E-cigarette use linked to heart trouble

But e-cigarettes may help pull some people away from smoking tobacco cigarettes and they could also act as a gateway product others who never smoked anything at all.

"Until today, the effects of electronic cigarette use on the heart and veins were not known much".

The rate of heart attacks among those who vape was 34% higher than among those who don't, once corrections were made for risk factors such as age, gender, body mass index, cholesterol level, blood pressure and tobacco use.

A new study has found an association between vaping, or the increasingly popular use of e-cigarettes, and negative cardiovascular health outcomes, including increased odds of having a heart attack, developing coronary artery disease or experiencing depression.

"We found that regardless of how frequently someone uses e-cigarettes, daily or just on some days, they are still more likely to have a heart attack or coronary artery disease", he said.

But taking into account the fact that people who were also regularly smoking tobacco had a 165 per cent increased heart attack risk, they calculated the increased isk of vaping alone dropped to about 34 per cent.


The study, based on data of 96,467 people from the National Health Interview Survey, is considered one of the largest focusing particularly on e-cigarette usage and cardiovascular risks.

"Until now, little has been known about cardiovascular events relative to e-cigarette use", Dr Mohinder Vindhyal, assistant professor at the University of Kansas School of Medicine Wichita and the study's lead author said.

It's all down to the flavourings in e-cigarettes, which scientists found can harm the lungs further by triggering lung inflammation. But e-cigarettes are also hotly debated-touted by some as a safer alternative to smoking tobacco, while others are concerned about their implications on public health. Those who reported using e-cigarettes were younger than nonusers (33 years of age on average vs. 40.4 years old).

The team's initial analysis suggested e-cigarette users had a 56 per cent increased risk of heart attack than those who did not vape. The study conducted by a team from the University of Kansas in the US showed that e-cigarette users were twice as likely to suffer from depression, anxiety and other emotional problems. "Stroke, high blood pressure and circulatory problems were no longer statistically different between the two groups".

"What we're trying to see is if they are as safe as the public health organizations are saying, or is it even associated with other cardiovascular outcomes", he said, while noting that the study could only find association.

"It is an important finding that electronic cigarette users have elevated health risks", commented Michael Ong, MD, of the University of California Los Angeles. Follow @ACCinTouch, @ACCMediaCenter and #ACC19 for the latest news from the meeting.
