Special Issue Information

Dear Colleagues,

Cardiovascular disease (CVD) refers to a wide variety of pathogenic conditions that affect the heart and vessels, including congenital heart disease, coronary heart disease, rheumatic heart disease, cardiomyopathy, cardiac arrhythmias, essential hypertension, heart failure, and stroke. CHD remains the number one cause of death worldwide, accounting for one third of global deaths and, consequently, a tremendous burden for human healthcare systems. It is caused by both genetic and environmental risk factors; therefore, a comprehensive understanding of the etiologies and mechanisms behind CVD could improve early diagnosis and personalized treatment in CVD. This Special Issue will focus on etiologies, pathogenesis, and diagnostic, therapeutic, and preventive modalities in CVD. Research articles focusing on newly discovered molecular causes, pathogeneses, diagnostics, and medical management strategies in patients with CVD are strongly encouraged.

I hope that this Special Issue will provide novel insights into diagnosis, prophylaxis, and treatment in CVD. Authors can submit original research articles, reviews, case reports, and guidelines covering any aspect of this topic.

Background/Objectives: Biological aging phenotypes in coronary artery disease (CAD) include coronary atherosclerosis, vascular aging, and endothelial dysfunction. The aim of the present study was to investigate the potential links between aging phenotypes, regulatory immune cells, and features of the thymus in patients with CAD. Methods: A single-center, cross-sectional, comparative study was conducted. Patients were stratified according to the severity of coronary atherosclerosis: patients with a Gensini score ≥ 65 points and patients with a Gensini score < 65 points. Peripheral blood and thymus biopsy were obtained. Imaging flow cytometry, ELISA, and immunohistochemical analysis were used for analysis. Results: Thymic morphology ranged from total fatty involution to a preserved structure of the thymus (20–80% area in 31% of obtained samples) but was not associated with the severity of atherosclerosis. Meanwhile, patients with a Gensini score ≥ 65 had impaired thymus cellular composition compared to patients with a Gensini score < 65 points; increased frequency of CD8+ T lymphocytes and NK cells; and decreased frequency of CD4 + CD8+ T lymphocytes. In peripheral blood, the main determinants of a Gensini score ≥ 65 points were low absolute counts of eMDSCs and CD25low Tregs with FoxP3 nuclear translocation, while advanced vascular aging was associated with elevated eMDSC absolute counts. Advanced coronary atherosclerosis was also associated with decreased numbers of endothelial progenitor cells in circulation. Conclusions: Thymus dysfunction accompanies CAD progression and is manifested in changes in cellular composition rather than morphology. In CAD patients, MDSC and Treg lymphocytes are equally involved in the progression of coronary atherosclerosis, which is aggravated by the decreased regulatory potential of the endothelium. Vascular aging represents a distinct phenotype of biological aging in CAD patients, characterized by the expansion of eMDSCs. Full article

Background/Objectives: Dilated cardiomyopathy (DCM), defined as dilation and contractile dysfunction of the left or both cardiac ventricles, remains the most common category of primary myocardial disease worldwide. It is the most prevalent cause of chronic heart failure and the most common indication for cardiac transplantation in young subjects. Accumulating evidence increasingly highlights the substantial genetic defects underlying DCM. Nevertheless, the genetic ingredients accountable for DCM in a major percentage of patients remain indefinite. Methods: A multigenerational pedigree suffering from DCM and a total of 276 healthy volunteers employed as controls were recruited from the Chinese Han-ethnicity population. A whole-exome sequencing (WES) assay followed by a Sanger sequencing analysis of the genomic DNAs from the available family members was implemented. Functional characterization of the identified genetic variant was completed by dual-luciferase analysis. Results: A new heterozygous variation in the ETS1 (erythroblast transformation-specific 1) gene, NM_005238.4:c.447T>G;p.(Tyr149*), was identified by WES and validated by Sanger sequencing analysis to co-segregate with DCM in the whole DCM family. This nonsense ETS1 variant was not found in 276 control subjects. Functional examination elucidated that Tyr149*-mutant ETS1 lost the ability to transactivate its downstream target genes CLDN5 (claudin 5) and ALK1 (activin receptor-like kinase 1), two genes crucial for cardiovascular embryonic development and postnatal structural remodeling. Conclusions: The present investigation reveals ETS1 as a new gene predisposed to human DCM and indicates ETS1 haploinsufficiency as an alternative molecular pathogenesis underlying DCM, providing a potential molecular target for genetic counseling and early diagnosis as well as personalized prophylaxis of DCM.
