Air pollution is a major risk factor for developing heart and blood vessel diseases, such as heart disease, strokes, and blood clots. Experts discussed this at the CSI conference. Prof Satyendra Tewari from Sanjay Gandhi Post Graduate Institute of Medical Sciences explained that tiny particles in polluted air can enter the bloodstream when we breathe. Long-term exposure can harm the blood vessels, making them narrower and harder. This can increase blood pressure, cause blood clots, and disrupt the heart's normal rhythm, which could lead to a heart attack, stroke, or heart failure. Prof André Ng, the new President of the British Cardiovascular Society, mentioned that in the UK, they are working to prevent about 50,000 new heart disease cases by reducing air pollution by 2035.
