| Abstract: | Investigation of preventive measures for hypertension and atherosclerosis is a geriatric medicine priority. While the causes of both isolated systolic hypertension and conventional systolic and diastolic hypertension in the elderly are well defined, the benefits of lowering blood pressure are not. Evidence to support the treatment of symptomatic hypertension is convincing for men 60 years of age; it is not for women in this age group. The need to treat hypertension, particularly isolated systolic hypertension in patients above 75 years old, is still not resolved. Isolated systolic hypertension in older patients is at least as strong a risk factor for cardiovascular disease as is diastolic hypertension. Ongoing trials may answer these questions; in the meantime, drug therapy in this group will vary widely. The elderly hypertensive is more likely than the younger hypertensive to have other diseases; diagnosis of these disorders is crucial. Hypertension arising de novo late in life warrants a search for underlying and possibly remedial causes. Antihypertensive drug therapy to relieve symptoms is difficult to justify, because most elderly hypertensive patients are asymptomatic; however, it has been shown to delay morbid and fatal complications of hypertension. Appropriate therapy for the elderly hypertensive must be individualized and should be associated with few or no side effects. The thiazides are the preferred diuretics for long-term treatment of hypertension in the elderly. Beta blockers are attractive because they are cardioprotective, counter the end organ effect of catecholamines and reduce angina; however, some decrease cardiac output, increase peripheral resistance, decrease renal blood flow and cause fatigue.(ABSTRACT TRUNCATED AT 250 WORDS) |
