E-cigarettes are equally as harmful for your heart as regular cigarettes, according to TWO MORE NIH studies.
According to study, vaping produces “worrisome alterations” to a person’s blood pressure, heart rate, and degree of fitness.
These changes appear to occur much more quickly in e-cigarette users than in regular tobacco smokers, according to two recent federally funded research, which is concerning.
Before, vaping was promoted as a healthier substitute for cigarettes, which significantly increase the risk of heart disease, lung cancer, and other chronic illnesses.
But a tonne of evidence in recent years indicates that the electronic substitutes harm the body in a similar way.
Researchers found that smoking and vaping cause people’s heart rates to increase 15 minutes after consumption and put the body in “fight or flight” mode.
Additionally, the brachial artery, which is the main blood vessel delivering blood to the arms and hands, was narrowed in both groups.
Atherosclerosis and high blood pressure can prevent the heart from receiving oxygen-rich blood, which over time raises the risk of developing heart disease.
In a second trial, participants ran on a treadmill for 90 minutes before undergoing a battery of cardiovascular examinations.
All indicators, including how quickly heart rate recovered after exercise and how hard the heart had to work at peak levels, were significantly poorer in those who smoked or vaped.
Dr. Christina Hughey, the study’s lead author from the University of Wisconsin, claimed that even while vapers had been using vaporizers for less years than smokers and were younger, their exercise performance was not significantly different from that of smokers.
Matthew Tattersall, co-lead author and assistant professor of medicine at the institution, added: “There were alarming changes in blood pressure, heart rate, heart rate variability, and blood vessel tone (constriction) immediately after vaping or smoking.”
Presented at the American Heart Association Scientific Sessions 2022 were the findings of both investigations.
It happens in the midst of a vaping epidemic in the US, where 2.5 million children and 8 million adults use the devices. More than 3 million Britons use it frequently.
Although e-cigarettes are frequently touted as healthier alternatives to traditional cigarettes, they still contain a number of dangerous substances.
E-liquids have nitrosamines, which have been associated with cancer, and flavoured vapes frequently comprise diacetyl, an irritant associated with the fatal illness known as “popcorn lung.”
Science is also starting to indicate that the devices can harm heart health just as much as smoking does.
Researchers analysed data from 395 participants in the most recent trial, including 164 vapers, 117 smokers, and 114 individuals without a history of nicotine, e-cigarette, or tobacco use.
Before and 15 minutes after vaping and smoking, researchers measured blood pressure, heart rate, the brachial artery’s diameter in the arm, and heart rate variability.
Data indicate that, compared to non-users, persons who vaped or smoked cigarettes experienced a four beats per minute quicker pulse after doing so.
The study also discovered that while utilising devices with a mercury content ranging from 122/72 millimetres (mm HG) to 127/77 mm Hg, smokers and vapers saw an increase in blood pressure.
A second study discovered that vapers’ exercise performance was comparable to that of smokers and was poorer than that of non-smokers.
In a preliminary investigation, it was discovered that smokers and vapers had an average heartbeat that was 4 beats per minute faster than that of non-smokers.
“These findings suggest worse cardiovascular disease risk factors immediately after vaping or smoking, and activation of the sympathetic nervous system may play a role in the adverse responses seen immediately after using e-cigarettes and after exercise testing 90 minutes later,” Dr. Tattersall continued.
The same participants underwent a treadmill stress test in a subsequent investigation.
They had four cardiac examinations to assess the overall condition of the organ after 90 minutes on the machine.
The scores of vapers were 11% lower than those of non-users of nicotine.
Test results for smokers were 16% poorer than for the control group.
Additionally, they reported a bigger difference between their resting and exercise heart rates, indicating that their hearts were working harder during exercise.
In comparison to smokers, vapers’ reserve heart rate was 30% greater and their exercise heart rate was 40% higher.
Both smokers and vapers had lower cardiac workloads than their friends who did not use nicotine, and it took them longer to recover from exercise before their heart rates returned to normal.
Even if these results are concerning, researchers caution that there is still a lot of evidence supporting the negative effects of vaping.
“These findings contribute to the expanding body of data that reveals identical cardiovascular harm among persons who use e-cigarettes and those who smoke combustible cigarettes,” said Dr. Aruni Bhatnagar, a professor of medicine at the University of Louisville.
Additionally, it demonstrates that this cardiovascular risk exists even in younger individuals with less recent nicotine use.
“People should be aware that combustible cigarettes and e-cigarettes both contain toxic chemicals and addictive nicotine that may be harmful to their cardiovascular system and general health.”
Dr. Bhatnagar participated in a study that was just released last week and discovered that mice’s heart rates were significantly lowered after exposure to e-cigarette smoke.
Last week, a different study supported by the National Institutes of Health discovered that mice’s blood arteries narrowed when exposed to e-cigarette smoke.
