A recent American study shows for the first time that vaping on a daily basis doubles the probability of having a heart attack, in particular because of the nicotine and the products contained in the liquids.
While a recent study has shown that vaping changes DNA and could cause cancer, researchers at the University of California San Francisco and George Washington University found that this daily practice would also double the risk of heart attack compared to non-smokers.
69,452 people were asked about their consumption of tobacco, electronic cigarettes and the history of their heart health. Of 9,352 occasional electronic cigarette consumers, 333 (3.6%) had a heart attack (infarction). For those who vape daily, that figure rises to 6.1%.
The danger of smoking tobacco and vaping
For consumers who combined electronic cigarettes and tobacco, the likelihood of having a heart attack was 4.6 times that of people who had never used both products at the same time. “Most adults who vape continue to smoke cigarettes,” analyzes Stanton Glantz, study director, published in theAmerican Journal of Preventive Medicine.
“While they think they are reducing their health risks, we have found that the risk of heart attack from e-cigarettes adds to the risks from cigarettes. Someone who continues to smoke every day using e-cigarettes increases the likelihood of a heart attack by five times. “
The chances of a myocardial infarction also increase with a history of hypertension, high cholesterol, diabetes and age, which means that the risk is cumulative. “Women were less likely to have a myocardial infarction,” the scientists also note.
“The risk drops immediately after stopping smoking”
The only good news for smokers is that it’s never too late to quit. “The risk of heart attack drops immediately after stopping smoking,” says Stanton Glantz. “Our results suggest the same is true when they stop vaping.” The data for this study were collected in 2014 and 2016 and analyzed in 2017 and 2018.
All electronic cigarettes are based on the same principle. The user presses a button and a trigger. At this time, a small amount of liquid is drawn into a chamber. Then a heating battery atomizes this liquid, which releases vapor. The latter is then sucked into the lungs of the vapoteur.
This process does not have the same toxic effects as smoking, such as the combustion effect for example, and the vapor contains less carcinogens. But some liquids contain nicotine of course, solvents, preservatives or even flavors and other toxicants which, contained in ultrafine particles, can be dangerous.
