Essential hypertension: cost-effective evaluation and treatment
Insights
Effective hypertension management prioritizes treating essential hypertension over rare secondary causes. Step-wise treatment, often starting with diuretics, is cost-effective and reduces cardiovascular risks.
Area of Science:
- Cardiology
- Public Health
- Pharmacology
Background:
- Hypertension is highly prevalent in the US, incurring significant treatment costs.
- Over-investigation for rare secondary causes of hypertension diverts resources from effective essential hypertension management.
- Treating essential hypertension reduces morbidity and mortality from cardiovascular diseases.
Purpose of the Study:
- To advocate for a cost-conscious approach to hypertension evaluation and treatment.
- To emphasize prioritizing essential hypertension management.
- To outline evidence-based treatment guidelines for hypertension.
Main Methods:
- Review of clinical and epidemiologic studies on hypertension treatment.
- Analysis of cost-effectiveness in hypertension management strategies.
- Guideline formulation for step-wise hypertension therapy.
Main Results:
- Treatment initiation recommended for diastolic blood pressure ≥ 90 mm Hg on three visits.
- Non-pharmacologic therapy suitable for mild hypertension without target organ disease and with good compliance.
- Diuretics are recommended as first-line therapy due to efficacy, convenience, and low cost.
- Beta-blockers are suitable alternatives when diuretics are contraindicated.
- Combination therapy with diuretics and other agents is effective when needed.
Conclusions:
- A cost-conscious strategy focusing on essential hypertension is crucial.
- Step-wise treatment, starting with diuretics or beta-blockers, is effective and economical.
- Appropriate management of hypertension significantly reduces cardiovascular risks and healthcare costs.
Abstract:
The widespread prevalence of hypertension in the United States and the enormous expense and effort associated with its treatment necessitate a cost-conscious approach to evaluation and therapy. In the past, we have devoted too many resources to testing for rare diseases suspected of causing hypertension when it has been demonstrated that secondary causes are rare. Devoting resources to the effective treatment of essential hypertension itself should be a priority, because such treatment has been shown to reduce morbidity and mortality associated with hypertension and related cardiovascular diseases. Clinical and epidemiologic studies have demonstrated that treatment for hypertension should not be initiated unless diastolic blood pressure readings are 90 mm Hg or greater on three successive office visits. Treatment should be carried out in a step-wise fashion, using a non-pharmacologic approach only in situations in which hypertension is mild, target organ disease is absent, and compliance is favorable. Diuretics should be used as step-one drug therapy in most situations, because they are effective in the majority of patients, convenient to use, easy to titrate, and comparatively inexpensive. They do not cause salt and water retention, and side effects are usually minimal. When the use of diuretics is contraindicated, beta blockers are suitable alternatives, equally effective in most respects. When beta blockers or other non-diuretic drugs are used as step-one therapy and an additional drug is needed, diuretics can be used advantageously in conjunction with the step-one drug.
