Ambulatory Blood pressure monitoring (ABPM)
Ambulatory blood pressure monitoring (ABPM)
How is ABPM done?
How is ABPM different from normal Blood pressure evaluation?
Why do I need ABPM?
Ambulatory BP monitoring can find out abnormal variations in BP that may go unnoticed when it is measured at the doctor’s office. It is very useful in detecting white coat hypertension, sustained hypertension and masked hypertension:
White coat hypertension: Some people have elevated BP readings when their BP is measured at the doctor’s clinic or hospital. This is called “white coat hypertension.” It can result in misdiagnosis of patients whose BP is otherwise normal. White coat hypertension has been observed in 15%-30% of patients with high BP readings. Therefore, when ABPM yields BP readings within the normal range, those patients do not need to take antihypertensive medicines.
Sustained hypertension: If BP readings are elevated whether the patient is in the clinic or at home, it is called sustained hypertension. This condition has been linked to an increased risk of heart and kidney diseases.
Masked hypertension: This condition happens when a patient’s blood pressure is normal at the clinic/ hospital but is elevated at home. It may occur in around 20% of people who are taking medicines for hypertension.
