Vaping 'risks heart damage and not safe substitute for cigarettes'
E-cigarettes could damage the heart, scientists have concluded as they urge health authorities to stop recommending vaping.
Researchers looked at 38 studies into the cardiovascular impact of vaping and found worrying signs of damage in nearly three-quarters of tests.
When they discounted trials funded by the tobacco industry - or where the scientists involved had conflicts of interest - the number rose to 90pc.
Human studies in the new analysis showed that vaping led to an increase in heart rate, blood pressure, arterial stiffness and platelets, which cause clotting.
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.
