Delhi Pollution Triggers Heart Emergencies: Study Reveals Direct Link

• A new pilot study published in Discover Public Health links rising air pollution directly to cardiovascular emergencies in Delhi.
• Researchers found a "one-day lag" effect: pollution spikes lead to a significant rise in heart-related hospital admissions within 24 hours.
• Every 10-unit AQI increase correlated with a 1.8% jump in cardiovascular events; PM2.5 showed a 2% rise in admissions.
• Delhi patients were younger with urban risk factors like inactivity and poor diet, unlike Shimla patients linked to tobacco and solid fuels.
• The study recommends expanding India's National Outdoor Air and Disease Surveillance (NOADS) to include cardiovascular data.

Why It Matters: Delhi's air pollution directly and immediately triggers heart emergencies, urging expanded health surveillance.
