Essential hypertension

Essential hypertension is typically diagnosed by screening of an asymptomatic individual.

Treatment of uncontrolled hypertension reduces the risks of mortality and of cardiac, vascular, renal, and cerebrovascular complications.

Lifestyle changes are recommended for all patients: weight loss, exercise, decreased sodium intake, Dietary Approaches to Stop Hypertension (DASH) diet, and moderation of alcohol consumption.

Choice of drug therapy is often driven by considerations related to comorbid disease, but achievement of blood pressure goal may be accomplished with a variety of therapeutic agent(s).

Essential hypertension is defined as persistently raised blood pressure (BP) with no secondary cause identified.[1]National Heart, Lung, and Blood Institute.

The 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guideline defines hypertension as systolic BP measurement of ≥130 mmHg or diastolic BP measurement of ≥80 mmHg.[3]Whelton PK, Carey RM, Aronow WS, et al. 2017 ACC/AHA/AAPA/ABC/ACPM/AGS/APhA/ASH/ASPC/NMA/PCNA guideline for the prevention, detection, evaluation, and management of high blood pressure in adults: a report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines.

The 2018 European Society of Cardiology (ESC) and European Society of Hypertension (ESH) guideline defines hypertension as office systolic BP ≥140 mmHg and/or diastolic BP ≥90 mmHg, which is equivalent to a 24-hour ambulatory BP measurement average of ≥130/80 mmHg, or a home BP measurement average of ≥135/85 mmHg.[2]Williams B, Mancia G, Spiering W, et al. 2018 ESC/ESH guidelines for the management of arterial hypertension.

The World Health Organization (WHO) recommends starting pharmacologic antihypertensive treatment in patients with a confirmed diagnosis of hypertension and systolic BP of ≥140 mmHg or diastolic BP of ≥90 mmHg.[5]World Health Organization.

BP goals and recommendations continue to evolve in line with new evidence.
