Heart Disease and Stroke
- Cigarette smoking causes coronary heart disease, the leading cause of death in the United States. Cigarette smokers are 2–4 times more likely to develop coronary heart disease than nonsmokers.
- Cigarette smoking approximately doubles a person's risk for stroke.
- Cigarette smoking causes reduced circulation by narrowing the blood vessels (arteries). People who smoke have a much greater risk of developing peripheral vascular disease than nonsmokers.
- Smoking causes abdominal aortic aneurysm.
- Secondhand smoke exposure causes heart disease and lung cancer in nonsmoking adults.
- Nonsmokers who are exposed to secondhand smoke at home or work increase their heart disease risk by 25–30% and their lung cancer risk by 20–30%.
- Breathing secondhand smoke has immediate harmful effects on the cardiovascular system that can increase the risk of heart attack. People who already have heart disease are at especially high risk.
