To identify and synthesize the plausible pathophysiological mechanisms through which inhalation of ambient particulate matter causes cardiovascular morbidity and mortality.
Narrative mechanistic review of toxicological, epidemiological, and physiological literature investigating ambient particulate inhalation and cardiovascular outcomes.
Inhaled particles induce localized pulmonary oxidative stress and inflammation, prompting systemic cytokine release that promotes vascular endothelial dysfunction and hypercoagulability.
Particle interactions with airway receptors perturb autonomic nervous system reflex pathways, triggering heart rate variability alterations and arrhythmic events.
Direct translocation of ultrafine particulate matter across the alveolar membrane into the systemic circulation represents a potential direct driver of vascular damage and thrombosis.

Implication

Review reveals mechanisms linking inhaled particulate matter to cardiovascular dysfunction in exposed populations, highlighting systemic inflammation and autonomic imbalance.
