Is asymptomatic markedly elevated blood pressure (hypertension) without evidence of target organ damage an acceptable classification?

From the Guidelines

No, the classification "Asymptomatic markedly elevated blood pressure without evidence of target organs" is not an acceptable classification in 2025. Current hypertension guidelines have moved away from this terminology in favor of more specific staging based on blood pressure measurements and cardiovascular risk assessment, as seen in the 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 1. The preferred classification system categorizes hypertension into stages (Stage 1: 130-139/80-89 mmHg, Stage 2: ≥140/90 mmHg) while separately noting the presence or absence of target organ damage and other cardiovascular risk factors. This approach allows for more personalized treatment decisions. Even patients with severely elevated blood pressure who appear asymptomatic may have subclinical organ damage that requires evaluation with appropriate testing, including assessment of kidney function, urinalysis, electrocardiogram, and sometimes echocardiography or retinal examination. Some key points to consider in the management of asymptomatic hypertension include:

• The importance of overall cardiovascular risk assessment, rather than just blood pressure numbers, in guiding treatment decisions
• The potential for subclinical organ damage, even in asymptomatic patients, and the need for evaluation with appropriate testing
• The lack of evidence supporting the use of immediate pharmacologic intervention in asymptomatic patients without target organ damage, as noted in the 2006 clinical policy on the evaluation and management of adult patients with asymptomatic hypertension in the emergency department 2. The current approach emphasizes that treatment decisions should be based on overall cardiovascular risk rather than blood pressure numbers alone, recognizing that organ damage can occur even before symptoms develop, making the "asymptomatic" designation potentially misleading for clinical decision-making. Key considerations in the evaluation of patients with asymptomatic hypertension include:
• A focused history and physical examination to detect signs and symptoms of end-organ damage
• Screening for target organ damage, including urinalysis, serum creatinine level, ECG, and chest radiography, although the utility of these tests in the emergency department setting is limited 2. In summary, the classification "Asymptomatic markedly elevated blood pressure without evidence of target organs" is not an acceptable classification in 2025, and treatment decisions should be based on overall cardiovascular risk assessment and evaluation for subclinical organ damage.

From the Research

Classification of Asymptomatic Markedly Elevated Blood Pressure

• The classification of asymptomatic markedly elevated blood pressure without evidence of target organs is a recognized condition in the medical field 3, 4, 5, 6, 7.
• This condition is often referred to as severe asymptomatic hypertension, which is defined as severely elevated blood pressure (180 mm Hg or more systolic, or 110 mm Hg or more diastolic) without symptoms of acute target organ injury 3, 6.
• The management of severe asymptomatic hypertension typically involves gradual reduction of blood pressure over several days to weeks, rather than aggressive lowering of blood pressure 3, 4, 6.

Acceptability of the Classification in 2025

• Although the studies provided are from earlier years (2010-2018), the principles of managing asymptomatic markedly elevated blood pressure remain relevant today 3, 4, 5, 6, 7.
• The classification and management of severe asymptomatic hypertension are based on evidence-based recommendations and guidelines from reputable medical organizations, such as the American College of Emergency Physicians and the American Family Physician 3, 5, 6.
• Therefore, the classification of asymptomatic markedly elevated blood pressure without evidence of target organs is still an acceptable classification in 2025, as it is based on established medical knowledge and guidelines 3, 4, 5, 6, 7.

Key Considerations

• It is essential to differentiate between hypertensive emergency and severe asymptomatic hypertension, as the management and treatment approaches differ significantly 3, 4, 6.
• Patients with severe asymptomatic hypertension often have preexisting poorly controlled hypertension and can usually be managed in the outpatient setting 3, 4, 6.
• The goal of treatment is to gradually reduce blood pressure over several days to weeks, rather than achieving rapid blood pressure control 3, 4, 6.
