Special Issue Information

Dear Colleagues, 

Although cardiology has progressed dramatically, cardiovascular diseases (CVDs) and malignant arrhythmias remain the most common cause of death worldwide, and much remains to be accomplished. The next major steps should include more vigorous and widespread prevention as well as the application of the recent remarkable advances in genomics. The best way to avoid cardiovascular diseases (CVDs) and cardiac arrhythmias is to prevent their development. One of the most important risk factors of CVDs is an unhealthy lifestyle. Regular medical screening can reveal warning signs or biomarkers like increased blood pressure, blood glucose, lipid profile, C-reactive protein, and body mass index, which indicates a predisposition to diseases before symptoms manifest. Screenings can improve health outcomes via lifestyle modifications, such as diet, exercise, cold acclimation, or treatment interventions. There is a need to mitigate climate change due to the greenhouse gas emission-associated cardiovascular risk, particularly in vulnerable populations. Recent advancements highlight the potential of naturally derived bio-products with epigenetic properties which offer protection against CVDs and cardiac arrhythmias. To reach the optimal level of protection, a multi-targeted approach directed towards more than one intracellular signaling pathway or cell type is required. One of the most studied targets are mitochondria because of their key involvement in reactive oxygen species (ROS) production facilitating chronic low-grade inflammation that predispose to CVDs and arrhythmias. On the other hand, hydrogen medicine is one of the most promising novel strategies for the prevention and/or treatment of these adverse conditions via molecular hydrogen. "There is still time to share your science’’.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Cardiovascular disorders and the medications used to treat them can affect physiological patterns of behavior. The aim of the present study was to determine whether the dual inhibition of neprilysin and angiotensin II—sacubitril/valsartan (ARNI) can modify anxiety-like behavior in male spontaneously hypertensive rats (SHR). We compared ARNI with two other drugs in the portfolio of heart failure treatment, captopril and ivabradine. Six groups (n = 13) of 12-week-old rats were treated for six weeks: control (Wistar rats), control + ARNI, SHR, SHR + ARNI, SHR + captopril, and SHR + ivabradine. The elevated plus maze test, the open field test, and the light–dark box test were used to determine anxiety-like behavior. SHRs exhibited higher systolic blood pressure (SBP), heart rate (HR), left ventricular weight (LVW), and hydroxyproline concentration (LVHP) but displayed a reduced level of anxiety-like behavior in comparison to controls. ARNI reduced SBP, HR, and LVW but had no significant effect on the level of anxiety in SHR, and similar results were achieved by captopril and ivabradine. Additionally, correlation analysis indicated that anxiety-like behavior in Wistar rats or SHR, either with or without cardiovascular therapy, was independent of SBP, HR, LVW, or LVHP. The level of anxiety-like behavior can, therefore, be considered part of the inherent neurobehavioral traits unrelated to fundamental hemodynamic or structural cardiovascular parameters. Full article
