The vast majority of hypertensive patients will be detected during an asymptomatic screening during some contact with the medical system. The US Preventive Services Task Force (USPSTF) has recommended annual screening for adults aged ≥40 years or for those at increased risk for high blood pressure (BP) (high-normal BP, overweight or obese, or African-American). Adults aged 18-39 years with normal BP without other risk factors were advised to be re-screened every 3-5 years.[67]US Preventative Services Task Force. Hypertension in adults: screening. Apr 2021 [internet publication].

The American College of Cardiology (ACC)/American Heart Association (AHA) guideline, however, recommends annual screening in all patients with normal BP.[2]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.

Measurements should be obtained outside of the clinical setting (ambulatory blood pressure monitoring [ABPM] or home blood pressure monitoring [HBPM]) to confirm the diagnosis.[2]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.

If a patient has an untreated systolic BP >130 mmHg but <160 mmHg or diastolic BP >80 mmHg but <100 mmHg, it is reasonable to screen for the presence of white-coat hypertension by using either daytime ABPM or HBPM before diagnosis of hypertension.[2]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.

In adults with elevated clinic BP (120-129/<80 mmHg) but not meeting the criteria for hypertension, screening for masked hypertension with daytime ABPM or HBPM is reasonable. Guidelines for other countries may recommend different screening intervals. The 2024 ESC guideline recommends annual screening for individuals with raised BP (120-139 mmHg systolic or 70-89 mmHg diastolic) or for those aged ≥40 years. For individuals aged <40 years with non-elevated BP, screening is recommended at least every 3 years.[1]McEvoy JW, McCarthy CP, Bruno RM, et al. 2024 ESC guidelines for the management of elevated blood pressure and hypertension. Eur Heart J. 2024 Oct 7;45(38):3912-4018.

These screening guidelines are often exceeded, as BP measurement is standard for each encounter in many practice settings. Elevated readings should always be confirmed on a second visit prior to diagnosing hypertension.
