Treatment of hypertension in the elderly.

Hypertension is a common condition among older people in most developed countries, and is a very important, if not the most important, risk factor for all subtypes of vascular disease and death. Many clinical trials in older people have demonstrated significant reductions in myocardial infarctions and strokes when antihypertensive drugs are provided. Lifestyle modifications are still recommended because they can lower a surrogate end point--blood pressure--but there are no data showing they reduce event rates. It is not appropriate to limit the choice of initial drug for hypertensive older individuals to a single class of agents, since so many older people have other medical problems that affect this decision. Monotherapy with an alpha blocker, however, is no longer recommended, even for men with hypertension and benign prostatic hypertrophy, as doxazosin was associated with a higher rate of cardiovascular events in the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial. The classic strategy of an initial diuretic (for at least 1 month) will likely be verified by the final results of ongoing randomized trials, expected in 2003. Until then, this strategy is effective, inexpensive, and unlikely to cause many adverse effects. Probably the most important exhortation, however, should be to achieve the blood pressure goal appropriate for the patient's risk status. Numerous clinical trials in older hypertensive patients have shown that more benefits accrue when the goal blood pressure is achieved than if a specific antihypertensive agent is chosen as initial therapy. Future cardiovascular risk may be related directly to the blood pressure attained, rather than to how it was attained. (c)2002 CVRR, Inc.
