Fri Nov 15 07:44:15 UTC 2024: ## Delhi Chokes on Pollution: Cardiovascular and Respiratory Health at Risk

**New Delhi, India:** Delhi and surrounding regions are facing a severe air pollution crisis, with the Air Quality Index (AQI) soaring to alarming levels of 300-400 and even exceeding 500. Experts warn that this hazardous air quality poses a significant threat to public health, especially in winter when vehicular emissions, industrial pollutants, and stubble burning combine to create dense smog.

The World Heart Federation’s (WHF) World Heart Report 2024 highlights the critical link between air pollution and cardiovascular disease (CVD). India, already burdened with a high prevalence of CVDs, faces an even more challenging situation due to its polluted environment. According to the report, air pollution exacerbates all major CVDs, including ischemic heart disease (IHD) and stroke, which together account for millions of deaths globally.

**Cardiovascular Impact:**

Dr. Faraz Ahmed Farooqui, Consultant- Cardiology, PSRI Hospital, explains that long-term exposure to air pollution triggers endothelial dysfunction and oxidative stress, leading to increased risk of heart disease. He points to the alarming rise in cases of coronary artery disease, stroke, and heart failure in polluted areas. Air pollution not only increases blood pressure but also inflames blood vessels, accelerating atherosclerosis and increasing the risk of heart attacks and strokes.

Dr. Rajendra Patil, Consultant – Cardiology, Jupiter Hospital, emphasizes the impact of agricultural residue burning in North India, which releases particulate matter (PM2.5 and PM10) and worsens cardiovascular health. He also highlights the burden of household air pollution from biomass cooking, particularly affecting women and children in rural areas, leading to hypertension and increased risk of heart disease.

**Respiratory Concerns:**

Dr. Praveen Gupta, Principal Director & Chief of Neurology, Fortis Hospital, warns that pollution exacerbates respiratory problems like COPD and asthma, increases the risk of heart disease and stroke, and contributes to cognitive impairment and dementia. Air pollution also negatively impacts mental health, leading to anxiety, depression, and cognitive decline.

**Call to Action:**

Experts urge immediate action to address the air pollution crisis and protect public health. They advocate for stronger environmental policies at local and national levels and highlight the need to promote cleaner cooking alternatives in rural areas. Individuals can also contribute by using public transport, reducing reliance on wood and coal for cooking, maintaining their vehicles, and avoiding high-pollution zones.

**Key Takeaways:**

* Delhi and surrounding regions are facing a severe air pollution crisis with alarming AQI levels.
* Air pollution poses a significant threat to public health, particularly to cardiovascular and respiratory systems.
* The World Heart Report 2024 highlights the critical link between air pollution and CVD.
* Experts urge immediate action to address air pollution, including stronger environmental policies and promotion of cleaner cooking alternatives.

This crisis demands urgent attention and collaborative efforts from government, institutions, and individuals to protect the health of our citizens.
