A study of 114 found early measures to improve blood vessel health, i. as a "vascular stiffness" within a month of switching from flammable cigarettes to their electronic counterparts.
"The ability of our blood vessels to expand and provide more flow when we need it is associated with long-term results," explained Dr. Rose Marie Robertson, deputy chief scientific and medical officer of the American Heart Association.  But that data is not specific to electronic cigarettes, she warned. "We have no data to prove the long-term safety of vaping," says Robertson, who did not participate in the new study.
In the new study, those who switched to electronic cigarettes more fully and those who smoked less than 20 years saw greater improvements in their vascular function. Like women ̵
The results are independent of whether or not a nicotine-containing cigarette is present. The authors hypothesize that "early improvement does not appear to be related to nicotine abstinence, but rather to other toxic materials produced by burning" in conventional cigarettes.
Robertson says the study was well done, but his findings have important observations. For example, there were a number of factors that remained unchanged for smokers who passed, including markers of inflammation and platelet reactivity.
In addition, the study was conducted at an institution, the University of Dundee in the United Kingdom, "where the levels of nicotine provided by Electronic Cigarettes are significantly lower" , she said, making it "impossible to translate this to products available in the United States. "
"The find from [new study’s] contradicts the findings of observational studies that found that viral people are at a higher risk of heart disease because these studies are inevitably and irreversibly confused by former smoking," he says Jon Britton, director of the Center for Research on tobacco and alcohol in the UK, in a statement by email. Britton did not participate in the new survey.
Robertson of the American Heart Association stated that "the big message … is that giving up burning cigarettes is probably the most important thing you can do for your health."
When it comes to vaping, "saying it's safer than cigarettes is not the same as saying it's safe," Add Robertson.
