Hypertension is very common, occurring in over 50% of older people, and is a major risk factor for stroke and ischaemic heart disease. Based on systematic reviews there is evidence to show that drug treatment of hypertension in older people saves lives and prevents unnecessary morbidity. There is also strong evidence to support the use of diuretics as first line agents. Quality of life does not appear to be reduced by antihypertensive drug therapy, although more high quality research is needed. Through the use of drug treatment older people with hypertension can continue to contribute to society and live active lives.
