The e-cigarette is less dangerous than tobacco? This no longer seems to be in doubt despite many surprising studies. Yet recent work published in the scientific journal Journal of the American College of Cardiology demonstrate that vaping leads to significant improvements in cardiovascular health in smokers.
A BENEFIT OF MORE IMPORTANT VAPOTAGE IN WOMEN!
Through the study VESUVIUS commissioned by the British Heart FoundationScottish researchers have recently demonstrated that the use of e-cigarettes leads to significant improvements in cardiovascular health among smokers. The work was published in the scientific journal Journal of the American College of Cardiology.
« There have been many fears about the cardiovascular effects of vaping. These were generally based on the delivery of e-liquid to cells in petri dishes, poisoning of mice with massive doses of chemicals unrelated to human spraying, or misinterpretation of the acute stimulatory effects of spraying, of which the health effects are similar to the ingestion of coffee", Annoys the Pr Peter Hajek, Director of the Tobacco Dependence Research Unit, Queen Mary University, London, on the Science Media Center.
Like many specialists, he was waiting for relevant data on humans: the study VESUVIUS commissioned by the British Heart Foundation would have been the largest company to date to determine the impact of e-cigarettes on heart health, with results published by the Journal of theAmerican College of Cardiology.
A two-year trial conducted by the university's Faculty of Medicine found that smokers who switched to e-cigarettes showed a significant improvement in their vascular health in four weeks, with women making larger gains than men. The study also found that participants in transition had greater improvement than those who continued to use both tobacco and electronic cigarettes.
Professor Jacob George, a professor of cardiovascular medicine in Dundee and chief investigator of the trial, said that although e-cigarettes have been shown to be less harmful, the devices in question could still pose health risks.
« It is crucial to stress that e-cigarettes are not safe, but remain less harmful to vascular health than tobacco. Smoking is an avoidable risk factor for heart disease. »He declares before adding« They should not be considered harmless devices for non-smokers or young people. However, in chronic tobacco smokers, vascular function improved significantly less than a month after switching from smoking to vaping.".
« To put it in context, each percentage point of improvement in vascular function results in a reduction of 13% in the rate of cardiovascular events such as heart attacks. By switching from tobacco to e-cigarette, we have seen an average improvement of 1,5 point in just one month. This represents a significant improvement in vascular health. We also found that in the short term at least, whether the e-cigarette contains nicotine or not, a person would notice an improvement in their vascular health with vaping. The long-term impact of nicotine use requires further study and monitoring. »
« Women have benefited a lot more than men by choosing the e-cigarette, and we are always looking for the reasons. Our research also revealed that, if a person had smoked less than 20 years, the rigidity of his blood vessels also improved considerably compared to those who smoked more than 20 years ".
AN ENHANCEMENT OF THE HEALTH OF THE ARTERIES IN ONLY ONE MONTH WITH THE VAPE!
The study VESUVIUS recruited 114 long-term smokers who had smoked at least 15 cigarettes daily for at least two years. Participants were divided into one of three groups for one month: those who continued to smoke tobacco, those who switched to the e-cigarette with nicotine and those who switched to the e-cigarette without nicotine. Participants were monitored throughout the test period while undergoing vascular tests before and after the test.
Professor Jeremy Pearson, Associate Medical Director at the British Heart Foundation, said, " Our heart and our blood vessels are the hidden victims of smoking. Every year in the UK, 20 000 people die from heart and circulatory disease caused by smoking. 50 people per day, or two deaths per hour. Stopping smoking is the best thing to do for your heart health. »
According to him " this study suggests that vaping may be less harmful to blood vessels than smoking. After just one month of quitting smoking for the e-cigarette, the health of people's blood vessels had begun to recover. »
He recalled, however, that "it is not because e-cigarettes are less harmful than tobacco that they are completely safe. We know that they contain far fewer harmful chemicals that can cause smoking-related diseases, but we still do not know the long-term effects. Vaping should never be used by people who do not smoke yet, but could be a useful tool to help quit smoking. "
For his part, the Scottish Minister of Public Health, Joe FitzPatrick MSPsaid: "I welcome the publication of this report, which contributes to the ongoing debate on the place of e-cigarettes in our communities. It is good to see important and relevant studies like this one produced in Scotland and justifying our reputation of being one of the leading centers for medical research.
« Although research shows that switching to e-cigarettes may have beneficial effects on the vascular health of chronic tobacco smokers, access to it must be carefully controlled as these are simply not products for children or non-smokers. »
