This chapter reviews the epidemiology of smoking-induced cardiovascular disease (CVD) and the mechanisms by which tobacco smoke is thought to cause CVD. The discussion includes use of biomarkers to diagnose smoking-induced CVD and treatment implications of the pathophysiology of the disease. The link between secondhand smoke and CVD has been reviewed in the 2006 report of the Surgeon General, The Health Consequences of Involuntary Exposure to Tobacco Smoke (U.S. Department of Health and Human Services [USDHHS] 2006), so discussion of secondhand smoke in this report is limited.
