ABSTRACT

Disease risk due to smoking is not limited to smokers only. Passive smoking, exposure to environmental tobacco smoke, is associated with adverse health effects, and it increases the risk of several diseases. This paper summarizes the cardiovascular effects of tobacco smoke and the current data on the effects of environmental tobacco smoke on the development of cardiovascular disease. According to the results of epidemiologic and experimental studies, environmental tobacco smoke has marked harmful effects on the cardiovascular system. It is estimated that it increases the risk of an acute event of coronary heart disease by 25-35%. Even though the number of studies conducted in the work environment is small, there is no reason to assume that the cardiovascular effects of environmental tobacco smoke differ markedly between the home and the workplace. Firm and timely actions are needed to protect people from exposure to environmental tobacco smoke, both in occupational and other environments. Environmental tobacco smoke (ETS) acutely affects peripheral and coronary vascular tone. Whether ETS exerts specific deleterious effects on aortic wave reflection through nicotine exposure, whether they persist after ETS cessation, and whether the smoke environment impairs microvascular function and increases asymmetrical dimethyl-arginine levels are not known. We tested these hypotheses in a randomized, crossover study design in 12 healthy male nonsmokers. The effects of 1 hour of exposure to ETS, as compared with a nontobacco smoke and normal air, on augmentation index corrected for heart rate and skin microvascular hyperemia to local heating were examined. Augmentation index increased both during (P=0.01) and after (P
