Air pollution causes 25% of heart-related deaths every year in the world, according to cardiologists.
At a seminar organised at the Heart and Vascular Centre of Chattogram Metropolitan Hospital on Thursday on the occasion of World Hat Day, cardiologists said that unplanned urbanisation of developing countries, extensive expansion of industrial factories, excess carbon emissions etc are causing excessive pollution.
Doctors said air pollution causes blockage of blood flow in arteries and veins, which causes hypertension. It increases the risk of heart disease because harmful ultraviolet rays absorb vitamin D from the sun and the lack of vitamin D increases the risk of heart disease. High levels of air pollution can cause blood clots in the heart and heart blockages. Air pollution increases blood pressure, causes weight gain, and constricts blood vessels.
The speakers also said the heart is the only organ that one can hear and feel. It is the first and last sign of life. They urged all to take care of their hearts to the best of their abilities, saying that everyone should encourage family members, friends and loved ones to take care of their heart.
From the hospital, Dr Mujibul Haque, acting managing director; Dr Sarwar Kamal, chief cardiovascular surgeon; Dr Abdul Motalib, chief cardiologist; Sohail Himika, cardiologist; Dr Kawsar Alam, director; MA Hashem, assistant professor and lab director; Dr Irfan Chowdhury, chief coordinator of Heart and Vascular Centre; and Dr GM Maruf, senior medical officer, were present at the seminar.
