E-cigarettes could damage the heart, scientists have concluded, and they have urged authorities to stop recommending vaping, reports the Irish Independent.
Researchers looked at 38 studies into the cardiovascular impact of vaping and found worrying signs of damage in nearly three-quarters of tests, writes Sarah Knapton in the article originally published in The Telegraph.
When they discounted trials funded by the tobacco industry – or where the scientists involved had conflicts of interest – the number rose to 90%.
Human studies in the new analysis show that vaping led to an increase in heart rate, blood pressure, arterial stiffness and platelets, which cause clotting, the Irish Independentarticle says.
It also increased free radicals and reduced antioxidants, raising the risk of plaque build-up in the artery walls, which can lead to a heart attack.
