Electronic cigarettes reduce blood flow in the heart (study)

UNITED STATES (OBSERVATORY NEWS) — Smoking electronic cigarettes significantly affects heart health by lowering blood flow levels, according to a new US study.

The study, conducted by researchers at the Tobacco Center of the American Heart Association, will present its findings to the annual conference of the association, which will be held from 16-18 November in Pennsylvania, USA.

The American Heart Association recommends that people stop smoking using nicotine substitutes, approved by the US Food and Drug Administration, which have proven safe and effective.

If they choose to use e-cigarettes during their trip to stop smoking other tobacco products, people should also plan to stop e-cigarettes, given the lack of information about their long-term safety and the growing number of data monitoring their physiological effects on body health, they said.

The effect of e-cigarettes on body fat levels, the researchers followed 476 healthy people between the ages of 21 and 45 who did not suffer from cardiovascular disease, including 94 who did not smoke e-cigarettes, and the rest smoked e-cigarettes only or conventional cigarettes only. , Or smoking both.

The researchers compared cholesterol, triglycerides and glucose levels in the study, factors that negatively affect heart health.

Researchers found that levels of bad cholesterol, triglycerides and glucose were higher among those who smoked e-cigarettes only, those who smoked traditional cigarettes only, or those who smoked both electronic and conventional cigarettes, compared to those who did not.

In a separate study, the researchers analyzed the heart’s blood flow, a measure of coronary vascular function, for 19 smokers between the ages of 24 and 32 years immediately before and after smoking electronic or conventional cigarettes.

The researchers found that smoking electronic cigarettes is associated with dysfunction of coronary blood vessels, and affects the flow of blood in the heart, similar to the smoking of traditional cigarettes.

“Although primary care providers and patients may think that using e-cigarettes if used in place of conventional cigarettes does not affect heart health, our study proves the opposite,” said Dr. Sana Majid, co-researcher.

She added: “We were surprised by the low blood flow in the heart at rest, even in the absence of tension, after inhaling the smoke of electronic cigarette, and this poses a risk to the health of the heart, especially for people at risk of cardiovascular disease.”

Electronic cigarettes work through a heat heater to heat a liquid containing nicotine inside, turning the liquid into the nicotine vapor that inhaled by smokers instead of heartburn, as in the usual cigarettes.

Previous studies revealed that the flavors used in e-cigarettes cause inflammatory and oxidative responses in lung cells, and the effects of those flavors extend to the blood, they are toxic and cause the death of white blood cells.

The World Health Organization also published a report in 2015 warning that e-cigarettes contain toxic substances harmful to health. The Soul

According to WHO, tobacco kills nearly 6 million people in the Eastern Mediterranean Region each year, including more than 5 million former and current tobacco users, and about 600,000 non-smokers exposed to secondhand smoke.
