Microplastics and nanoplastics (MNPs) have implicated in cardiovascular disease preclinical studies. Our objective is to investigate the relationship between MNPs coronary arteries major adverse cardiac events (MACE) patients with myocardial infarction (MI).We conducted a prospective observational study involving undergoing angiography for MI. Coronary blood samples were analyzed presence of using pyrolysis-gas chromatography-mass spectrometry. A total 142 enrolled, 110 completing 31.5-month follow-up. Among them, 48 (43.6 %) had detectable polystyrene, 79 (71.8 polyethylene, 105 (95.4 polyvinyl chloride (PVC), 68 (61.8 polyamide 66 their blood. PVC concentration was higher who experienced MACE. Furthermore, levels positively associated proinflammatory factors (IL-1β, IL-6, IL-18, TNF-α), odds MACE (OR: 1.090, 95 %CI: 1.032-1.1523, P = 0.002). Notably, each 10-unit increase PVC, there 1.374-fold risk (OR=2.374, 1.366-4.128, Additionally, we collected thrombus from an additional 21 MI patients, finding that thrombi correlated inflammatory markers monocyte/macrophage infiltration.

Lysosomes in mammalian cells are recognized as key digestive organelles, containing a variety of hydrolytic enzymes that enable the processing both endogenous and exogenous substrates. These organelles digest various macromolecules recycle them through autophagy–lysosomal system. Recent research has expanded our understanding lysosomes, identifying not only centers degradation but also crucial regulators nutrient sensing, immunity, secretion, other vital cellular functions. The lysosomal pathway plays significant role vascular regulation is implicated diseases such atherosclerosis. During atherosclerotic plaque formation, macrophages initially engulf large quantities lipoproteins, triggering pathogenic responses include dysfunction, foam cell subsequent atherosclerosis development. Lysosomal along with inefficient apoptotic accumulation modified low-density negatively impacts lesion progression. studies have highlighted dysfunction contributes critically to cell- stage-specific manner. In this review, we discuss mechanisms biogenesis its regulatory lesions. Based on these functions, propose targeting lysosomes could offer novel therapeutic approach for atherosclerosis, shedding light connection between disease progression while offering new insights into potential anti-atherosclerotic strategies.
