Managing hypertension: drugs, life-style manipulation or benign neglect? Medical, ethical and economic considerations.
Antihypertensive drugs have been of major benefit to people with moderate or severe hypertension and have contributed enormously to fundamental physiological knowledge. Antihypertensive therapy in milder hypertension reduces the incidence of stroke by 40% or more, may reduce myocardial infarction and prevents progression to more severe hypertension or heart failure but is being criticised as not cost-effective. Much of this criticism is based on deductions from inappropriate data. Nevertheless, it is likely that money is in some cases being wasted on the treatment of people who were not truly hypertensive in the first place. It is also likely that drug dosage is often unnecessarily high. Clearly it is vital that treatment is delivered as economically as possible. A reduction in the prevalence of hypertension would be the best way to reduce costs. Obesity and a high alcohol intake are associated with a higher blood pressure at any age. A high salt intake throughout life appears to be associated with a rise in blood pressure in the second half of life and may well be the main factor in hypertension. A radical rethinking of the method of pricing of medical care should be considered, so as to provide incentives to people to adopt life-style measures that lead to avoidance of hypertension (and other cardiovascular risk factors) or, in established hypertension, to a reduction in the need for medication.
