Aerosol generated from vaping devices likely impairs blood vessels’ ability to function comparable to traditional cigarette smoke, according to preliminary research in rats presented at the American Heart Association’s Basic Cardiovascular Sciences Scientific Sessions 2021. The virtual meeting, Aug. 23-25, offers the latest research on basic and translational cardiovascular science.
Vaping, or the use of e-cigarettes, is often promoted as a less harmful alternative to smoking traditional cigarettes. E-cigarettes contain a cartridge with a liquid containing nicotine that generates an aerosol that is inhaled, like smoking a cigarette. Despite the popularity of these devices, knowledge is still limited about the impact of the aerosols from e-cigarettes, heated tobacco products and newer, coil-less, ultrasonic vaping devices on cardiovascular function.
“When you inhale a suspension of particles or a mist, whether it is from tobacco or marijuana, whether it’s smoke or aerosol, it all has the same effect,” said Matthew L. Springer, Ph.D., senior author of the study and a professor of medicine at the University of California, San Francisco School of Medicine. “Our research reinforces the previous findings that vaping is not without harm, and it underscores the importance of counseling patients about the risks of vaping because it does affect cardiovascular function.”
