Hypertension in elderly patients. The special concerns in this growing population.
Hypertension is quite common in the elderly population. Isolated systolic hypertension and diastolic hypertension are associated with cardiovascular complications. Like younger patients, the elderly may have labile hypertension. On the other hand, pseudohypertension, auscultatory gap, and postural hypotension are peculiar to the elderly. Obesity, atherosclerosis, arteriosclerosis, baroreceptor insensitivity, decline in renal function, physical inactivity, and insomnia are factors that can lead to or aggravate hypertension in older patients. Secondary hypertension should be suspected if elevated blood pressure first appears late in life or becomes resistant to previously adequate treatment. Spontaneous hypokalemia can indicate primary aldosteronism. Elevation in the serum creatinine level of a patient taking an angiotensin-converting enzyme (ACE) inhibitor suggests bilateral renovascular hypertension. The goal of antihypertensive therapy is to prevent morbidity, disability, and death from complications and to maintain quality of life. Psychosocial factors may play an important role in controlling hypertension. Nonpharmacologic treatment, such as weight loss, salt restriction, and exercise, should always be tried prior to and in conjunction with medical therapy. Antihypertensive drugs often cause side effects and should be prescribed with caution. Always start with a low dose and gradually increase it if necessary. All drugs that reduce blood pressure in the younger individual also work in the elderly. ACE inhibitors and calcium blockers are particularly useful because of their low incidence of adverse effects.
