According to a recently published study, the chemicals in the electronic cigarette vapor could potentially produce short-term cardiovascular damage.
According to this study, which compared the effects of smoking and vape on voluntary subjects by using the same nicotine content on the blood vessels, the signs of damage appear similar or a little less important for the vape than those induced by smoking. . However, the study found no evidence of actual harm.
The researchers looked at a number of markers, including those of oxidative stress, vitamin E levels, and the bioavailability of nitric oxide. They also performed flow-mediated dilation, or FMD, which determines the ability of blood vessels to dilate to carry more blood.
«Our study demonstrates that both cigarettes (and e-cigarettes) have adverse effects on oxidative stress and FMD markers after single use, although e-cigarettes appear to have less impact,". " Future studies will be needed to clarify the chronic vascular effects of vaping »
The study was carried out in 40 healthy men and women, 20 smokers and 20 non-smokers. This was published in the journal Chest by a team led by Roberto Carnevale from the Sapienza University in Rome, Italy. (See the study)
