Whats the link between smoking and cardiovascular disease?
Smoking is a major cause of atherosclerosis – a buildup of fatty substances in the arteries. Atherosclerosis occurs when the normal lining of the arteries deteriorates, the walls of the arteries thicken and deposits of fat and plaque block the flow of blood through the arteries. In coronary artery disease, the arteries that supply blood to the heart become severely narrowed, decreasing the supply of oxygen-rich blood to the heart, especially during times of increased activity. Extra strain on the heart may result in chest pain (angina pectoris) and other symptoms. Coronary artery disease can lead to a heart attack. In peripheral artery disease, atherosclerosis affects the arteries that carry blood to the arms and legs. As a result, the patient may experience painful cramping of the leg muscles when walking (a condition called intermittent claudication). Peripheral artery disease also increases the risk of stroke.
