E-cigarettes can increase the risk of heart attacks and strokes, find assessments while experts urge the government to stop recommending fumes to smokers

Vapen can increase the risk of a heart attack or stroke, scientists have warned.

Researchers viewed 38 studies and revealed that e-cigarettes caused cardiovascular damage in nearly three-quarters of the tests.

Human studies showed that sheep led to increased heart rate and blood pressure, as well as stiffness of the arteries and abnormal coagulation.

And it also increased the risk of plaque in the vessel walls, which could lead to a heart attack, experts said.

Mice exposed to e-cigarette vapor also developed an accumulation of plaque in their arteries and suffered damage to blood vessel lining.

The analysis, conducted by researchers in London and Denmark, has led to calls for Public Health England (PHE) to stop recommending vapen.

Since 2015, PHE has advised tobacco smokers to switch to e-cigarettes and claims that it is 95 percent safer. There are now around four million Britons who regularly vape.

However, the authors of the new assessment discovered that the government used an e-cigarette industry-funded study to advise that vapen was safe.

Scientists also discovered that most studies funded by the tobacco industry had no harmful effects on the heart.

But when the research team discounted those tests, the number of investigations with cardiovascular damage increased to 90 percent.

HOW CAN VAPEN BE HARMFUL?

The flavors in electronic cigarettes can damage blood vessels in the same way as heart disease, according to research published in June.

The chemicals used to give the vapor flavors, such as cinnamon, strawberry and banana, can cause inflammation in cells in the arteries, veins and the heart.

They ensure that the body responds in a way that mimics the early signs of heart disease, heart attack, or stroke, the Boston University study found.

Other recent studies have also suggested that smoking e-cigarettes can cause DNA mutations that can lead to cancer and cause bacteria that cause pneumonia to stick to the lungs more easily.

Researchers at New York University have exposed human bladder and lung cells to e-cigarette vapor, which is marketed as healthier than tobacco.

They found the cells mutated and became cancer much faster than expected and mice exposed to the vapor also suffered significant DNA damage.

In another study, scientists at Queen Mary University in London discovered that vape users are more likely to cause pneumonia – just like smoking tobacco or breathing in traffic fumes.

The vapor from e-cigarettes helps bacteria that cause the condition to stick to the cells along the airways, they said.

The effect occurs with traditional cigarette smoke and people exposed to air pollution with many particles from vehicle exhaust gases.

Last week, US health officials warned people to stop vaping after the death of four people and the widespread disease of e-cigarette smokers.

Martin McKee, professor of European public health at the London School of Hygiene and Tropical Medicine, who co-authored the new study The Telegraph: & # 39; What is amazing is how PHE ignores the worries, almost as if people in the UK have lungs that work differently than those in the US.

& # 39; Since the appearance of the number & # 39; We are 95 percent safer & # 39; concerned about conflicts of interest.

& # 39; We would not be naive if we were dealing with a multi-billion dollar company that is largely led by the tobacco industry. What is surprising is that some people do not see this as a problem. & # 39;

Asked if PHE should change its advice, Professor McKee said: & # 39; The simple answer is yes. & # 39;

In March, the University of Kansas looked at 90,000 e-cigarette smokers and discovered that they were 34 percent more likely to develop a heart attack or develop coronary heart disease compared to non-smokers.

In May, researchers from Stanford University suggested that sheep could increase the risk of heart attack or stroke because of the aromas in e-cigarettes.

Scientists who tested the flavored "e-liquids" in the devices discovered that they damage the cells that line the blood vessels, which can lead to cardiovascular disease.

Electronic cigarettes are much less dangerous to health than conventional cigarettes because they do not contain tobacco that causes lung cancer.

However, they contain nicotine, which can narrow and harden the arteries, and often taste to make the vapor they produce more attractive.

The research team tested six flavors, including fruit, tobacco flavors, cinnamon and menthol, on the cells along the blood vessels.

They discovered that the flavors, including different levels of nicotine, caused DNA damage, cell death, and inflammation.

The new study is published in the journal Preventive medicine.

What is an e-cigarette and how does it differ from smoking tobacco?

An electronic cigarette (e-cigarette) is a device that allows users to inhale nicotine by heating a vapor from a solution containing nicotine, propylene and flavorings.

Because there is no burning, there is no smoke like a traditional cigarette.

But although they are branded as a lower risk than cigarettes, an increasing stream of investigations shows health hazards.

E-cigarettes do not produce tar or carbon monoxide, but the vapor does contain some harmful chemicals.

Nicotine is the highly addictive chemical that makes it difficult for smokers to quit.

Nearly three million people in the UK use e-cigarettes and more than nine million Americans.

TYPES:

1. Standard e-cigarette

Battery-powered device containing nicotine e-liquid.

It evaporates flavored nicotine liquid.

2. Juul

Very similar to normal e-cigarettes, but with a slimmer design and a higher concentration of nicotine.

Advertisements

Thanks to the & # 39; nicotine salts & # 39; manufacturers claim that one pod delivers the amount of nicotine as a pack of cigarettes.

It consists of an e-cigarette (battery and temperature control) and a pod e-liquid that is introduced at the end.

The liquid contains nicotine, chemicals and flavorings.

Like other evaporation devices, it evaporates the e-liquid.

3. IQOS by Philip Morris

Pen-shaped, charged like an iPod.

Evaporated tobacco.

It is known as a & # 39; heat not burn & # 39; smokeless device that heats but does not burn tobacco (at 350 ° C compared to 600 ° C as normal cigarettes do).

The company claims that this method reduces the exposure of users to carcinogenic burning tobacco.
