What is atherosclerosis? What is the relationship between smoking and heart disease?

Arteriosclerosis, usually described in the arteries as calcification, occurs when the natural material that exists along the arterial walls is eroded, the arteries’ walls thicken, and accumulate their collections of fats, causing narrowing (or blockage) of the veins. Coronary heart disease is a kind of atherosclerosis. In coronary heart disease, the veins that provide blood to the heart are serious, which reduce the flow of oxygen -rich blood to the heart – especially in times of serious effort. Increased pressure on the heart can lead to chest pain (angina – angina) and other symptoms. What is the relationship between smoking and heart disease? Smoking is an important factor for atherosclerosis. The nicotine in smoke causes, among other things: reducing oxygen to the heart. High blood pressure and heart rate. Increased blood clotting. The cells that lay the walls of the coronary arteries and other blood vessels are damaged, leading to atherosclerosis and heart disease.
