Description
Estimated cost for 24-hour Ambulatory Blood Pressure Monitoring at general public hospitals in China is about ¥140-320, and at Grade 3A hospitals about ¥200-400, varying by hospital tier and region.
Main Uses
The main clinical uses of 24-hour ambulatory blood pressure monitoring are to diagnose and manage hypertension, assess the effectiveness of antihypertensive therapy, identify white coat hypertension (elevated BP in a clinical setting but not in daily life), detect masked hypertension (normal BP in a clinical setting but elevated in daily life), and evaluate nocturnal BP patterns which may indicate cardiovascular risk.
Normal Range
The normal range for 24-hour ambulatory blood pressure monitoring (ABPM) typically includes: an average daytime systolic blood pressure of less than 135 mmHg and diastolic blood pressure of less than 85 mmHg; an average nighttime systolic blood pressure of less than 120 mmHg and diastolic blood pressure of less than 70 mmHg. The overall 24-hour average should be below 130/80 mmHg.
Low Values - Possible Causes
Possible causes of low values in 24-hour ABPM include: dehydration, heart problems such as bradycardia or heart block, endocrine disorders like adrenal insufficiency, severe infections leading to septic shock, and certain medications that can lower blood pressure excessively.
High Values - Possible Causes
Common reasons for high values in 24-hour ABPM include: primary hypertension, secondary hypertension due to conditions like kidney disease or thyroid disorders, obesity, excessive salt intake, lack of physical activity, and stress or anxiety. Some medications and substances, such as non-steroidal anti-inflammatory drugs (NSAIDs) and caffeine, can also contribute to elevated readings.
