Special Issue Information
Dear Colleagues,
Cardiovascular diseases (CVDs) are one of the leading causes of death, responsible for a third of all deaths globally. The heart is the most metabolically active organ as cardiac muscle contraction and relaxation both highly demand ATP production, which is mainly supplied by oxidative phosphorylation in the mitochondria. However, mitochondria serve roles beyond ATP biosynthesis, including the regulation of redox homeostasis, reactive oxygen species (ROS) signaling, cell death, ion homeostasis and inflammation.
Mitochondrial dysfunction has been recognized as pivotal in the pathogenesis and progression of CVDs, such as atherosclerosis, cardiac hypertrophy, myocardial infarction, ischemia–reperfusion injury and heart failure. This dysfunction encompasses defects in mitochondrial respiratory chain function, metabolic substrate utilization, mitochondrial network organization and dynamics, mitophagy, biogenesis and redox signaling. Moreover, impaired mitochondrial ROS handling alters cellular ion homeostasis, critical for cardiac electrophysiology, thereby increasing the propensity for cardiac arrhythmias. A deeper understanding of mitochondria and their role in the molecular mechanisms underlying CVDs is imperative for the development of therapeutic strategies.
This Special Issue will focus on the role of mitochondrial dysfunction in the development and progression of CVDs.

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. Life 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.
