Smoking is a major cause of cardiovascular disease (CVD) and causes approximately one of every four deaths from CVD. According to World Health Organization data, smoking determines 10% of all CVDs. Tobacco smoking usage causes approximately 6 million death per year throughout the world, in the United States almost 500,000 deaths can be attributed to smoking and about 10% of these deaths are caused from second-hand smoke exposure. Epidemiologic studies have supported the assumption that cigarette smoking increases the incidence of myocardial infarction and fatal coronary artery diseases. Chemicals in cigarette smoke cause the cells that line blood vessels to become swollen and inflamed. This can narrow the blood vessels and can lead to many cardiovascular conditions.
Atherosclerosis, in which arteries narrow and become less flexible, occurs when fat, cholesterol, and other substances in the blood form plaque that builds up in the walls of arteries. The opening inside the arteries narrows as plaque builds up, and blood can no longer flow properly to various parts of the body. Smoking increases the formation of plaque in blood vessels.
Coronary Heart Disease occurs when arteries that carry blood to the heart muscle are narrowed by plaque or blocked by clots. Chemicals in cigarette smoke cause the blood to thicken and form clots inside veins and arteries. Blockage from a clot can lead to a heart attack and sudden death.
Stroke is a loss of brain function caused when blood flow within the brain is interrupted. Strokes can cause permanent brain damage and death. Smoking increases the risk for strokes. Deaths from strokes are more likely among smokers than among former smokers or people who have never smoked.
Peripheral Arterial Disease (PAD) and peripheral vascular disease occur when blood vessels become narrower and the flow of blood to arms, legs, hands and feet is reduced. Cells and tissue are deprived of needed oxygen when blood flow is reduced. In extreme cases, an infected limb must be removed. Smoking is the most common preventable cause of PAD.
Abdominal Aortic Aneurysm is a bulge or weakened area that occurs in the portion of the aorta that is in the abdomen. The aorta is the main artery that carries oxygen-rich blood throughout the body. Smoking is a known cause of early damage to the abdominal aorta, which can lead to an aneurysm. A ruptured abdominal aortic aneurysm is life-threatening; almost all deaths from abdominal aortic aneurysms are caused by smoking. Women smokers have a higher risk of dying from an aortic aneurysm than men who smoke. Autopsies have shown early narrowing of the abdominal aorta in young adults who smoked as adolescents.
