Special Issue Information

Dear Colleagues,

Cardiovascular diseases, which include coronary heart disease, cerebrovascular disease, rheumatic heart disease, peripheral vascular disease, and other conditions, represent the leading cause of death worldwide. Among the top 10 diseases that lead the mortality rate worldwide, stroke and ischemic diseases are included here and are also consequences of hypertension. Since there are several behavioral risk factors for cardiovascular diseases, such as unhealthy diet, physical inactivity, tobacco consumption, and harmful use of alcohol, associated with hypertension, diabetes, and excess weight, the treatment for these pathologies can be very complex. Therefore, a deeper understanding of the disease mechanisms could significantly contribute to more effective treatment and to a reduction in premature deaths from cardiovascular diseases. Animal models are useful as they represent the main strategy for exploring the different mechanisms involved in cardiovascular diseases. Overall, this Special Issue invites you and your colleagues to share your expertise and knowledge by submitting original research articles, systematic reviews, and review articles that report new ideas and recent advances on this topic.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Biomedicines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). 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.

Since cardiac inflammation has been considered an important mechanism involved in heart failure, an anti-inflammatory treatment could control cardiac inflammation and mitigate the worsening of cardiac remodeling. This study evaluated the effects of dexamethasone (DEX) and ramipril treatment on inflammation and cardiac fibrosis in an experimental model of heart failure induced by supravalvular aortic stenosis. Wistar rats (21d) were submitted to an aortic stenosis (AS) protocol. After 21 weeks, an echocardiogram and a maximal exercise test were performed, and after 24 weeks, rats were treated with DEX, ramipril or saline for 14d. The left ventricle (LV) was removed for histological and inflammatory marker analyses. The AS group showed exercise intolerance (−32% vs. Sham), higher relative wall thickness (+63%), collagen deposition and capillary rarefaction, followed by cardiac disfunction. Both treatments were effective in reducing cardiac inflammation, but only DEX attenuated the increased relative wall thickness (−17%) and only ramipril reduced LV fibrosis. In conclusion, both DEX and ramipril decreased cardiac inflammatory markers, which probably contributed to the reduced cardiac fibrosis and relative wall thickness; however, treated AS rats did not show any improvement in cardiac function. Despite the complex pharmacological treatment of heart failure, treatment with an anti-inflammatory could delay the patient’s poor prognosis. Full article
