Percutaneous Left Atrial Appendage Occlusion Therapy: Past, Present, and Future

Announcing a new article publication for Cardiovascular Innovations and Applications journal.    

Atrial fibrillation (AF), the most common sustained cardiac arrhythmia, is increasing in incidence and prevalence worldwide. AF significantly increases the risk of intracardiac thrombus formation and, if left untreated, ischemic stroke. In patients with nonvalvular AF (NVAF), the left atrial appendage (LAA) has been determined to be the source of thrombus development in 91% to 99% of cases. In this regard, oral anticoagulants (OACs) have become the standard treatment for stroke prevention in most patients with AF; however, OACs are associated with a risk of bleeding complications, and their efficacy depends on optimal patient compliance. Among alternative approaches to embolic stroke prevention, surgical LAA excision for stroke prevention for valvular AF was attempted as early as the late 1940s. LAA excision remains recommended in surgical guidelines for patients with NVAF requiring open-heart coronary bypass or valvular replacement/repair surgeries. However, owing to the traumatic/invasive nature and suboptimal outcomes of conventional surgical LAA intervention, clinical application of this approach is limited in current cardiology practice. Percutaneous LAA occlusion (LAAO) is increasingly being performed as an alternative to OAC for stroke prevention, particularly in patients with elevated bleeding risk.

Substantial progress has been made in percutaneous LAAO therapy since its inception approximately 20 years ago. This article systematically reviews the literature leading to the development of LAAO and the evidence-based clinical experience supporting the application of this treatment strategy for NVAF, with a focus on recently published critical evaluations of US FDA and CE mark approved LAAO devices. Future perspectives regarding knowledge and technology gaps are also discussed, recognizing the many ongoing clinical trials that are likely to be transformative and the critical unanswered questions regarding LAAO therapy.

Mechanisms of Sodium-glucose Cotransporter 2 Inhibitors in Heart Failure

Announcing a new article publication for Cardiovascular Innovations and Applications journal.    Heart failure is an end stage cardiac disease that has been associated with high mortality and rehospitalization rates in previous decades, in spite of standard anti-heart failure therapy, thus posing a major social and economic burden on public health.

Several studies have demonstrated that sodium-glucose cotransporter 2 inhibitors (SGLT2i), anti-hyperglycemic drugs whose function is independent of islet function, have significant positive effects on prognosis and quality of life, by decreasing mortality and readmission rates in patients with heart failure.

To increase general clinicians’ understanding and facilitate the practical application of SGLT2i in the treatment of heart failure, the mechanisms through which SGLT2i alleviate heart failure are reviewed in this article.

Incidence, Predictors and Associations Between In-Hospital Bleeding and Adverse Events in Patients with Acute Coronary Syndrome Above 75 Years of Age

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Bleeding events in patients with acute coronary syndrome (ACS) are associated with poor outcomes. Risk factors and their associations with in-hospital events in older patients with ACS are not fully understood, because older patients with ACS are often excluded from randomized controlled studies.

The authors of this article enrolled 962 patients with ACS above 75 years of age treated at a center between January 2012 and December 2016. The incidence and risk factors for in-hospital bleeding events, as well as their associations with in-hospital adverse events were evaluated.

Bleeding complications were observed in 38 patients (4.1%). The most common bleeding site was the gastrointestinal tract (52.6%). Anemia (P=0.007), renal insufficiency (P=0.019), use of positive inotropic medicines (P=0.006) and elevated leukocyte count (P=0.046) were independent predictors of in-hospital bleeding after adjustment for age, sex, atrial fibrillation history and hypertension history. In-hospital mortality (28.9% vs. 2.4%, P<0.001), stroke (5.3% vs. 0.5%, P<0.001) and the prevalence of heart failure (39.5% vs. 16.3%, P<0.001) were significantly higher in patients with than without bleeding.

The incidence of in-hospital bleeding was 4.1% in patients with ACS above 75 years of age in this cohort. Independent risk factors for in-hospital bleeding events included anemia, renal insufficiency and elevated leucocyte count. Bleeding events were strongly associated with in-hospital adverse events.

Single-Cell RNA Sequencing Maps Immune Cell Heterogeneity in Mice with Allogeneic Cardiac Transplantation

Announcing a new article publication for Cardiovascular Innovations and Applications journal.   Immune cells play important roles in mediating allograft rejection and tolerance after cardiac transplantation. However, immune cell heterogeneity at the single-cell level, and how immune cell states shape transplantation immunity, remain incompletely characterized.

The authors of this article performed single-cell RNA sequencing (scRNA-seq) on immune cells in LNs from a mouse syngeneic and allogeneic cardiac transplantation model. Nine T cell clusters were identified through unsupervised analysis. Pathway enrichment analysis was used to explore the functional differences among cell subpopulations and to characterize the metabolic heterogeneity of T cells.

The transcriptional landscape of immune cells was determined, particularly T cells, and their metabolic transcriptomes in LNs during mouse cardiac transplantation. On the basis of molecular and functional properties, we also identified T cell types associated with transplantation-associated immune processes, including cytotoxic CD8+ T cells, activated conventional CD4+ T cells, and dysfunctional Tregs. The contribution of JunB to the induction of Th17 cell differentiation and restriction of Treg development was further elucidated, and the authors identified that HIF-1a participates in T cell metabolism and function.

The first systematic single-cell analysis of transcriptional variation within the T cell population is presented in this article, providing new insights for the development of novel therapeutic targets for allograft rejection.

Comparison of the Safety and Efficacy of Warfarin Versus Rivaroxaban in Northern Chinese Patients with Different CHA2DS2-VASc Scores

Announcing a new article publication for Cardiovascular Innovations and Applications journal.   This study was aimed at evaluating the safety and efficacy of warfarin versus rivaroxaban in patients with atrial fibrillation (AF) and different CHA2DS2-VASc score subgroups in northern China.

A retrospective cohort study was conducted to evaluate 387 patients with AF who received treatment at an institution between September 2018 and August 2019. The patients were divided into two groups receiving either warfarin (n=194) or rivaroxaban (n=193). Follow-up data were collected, including adherence, bleeding and ischemic stroke events.

The group receiving rivaroxaban showed better adherence than the group receiving warfarin. In the warfarin-treated group, bleeding incidents declined with increasing scores. In the warfarin-treated group, patients with scores of 2–3 had greater adherence and fewer stroke occurrences. The events of bleeding and stroke did not significantly differ in patients in the rivaroxaban-treated group with different scores.

Compared with patients in the warfarin group with different CHA2DS2-VASc scores, those in the rivaroxaban group had greater compliance, and fewer bleeding and stroke events. Regardless of economic considerations, rivaroxaban is preferable for anticoagulative AF treatment in northern Chinese patients.

Coronavirus Disease 2019, Myocardial Injury, and Myocarditis

Announcing a new article publication for Cardiovascular Innovations and Applications journal. After its initial outbreak in 2019, the 2019 novel coronavirus disease (COVID-19) remains a global health concern. COVID-19 is well known for causing severe respiratory pathology, but it can also cause a variety of extra-pulmonary manifestations. Among them, myocardial injury has received substantial attention because it is usually associated with poor prognosis and mortality, thus emphasizing the importance of monitoring and managing myocardial injury in patients with COVID-19. Myocarditis has received attention as a complication of myocardial injury during and after the onset of COVID-19. Here, to aid in clinical decision-making, the authors of this article present a narrative review on COVID-19- associated myocardial injury and myocarditis, discussing clinical evidence, pathogenesis, diagnostic tools, and therapeutic strategies.

Predictive Value of a Combination of the Age, Creatinine and Ejection Fraction (ACEF) Score and Fibrinogen Level in Patients with Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention

Announcing a new article publication for Cardiovascular Innovations and Applications journal. The purpose of this study was to explore whether consideration of FIB levels might improve the predictive value of the ACEF score in patients with ACS.

A total of 290 patients with ACS were enrolled in this study. The clinical characteristics and MACE were recorded. Multivariate logistic regression analysis revealed that the FIB level (odds ratio=7.798, 95%CI, 3.44–17.676, P<0.001) and SYNTAX score (odds ratio=1.034, 95%CI, 1.001–1.069, P=0.041) were independent predictors of MACE. On the basis of the regression coefficient for FIB, the ACEF-FIB was developed. The area under the ROC of the ACEF-FIB scoring system in predicting MACE after PCI was 0.753 (95%CI 0.688–0.817, P<0.001), a value greater than those for the ACEF score, SYNTAX score and Grace score (0.627, 0.637 and 0.570, respectively).

ACEF-FIB had better discrimination ability than the other risk scores, according to ROC curve analysis, net reclassification improvement and integrated discrimination improvement.

Angiography-Derived Fractional Flow Reserve in Coronary Assessment: Current Developments and Future Perspectives

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Coronary physiology assessment is an important factor in guiding myocardial revascularization. A growing body of research highlights the value of using fractional flow reserve, FFR and other pressure-based indicators for functional assessment of stable coronary stenoses. Invasive functional coronary assessment techniques have evolved from intracoronary wire-based to wire-free approaches as a result of technological advancements. In addition, several software programs on the market have been thoroughly investigated and validated against invasive FFR, and have shown good accuracy and correlation. However, use of FFR remains modest.

This article provides an overview of angiography-based FFR solutions and compares their technologies. Additionally, a systematic scoping review was performed to understand the research landscape in wire-free coronary physiology assessment, to complement the narratives of existing FFR trials on wire-free FFR. Furthermore, future developments and strategies that could expand the use of wire-free computed coronary functional assessment in the Asia Pacific region are discussed.

Integration Analysis of Epigenetic-related m 6A-SNPs Associated with Atrial Fibrillation

Announcing a new article publication for Cardiovascular Innovations and Applications journal.   Numerous single nucleotide polymorphisms (SNPs) have been identified as genetic contributors to atrial fibrillation (AF). The aim of this study was to investigate the effects of genome-wide N6-methyladenosine (m6A)-SNPs on AF.

m6A-SNPs were identified by analysis of raw data from published AF GWAS datasets and the list of m6A-SNPs from the m6AVar database. Expression quantitative trait loci (eQTL) analysis was conducted to evaluate the effects of m6A-SNPs on gene expression. The expression of linked genes was validated in three independent AF-associated gene expression datasets (GSE14975, GSE108660 and GSE2240).

A total of 1429 (6.2%) unique m6A-SNPs that were significantly associated with AF were identified. Seventeen m6A-SNPs in 14 genes reached genome-wide significance. Eight m6A-SNPs demonstrated eQTL signals. Four m6A-SNPs (rs383692, rs3211105, rs1061259 and rs1152582) exhibited strong cis-eQTL signals associated with the gene expression levels of SMIM8, JMJD1C and SYNE2. SYNE2 and SMIM8 had differential gene expression levels between the AF and sinus rhythm groups. In addition, SYNE2 expression was uniformly downregulated in AF samples compared with normal control samples in the three datasets.

The results provide the first demonstration that m6A-SNPs are strongly associated with AF, and extend understanding of m6A modification as a potential biological pathway underlying AF.
