Vaping less harmful than smoking for vascular health
According to news from CNN, an important research result from the University of Dundee in the UK shows that the switch from traditional cigarettes to e-cigarettes is significantly beneficial to the heart health of smokers: compared to traditional cigarettes, e-cigarettes have less harm to vascular health and reduce Cardiovascular disease risk.
This major study was named VESUVIUS and was commissioned by the British Heart Foundation. It is also considered to be the largest study to date on the effect of e-cigarettes on the heart, and its findings are published in the Journal of the American College of Cardiology.
The study, conducted by the University of Dundee Medical School in the United Kingdom over a two-year period, recruited 114 smokers who have smoked traditional cigarettes for a long time. These subjects smoked more than 15 cigarettes a day for at least two years. They were divided into three groups: the group that continued to smoke traditional cigarettes, the group that switched to nicotine-containing electronic cigarettes, and the group that switched to 0-nicotine electronic cigarettes. The experiment period is one month, and the health status of these subjects will be monitored throughout the experiment. Before and after the experiment, researchers will also test their blood vessel health.
When traditional cigarette smokers switched to e-cigarettes, their blood vessel health improved significantly in just four weeks, and it was more pronounced for female smokers. The study also found that among subjects, those who switched completely to e-cigarettes had greater improvements in vascular health than those who smoked both conventional cigarettes and e-cigarettes.
University of Dundee research shows that when smokers of traditional cigarettes switched to nicotine-containing electronic cigarettes, their blood vessel health improved significantly.
George Jacob George, Professor of Cardiovascular Medicine and Therapy at the University of Dundee, served as the lead investigator for the study. He said that although e-cigarettes are not completely harmless, they are far less harmful than traditional cigarettes in terms of vascular health. Non-smokers or minors should not try e-cigarettes. However, for those who have been smoking traditional cigarettes for a long time, the blood vessel function has been significantly improved only one month after they switched to e-cigarettes.
“Medical research shows that for every 1 percentage point increase in vascular function, the incidence of cardiovascular disease (such as a heart attack) decreases by 13%. We found that when smokers switched from traditional cigarettes to e-cigarettes, within a month they The average vascular function improved by 1.5 percentage points. This data means that their vascular health has improved significantly. And, by switching to e-cigarettes, women benefit more than men, and we are still studying the reasons for this phenomenon, “said George.
At the same time, the Scottish Public Health Minister Joe FitzPatrick MSP said, “I am very supportive of the publication of this report, which will promote continuous discussion of e-cigarettes in all sectors of society. I am also glad to see that there is such an important research in Scotland This also confirms our reputation as a cutting-edge position in medical research. Although research shows that long-term smokers’ switch to e-cigarettes is beneficial to their vascular health, we still need to use e-cigarettes with caution, it is not for minors or Products offered by smokers. “
