The nicotine in electronic cigarettes can cause heart disease

Previously it was thought that the only risk adding nicotine in the liquid for steam generators - is the emergence of dependence. But there are more serious and harmful.
according to a studySympathomimetic Effects of Acute E-Cigarette Use: Role of Nicotine and Non-Nicotine ConstituentsPublished in the Journal of the American Heart Association, nicotine is not harmless, as many believe. It can not only be addictive, but also increase the risk of heart disease.
"There is an old saying according to which people smoke because of nicotine, because it is highly addictive, but die from resin ", - said Holly Midlkauff (Holly Middlekauff), one of the authors of the study and a cardiologist at the University of California Los Angeles. This belief has led to the appearance in the 70-ies of XX century nikotinozameniteley like special patches and gum to help people quit smoking. Today, for many this means the replacement steam generators electronic act.
Scientists still arguing about the safety of electronic cigarettes. Last year, the British Royal College of Physicians recommend tobacco smokers to switch on the steam generators to throw. At the same time centers for Disease Control and Prevention in the US said: there is no evidence that electronic cigarettes work as a smoking cessation tool.
But there are more studies that prove harm to the steam generators.
In 2015, it became knownExposure to Electronic Cigarettes Impairs Pulmonary Anti-Bacterial and Anti-Viral Defenses in a Mouse ModelThat vaporizer harm the immune system of mice. And last year, it became clearAll E-Cigarettes Emit Harmful Chemicals, but Some Emit More Than OthersThat e-cigarettes produce the harmful chemical 31, with some of these substances can cause cancer.
Another studyIncreased Cardiac Sympathetic Activity and Oxidative Stress in Habitual Electronic Cigarette UsersSpent Midlkauff and published earlier this year showed that people using electronic cigarettes almost every day, there are biomarkers that increase the risk of heart disease in tabakokurilschikov. Among these biomarkers - increase the level of adrenaline in the heart, which predisposes to poor heart rate and heart attacksAs well as the occurrence of oxidative stress, which can lead to arteriosclerosis.
This study, however, did not reveal what exactly causes these changes. The fluids of steam generators, in addition to nicotine, can contain various flavorings and solvents. To find the cause of the aforementioned biomarkers Midlkauff invited 33 healthy people who do not smoke and do not hover. Once a month they came to the laboratory, where for 30 minutes were the use of electronic cigarettes. Once liquid has been nicotine once - no, and once obtained the test pacifier without any substance.
The researchers did blood tests and measured the heart rate of participants.
It was found that the subjects increased level of adrenaline in the heart only after the use of electronic cigarettes with nicotine.
The question of oxidative stress remains open, because the experiment was designed to identify only one marker.
This is a fairly small study, so he can not be trusted to 100%. It also found that the guy is directly related to heart disease. One can only conclude that if a person smokes a cigarette ordinary, the transition to electronic to help him, since they contain far fewer carcinogens. But if you do not smoke, Midlkauff strongly recommends do not take into the hands of steam.
