Key result
Tobacco smoking is a major cause of cardiovascular disease, and exposure to environmental tobacco smoke in never-smokers is associated with a 20-30% excess risk of coronary heart disease.

Reinforces tobacco avoidance in CVD prevention; leaves open precise risk quantification from observational syntheses.
Does tobacco smoking increase the risk of cardiovascular disease, and does smoking cessation reduce this risk?
Tobacco smoking is a major modifiable cause of cardiovascular disease death, and smoking cessation significantly reduces this risk, approaching never-smoker levels within 10 years.
Chen et al. (2002) conducted a review in Cardiovascular disease. Tobacco smoking vs. Never-smokers was evaluated on Cardiovascular disease and coronary heart disease. Tobacco smoking is a major cause of cardiovascular disease, and exposure to environmental tobacco smoke in never-smokers is associated with a 20-30% excess risk of coronary heart disease.
