Conditions in Which ABPM May Be Particularly Helpful*

ConditionRelevance of ABPM
Secondary hypertensionElevated load, abnormal dipping and variability
Chronic kidney diseasePrevalence of hypertension, masked hypertension, association with target-organ changes and disease progression
Types 1 and 2 diabetes mellitusAbnormal circadian variation, association with microalbuminuria and vascular changes
ObesityMasked hypertension, correlation between BMI and hypertension severity, abnormal dipping, association with target-organ damage
Sleep apneaHypertension severity, abnormal circadian variation
Genetic syndromes
 Neurofibromatosis type 1
 Turner syndrome
 Williams syndrome
Abnormal BP patterns indicating secondary cause of hypertension, especially renal artery stenosis and aortic coarctation
Treated patients with hypertensionResponse to antihypertensive medications and/or lifestyle changes
Hypertension researchReduction in subject number in drug trials
