New information coming from the University of Louisville is showing that two common chemical bases in e-device juices, propylene glycol and vegetable glycerin, could cause real problems for our hearts. In this study, mice were given an acute exposure to e-device aerosols, traditional cigarette smoke, and nicotine-free cigarettes. Despite only being exposed to it for a short period of time, traditional cigarette smoke and e-device aerosol were shown to quickly slow down the mice’s heart rates. This study confirmed what others had done in the past– aerosols release formaldehyde, acrolein, and acetaldehyde- all of which are linked to cardiovascular and pulmonary disease. Acrolein was found to cause the mice’s blood pressure to increase before their heart rates slowed down.
Sometimes a slowed heart rate is not a concern in healthy adults, but it can be worrisome for older adults or those with pre-existing heart conditions. With the presence of these ingredients that have been shown to cause heart problems, the researchers of this study suggested that e-devices may increase a person’s risk of heart disease.
