EC smoking, similar to TC smoking, may act at a central level to cause a uniform increase in sympathetic nerve traffic to blood vessels, skin and the heart. Alterations in sympathetic drive are paralleled by an increase in blood pressure and heart rate, reflecting a systemic hemodynamic response to smoking of both types of cigarettes. These unfavorable effects of ECs mimicking those by TCs may chronically lead to increased risk of cardiovascular events. BP, blood pressure; CV, cardiovascular; EC, electronic cigarette; HR, heart rate; TC, tobacco cigarette.
