What effect do e-cigarettes have on the blood?
The impact of traditional cigarette smoking on the heart and lungs is well known, as it often leads to thrombosis, heart attacks and strokes.
Now, new research reveals that nicotine-containing e-cigarettes cause similar problems with blood clots as regular cigarettes.
Dr. Gustaf Lyytinen, of Helsingborg Hospital and a researcher at the Karolinska Institute in Sweden, says that steam products, which use the same addictive chemical (nicotine) found in regular cigarettes, lead to blood clots and blood clots. and expand properly. In addition, a study of occasional smokers who took just 30 e-cigarette puffs showed that the user's heart rate and blood pressure also increased after vaporization.
The research team says that, in the short term, these results are similar to the impact of smoking regular cigarettes with nicotine. After long-term use, the researchers added that smokers of both products (regular cigarettes and e-cigarettes) are at risk for heart attacks and strokes.
What effect do e-cigarettes have on the blood?
The study authors looked at 22 healthy men and women between the ages of 18 and 45 who reported occasionally smoking. Each person took 30 puffs from an e-cigarette containing nicotine and then took 30 puffs from a nicotine-free e-cigarette a week later.
The team of Dr. Lyytinen collected blood samples before and after each e-cigarette experiment. They also put the team to special tests designed to measure blood flow and blood circulation through tiny blood vessels.
On average, the study authors found:
- 23% increase in blood clots just 15 minutes after using an e-cigarette full of nicotine. These levels returned to normal after about an hour
- increases in each volunteer's heart rate, from 66 beats / minute to 73 beats / minute
- blood pressure also increased, going from 108 mmHg to 117 mmHg on average
Is there a safe alternative to smoking cessation?
The study did not show the same results after participants took 30 puffs of e-cigarettes without nicotine. Previous studies have found a link between nicotine intake and increased hormones, such as adrenaline, which can also lead to blood clots.
“Our results suggest that the use of nicotine-containing e-cigarettes has similar effects on the body as traditional cigarette smoking. “This effect on blood clots is important because we know that in the long run it can lead to clogged and narrower blood vessels and this of course puts users at risk for heart attacks and strokes,” said Dr. Lyytinen.
“The damage caused by smoking traditional cigarettes, including the effects of nicotine on the body, is well known. “Electronic cigarettes are relatively new, so we know much less about what they do to the body,” said Jonathan Grigg, chairman of the European Respiratory Society's Tobacco Control Committee, who did not take part in the study.
“Some people may choose e-cigarettes when trying to quit smoking because e-cigarettes are marketed as safe. But this study adds to the growing evidence for the harmful effects of e-cigarettes. “Other evidence-based smoking cessation aids recommended by the European Respiratory Society (ERS), such as patches or nicotine gum, do not expose the lungs to high concentrations of potentially toxic compounds.” .
