Studies find cardiovascular effects of cigarettes and e-cigarettes to be strikingly similar

Two related studies, one in humans and the other in rats, found that the cardiovascular effects of cigarettes and e-cigarettes are strikingly similar, and these harmful effects on blood vessel function are likely caused by airway irritation due to inhalation of a foreign substance, rather than a specific component of the cigarette smoke or e-cigarette vapor (aerosol), according to new research published today in the American Heart Association's peer-reviewed journal Arteriosclerosis, Thrombosis and Vascular Biology.
