ABP

Definition & Etymology

ABP is the abbreviation for Ambulatory Blood Pressure. This diagnostic method measures blood pressure at regular intervals over a 24-hour period using a portable device. Monitoring occurs during the patient’s normal activities, providing a profile outside the clinical setting. “Ambulatory” derives from the Latin ambulare (to walk), indicating the patient is mobile during the test.

Clinical Significance

Ambulatory Blood Pressure Monitoring (ABPM) provides a more accurate assessment of a patient’s blood pressure than isolated office readings. It is the standard for diagnosing “white coat hypertension” (elevated BP only in a clinical setting) and “masked hypertension” (normal office BP but elevated elsewhere). By capturing 24-hour patterns, including the critical nocturnal dip, ABPM offers superior prognostic value for cardiovascular events and target-organ damage. It is also vital for assessing the efficacy of antihypertensive therapy.

Related Conditions

ABP monitoring is central to managing Hypertension. It is specifically indicated for suspected White Coat Hypertension, Masked Hypertension, and Resistant Hypertension. As the only method to reliably identify Nocturnal Hypertension, it detects a potent risk factor for adverse outcomes. The procedure also detects episodes of Hypotension in patients with autonomic dysfunction or those on complex medication regimens.

Key Takeaways

• ABP measures blood pressure over 24 hours during a patient’s normal routine, including sleep.
• It is the definitive tool to diagnose white coat and masked hypertension, preventing misclassification.
• The data provides a more accurate assessment of cardiovascular risk and 24-hour drug efficacy.
