According to a recent study, e-cigarettes may impair heart muscle function.
Deemed a more healthful alternative to smoking, Vaping might not be completely harmless after all. This is the key message from a new study, which found that some flavourings added to e-cigarette liquids could be damaging for the heart.
According to the research, a number of chemicals used to flavour the liquid - including cinnamon and citrus - could in fact impair the function of heart muscle cells.
The alarming news was discovered by researchers at the University of Louisville in Kentucky, and the findings were recently published in the journal Circulation.
E-cigarettes have been available in America (where the study was conducted) for almost a decade, and their popularity immediately soared among youths. According to a 2016 report from the Surgeon General, e-cigarette use among high school students in the United States increased by a whopping 900 percent between 2011 and 2015.
In many instances, the battery-operated devices are often marketed as the safer alternative to conventional cigarettes, and there is definitely research to support such claims. However, vaping does not come without it’s own concerns.
According to other recent studies reported by Medical News Today, e-cigarettes have been linked to an increased cardiovascular risk and abnormal cardiac activity. Such studies have concluded that the nicotine in e-cigarette liquids is the likely cause.
The latest study out of Kentucky simply provides further evidence of how e-cigarettes might harm the heart, but rather than nicotine, chemical flavourings are the most recent cause for concern.
