Vaping better than cigarettes for blood vessel health – study

Blood vessel function found to improve within a month if e-cigarettes replaced with e-cigarettes

Switching from tobacco cigarettes to vaping improves blood vessel function within one month, researchers have found, in a study they say supports the use of electronic cigarettes as a tool to quit smoking.

E-cigarettes have becoming a booming business, with the number of people who vape growing rapidly. According to a 2017 report by Ernst and Young, 2.2 million Britons use e-cigarettes, an increase of 55% over three years.
However, there has been much debate over the potential benefits or harm caused by the devices.

DOES THE END REALLY JUSTIFY THE MEANS IN ALL CASES

The new study suggests switching from tobacco cigarettes to vaping could be a positive move for blood vessels, potentially reducing the risk of heart attacks and strokes.
“Switching from tobacco cigarettes to electronic cigarettes improves your vascular function within the period of a month, significantly,” said Prof Jacob George of the University of Dundee, first author of the study.

The study pushes back against research published earlier this week that suggested e-cigarette use might impair blood vessel function. George and colleagues say that study was very small and flawed – not least because it looked only at the impact of a single vaping session.

Writing in the Journal of the American College of Cardiology, George and colleagues report that they looked at data from 114 adults, split into three groups, all of whom smoked at least 15 cigarettes a day for at least two years but had no signs of cardiovascular disease.

One group contained 40 people who did not wish to quit traditional smoking, while the other two groups each contained 37 similar people who did, with one group given devices containing nicotine and the other given e-cigarettes without nicotine.
The team measured blood vessel function at the outset of the study, and after one month, by comparing artery diameter before a tight cuff was applied to an arm with artery diameter just after the cuff was released. This percentage change is larger in healthier vessels.

They found those who continued to smoke tobacco cigarettes showed little difference in their blood vessel function over the month.. However, those in the vaping groups had more than a 20% relative improvement in the measure and were halfway back to having blood vessel function on a par with non-smokers. Similar results were found for those switching to e-cigarettes with and without nicotine.
