Electronic cigarettes contribute to the increased risk of atherosclerosis

The use of electronic cigarettes can even help cut the addiction , but does not reduce the risk of atherosclerosis , the major cause of heart attacks worldwide . Study in tissues of rats and humans showed that exposure to nicotine - the addictive substance main cigarette and is also present in electronic cigarettes - can cause damage to heart cells .
" The results suggest that electronic cigarettes do not reduce the risk of smoking to heart disease," said Chi - Ming Hai , a researcher at Brown University in the United States , and author of the study recently presented at the annual meeting of the American Society for Cell Biology .

The increased risk of developing atherosclerosis in smokers of ordinary cigarettes because of other chemicals have been proven some years ago , but still do not know what mechanism caused the nicotine was related to the invasion of vascular smooth muscle cells - cells found on the inside of the blood vessels. Now , tests at the vascular smooth muscle cells of rats and humans have shown that there is a direct relationship between nicotine and atherosclerosis .
Typically , vascular muscle cells are around the blood vessels to help maintain blood flow and blood pressure under control. The nicotine and other chemicals cigarette , however , makes these cells act as " bits " in the bore of the protection of the heart vascular cell layer , thereby forming the process of atherosclerosis , plaque blocking the blood flow.electronic cigarette wholesale supplier
In the study, appeared as nicotine conductive increase invasion of vascular smooth muscle cells from the medial layer of the arterial wall to the inner layer of the arterial wall , which increases the plaque formation in atherosclerosis .

The study of Chi - Ming Hai contradicts what is said about electronic cigarettes , promoted as safe nicotine delivery systems for health . In the electronic cigarette , different from ordinary cigarettes , nicotine is provided in the form of steam and without agents , known as carcinogens , in tobacco smoke .
The scientist says that on the one hand , the use of nicotine in the treatment helps to mill the common cigarette, on the other , the long-term consumption of nicotine through the electronic cigarette increases the risk of developing atherosclerosis . " Still , I believe the understanding of the mechanisms between nicotine and atherosclerosis may lead to new therapies to minimize the harmful effects of nicotine on the vascular system , "he said .
