIRI was calculated by the formula: neutrophil × monocyte/lymphocyte. RESULTS SIRI significantly correlated with LV end-diastolic diameter (LVDd), LV posterior wall thickness at end-diastole (LVPWTd), interventricular septal thickness at end-diastole (IVSTd), LV mass index (LVMI), LV ejection fraction (LVEF), LA diameter (LAD), C-reactive protein (CRP), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with AF. In multivariate linear regression analyses, SIRI was discovered to be significantly related to LVMI (ln-transformed) (p = 0.025), LVEF (ln-transformed) (p = 0.005), and LAD (ln-transformed) (p = 0.007). In multivariate logistic regression, the highest quartile of SIRI (SIRI > 1.62) was significantly associated with LV hypertrophy (p = 0.026), impaired LV systolic function (p = 0.002), and LA enlargement (p = 0.025). CONCLUSIONS SIRI was significantly associated with LV remodeling and systolic function impairment in patients with AF. SIRI may serve as a reliable and convenient inflammatory biomarker for detecting impaired cardiac structure and systolic function in patients with AF.

Abstract
Rheumatoid arthritis (RA) patients have a 1.5- to twofold higher risk of developing heart failure (HF) and a twofold increased risk of HF-associated mortality compared to those without RA. HF is preceded subclinically by left ventricular (LV) remodeling in the general population. There is a relative absence of prospective studies following RA patients from pre-clinical to clinical HF as well as prospective studies of LV remodeling in RA without clinical HF. In our study, 158 RA patients without clinical HF were enrolled and underwent transthoracic echocardiography (TTE) at baseline and on follow-up between 4 and 6 years. Extensive characterization of RA disease activity and cardiovascular risk factors were performed. LV remodeling was prevalent at 40% at baseline and increased to 60% over time. Higher levels of interleukin-6 (IL 6) were associated with concentric LV remodeling on follow-up. The use of tocilizumab was also significantly associated with baseline LV remodeling (relative wall thickness). These findings suggest a role for IL-6 as a biomarker for LV remodeling in RA patients without clinical HF. Future research should focus on prospective follow-up of LV remodeling and the effects of IL-6 inhibition on LV remodeling in RA patients.

Abstract
Introduction Collateral formation is insufficient in some patients with acute myocardial infarction (AMI). Peripheral blood CD14++CD16+ monocytes (intermediate monocytes; IM) and vascular endothelial growth factors (VEGFs) are associated with formation of collateral circulation. Methods We enrolled 49 patients with AMI who underwent emergency percutaneous transluminal coronary intervention (PCI) (Group A) and 27 patients underwent delayed PCI 1 week after AMI (Group B). The percentage of circulating IM and levels of VEGFs in circulation were determined on day 8th. Left ventricular ejection fraction (LVEF) was measured 3 months after AMI. Results The peripheral levels of IM and serum VEGF levels on day 8th were significantly higher in patients with well-developed collateral circulation in Group A than those in Group B. The levels of circulating VEGFs in the collateral circulation (+) subgroup in Group B were lower than those in the collateral circulation (-) subgroup. Moreover, the serum VEGF-B186 levels positively correlated with IM. Conclusions Hyperacute collateral formation in patients with AMI correlated with a higher percentage of CD14++CD16+ monocytes and VEGF-B186 levels in the circulation, which was associated with milder left ventricular remodeling. The regulation of CD14++CD16+ monocytes and VEGF-B may be critical to the formation of collateral circulation and to healing AMI.

Abstract
BACKGROUND Aortic regurgitation (AR) can develop in adults with repaired coarctation of aorta (COA), but there are limited data about left ventricular (LV) remodeling and clinical outcomes in this population. The purpose of the study was to compare LV remodeling (LV mass index [LVMI], LV ejection fraction [LVEF], and septal E/e') and onset of symptoms before aortic valve replacement, and LV reverse remodeling (%-change in LVMI, LVEF and E/e') after aortic valve replacement in patients with versus without repaired COA presenting with AR. METHODS Asymptomatic adults with repaired COA presenting with moderate/severe AR (AR-COA group) were matched 1:2 to asymptomatic adults without COA and similar severity of AR (control group). RESULTS Although both groups (AR-COA n = 52, and control n = 104) had similar age, sex, body mass index, aortic valve gradient, and AR severity, the AR-COA group had higher LVMI (124 ± 28 versus 102 ± 25 g/m2, p < 0.001) and E/e' (12.3 ± 2.3 versus 9.5 ± 2.1, p = 0.02) but similar LVEF (63 ± 9% versus 67 ± 10%, p = 0.4). COA diagnosis (adjusted HR 1.95, 95%CI 1.49-2.37, p < 0.001), older age, E/e', and LV hypertrophy were associated with onset of symptoms. Of 89 patients (AR-COA n = 41, and control n = 48) with echocardiographic data at 1-year post- aortic valve replacement, the AR-COA group had less regression of LVMI (-8% [95%CI -5 to -11] versus -17% [95%CI -15 to -21], p < 0.001) and E/e' (-5% [95% CI -3 to -7] versus -16% [95% CI -13 to -19], p < 0.001). CONCLUSIONS Patients with COA and AR had a more aggressive clinical course, and perhaps may require a different threshold for surgical intervention.

Abstract
BACKGROUND Anemia in patients with chronic kidney disease (p-CKDs) may initiate or exacerbate left ventricular hypertrophy (LVH). This study aimed to determine whether treatment using long-acting erythropoietin-stimulating agents (L-ESAs) is independently associated with LVH during the pre-dialysis to maintenance dialysis period in p-CKDs. METHODS Physical and laboratory examinations were performed 120 days before initiating dialysis in p-CKDs (baseline). To evaluate the left ventricular mass index (LVMI) after starting dialysis, the mean hemoglobin (Hb) was defined as the average at the start of dialysis and 6 months after starting dialysis. Changes in the LVMI were observed in three groups according to mean Hb levels (Hb < 10.1, 10.1 < Hb < 11.0, and Hb > 11.0 g/dL for Groups 1, 2, and 3, respectively). LVMI was evaluated using echocardiography at the pre-dialysis, initiation, and maintenance dialysis periods. RESULTS A lower LVMI at dialysis initiation and an improvement in LVMI were detected in the highest tertile group of mean Hb (11.0 g/dl). Consequently, in the high Hb group (Hb level > 11.0 g/dl), LVMI remained low from dialysis initiation until after 6 months.The relationship between Hb and LVMI was not significant; however, a constant correlation with β ≥ 0.4 in the absolute value was maintained. CONCLUSION L-ESAs may correlate with Hb and LVMI after administration, independent of the baseline LVMI and Hb values. These findings have therapeutic implications in the treatment strategies for p-CKDs during the pre-dialysis to maintenance dialysis period.

Abstract
OBJECTIVES A complex relationship of adipokines and cytokines with cardiovascular risk motivates the use of an integrated approach to identify early signs of adiposity-related inflammation. We compared the inflammatory profiles, including an integrated inflammatory score, and cardiovascular profiles of young adults who are living with overweight and/or obesity (OW/OB). DESIGN AND METHODS This cross-sectional study included 1194 men and women with a median age of 24.5 ± 3.12 years from the African Prospective study on the Early Detection and Identification of Cardiovascular disease and Hypertension (African-PREDICT). Participants were divided into approximate quartiles based on adiposity measures (body mass index, waist circumference, and waist-to-height ratio). We compared an integrated inflammatory score (including leptin, adiponectin, interleukin-6, interleukin-8, interleukin-10, and tumour necrosis factor-α) as well as the individual inflammatory markers, between extreme quartiles. We also compared blood pressure measures, left ventricular mass index, carotid-femoral pulse wave velocity, and carotid intima-media thickness between these groups. RESULTS Individuals in the top quartile had worse inflammatory- and cardiovascular profiles as the integrated inflammatory score, leptin, interleukin-6, blood pressure measures, and left ventricular mass index were higher, while adiponectin was lower (all p ≤ 0.003). Unexpectedly, carotid-femoral pulse wave velocity was also lower (p < 0.001) in the top quartile. Exclusively in the top quartile, all adiposity measures related positively with the integrated inflammatory score and central systolic blood pressure (both r ≥ 0.24; p < 0.001), and negatively with interleukin-10 (all r ≤ -0.13; p < 0.03). Of these relationships, the correlations with the integrated inflammatory score were the strongest (p < 0.001). The percentage difference of being in the top quartile of all adiposity measures were higher for the inflammatory score (all ≥ 263 %), leptin (all ≥ 175 %), interleukin-6 (all ≥ 134 %), and tumour necrosis factor-α (all ≥ 26 %), and lower for adiponectin (all ≥ 57 %), interleukin-10 (all ≥ 9 %), and interleukin-8 (all ≥ 15 %) compared to being in the bottom quartile. CONCLUSION The inflammatory score, as a comprehensive marker of adiposity-related inflammation, is strongly related to adiposity and may be an indication of early cardiovascular risk in young adults; however, further work is required to establish the clinical use thereof.

Abstract
Objective To evaluate with 7T cardiac magnetic resonance tissue tracking imaging (CMR-TT) the ameliorative effect of Cang-ai volatile oil (CAVO) on left ventricular remodeling (LVR) in rats induced by isoproterenol (ISO), and to make preliminary investigation into CAVO's effects on endothelial dysfunction in LVR. Methods A total of 35 healthy male Sprague-Dawley (SD) rats were randomly assigned to two groups, the experimental group ( n=27) and the normal control group ( n=8). The rat model of LVR was established by subcutaneous injection of ISO solution at 10 mg·kg -1·d -1 at multiple sites for 10 consecutive days. After modeling was completed, the surviving rats ( n=24) in the experimental group were then randomly assigned to the blank experimental group, CAVO group, and Shexiang Baoxin pill (SXBXP) group ( n=8 in each group). Rats in each group were given via gavage the corresponding intervention medicine or an equivalent amount of normal saline solution for 28 consecutive days. At the end of modeling and intragastric intervention, 7T CMR cine sequence scanning was conducted to collect data. Then, post-processing software CVI42 was used to analyze the images and to compare and contrast the changes in the parameters of left ventricular cardiac function and myocardial strain in each group before and after the administration of the medication. The rats were sacrificed after MRI scanning, and their hearts were harvested for pathological examination. The levels of serum biochemical indicators were measured by enzyme-linked immunosorbent assay (ELISA). Results CAVO significantly increased LV ejection fraction and overall myocardial strain parameters in LVR rats, while it decreased LV volume, mass, and serum levels of endothelial function indicators in LVR rats. In addition, pathological staining showed marked improvements in the hypertrophy, necrosis and interstitial fibrosis of cardiomyocytes. Conclusion Through the regulation of myocardial vascular endothelial function, CAVO can significantly improve cardiac functions in LVR rats, delay the process of ventricular remodeling, and have a certain amount of protective effect on cardiac structure and function in rats.

Abstract
PURPOSE To assess predictive value of 68Ga-labeled fibroblast activation protein inhibitor-04 ([68Ga]Ga-DOTA-FAPI-04) PET/MR for late left ventricular (LV) remodeling in patients with ST-segment elevated myocardial infarction (STEMI). METHODS Twenty-six patients with STEMI were included in the study. [68Ga]Ga-DOTA-FAPI-04 PET/MR was performed at baseline and at average 12 months after STEMI. LV remodeling was defined as >10% increase in LV end-systolic volume (LVESV) from baseline to 12 months. RESULTS The LV remodeling group demonstrated higher [68Ga]Ga-DOTA-FAPI-04 uptake volume (UV) at baseline than the non-LV remodeling group (p < 0.001). [68Ga]Ga-DOTA-FAPI-04 UV at baseline was a significant predictor (OR = 1.048, p = 0.011) for LV remodeling at 12 months after STEMI. Compared to clinical information, MR imaging and cardiac function parameters at baseline, [68Ga]Ga-DOTA-FAPI-04 UV demonstrated better predictive ability (AUC = 0.938, p < 0.001) for late LV remodeling, with sensitivity of 100.0% and specificity of 81.3%. CONCLUSIONS [68Ga]Ga-DOTA-FAPI-04 PET/MR is an effective tool to non-invasively quantify myocardial fibroblasts activation, and baseline [68Ga]Ga-DOTA-FAPI-04 UV may have potential predictive value for late LV remodeling.

Abstract
Acute ST-segment elevation myocardial infarction (STEMI) is associated with left ventricular (LV) structural and functional consequences. We aimed to elucidate LV geometric changes following STEMI using three-dimensional (3D) echocardiography (3DE) and to assess their functional implications using two-dimensional (2D) speckle tracking echocardiography (STE). The study included 71 patients with STEMI who underwent baseline and 6-month follow-up 2D- and 3DE. Measured parameters included LV dimensions, biplane volumes, wall motion assessment, 2D LV global longitudinal strain (GLS), and 3D LV volumes, sphericity index and systolic dyssynchrony index. According to 3DE, LV geometric changes were classified as, adverse remodeling, reverse remodeling, and minimal LV volumetric changes. The occurrence of in-hospital and follow-up major adverse cardiovascular events (MACE) was assessed among the study population. The incidence of developing adverse remodeling was 25.4% while that of reverse remodeling was 36.6%. Adverse remodeling patients had significantly higher in-hospital MACE. Reverse remodeling was associated with significantly improved GLS, that was less evident in those with minimal LV geometric changes, and non-significant improvement for adverse remodeling group. LV baseline 2D GLS significantly correlated with follow-up 3D volumes among both reverse and adverse remodeling groups. Female gender and higher absolute GLS change upon follow-up were significantly associated with reverse remodeling. ROC-derived cutoff for adverse remodeling reallocated a substantial number of patients from the minimal change group to the adverse remodeling. Following acute STEMI, two-dimensional GLS was associated with and potentially predictive of changes in LV volumes as detected by three-dimensional echocardiography.

Abstract
BACKGROUND Myocardial infarction leads to complex changes in left ventricular (LV) hemodynamics. It remains unknown how four-dimensional acute changes in LV-cavity blood flow kinetic energy affects LV-remodeling. METHODS AND RESULTS In total, 69 revascularised ST-segment elevation myocardial infarction (STEMI) patients were enrolled. All patients underwent cardiovascular magnetic resonance (CMR) examination within 2 days of the index event and at 3-month. CMR examination included cine, late gadolinium enhancement, and whole-heart four-dimensional flow acquisitions. LV volume-function, infarct size (indexed to body surface area), microvascular obstruction, mitral inflow, and blood flow KEi (kinetic energy indexed to end-diastolic volume) characteristics were obtained. Adverse LV-remodeling was defined and categorized according to increase in LV end-diastolic volume of at least 10%, 15%, and 20%. Twenty-four patients (35%) developed at least 10%, 17 patients (25%) at least 15%, 11 patients (16%) at least 20% LV-remodeling. Demographics and clinical history were comparable between patients with/without LV-remodeling. In univariable regression-analysis, A-wave KEi was associated with at least 10%, 15%, and 20% LV-remodeling (p = 0.03, p = 0.02, p = 0.02, respectively), whereas infarct size only with at least 10% LV-remodeling (p = 0.02). In multivariable regression-analysis, A-wave KEi was identified as an independent marker for at least 10%, 15%, and 20% LV-remodeling (p = 0.09, p < 0.01, p < 0.01, respectively), yet infarct size only for at least 10% LV-remodeling (p = 0.03). CONCLUSION In patients with STEMI, LV hemodynamic assessment by LV blood flow kinetic energetics demonstrates a significant inverse association with adverse LV-remodeling. Late-diastolic LV blood flow kinetic energetics early after acute MI was independently associated with adverse LV-remodeling.

Abstract
BACKGROUND Coronary artery disease (CAD) is a metabolically perturbed pathological condition. However, the knowledge of metabolic signatures on outcomes of CAD and their potential causal effects and impacts on left ventricular remodeling remains limited. We aim to assess the contribution of plasma metabolites to the risk of death and major adverse cardiovascular events (MACE) as well as left ventricular remodeling. RESULTS In a prospective study with 1606 Chinese patients with CAD, we have identified and validated several independent metabolic signatures through widely-targeted metabolomics. The predictive model respectively integrating four metabolic signatures (dulcitol, β-pseudouridine, 3,3',5-Triiodo-L-thyronine, and kynurenine) for death (AUC of 83.7% vs. 76.6%, positive IDI of 0.096) and metabolic signatures (kynurenine, lysoPC 20:2, 5-methyluridine, and L-tryptophan) for MACE (AUC of 67.4% vs. 59.8%, IDI of 0.068) yielded better predictive value than trimethylamine N-oxide plus clinical model, which were successfully applied to predict patients with high risks of death (P = 0.0014) and MACE (P = 0.0008) in the multicenter validation cohort. Mendelian randomisation analysis showed that 11 genetically inferred metabolic signatures were significantly associated with risks of death or MACE, such as 4-acetamidobutyric acid, phenylacetyl-L-glutamine, tryptophan metabolites (kynurenine, kynurenic acid), and modified nucleosides (β-pseudouridine, 2-(dimethylamino) guanosine). Mediation analyses show that the association of these metabolites with the outcomes could be partly explained by their roles in promoting left ventricular dysfunction. CONCLUSIONS This study provided new insights into the relationship between plasma metabolites and clinical outcomes and its intermediate pathological process left ventricular dysfunction in CAD. The predictive model integrating metabolites can help to improve the risk stratification for death and MACE in CAD. The metabolic signatures appear to increase death or MACE risks partly by promoting adverse left ventricular dysfunction, supporting potential therapeutic targets of CAD for further investigation.

Abstract
To determine the relationship between aortic distensibility and left ventricular (LV) remodeling, myocardial strain and blood biomarkers in patients with stenotic bicuspid aortic valve (BAV) and preserved ejection fraction (EF) by cardiovascular magnetic resonance (CMR). 43 stenotic BAV patients were prospectively selected for 3.0 T CMR. Patients were divided into LV remodeling group (LV mass/volume ≥ 1.15, n = 21) and non-remodeling group (LV mass/volume < 1.15, n = 22). Clinical characteristics, biochemical data including cardiac troponin T(cTNT), N-terminal pro-B type natriuretic peptide (NT-proBNP) and creatine kinase isoenzyme (CK-MB) were noted. Distensibility of middle ascending aorta (mid-AA) and proximal descending aorta, LV structural and functional parameters, global and regional myocardial strain were measured. Compared to non-remodeling group, LV remodeling group had significantly decreased LV global strain (radial: 26.04 ± 8.70% vs. 32.92 ± 7.81%, P = 0.009; circumferential: - 17.20 ± 3.38% vs. - 19.65 ± 2.34%, P = 0.008; longitudinal: - 9.13 ± 2.34% vs. - 11.63 ± 1.99%, P < 0.001) and decreased mid-AA distensibility (1.22 ± 0.24 10-3 mm/Hg vs 1.60 ± 0.41 10-3 mm/Hg, P = 0.001). In addition, mid-AA distensibility was independently associated with LV remodeling (β = - 0.282, P = 0.003), and it was also significantly correlated with LV global strain (radial: r = 0.392, P = 0.009; circumferential: r = - 0.348, P = 0.022; longitudinal: r = - 0.333, P = 0.029), cTNT (r = - 0.333, P = 0.029) and NT-proBNP (r = - 0.440, P = 0.003). In this cohort with stenotic BAV and preserved EF, mid-AA distensibility is found significantly associated with LV remolding, which encouraging to better understand mechanism of ventricular vascular coupling.

Abstract
AIMS Visceral fat (VF) influences left ventricular (LV) structure and diastolic function in type 2 diabetes (T2DM). However, there are limited data on the association among them based on different BMI levels as well as accounting for arterial stiffness. This study investigated the association of fat distribution, arterial stiffness, left ventricular (LV) structure and diastolic function in T2DM patients. MATERIALS AND METHODS This cross-sectional study comprised 905 patients. VF area (VFA) and subcutaneous fat area (SFA) were assessed by a dual bioelectrical impedance analyzer. Brachial-ankle pulse wave velocity (baPWV) was measured by a volume-plethysmographic apparatus and LV structure and diastolic function were echocardiography. Patients were divided into three groups based on BMI levels. Linear and logistic regression analysis were used to investigate the association. RESULTS In multivariate linear regression, relative wall thickness (RWT) was negatively correlated with E/A in obese patients (β = -0.203, p = 0.004). LV mass/height2.7 was positively correlated with E/E' in normal weight (β = 0.232, p = 0.002) and obese patients (β = 0.232, p = 0.008). In multivariate logistic regression, baPWV was an independent determinant of LV remodeling (LVRM) in normal weight (OR = 1.001; 95% CI, 1.000, 1.002; P = 0.006), overweight (OR = 1.001; 95% CI, 1.000, 1.002; P = 0.008) and obese groups (OR = 1.003; 95% CI, 1.001, 1.004; P = 0.001), while VFA was correlated with arterial stiffness in normal weight (OR = 1.032; 95% CI, 1.017, 1.047; P < 0.001) and overweight groups (OR = 1.011; 95% CI, 1.002, 1.021; P = 0.015). CONCLUSIONS VF might impact LVRM through changes in baPWV in T2DM patients, thus influencing diastolic function.

Abstract
Background Whether cigarette smoking affects the heart post-myocardial infarction (MI) in a sex-dependent way remains controversial. Using a mouse model, we investigated cardiac remodeling under the influence of acute cigarette smoke (CS) exposure following ischemic injury in both sexes. Methods Ten cigarettes were smoked twice daily for 2 weeks followed by MI and then 1 additional week post permanent LAD ligation. Cardiac function, histology, and infarct size were assessed, and inflammatory markers quantified by RT–PCR. Statistical comparisons were performed using an unpaired t test or ANOVA followed by Tukey post hoc test. Results We observed that cigarette smoking exacerbated both left and right ventricular remodeling only in males at an early stage of post-MI. Females did not display a significant structural and/or functional alteration within 7 days of cardiac remodeling post-MI upon CS exposure. Worsened right ventricular remodeling in males was independent of pulmonary congestion. CS-exposed males exhibited enhanced increases in left ventricular end systolic and diastolic volumes, as well as reductions in ejection fraction and fractional area changes of left ventricular base. At day 7, infarct size was increased by cigarette smoking in males only, which was accompanied by enhanced collagen deposition in both the infarcted and peri-infarcted areas. Both IL-6 and TNF-α mRNA expression significantly increased in CS-exposed MI male group only at day 7 post-MI suggestive of prolonged inflammation. Conclusions These findings indicate that CS exposure worsens the progression of cardiac remodeling post-MI in male sex in a significant manner compared to female sex at least at early stages.

Abstract
Background Recent data showed poor long-term survival in patients with moderate AS. Although sex differences in left ventricular (LV) remodeling and outcome are well described in severe AS, it has not been evaluated in moderate AS. Methods In this retrospective, multicenter study, patients with a first diagnosis of moderate AS diagnosed between 2001 and 2019 were identified. Clinical and echocardiographic parameters were recorded at baseline and compared between men and women. Patients were followed up for the primary endpoint of all-cause mortality with censoring at the time of aortic valve replacement. Results A total of 1895 patients with moderate AS (age 73 ± 10 years, 52% male) were included. Women showed more concentric hypertrophy and had more pronounced LV diastolic dysfunction than men. During a median follow-up of 34 (13-60) months, 682 (36%) deaths occurred. Men showed significantly higher mortality rates at 3- and 5-year follow-up (30% and 48%, respectively) than women (26% and 39%, respectively) (p = 0.011). On multivariable analysis, male sex remained independently associated with mortality (hazard ratio 1.209; 95% CI: 1.024-1.428; p = 0.025). LV remodeling (according to LV mass index) was associated with worse outcomes (hazard ratio 1.003; CI: 1.001-1.005; p = 0.006), but no association was observed between the interaction of LV mass index and sex with outcomes. Conclusions LV remodeling patterns are different between men and women having moderate AS. Male sex is associated with worse outcomes in patients with medically treated moderate AS. Further studies investigating the management of moderate AS in a sex-specific manner are needed.

Abstract
Background Sodium glucose cotransporter 2 inhibitors (SGLT-2i) are oral hypoglycemic drugs that can reduce the risk of deteriorating heart failure (HF) or cardiovascular death in patients with HF. Although some animal models have shown that SGLT-2i can effectively inhibit reperfusion injury after acute myocardial infarction (AMI), there is no clinical evidence to prove that SGLT-2i can also play a significant role in improving reperfusion injury in patients with AMI. Therefore, PREDOMINACE study enrolled patients with acute anterior large ST-segment elevation myocardial infarction, who are at high risk of developing HF in the future. The aim of this trial is to study the prevention effects of dapagliflozin on early ventricular dysfunction and remodeling in patients with acute anterior ST-segment elevation myocardial infarction (STEMI), and to explore the efficacy and safety of dapagliflozin in the treatment of patients with diabetes and without diabetes after acute anterior STEMI. Methods Within a multi-center, randomized, single-blind, controlled trial we will recruit patients with acute anterior STEMI from the Second Hospital of Tianjin Medical University and Tianjin Chest Hospital, who are randomly divided into intervention group or control group in a 1:1 ratio. The intervention group was given dapagliflozin (10 mg once daily) before primary percutaneous coronary intervention (PPCI) and 30 days after PPCI, while the control group is not given SGLT-2i. The primary endpoint is the impact of dapagliflozin on changes of NT-proBNP levels in 30 days of acute anterior STEMI. Secondary endpoints include changes in echocardiographic left ventricular remodeling parameters (LVESV, LVEDV, EF), and the changes of ECG (Q wave leads 30 days after PPCI/ST-segment elevation leads at baseline,ST-segment decline degree 24 h and 7 days after PPCI). Hospitalization rate due to HF or other causes, incidence of malignant arrhythmias, and all-cause mortality will be assessed as exploratory secondary endpoints. Discussion The PREDOMINACE trial will test dapagliflozin in patients with acute anterior STEMI, regardless of the presence or absence of diabetes. Therefore, the PREDOMINACE trial may support that the effects of SGLT-2i on improving cardiac remodeling, reducing cardiac pre and after load and improving cardiac metabolism are independent of its antidiabetic effects. Results will provide the clinical rationale for SGLT-2i to improve prognosis in patients with AMI.Trial registration: Chinese Clinical Trial Registry. Identifier: ChiCTR2100048157.

Abstract
The approach to the management of mitral valve (MV) disease and heart failure (HF) has dramatically changed over the last decades. It is well recognized that severe mitral regurgitation secondary to ischemic or non-ischemic cardiomyopathy is associated with an excess risk of mortality. Understanding the impact of the surgical treatment modality on mortality outcomes has been difficult due to the broad spectrum of secondary mitral regurgitation (SMR) phenotypes and lack of randomized surgical clinical trials. Over the last 30 years, surgeons have failed to provide compelling evidence to convince the medical community of the need to treat SMR in patients with severe HF. Therefore, the surgical treatment of SMR has never gained uniform acceptance as a significant option among patients suffering from SMR. Recent evidence from randomized trials in a non-surgical eligible patients treated with transcatheter therapies, has provided a new perspective on SMR treatment. Recently published European and American guidelines confirm the key role of percutaneous treatment of SMR and in parallel, these guidelines reinforce the role of mitral valve surgery in patients who require surgical revascularization. Complex mitral valve repair combining subvalvular apparatus repair along with annuloplasty seems to be a promising approach in selected patients in selected centers. Meanwhile, mitral valve replacement has become the preferred surgical strategy in most patients with advanced heart failure and severe LV remodeling or high risk of recurrent mitral regurgitation. In this comprehensive review, we aimed to discuss the role of mitral surgery for SMR in patients with heart failure in the contemporary era and to provide a practical approach for its surgical management.

Abstract
Heart failure is the leading cause of morbidity and mortality worldwide, with ischemic heart disease being one of the most important etiologic factors. Heart failure develops due to ventricular remodeling, which leads to increases in left ventricular end-systolic and end-diastolic volumes. In this prospective observational study, we included 101 patients with first episode of ST-segment elevation myocardial infarction in whom percutaneous coronary intervention was conducted within 12 h and Thrombolysis in Myocardial Infarction III flow was achieved. The aim was to determine which clinical and biochemical parameters can help predict pathologic ventricular remodeling 1 year after myocardial infarction. We created a nomogram based on routinely used blood tests and vital parameters which showed highest correlation with pathologic ventricular remodeling. The nomogram included NTproBNP value 12 h after reperfusion, aspartate transaminase value 12 h after reperfusion, systolic blood pressure value on admission, and culprit coronary artery. We performed ROC analysis which yielded great predictive value of the nomogram. The area under curve was 0.907 (95% CI 0.842-0.973). The nomogram value of -3.54 had 91.4% sensitivity and 74.0% specificity. We believe that this nomogram, once validated, could offer a widely available, low-cost option that would help identify patients at risk of developing pathologic left ventricular remodeling and achieve this at a very early stage of myocardial infarction (12 h after reperfusion has been achieved).

Abstract
Vitamin D is a hormone with both genomic and non-genomic actions. It exerts its activity by binding vitamin D receptor (VDR), which belongs to the superfamily of nuclear receptors and ligand-activated transcription factors. Since VDR has been found in various tissues, it has been estimated that it regulates approximately 3% of the human genome. Several recent studies have shown pleiotropic effects of vitamin D in various processes such as cellular proliferation, differentiation, DNA repair and apoptosis and its involvement in different pathophysiological conditions as inflammation, diabetes mellitus, and anemia. It has been suggested that vitamin D could play an important role in neurodegenerative and cardiovascular disorders. Moderate to strong associations between lower serum vitamin D concentrations and stroke and cardiovascular events have been identified in different analytic approaches, even after controlling for traditional demographic and lifestyle covariates. The mechanisms behind the associations between vitamin D and cerebrovascular and cardiologic profiles have been widely examined both in animal and human studies. Optimization of vitamin D levels in human subjects may improve insulin sensitivity and beta-cell function and lower levels of inflammatory markers. Moreover, it has been demonstrated that altered gene expression of VDR and 1,25D3-membrane-associated rapid response steroid-binding (1,25D3-MARRS) receptor influences the role of vitamin D within neurons and allows them to be more prone to degeneration. This review summarizes the current understanding of the molecular mechanisms underlying vitamin D signaling and the consequences of vitamin D deficiency in neurodegenerative and cardiovascular disorders.

Abstract
Tissue structure in the infarct and remote zone myocardium post-acute myocardial infarction (MI) may offer prognostic information concerning left ventricular remodeling. We aimed to identify or establish a relationship between adverse remodeling (AR) and changes (Δ) in T1, T2 mapping and extracellular volume (ECV) in post MI periods. Fifty-four MI patients underwent 3 Tesla CMR performed 2 weeks (acute phase) and 6 months post-MI. We measured T1 mapping with MOLLI sequences and T2 mapping with TrueFISP sequences. Hematocrit was quantified in scanning time. ECV was performed post-gadolinium enhancement. AR was defined as an increase of ≥ 10% in left ventricular end-diastolic volume in 6 months. In the acute phase post-MI, high T2 relaxation times of the infarct and remote zone myocardium were associated with AR (OR 1.15, p = 0.023 and OR 1.54, p = 0.002, respectively). There was a decrease in T2 relaxation times of the remote zone myocardium at 6 months in patients with AR (42.0 ± 4.0 vs. 39.0 ± 3.5 ms, p < 0.001), while insignificant difference was found in patients without AR. Increased ΔECV (%) and decreased remote ΔT2 values were associated with AR (OR 1.04, p = 0.043 and OR 0.77, p = 0.007, respectively). The diagnostic performance analysis in predicting AR showed that acute-phase remote T2 was similar to that of remote ΔT2 (p = 0.875) but was superior to that of ΔECV (%) (ΔAUC: 0.19 ± 0.09, p = 0.038). In both acute phase and change of 6 months post-MI, the T2 relaxation times in remote myocardium are independently associated with AR, and this suggests higher inflammation in the remote myocardium in the AR group than the other group, even though no significant pathophysiological difference was observed in the healing of the infarct zone between both groups.

Abstract
BACKGROUND Two-dimensional (2D) and three-dimensional (3D) speckle tracking echocardiography (STE) after ST-elevation acute myocardial infarction (STEMI) can predict the prognosis. This study investigated the clinical significance of a serial 3D-STE can predict the prognosis after onset of STEMI.Methods and Results:This study enrolled 272 patients (mean age, 65 years) with first-time STEMI treated with reperfusion therapy. At 24 h after admission, standard 2D echocardiography and 3D full-volume imaging were performed, and 2D-STE and 3D-STE were calculated. Within 1 year, 19 patients who experienced major adverse cardiac events (MACE; cardiac death, heart failure requiring hospitalization) were excluded. Among the 253 patients, 248 were examined with follow-up echocardiography. The patients were followed up for a median of 108 months (interquartile range: 96-129 months). The primary endpoint was the occurrence of a MACE; 45 patients experienced MACEs. Receiver operating characteristic curves and Cox hazard multivariate analysis showed that the 2D-global longitudinal strain (GLS) and 3D-GLS at 1-year indices were significant predictors of MACE. The Kaplan-Meier curve demonstrated that a 3D-GLS of >-13.1 was an independent predictor for MACE (log-rank χ2=165.5, P<0.0001). The deterioration of 3D-GLS at 1 year was a significant prognosticator (log-rank χ2=36.7, P<0.0001). CONCLUSIONS The deterioration of 3D-GLS measured by STE at 1 year after the onset of STEMI is the strongest predictor of long-term prognosis.

Abstract
OBJECTIVES The role of left ventricular (LV) volumes and ejection fraction (EF) in the selection of patients candidates to MitraClip procedure remains matter of debate. To assess the pattern of LV remodeling and its clinical implications after MitraClip procedures, and to evaluate the role of LV ejection fraction (EF) in patient selection. METHODS Complete echocardiography was performed before, at discharge,1,6, and 12-month in 45 patients treated with MitraClip for severe mitral regurgitation (MR) [age 78.2±8.3 yrs, NYHA 3.74±0.44, EF 36.5±12.8%]. From baseline to 6-month reverse and adverse LV-R was defined as ≥15 % decrease and ≥10% increase in LV end-systolic volume, respectively. RESULTS At 6-month, sustained reduction of MR≤2 was observed in all patients, but 2; reverse, adverse and no LV-R occurred in 51% (N=23), 18% (N=8) and 31% (N=14) patients. Baseline LV end-diastolic volume was an independent predictor of reverse LV-R [P=0.004], whereas EF was not. During follow-up (17.5±9.3 months), freedom from the composite endpoint (mortality and hospitalization for heart failure) was observed in 50% of adverse/no LV-R vs. 95.7% of reverse LV-R patients (P=0.006). At Cox analysis, adverse LV-R and adverse/no LV-R were associated with composite endpoint with adjusted hazard ratio of 5.6 (95% CI 1.65-19.00) and 10.08 (95% CI 1.29-78.6), respectively. CONCLUSIONS After MitraClip implantation, sustained adverse or no LV-R occurred in one-in-two patients and was associated with poor prognosis. Large LV volumes may help us to avoid futility of procedure.

Abstract
Ongoing advancements in the treatment of acute myocardial infarction (MI) have significantly decreased MI related mortality. Consequently, the number of patients experiencing post-MI heart failure (HF) has continued to rise. Infarction size and the extent of left ventricular (LV) remodeling are largely determined by the extent of ischemia at the time of myocardial injury. In the setting of MI or acute phase of post-MI LV remodeling, anti-inflammatory drugs including intravenous immunoglobulin (IVIG) and Pentoxifylline have shown potential efficacy in preventing post-MI remodeling in-vitro and in some clinical trials. However, systemic administration of anti-inflammatory drugs are not without their off-target side effects. Herein, we explore the clinical feasibility of targeted myocardial delivery of anti-inflammatory drugs via biodegradable polymers, liposomes, hydrogels, and nano-particle based drug delivery models (NDDM) based on existing pre-clinical and clinical models. We summarize the barriers to clinical application of targeted anti-inflammatory delivery post-MI, including challenges in achieving sufficient retention and distribution, as well as the potential need for multiple dosing. Collectively, we suggest that localized delivery of anti-inflammatory agents to the myocardium using NDDM is a promising approach for successful treatment of ischemic HF. Future studies will be instrumental in determining the most effective target and delivery modalities for orchestrating NDDM-mediated treatment of HF.

Abstract
AIMS Atrial fibrillation (AF) increases the risk of thromboembolism, such as ischaemic stroke or systemic embolism (SE). The aim of this study was to investigate the relationship between left ventricular relative wall thickness (RWT) and the risk of thromboembolism in patients with non-valvular AF. METHODS AND RESULTS The Fushimi AF Registry is a community-based prospective survey of the patients with AF in Japan. Analyses were performed on 3067 non-valvular AF patients, in which RWT values determined by transthoracic echocardiography were available at the baseline. The high-RWT group (RWT above the median) was more often female, older, and had higher systolic blood pressure, CHADS2 and CHA2DS2-VASc scores, as compared with low-RWT group. During the median follow-up period of 1309 days, there was a higher incidence of ischaemic stroke/SE in the high-RWT group [unadjusted hazard ratio (HR), 1.91; 95% confidence interval (CI), 1.42-2.59]. On multivariate Cox regression analysis, including the components of CHA2DS2-VASc score, left atrial diameter, oral anticoagulant prescription at baseline, and type of AF, high RWT was independently associated with ischaemic stroke/SE (adjusted HR, 1.81; 95% CI, 1.34-2.47). Stratified analysis demonstrated no significant interaction for any subgroups. In Kaplan-Meier analysis, ordinal RWT quartiles stratified the incidence of ischaemic stroke/SE. Finally, addition of RWT to CHA2DS2-VASc score increased the performance of risk stratification for the incidence of stroke/SE. CONCLUSION Relative wall thickness was independently associated with ischaemic stroke/SE among Japanese patients with non-valvular AF, suggesting the importance of left ventricular morphology in contributing to adverse outcomes, particularly thromboembolism.

Abstract
Sphingosine-1-phosphate (S1P)/S1P receptor 1 signaling exerts cardioprotective effects including inhibition of myocyte apoptosis. However, little is known about the effect of S1P treatment on myocyte autophagy after myocardial infarction (MI). In the present study, we tested the hypothesis that S1P induces myocyte autophagy through inhibition of the mammalian target of rapamycin (mTOR), leading to improvement of left ventricular (LV) function after MI. Sprague-Dawley rats underwent MI or sham operation. The animals were randomized to receive S1P (50 μg/kg/day, i.p.) or placebo for one week. H9C2 cardiomyocytes cultured in serum- and glucose-deficient medium were treated with or without S1P for 3 h. MI rats exhibited an increase in LV end-diastolic dimension (EDD) and decreases in LV fractional shortening (FS) and the maximal rate of LV pressure rise (+dP/dt). S1P treatment attenuated the increase in LV EDD and decreases in LV FS and +dP/dt. In the MI placebo group, the LC3 II/I ratio, a marker of autophagy, was increased, and increased further by S1P treatment. S1P also enhanced the autophagy-related proteins Atg4b and Atg5 after MI. Similarly, in cultured cardiomyocytes, autophagy was increased under glucose and serum deprivation, and increased further by S1P treatment. The effect of S1P on myocyte autophagy was associated with mTOR inhibition after MI or in cultured cardiomyocytes under glucose and serum deprivation. S1P treatment prevents LV remodeling, enhances myocyte autophagy and inhibits mTOR activity after MI. These findings suggest that S1P treatment induces myocyte autophagy through mTOR inhibition, leading to the attenuation of LV dysfunction after MI.

Abstract
Background In secondary MR, data on left ventricular (LV) remodeling after MitraClip procedure are rare, even this information may impact patient selection. This study investigated changes in LV structure and function by cardiovascular magnetic resonance (CMR) following MitraClip implantation for secondary mitral regurgitation (MR) in order to assess extent and predictors of LV reverse remodeling (LVRR). Methods and Results Twenty-nine patients underwent CMR imaging prior to and six months after MitraClip procedure. LVRR was defined by a decrease of LV end-diastolic volume index (LVEDVi) > 15% compared to baseline. According to the definition of LVRR, 34% of patients displayed LVRR at follow-up CMR. Baseline LV stroke volume index (LVSVi), LV ejection fraction (LVEF), LV circumferential strain and MR volume at baseline were predictors of LVRR at follow-up. At second CMR, we detected an improvement in hemodynamic status as illustrated by an increase in effective LVSVi (28 ± 8 ml/m2 vs. 33 ± 8 ml/m2; p = 0.053) and cardiac index (2.0 ± 0.5 vs. 2.3 ± 0.5 l/min; p = 0.016), while LVEF and LV strain parameters did not change (p > 0.05). Improvements in effective LVSVi were associated with the decrease of MR volume (r = 0.509; p = 0.018) and MR fraction (r = 0.629; p = 0.002) by MitraClip. Conclusions Together, MitraClip implantation is associated with LVRR in one third of patients. Baseline LV function and magnitude of MR are important predictors of LVRR. Improvement of hemodynamic status may be assessed by effective stroke volume index and correlates with the reduction of MR by MitraClip implantation, rather than an increase in LV contractility.

Abstract
OBJECTIVES To explore the relationships between oxygenation signal intensity (SI) with myocardial inflammation and regional left ventricular (LV) remodeling in reperfused acute ST-segment elevation myocardial infarction (STEMI) using oxygenation-sensitive cardiovascular magnetic resonance (OS-CMR). METHODS Thirty-three STEMI patients and 22 age- and sex-matched healthy volunteers underwent CMR. The protocol included cine function, OS imaging, precontrast T1 mapping, T2 mapping, and late gadolinium enhancement (LGE) imaging. A total of 880 LV segments were included for analysis based on the American Heart Association 16-segment model. For validation, 15 pigs (10 myocardial infarction (MI) model animals and 5 controls) received CMR and were sacrificed for immunohistochemical analysis. RESULTS In the patient study, the acute oxygenation SI showed a stepwise rise among remote, salvaged, and infarcted segments compared with healthy myocardium. At convalescence, all oxygenation SI values besides those in infarcted segments with microvascular obstruction decreased to similar levels. Acute oxygenation SI was associated with early myocardial injury (T1: r = 0.38; T2: r = 0.41; all p < 0.05). Segments with higher acute oxygenation SI values exhibited thinner diastolic walls and decreased wall thickening during follow-up. Multivariable regression modeling indicated that acute oxygenation SI (β = 2.66; p < 0.05) independently predicted convalescent segment adverse remodeling (LV wall thinning). In the animal study, alterations in oxygenation SI were correlated with histological inflammatory infiltrates (r = 0.59; p < 0.001). CONCLUSIONS Myocardial oxygenation by OS-CMR could be used as a quantitative imaging biomarker to assess myocardial inflammation and predict convalescent segment adverse remodeling after STEMI. KEY POINTS • Oxygenation signal intensity (SI) may be an imaging biomarker of inflammatory infiltration that could be used to assess the response to anti-inflammatory therapies in the future. • Oxygenation SI early after myocardial infarction (MI) was associated with left ventricular segment injury at acute phase and could predict regional functional recovery and adverse remodeling late after acute MI. • Oxygenation SI demonstrated a stepwise increase among remote, salvaged, and infarcted segments. Infarcted zones with microvascular obstruction demonstrated a higher oxygenation SI than those without. However, the former showed less pronounced changes over time.

Abstract
Background Coronary computed tomography angiography (CCTA) is widely used as a first-line noninvasive modality that frequently exhibits no or nonobstructive coronary artery disease (CAD) in clinical practice, along with abnormal left ventricular (LV) geometry on echocardiography. However, the combined prognostic value of these findings has not been well elucidated. Therefore, we aimed to evaluate the prognostic implications of abnormal LV geometry in individuals with no or nonobstructive CAD. Methods A total of 5806 subjects with no CAD or nonobstructive CAD (luminal narrowing < 50%) on CCTA were included in the study. The major exclusion criteria were structural heart disease and a history of myocardial infarction or coronary revascularization. Abnormal LV geometry on echocardiography was defined as LV mass index > 95 g/m2 in women and > 115 g/m2 in men, and/or relative wall thickness > 0.42. The primary outcome was all-cause mortality. Results A total of 5803 subjects without significant obstructive CAD (age, 56.6 ± 8.87 years; men, 3884 [66.9%]). Of them, 4045 (69.7%) subjects had normal LV geometry and 1758 (30.3%) had abnormal LV geometry respectively. During a mean follow-up of 6.2 ± 1.48 years, 84 (1.44%) subjects died in the study population. Of these, 56 subjects were from the normal LV geometry group (1.24%) and 28 were from the abnormal LV geometry group (2.32%). Subjects with abnormal LV geometry had significantly worse survival rates (log-rank, p < 0.001). After adjustment for confounding factors, abnormal LV geometry was an independent predictor of all-cause mortality (adjusted hazard ratio, 1.64; 95% confidence interval, 1.04–2.58; p = 0.034). Moreover, abnormal LV geometry was significantly worse in survival when classified as those with no CAD (log-rank, p = 0.024) and nonobstructive CAD (Log-rank, p < 0.001). Conclusions Abnormal LV geometry portends a worse prognosis in subjects with no or nonobstructive CAD. These findings suggest that LV geometry assessment can help improve the stratification of individuals with these CCTA findings.

Abstract
BACKGROUND In patients with severe left ventricular (LV) dysfunction requiring coronary artery bypass grafting (CABG), the association between diabetic status and outcomes after surgery, as well as with survival benefit following bilateral internal thoracic artery (ITA) grafting, remain largely unknown.Methods and Results:Patients (n=188; mean [±SD] age 67±9 years) with LV ejection fraction ≤40% who underwent isolated initial CABG were classified into non-diabetic (n=64), non-insulin-dependent diabetic (NIDM; n=74), and insulin-dependent diabetic (IDM; n=50) groups. During follow-up (mean [±SD] 68±47 months), the 5-year survival rate was 84% and 65% among non-diabetic and diabetic patients, respectively (P=0.034). After adjusting for all covariates, both NIDM and IDM were associated with increased mortality, with hazard ratios (HRs) of 1.9 (95% confidence interval [CI] 1.0-3.7; P=0.049) and 2.4 (95% CI 1.2-4.8; P=0.016), respectively. Among non-diabetic patients, there was no difference in the 5-year survival rate between single and bilateral ITA grafting (86% vs. 80%, respectively; P=0.95), whereas bilateral ITA grafting increased survival among diabetic patients (57% vs. 81%; P=0.004). Multivariate analysis revealed that bilateral ITA was significantly associated with a decreased risk of mortality (HR 0.3; 95% CI 0.1-0.8; P=0.024). CONCLUSIONS NIDM and IDM were significantly associated with worse long-term clinical outcome after CABG for severe LV dysfunction. Bilateral ITA grafting has the potential to improve survival in diabetic patients with severe LV dysfunction.

Abstract
Left ventricular remodeling (LVR) after ST-elevation myocardial infarction (STEMI) is generally thought to be an adaptive but compromising phenomenon particularly in patients with diabetes mellitus (DM). However, whether the extent of LVR is associated with poor prognostic outcome with or without DM after STEMI in the modern era of reperfusion therapy has not been elucidated. This was a single-center retrospective observational study. Altogether, 243 patients who were diagnosed as having STEMI between January 2016 and March 2019, and examined with echocardiography at baseline (at the time of index admission) and mid-term (from 6 to 11 months after index admission) follow-up were included and divided into the DM (n = 98) and non-DM groups (n = 145). The primary outcome was major adverse cardiovascular events (MACEs) defined as the composite of all-cause death, heart failure (HF) hospitalization, and non-fatal myocardial infarction. The median follow-up duration was 621 days (interquartile range: 304–963 days). The DM group was significantly increased the rate of MACEs (P = 0.020) and HF hospitalization (P = 0.037) compared with the non-DM group, despite of less LVR. Multivariate Cox regression analyses revealed that the patients with DM after STEMI were significantly associated with MACEs (Hazard ratio [HR] 2.79, 95% confidence interval [CI] 1.20–6.47, P = 0.017) and HF hospitalization (HR 3.62, 95% CI 1.19–11.02, P = 0.023) after controlling known clinical risk factors. LVR were also significantly associated with MACEs (HR 2.44, 95% CI 1.03–5.78, P = 0.044) and HF hospitalization (HR 3.76, 95% CI 1.15–12.32, P = 0.029). The patients with both DM and LVR had worse clinical outcomes including MACEs and HF hospitalization, suggesting that it is particularly critical to minimize LVR after STEMI in patients with DM.

Abstract
PURPOSE Acutely infarcted native T1 (native T1AI) and extracellular volume (ECVAI) could quantify myocardial injury after acute myocardial infarction (AMI). Therefore, we sought to further explore their association with left ventricular (LV) remodeling during follow-up. METHODS 56 ST-segment-elevation MI patients were prospectively recruited and completed acute and 3-month cardiac magnetic resonance scans. T1 mapping, late gadolinium enhancement and cine imaging were performed to measure native T1AI, ECVAI, infarct size and LV global function, respectively. LV remodeling was evaluated as the change in LV end-diastolic volume index (△EDV) at follow-up scan compared with baseline. RESULTS In acute scan, 37 patients (66.07 %) had microvascular obstruction (MVO). The native T1AI did not significantly differ between patients with or without MVO (1482.0 ± 80.6 ms vs. 1469.0 ± 71.6 ms, P = 0.541). However, ECVAI in patients without MVO was lower than that in patients with MVO (49.60 ± 8.57 % vs. 58.53 ± 8.62 %, P = 0.001). The native T1AI only correlated with △EDV in patients without MVO (rmvo- = 0.495, P = 0.031); while ECVAI was associated with △EDV in all patients (rmvo- = 0.665, P = 0.002; rmvo+ = 0.506, P = 0.001; rall patients = 0.570, P < 0.001). Furthermore, ECVAI was independently associated with LV remodeling in multivariable linear regression analysis (β = 0.490, P = 0.002). CONCLUSION As a promising parameter for early risk stratification after AMI, ECVAI is associated with LV remodeling during follow-up; while native T1AI may be feasible when MVO is absent.

Abstract
Inflammatory processes have been identified as key mediators of ischemia-reperfusion injury in ST-segment elevation myocardial infarction (STEMI). They add damage to the myocardium and are associated with clinical adverse events (heart failure and cardiovascular death) and poor myocardial recovery. Colchicine is a well-known alkaloid with potent anti-inflammatory properties. In a proof-of-concept phase II trial, colchicine has been associated with a significant 50% reduction of infarct size (assessed by creatine kinase levels) in comparison to placebo in acute STEMI patients referred for primary percutaneous coronary intervention (PPCI). The Colchicine in STEMI Patients Study (COVERT-MI) is an ongoing confirmative prospective, multicenter, randomized, double-blind trial testing whether a short course oral treatment with colchicine versus placebo decreases myocardial injury in patients presenting with STEMI referred for PPCI. Adult patients, with a first STEMI episode and an initial TIMI flow ≤1, referred for PPCI, will be randomized (n = 194) in a 1:1 ratio to receive an oral bolus of colchicine of 2 mg followed by 0.5 mg b.i.d. treatment during 5 days or matching placebo. The primary endpoint will be the reduction in infarct size as assessed by cardiac magnetic resonance at 5 ± 2 days between both groups. The main secondary endpoints will be tested between groups in hierarchical order with left ventricular ejection fraction at 5 days, microvascular obstruction presence at 5 days, and absolute adverse left ventricular remodeling between 5 days and 3 months. This academic study is being financed by a grant from the French Ministry of Health (PHRCN-16-0357). Results from this study will contribute to a better understanding of the complex pathophysiology underlying myocardial injury after STEMI. The present study describes the rationale, design, and methods of the trial.

Abstract
BACKGROUND AND AIMS Many studies have examined the association between overweight or obesity assessed by body mass index and left ventricular hypertrophy (LVH) in children or adolescents, but only few studies have assessed the relation with abdominal obesity in children. This study aimed to assess the association of abdominal obesity assessed by waist circumference (WC), high blood pressure (BP) and their joint effect on LVH and left ventricular (LV) geometric remodeling in Chinese children. METHODS AND RESULTS Data were from a cross-sectional survey of 1319 Chinese children aged 6-11 years who had undergone cardiac ultrasound. Compared with normal WC, the adjusted odds ratios (ORs) for abdominal obesity were 6.78 (95% confidence interval [CI] 3.77-12.16) for LVH, 2.80 (1.55-5.05) for CR, 5.43 (2.84-10.39) for EH, and 20.05 (4.46-90.08) for CH, respectively. Compared with children with both normal WC and normal BP, the adjusted ORs for those with abdominal obesity and normal BP were 6.98 (3.71-13.10) for LVH, 2.87 (1.47-5.60) for CR, 5.52 (2.70-11.26) for EH, and 15.20 (4.51-78.13) for CH. The adjusted ORs for those with abdominal obesity and high BP were 7.12 (3.27-15.50) for LVH, 4.71 (2.04-10.85) for CR, 7.49 (3.23-17.40) for EH, and 8.65 (1.32-56.89) for CH. The ORs for those with high BP and normal WC were not significant for these cardiac outcomes (P > 0.05). CONCLUSIONS LVH and LV geometric remodeling were associated more strongly with abdominal obesity than with high BP in Chinese children, stressing the need to prevent childhood abdominal obesity for reducing cardiac risk.

Abstract
BACKGROUND Left ventricular false tendons (LVFT) are common structures visualized on transthoracic echocardiography (TTE). The present study tested the hypothesis that LVFT, via a possible 'constraint' mechanism, attenuate left ventricular (LV) remodeling and secondary mitral regurgitation after acute myocardial infarction. METHODS Seventy-one patients admitted to the Coronary Care Unit following an ST-elevation (n = 63) or non-ST-elevation (n = 8) myocardial infarction were analyzed; 29 (41%) had LVFT, and 42 (59%) did not (no-LVFT). All had a TTE and at least 1 follow-up study after revascularization. The χ² analysis, Student's t-test, and Mann Whitney U test were used for the statistical analyses. RESULTS The mean age (64 vs. 66 years), left ventricular ejection fraction (LVEF) (41% vs. 39%), left ventricular end-diastolic diameter (LVEDd) index (23 mm/m² for both), and prevalence of ≥ moderate secondary/functional mitral regurgitation (MR) (17% vs. 14%) were similar between the LVFT and no-LVFT groups. At 1-year follow-up, there was no significant difference in chamber remodeling amongst the LVFT versus no-LVFT group when assessed by: 1) ≥ 10% decrease in the relative LVEF (24% vs. 26%; p = 0.83); 2) ≥ 10% increase in the LVEDd index (41% vs. 38%, p = 0.98); and, 3) ≥ 10% increase in the LV mass index (48% vs. 41%, p = 0.68). There was no difference in the prevalence of ≥ moderate secondary/functional MR (17% vs. 12%, p = 0.77). Outcomes remained similar when stratifying by LVFT morphology or ischemic territory. CONCLUSIONS In patients with mild to moderate LV dysfunction and normal chamber size, LVFT do not affect the development of LV remodeling or secondary/functional MR post-myocardial infarction.

Abstract
OBJECTIVE To assess left ventricular remodeling patterns using cardiac computed tomography (CT) in children with congenital heart disease and correlate these patterns with their clinical course. MATERIALS AND METHODS Left ventricular volume and myocardial mass were quantified in 17 children with congenital heart disease who underwent initial and follow-up end-systolic cardiac CT studies with a mean follow-up duration of 8.4 ± 9.7 months. Based on changes in the indexed left ventricular myocardial mass (LVMi) and left ventricular mass-volume ratio (LVMVR), left ventricular remodeling between the two serial cardiac CT examinations was categorized into one of four patterns: pattern 1, increased LVMi and increased LVMVR; pattern 2, decreased LVMi and decreased LVMVR; pattern 3, increased LVMi and decreased LVMVR; and pattern 4, decreased LVMi and increased LVMVR. Left ventricular remodeling patterns were correlated with unfavorable clinical courses. RESULTS Baseline LVMi and LVMVR were 65.1 ± 37.9 g/m² and 4.0 ± 3.2 g/mL, respectively. LVMi increased in 10 patients and decreased in seven patients. LVMVR increased in seven patients and decreased in 10 patients. Pattern 1 was observed in seven patients, pattern 2 in seven, and pattern 3 in three patients. Unfavorable events were observed in 29% (2/7) of patients with pattern 1 and 67% (2/3) of patients with pattern 3, but no such events occurred in pattern 2 during the follow-up period (4.4 ± 2.7 years). CONCLUSION Left ventricular remodeling patterns can be characterized using cardiac CT in children with congenital heart disease and may be used to predict their clinical course.
