Perspective on hypertension in the elderly.
More than half of elderly men and women have hypertension, leading to a significant risk of increased morbidity and mortality. The cause of hypertension in this age group is unknown. Left ventricular hypertrophy is frequently present, often associated with diastolic dysfunction. Systolic hypertension in the elderly increases the risk of cardiovascular disease, but there are no good data to show that the treatment of isolated systolic hypertension reduces the morbidity or mortality. Good evidence indicates that antihypertensive treatment in this group decreases cardiovascular morbidity and mortality up to age 80, so most elderly hypertensive patients should be treated. An empiric trial of nonpharmacologic therapy can be initiated in those with mild hypertension and no cardiovascular disease, but most patients will require drug therapy. Most elderly hypertensive patients have accompanying illnesses for which they may or may not be taking medications. Some antihypertensive drugs exacerbate coexisting diseases while others augment treatment regimens. Similarly, drugs may interact in a beneficial or adverse way. Finally, drug metabolism is altered by age, leading to problems with toxicity or diminished efficacy. The choice of medication should be based on all such considerations, including the cost and convenience of the drugs available.
