Treatment of Hypertension
CME credit available from Harvard Medical School through November 2019.
The goal of this program is to update prescribers on the most recent evidence regarding treatment of hypertension, selection of blood pressure goals based on patient characteristics, and management of hypertension with non-pharmacologic and pharmacologic interventions.
Hypertension is common with nearly 1 in 3 Americans receiving this diagnosis. While 77% of hypertensive patients are being treated, only 54% of these patients are controlled.1 Controlling blood pressure is a critical step to prevent stroke, coronary heart disease, heart failure, and cardiovascular death.2 The most recent hypertension guideline was released over a decade ago. With new evidence, and in the absence of an updated consensus guideline, selecting blood pressure targets in the management of hypertension has become more complex.
The first and most important step in managing hypertension is to select the blood pressure target. A new landmark study (SPRINT)3 found intensive blood pressure lowering (BP <120/90 mm Hg) in patients at increased risk of cardiovascular (CV) events prevented more CV events than standard blood pressure control (SBP <140 mm Hg). Combining the findings of SPRINT with earlier studies, the resulting figure below provides guidance to select a blood pressure target based on clinical trial evidence.
Selecting a blood pressure target based on current evidence4-8
For older patients in the SPRINT study, the benefit of intensive blood pressure control was greater than in younger patients.
Intensive BP lowering to a goal of <120/90 mm Hg, prevented more CV events in patients age 75 and over than in younger patients with increased CV risk
In these older patients, side effects were common, but not different between the intensive and standard BP goals.
Key considerations for managing hypertension:
- Counsel patients on a low-salt diet.
- Ensure patient adherence to prescribed medication.
- Intensify therapy for patients who are not at goal.
Achieving the blood pressure target is more important than the drug class used to get there.9
When selecting an antihypertensive medication, begin with a thiazide-type diuretic, angiotensin converting enzyme inhibitor (ACEI), angiotensin receptor blocker (ARB), or a calcium channel blocker (CCB). When dual therapy is required, the combination of an ACEI + CCB prevented more CV events than an ACEI + thiazide.10 The algorithm below suggests a strategy for managing therapy, continually reassessing treatment effect to achieve the blood pressure goal.
