Cigarettes Linked to Heart Attacks, Strokes

"But this study and previous other studies show that while they're less harmful than normal cigarettes, their use still comes with risks".

E-cigarettes, which are battery-operated devices used to inhale an aerosol, usually containing nicotine, were first introduced to the market in 2004.

Researchers at the American Heart Association analysed health data from 400,000 people who responded to the 2016 behavioural risk fact surveillance system survey.

Study author Assistant Professor Paul Ndunda of the School of Medicine at the University of Kansas, said: 'Compared with non-users, e-cigarette users were younger, had a lower body mass index and a lower rate of diabetes'.

Using e-cigarettes, or vaping, doesn't burn tobacco, and doesn't produce a tar or carbon monoxide, said the NHS.

The researchers looked at data for 66,795 e-cigarette users and 343,856 non-smokers, and found that using e-cigarettes could increase a person's risk for a variety of conditions.

New preliminary research to be presented at the American Stroke Association's International Stroke Conference in Honolulu in February suggests that people who smoke e-cigarettes are more likely to suffer from heart disease and stroke than non-smokers. They also confirmed in the largest study on the e-cigarettes and stroke, that there is a link between vaping and potentially fatal blood clots.

To see the health effects 0f e-cigarette use alone, Ndunda and his colleague Dr. Tabitha Muutu compared people who had only used e-cigarettes - not conventional cigarettes - to nonsmokers.

In its survey of 400,000 people, the AHA found that almost 66,795 respondents who vaped had a 71 percent higher risk of stroke.

One in 20 adults in the USA is reported to vape, and according to the research carried out by the American Heart Association, vaping could increase their chances of suffering a heart attack by nearly 60 percent.


However, because this is survey data, it can not draw a direct cause-and-effect relationship between vaping and stroke or heart attack, Ndunda added.

The same people were 59 percent more likely to have angina or a heart attack and 40 percent more likely to develop heart disease.

But, the NHS said e-cigarettes carry a small fraction of the risk of cigarettes.

E-cigarette smoking may contribute to the gradual buildup of fatty deposits in arteries, Glantz says.

The American Heart Association claimed that e-cigarettes containing nicotine should be subjected to the same laws as tobacco products.

And they also found that vaping doubles your chance of starting to smoke cigarettes. However, Goldstein noted that the study had limitations. "It likely matters how much you're using, and we couldn't evaluate that here", Ndunda told NPR.

"There is variability in e-cigarettes and the dose they deliver of nicotine", he said, adding that "nicotine isn't the only thing in these e-cigarettes and different companies manufacture them", so their ingredients lists can vary widely.

Ndunda added that a study that identifies e-cigarette users early and then tracks their health over time would yield a clearer picture of the consequences of vaping.

He also called for a ban on sweet flavoured e-liquids that are so enticing to younger users.
