Women who drink above the recommended level of alcohol can increase the risk of developing heart disease, according to research by University College London. A study of more than 3,000 women found those who exceeded 21 units a week increased their risk of coronary heart disease by 57%. However, those who did not drink at all had an 80% increased risk of heart disease compared with those who had a couple of drinks a week. Dr Annie Britton, who co-authored the study, said: "This study only looks at heart disease. If we also looked at things like cirrhosis and accidents caused by drinking we would be quite staggered by what is going on. "The large amount of drinking among young women seems to be quite a new phenomenon. We are not yet seeing the long-term effects and it could be 20 years before we know what effect it has had."
