People who vape experience 'worrisome changes' in their blood pressure 

Vaping causes your blood pressure and heart rate to spike immediately afterwards, a study claimed.

University of Wisconsin experts found vaping and smoking cause people's heart rates to spike 15 minutes after use and put the body in 'fight or flight' mode. 

The study, presented at the American Heart Association Scientific Sessions 2022, looked at data for 395 participants — 164 vapers, 117 smokers and 114 who had no history of nicotine, e-cigarette or tobacco use.

Co-lead author Matthew Tattersall, an assistant professor of medicine at the university, said: 'Immediately after vaping or smoking, there were worrisome changes in blood pressure, heart rate, heart rate variability and blood vessel tone (constriction).' 

But the study has not been peer-reviewed and was only observational, so researchers could not prove vapes were actually causing the heart issues. 

E-cigarette users are less fit than people who do not vape

Vapers perform worse when exercising than non-smokers and are more akin to smokers, a study claims. 

Researchers looked at data from the same participants as the previous study.

After 90 minutes on the machine, they were given four heart screenings to determine overall health of the organ.

People who vaped scored 11 per cent lower than those who did not use nicotine.

Smokers had test scores 16 per cent lower than the control group. 

Dr Aruni Bhatnagar, a professor of Medicine at the University of Louisville said: 'These studies add to the growing body of science that shows similar cardiovascular injury among people who use e-cigarettes and those who smoke combustible cigarettes.'

Vaping is 'just as bad as cigarettes for your heart'

Vapers are at the same risk of heart disease as cigarette users, according to US federally-funded research. 

In two studies, one on mice and one on people, e-cigarettes were found to cause similar damage to blood vessels as smoking tobacco. 

The findings from experts at the University of California, San Francisco were published in the American Heart Association’s journal Arteriosclerosis, Thrombosis and Vascular Biology (ATVB). 

Despite the difference in ingredients that make up e-cigarette aerosol and cigarette smoke, the researchers found that blood vessel damage does not appear to be caused by a specific component of cigarette smoke or e‑cigarette vapor. 

Rather, it appears to be caused by airway irritation which triggers biological signals in the valgus nerve.

Dr Matthew Springer, a professor of medicine in the division of cardiology at the University of California, San Francisco said: 'We were surprised to find that there was not a single component that you could remove to stop the damaging effect of smoke or vapors on the blood vessels.'  

'As long as there’s an irritant in the airway, blood vessel function may be impaired,' he said.
