Moderate drinking can lower hazard of heart attack, tells analyse

Drinking in moderation helps protect heart, with analyze find it lowers hazard of many conditions compared with not drinking

Moderate drinking can lower the risk of several heart conditions, according to a study that will further ga the discussion about the health implications of alcohol intake.

The study of 1.93 million people in the UK aged over 30 found that drinking in moderation defined as ingesting no more than 14 divisions of alcohol a week had a protective effect on the heart compared with not drinking.

Previous studies have suggested that alcohol had a positive impact on the levels of good cholesterol in the blood and proteins links with blood clotting.

The research, published in the British Medical Journal, found that moderate drinkers were less likely than non-drinkers to turn up at their doctor with angina, heart attack, heart failure, ischaemic stroke, circulation problems caused by a build-up of fat in the arteries and aortic aneurysm than non-drinkers.

But the research found that heavy drinking more than 14 divisions increased the risk of heart failure, cardiac arrest, ischaemic stroke and circulation problems caused by fatty arteries.

The writers of such studies, from the University of Cambridge and University College London, welcomed the findings but cautioned: While we found that moderate drinkers were less likely to initially present with several cardiovascular disease than non-drinkers, it could be argued that it would be unwise to encourage someones to take up drinking as a means of lowering their risk.

This is because there are arguably safer and more effective ways of reducing cardiovascular danger, such as increasing physical activity and smoking cessation, which do not incur increased risks of alcohol-related damage such as alcohol dependence, liver illness and cancer.

Moderate alcohol consumption has long been associated with a lower hazard of heart disease compared with abstinence or heavy drinking but the authors described their study as the most comprehensive to date on the relationship.

Non-drinkers were separated from former and occasional drinkers. With previous analyzes, fears have been raised that people who have stopped drinking due to illness could have skewed results among non-drinkers.

An independent its consideration of evidence, which formed the basis for last years change in the official advice on alcohol consumption, lowering the recommended restriction to 14 divisions a week for both men and girl, found that the benefits of drinking for heart health only apply for women aged 55 and over and the greatest benefit is considered when they restriction their intake to about five divisions a week, equivalent to about two standard glasses of wine.

The study found that heavy drinking resulted in an increased risk of a range of heart diseases compared with moderate drinking, but carried a lower hazard of heart attack and angina.

The writers cautioned that this did not mean they were less likely to experience a heart attack in future, just that they were less likely to present these conditions at first diagnosis, compared with moderate drinkers. Also, as the study is observational , no firm conclusions can be drawn about cause and effect.

One unit of alcohol is about equal to half a pint of ordinary strength brew, lager or cider( 3.6% alcohol by volume) or a small pub measure( 25 ml) of spirits. There are one and a half units of alcohol in a small glass( 125 ml) of ordinary strength wine( 12% alcohol by volume ).

Dr James Nicholls, the director of research and policy development at Alcohol Research UK, said that given the increased risk of other health conditions from drinking, moderate alcohol consumption within existing guidelines was unlikely to curtail or lengthen life expectancy overall.

While the findings provide persuading proof for protective impacts, the authors sensibly point out that the matter is doesnt entail it would be wise to take up drinking in order to lengthen ones life not least because any protective consequences tend to be cancelled out by even occasional bouts of heavier drinking, he told.

There are better ways to strengthen the heart such as exercise and good diet. All things being equal and given the increased risk of suffering other health conditions linked to any sum of alcohol intake if you drink within the existing guidelines it is unlikely that alcohol will either lengthen or abbreviate your life.
