Mitochondria represent pivotal cellular organelles endowed with multifaceted functionalities encompassing cellular respiration, metabolic processes, calcium turnover, and the regulation of apoptosis, primarily through the generation of reactive oxygen species (ROS). Perturbations in mitochondrial dynamics have been intricately linked to the etiology of numerous cardiovascular pathologies, such as heart failure, ischemic heart disease, and various cardiomyopathies. Notably, recent attention has been directed towards the detrimental impact of micro- and nanoplastic pollution on mitochondrial integrity, an area underscored by a paucity of comprehensive investigations. Given the escalating prevalence of plastic particle contamination and the concomitant burden of cardiovascular disease in aging populations, understanding the interplay between mitochondria within the cardiovascular system and micro- and nanoplastic pollution assumes paramount importance. This review endeavors to elucidate the current albeit limited comprehension surrounding this complex interplay. Key words Mitochondria, Nanoplastics, Microplastics, Cardiovascular system, Endothelial function, Oxidative phosphorylation.
