24h Ambulatory BP Monitor — large international cohorts and a 2025 patient-level meta-analysis consistently show 24-hour and nighttime ambulatory readings predict death and cardiovascular events better than office measurements, and US guidelines recommend confirming hypertension out-of-office. By capturing daytime, nighttime, and 24-hour average blood pressure, as well as patterns such as nocturnal dipping and short-term variability, ABPM provides out-of-office readings widely regarded as the reference standard for blood pressure assessment.

A 24-hour ambulatory blood pressure monitor (ABPM) is a portable, automated device that records blood pressure at regular intervals over a full day and night while a person carries out normal activities and sleeps. By capturing daytime, nighttime, and 24-hour average blood pressure, as well as patterns such as nocturnal dipping and short-term variability, ABPM provides out-of-office readings widely regarded as the reference standard for blood pressure assessment. It can identify white-coat hypertension (elevated only in the clinic) and masked hypertension (elevated only outside the clinic), which single clinic readings miss, and major guidelines, including the US Preventive Services Task Force and the 2025 AHA/ACC hypertension guideline, recommend confirming a hypertension diagnosis with out-of-office measurement before treatment.
Large prospective cohorts and pooled analyses of more than 10,000 people show that ambulatory blood pressure, especially the nighttime and 24-hour average, predicts cardiovascular events and all-cause and cardiovascular mortality more strongly than clinic measurement, and that masked hypertension and high nighttime pressure carry substantial risk while white-coat hypertension carries comparatively lower risk; the more of the day readings stay within guideline target ranges, the lower the observed risk. Blood pressure variability and non-dipping also track with worse outcomes, though dipping status is only modestly reproducible and randomized trials proving that ABPM-guided treatment improves outcomes are still lacking — the benefit comes from better hypertension management, not the device itself. This evidence concerns ambulatory blood pressure and its measurement as a biomarker of cardiovascular risk, not this specific commercial monitor device.

“long term variability in blood pressure is associated with cardiovascular and mortality outcomes”
“long-term systolic blood pressure variability is associated with all-cause and cardiovascular mortality”
“These results have 2 important clinical messages: ambulatory measurement of blood pressure is superior to clinic measurement in predicting cardiovascular mortality, and nighttime blood pressure is the most potent predictor of outcome.”
“Nighttime BP levels and a riser pattern were independently associated with the total cardiovascular event rate, in particular for HF. These findings suggest the importance of antihypertensive strategies targeting nighttime systolic BP.”
“ASDPRI is an ambulatory blood pressure-derived biomarker that strongly predicts future CV events, stroke, and all-cause mortality. These findings suggest that this index may be useful for risk stratification purposes.”
“ABPM performed during treatment adds prognostic significance on the development of cardiovascular events in high-risk hypertensive patients. Among different ABPM-derived values, night-time SBP is the most potent predictor of outcome.”
