Abstract
Lowering alcohol intake reduces blood pressure and hence cardiovascular risk. However, abstainers have an increase in cardiovascular risk and the advice to reduce intake to low levels may not be sound. This review examines the effects of lowering alcohol consumption in terms of blood pressure and coronary heart disease (CHD). The relationship between both CHD and stroke and alcohol consumption, and the benefits and disadvantages of alcohol consumption in the general population, are discussed. Where available, the results of large meta-analyses are reported. It is concluded that the hypertensive patient over the age of 60 who drinks over 16 drinks per week should be advised to reduce his or her alcohol intake but a daily drink may be advisable and the patient should not stop drinking entirely. It is not suggested that the non-drinker should start drinking, but most hypertensives are over the age of 60 when community studies suggest that drinking alcohol does more good than harm.
