Compound Heterozygosity for Late-Onset Cardiomyopathy-Causative ALPK3 Coding Variant and Novel Intronic Variant Cause Infantile Hypertrophic Cardiomyopathy
AbstractHypertrophic and dilated cardiomyopathy (HCM, DCM) are leading causes of cardiovascular morbidity and mortality in children. The pseudokinase alpha-protein kinase 3 (ALPK3) plays an essential role in sarcomere organization and cardiomyocyte differentiation.ALPK3 coding mutations are causative of recessively inherited pediatric-onset DCM and HCM with variable expression of facial dysmorphism and skeletal abnormalities and implicated in dominantly inherited adult-onset cardiomyopathy. We now report two variants inALPK3—a coding variant and a novel intronic variant affecting splicing. We demonstrate that compound he...

ASSESS-IE: a Novel Risk Score for Patients with Infective Endocarditis
This study was conducted to establish a new risk model to predict in-hospital and 6-month mortality in IE patients. A total of 1549 adult patients with definite IE admitted to Guangdong Provincial People ’s Hospital (n=1354) or Xiamen Cardiovascular Hospital (n=195) were included. The derivation cohort consisted of 1141 patients. The score was developed using the multivariate stepwise logistic regression analysis for in-hospital death. Bootstrap analysis was used for validation. Discrimination and calibration were evaluated by the receiver operating characteristic curve and the Hosmer –Lemeshow goodness-of-fit test. Si...

Slow-Reflow and Prognosis in Patients with High Parathyroid Hormone Levels Undergoing Primary Percutaneous Coronary Intervention for Acute ST-Segment Elevation Myocardial Infarction
AbstractWe aimed to evaluate the correlation among serum parathyroid hormone (PTH) and slow-reflow during primary percutaneous coronary intervention (PCI) and prognosis in patients with ST-segment elevation myocardial infarction (STEMI). A total of 262 patients were enrolled and divided into a slow-reflow group (n = 61) and a control group (n = 201). PTH was an independent risk factor for slow-reflow (P <  0.05), and the regression model had good discrimination and calibration. ROC curve analysis showed that PTH (≥ 63.65 pg/ml) had a predictive value for slow-reflow (P <  0.001). During the 1-year...

The Fragmented QRS Complex in Lead V1: Time for an Update of the Athlete ’s ECG?
AbstractDifferentiating between ECG patterns related to athletes' heart remodeling and pathological findings is a challenge in sports cardiology. As the significance of fragmented complex in athletes remains uncertain, this study aimed to assess the presence of fragmented QRS in lead V1 (fQRSV1) among young athletes and its association with heart adaptations and arrhythmias. Young athletes referred for annual pre-participation screening receiving a maximal exercise testing and transthoracic echocardiography from January 2015 to March 2021 were included. The study included 684 young athletes. The prevalence of fQRSV1 was 33...

CREB1 Silencing Protects Against Inflammatory Response in Rats with Deep Vein Thrombosis Through Reducing RPL9 Expression and Blocking NF- κB Signaling
AbstractApoptosis and inflammation of vascular endothelial cells (VECs) are the most important causes of deep vein thrombosis (DVT). cAMP response element binding protein 1 (CREB1) encodes a transcription factor that binds as a homodimer to the cAMP-responsive element and can promote inflammation. CREB1 is found to be upregulated in the plasma of patients with venous thromboembolism. However, the biological functions of CREB1 in DVT remain unknown. We evaluated the effect of CREB1 in a rat model of inferior vena cava (IVA) stenosis-induced DVT. IVC stenosis resulted in stable thrombus, inflammatory response and CREB1 upreg...

Enhanced Levels of Adiposity, Stretch and Fibrosis Markers in Patients with Coexistent Heart Failure and Atrial Fibrillation
AbstractThe coexistence of heart failure (HF) and atrial fibrillation (AF) worsens the prognosis of patients. We aimed to study the inflammation, metabolism, adiposity, and fibrosis markers on epicardial and subcutaneous fat and blood, and their relationship with HF and AF. Samples from 185 patients undergoing cardiac surgery were collected. Levels of multi-markers on fat biopsies and plasma were analyzed. Patients were grouped by HF or AF presence. Plasma adiposity markers were increased in AF patients, while increased stretch markers correlated with HF. Patients with both AF and HF had higher ANP and GDF-15 levels. After...

Mesenchymal Stem Cell-Derived Exosomes and Their MicroRNAs in Heart Repair and Regeneration
AbstractMesenchymal stem cells (MSCs) can be differentiated into cardiac, endothelial, and smooth muscle cells. Therefore, MSC-based therapeutic approaches have the potential to deal with the aftermaths of cardiac diseases. However, transplanted stem cells rarely survive in damaged myocardium, proposing that paracrine factors other than trans-differentiation may involve in heart regeneration. Apart from cytokines/growth factors, MSCs secret small, single-membrane organelles named exosomes. The MSC-secreted exosomes are enriched in lipids, proteins, nucleic acids, and microRNA (miRNA). There has been an increasing amount of...

Exercise Training Improves Brachial Artery Endothelial Function, but Does Not Alter Inflammatory Biomarkers in Patients with Peripheral Artery Disease: a Systematic Review and Meta-analysis
AbstractThe study aimed to systematically review the effects of exercise training (EX) on brachial artery flow-mediated dilation (FMD) and inflammatory biomarkers in patients with peripheral artery disease (PAD). Five electronic databases were searched: (i) patients with PAD aged  ≥ 18; (ii) structured EX ≥ 2 weeks; (iii) measured brachial artery FMD; and (iv) measured blood inflammatory biomarkers. Eighteen studies met the inclusion criteria. EX increased FMD but had no effect on C-reactive protein, interleukin-6, and tumor necrosis factor-α. Subgroups with mo derate intensity had a greater increase in FMD t...
