Indications for ambulatory BP monitoring

Confirm the diagnosis of hypertension.

Detect the white coat hypertension.

Detect the masked hypertension in individuals with high-normal OBP or normal BP with target organ damage or high cardiovascular risk.

Detect the hypertension in cases of marked BP discrepancy between OBP and home BP.

Assess the dipping patterns (dipper, nondipper, reverse dipper, and extreme dipper), nocturnal hypertension, morning hypertension, and morning surge.

Assess the cause of secondary hypertension (e.g., sleep apnea).

Assess labile hypertension or hypotension (postural, postprandial, and drug-induced hypotension).

Assess the BP caused by autonomic dysfunction.

Assess the short-term BP variability.

Monitoring the efficacy of antihypertensive medications in treated patients.

Assess the white coat effect and masked uncontrolled hypertension.

Assess symptomatic hypotension due to excessive treatment.

Ensure 24-hour BP control (particularly in high-risk individuals and pregnant women).

Confirm the diagnosis of resistant hypertension.

Assess accurate BP measurement for risk assessment.
