Researchers have also found a positive association between e-cigarette use and an increase in cardiovascular risk. Scientists think the nicotine present in e-cigarette liquids is the cause.
According to Medical News Today:
“Nystoriak and colleagues tested 15 different e-cigarette flavorings on human cardiomyocytes derived from induced pluripotent stem cells.
Cardiomyocytes are the cells that make up the heart muscle, and they are responsible for the contractile function of the heart, which enables the organ to pump blood around the body.
The team monitored how each flavoring — when heated and unheated — affected the function of cardiomyocytes.”
THEY FOUND THAT CINNAMALDEHYDE, OR CINNAMON FLAVORING, PREVENTED THE CARDIOMYOCYTES FROM CONTRACTING 24 HOURS AFTER COMING INTO CONTACT WITH THEM, WHILE EUGENOL (CLOVE), CITRONELLOL (FLORAL), AND LIMONENE (CITRUS) CAUSED THE HEART MUSCLE CELLS TO BEAT FASTER.
“THESE EFFECTS [FROM THE CHEMICALS] ARE KIND OF STRIKING BECAUSE IT SUGGESTS THAT IF THIS COMPOUND WAS INTERACTING WITH THE HEART MUSCLE ITSELF, IT COULD DO SOMETHING DIRECTLY TO CHANGE HOW THAT CELL ACTUALLY FUNCTIONS,” SAYS NYSTORIAK.
The researchers found that the liquid flavorings caused the most drastic effects when they were unheated.
