Bone fracture is associated with incident myocardial infarction in long-term follow-up.

Background: The association between bone fracture and cardiovascular diseases is examined in this study. While basic research has established a connection between fractures and heart attacks through the linkage between bones and arteries, population studies have not provided clear evidence. The aim of the present study is to investigate the association between bone fracture and the occurrence of myocardial infarction in a natural population during long-term follow-up.

Transcription factor triggers the SPRY1-NF-κB pathway to maintain testicular immune homeostasis and male fertility.

Bacterial or viral infections, such as , mumps virus, herpes simplex virus, and Zika virus, destroy immune homeostasis of the testes, leading to spermatogenesis disorder and infertility. Of note, recent research shows that SARS-CoV-2 can infect male gonads and destroy Sertoli and Leydig cells, leading to male reproductive dysfunction. Due to the many side effects associated with antibiotic therapy, finding alternative treatments for inflammatory injury remains critical.

MiRNA-122-5p inhibitor abolishes angiotensin II-mediated loss of autophagy and promotion of apoptosis in rat cardiofibroblasts by modulation of the apelin-AMPK-mTOR signaling.

MicroRNAs (miRNAs) have emerged as essential regulators that could have pivotal roles in cardiac homeostasis and pathological remodeling of various cardiovascular diseases. We previously demonstrated that miRNA-122-5p overexpression exacerbated the process of vascular hypertrophy, fibrosis, and dysfunction in hypertensive rats and rat aortic adventitial fibroblasts. However, the exact roles and underlying mechanisms of miRNA-122-5p in myocardial fibroblasts remain largely unknown.

Relationship between circulating miRNA-21, atrial fibrosis, and atrial fibrillation in patients with atrial enlargement.

Background: Atrial fibrosis is a landmark of cardiac remodeling to perpetuate atrial fibrillation (AF), and recent studies have indicated that microRNAs (miRNAs) are essential regulators of multiple cardiovascular disease processes. Herein, we aimed to investigate the relationship between circulating microRNA-21 (miR-21), atrial fibrosis, and AF in patients with atrial enlargement.

Methods: A total of 60 persistent AF patients and 60 matched sinus rhythm (SR) controls were enrolled in the study.

Incidence and Outcome of Acute Myocardial Infarction in Patients With Aortic Dissection and Risk Factor Control.

The contradiction of management modality between acute myocardial infarction(AMI) and aortic dissection(AD) may result in clinical catastrophe. Data on risk factors, incidence, and outcome of AD and AMI are limited, and there have been no studies on the long-term outcomes of AMI in patients with AD. So we aimed to investigate long-term outcomes after AMI in patients with AD, and propose a useful diagnostic paradigm.

Elabela prevents angiotensin II-induced apoptosis and inflammation in rat aortic adventitial fibroblasts via the activation of FGF21-ACE2 signaling.

Apoptosis, inflammation, and fibrosis contribute to vascular remodeling and injury. Elabela (ELA) serves as a crucial regulator to maintain vascular function and has been implicated in the pathogenesis of hypertensive vascular remodeling. This study aims to explore regulatory roles and underlying mechanisms of ELA in rat aortic adventitial fibroblasts (AFs) in response to angiotensin II (ATII).

Declined ELABELA plasma levels in hypertension patients with atrial fibrillation: a case control study.

Background: Atrial fibrillation (AF) is a common arrhythmia in patients with hypertension. ELABELA, which has cardioprotective effects, is decreased in the plasma of patients with hypertension and might be associated with AF in the hypertensive population. This study aims to measure the ELABELA plasma levels in hypertension patients with and without AF and to analyse the related factors.

Increased, Decreased, or Stable Left Ventricle Ejection Fraction over Time in a Series of 626 Heart Failure Patients Receiving Medical Treatment.

Background: Ejection fraction (EF) has been used in phenotype analyses and to make treatment decisions regarding heart failure (HF). Thus, EF has become a fundamental part of daily clinical practice.

Objective: This study aims to investigate the characteristics, predictors, and outcomes associated with EF changes in patients with different types of severe HF.

Pulmonary vein isolation guided by moderate ablation index targets combined with strict procedural endpoints for patients with paroxysmal atrial fibrillation.

Introduction: Ablation index (AI)-guided radiofrequency ablation has been increasingly used for the treatment of drug-resistant paroxysmal atrial fibrillation (AF)，but the optimal AI targets remain to be determined. We aimed to examine the efficacy and safety of catheter ablation guided by moderate AI values but more strict procedural endpoints in patients with paroxysmal AF.

Methods: We conducted a retrospective review of a consecutive series of patients who received their first AI-guided ablation for paroxysmal AF from 2017 to 2018.

Does taking an angiotensin inhibitor increase the risk for COVID-19? - a systematic review and meta-analysis.

Because SARS-COV2 entry into cells is dependent on angiotensin converting enzyme 2 (ACE2) and angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) increase ACE2 activity, the safety of ACEI/ARB usage during the coronavirus disease 2019 (COVID-19) pandemic is a controversial topic. To address that issue, we performed a meta-analysis following The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Searches of the Embase, MEDLINE, PubMed, and Cochrane Library databases identified 16 case-control studies examining the effect of ACEI/ARB on the incidence of COVID-19 and its severity.

Cardiovascular complications of SARS-CoV-2 infection (COVID-19): a systematic review and meta-analysis.

Coronavirus Disease 2019 (COVID-19) originated in Wuhan, China in December 2019 and rapidly spread worldwide. Herein, we conducted a systematic review and meta-analysis to find the association between COVID-19 and cardiovascular complications. We conducted a systematic literature search of the PubMed and Embase databases from 01 December 2019 to 30 November 2020.

Impact of Prior Digestive System Disease on In-Hospital Gastrointestinal Bleeding in Patients with Acute Myocardial Infarction.

Objective: Patients presenting with acute myocardial infarction (AMI) with prior digestive system disease are more likely to suffer from gastrointestinal (GI) bleeding than those without these diseases. However, few articles reported how the different conditions of the digestive tract produced different risks of GI bleeding.

Methods: A single-center study on 7464 patients admitted for AMI from December 2010 to June 2019 in the Beijing Chaoyang Heart Center was retrospectively examined.

Lower Plasma Elabela Levels in Hypertensive Patients With Heart Failure Predict the Occurrence of Major Adverse Cardiac Events: A Preliminary Study.

Elabela, a novel cardiac developmental peptide, has been shown to improve heart dysfunction. However, the roles and correlation of Elabela in predicting adverse cardiac events in hypertensive patients with heart failure (HF) remain largely unclear. To measure plasma levels of Elabela in hypertensive patients with HF and evaluate its prognostic value.

Plasma levels of Elabela are associated with coronary angiographic severity in patients with acute coronary syndrome.

Background: Elabela (ELA) was newly discovered as a novel endogenous ligand of the apelin receptor (APJ) which has demonstrated to be crucial for cardiovascular disease such as myocardial infarction, hypertension and heart failure. Previous experiments have revealed that ELA reduced arterial pressure and exerted positive inotropic effects on the heart. However, the role of plasma ELA levels in patients with acute coronary syndrome (ACS) and its relationship with severity of coronary arteries have not been investigated.

Endothelium-specific endothelin-1 expression promotes pro-inflammatory macrophage activation by regulating miR-33/NR4A axis.

The hallmark of atherogenesis is characterized as endothelial dysfunction and subsequent macrophage activation. Although our previous study has demonstrated that endothelin-1 (ET-1) plays an important role in atherogenesis, the underlying mechanism remains deeply investigation. Enhanced atherosclerotic plaques were observed in endothelium-specific ET-1 overexpression ApoE mice (eET-1/ApoE) concomitant with increased secretion of pro-inflammatory adhesion molecules and cytokines.
