Hypertension in elderly patients. The special concerns in this growing population
1Department of medicine, Medical College of Wisconsin, Milwaukee.
Insights
Hypertension is common in older adults, with unique challenges like pseudohypertension. Effective management involves lifestyle changes and cautious medication, prioritizing quality of life and preventing complications.
Area of Science:
- Gerontology
- Cardiology
- Internal Medicine
Background:
- Hypertension is prevalent in the elderly, presenting unique conditions such as pseudohypertension and postural hypotension.
- Factors like atherosclerosis, obesity, and declining renal function contribute to hypertension in older individuals.
- Secondary hypertension requires suspicion in late-onset or treatment-resistant cases, with specific indicators like hypokalemia or elevated creatinine with ACE inhibitors.
Purpose of the Study:
- To review the complexities of hypertension in the elderly.
- To highlight peculiar conditions and contributing factors in older hypertensive patients.
- To outline therapeutic goals and strategies for managing hypertension in the elderly.
Main Methods:
- Literature review of hypertension in the elderly population.
- Discussion of specific geriatric hypertensive conditions and risk factors.
- Analysis of diagnostic clues for secondary hypertension.
- Overview of non-pharmacologic and pharmacologic treatment approaches.
Main Results:
- Elderly hypertension presents unique challenges including labile hypertension, pseudohypertension, and postural hypotension.
- Atherosclerosis, obesity, reduced renal function, and inactivity are key aggravating factors.
- Diagnostic indicators for secondary hypertension include late onset, treatment resistance, hypokalemia, and creatinine elevation with ACE inhibitors.
- Non-pharmacologic interventions (weight loss, salt restriction, exercise) are crucial adjuncts to pharmacotherapy.
- Antihypertensive drugs are effective in the elderly, with ACE inhibitors and calcium channel blockers noted for favorable side effect profiles when initiated cautiously at low doses.
Conclusions:
- Managing hypertension in the elderly requires addressing unique physiological changes and potential complications.
- A combined approach of lifestyle modification and judicious pharmacotherapy is essential.
- Careful drug selection and titration are vital to maximize benefits and minimize adverse effects, maintaining quality of life.
Abstract:
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.
