Flavoured additives in e-cigarettes can cause heart damage

ANI  |  Washington D.C. [USA] 

Flavoured additives used in can impair function and lead to heart damage, a new study revealed.

are battery-powered devices that heat a liquid -- including tobacco-derived nicotine, flavouring and other additives -- and produce an aerosol that is inhaled.

According to a study conducted by American Heart Association, flavour additives may impair function and is one of the major early indicators of heart damage.

The widely used flavours in are - menthol (mint), acetylpyridine (burnt flavour), vanillin (vanilla), cinnamaldehyde (cinnamon), eugenol (clove), diacetyl (butter), dimethylpyrazine (strawberry), isoamyl acetate (banana) and eucalyptol (spicy cooling).

According to the study, short-term effects were found on endothelial cells, which line the blood vessels and the inside of the heart.

Researchers found all nine flavours were dangerous to cells in the laboratory at the highest levels tested and all the flavourings impaired nitric oxide production in endothelial cells in culture (outside of the body).

Several of the flavourings - menthol, clove, vanillin, cinnamon and burnt flavouring - resulted in higher levels of an and lower levels of nitric oxide, a molecule that inhibits and clotting, and regulates vessels' ability to widen in response to greater blood flow.

"Increased and a loss of nitric oxide are some of the first changes to occur leading up to and events like and stroke, so they are considered early predictors of heart disease," said

"Our findings suggest that these flavouring additives may have serious consequences."

The study findings appear in Arteriosclerosis, and Vascular Biology Journal.
