Carbon monoxide is an air pollutant. It is found in cigarette smoke and emissions from motor vehicles, industrial processes, and poorly ventilated combustion sources.
Carbon monoxide could manifest its toxic effects on the heart and blood vessels in two ways, either by causing acute, short-term effects on oxygen delivery or by contributing to the development of cardiovascular diseases such as atherosclerosis. Atherosclerosis is a progressive disease characterized by thickening of the arteries and a buildup of deposits of fat, cholesterol, cells, and connective tissue in the inner lining of the blood vessels.
