Essential hypertension: cost-effective evaluation and treatment

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.
