E-Cigarettes Not Tied to Risk of Heart Disease in Study

Electronic cigarettes used by smokers who want to kick the habit show no connection to heart disease, according to a study that adds to evidence of health benefits of switching from tobacco to smokeless alternatives.

E-cigarettes, electronic tubes that simulate the effect of smoking by producing nicotine vapor, prompted no adverse effects on cardiac function in the study, researchers from the Athens-based Onassis Cardiac Surgery Center said in a report presented at the European Society of Cardiology annual meeting in Munich today.
