Abstract (original English)

Cardiovascular diseases (CVDs) represent a profound challenge with inflammation playing a significant role in their pathophysiology. Extracellular vesicles (EVs), which are membranous structures encapsulated by a lipid bilayer, are essential for intercellular communication by facilitating the transport of specific bioactive molecules, including microRNAs, proteins, and lipids. Emerging evidence suggests that the regulatory mechanisms governing cardiac resident cells are influenced by EVs, which function as messengers in intercellular communication and thereby contribute to the advancement of CVDs. In this review, we discuss the multifaceted biological functions of EVs and their involvement in the pathogenesis of various CVDs, encompassing myocardial infarction, ischemia-reperfusion injury, heart failure, atherosclerosis, myocarditis, cardiomyopathy, and aneurysm. Furthermore, we summarize the recent advancements in utilizing EVs as non-invasive biomarkers and in cell-free therapy based on EVs for the diagnosis and treatment of CVDs. Future research should investigate effective techniques for the isolation and purification of EVs from body fluids, while also exploring the pathways for the clinical translation of therapy based on EVs. Additionally, it is imperative to identify appropriate EV-miRNA profiles or combinations present in the circulation of patients, which could serve
