Deep dives
The Impact of Air Pollution on Heart Health
Air pollution significantly affects cardiovascular health through various mechanisms. Fine and ultrafine particulate matter (PM2.5 and PM10) can penetrate deep into the lungs, eliciting inflammatory responses that lead to heart disease. Notably, about 80% of premature deaths associated with air pollution are due to heart-related issues. Dr. Aruni Bhatnagar emphasizes the need to understand these mechanisms, illustrating that even if pollution appears minimal, the invisible particles can have dire health consequences.
