Ambulatory Blood Pressure: What is Ambulatory Blood Pressure?



ambulatory blood pressureThe full name is noninvasive blood pressure monitoring (ABPM), which continuously records daytime and nighttime blood pressure required by the design mode through the examined blood pressure recorder, thus avoiding the objective difference between single blood pressure measurement and "white coat phenomenon". It is helpful to screen critical and mild hypertension, evaluate the antihypertensive effect of antihypertensive drugs, explore the degree of target organ damage and estimate the prognosis, etc.

Compared with occasional blood pressure measurement, ambulatory blood pressure has the following advantages:

(1) Eliminate the chance of accidentally measuring blood pressure, emotions, exercise, diet, smoking, drinking and other factors affect blood pressure, and reflect blood pressure more objectively and truly.

(2) Ambulatory blood pressure can obtain more blood pressure data, which can actually reflect the change law of blood pressure throughout the day.

(3) For the early asymptomatic patients with mild hypertension or borderline hypertension, the detection rate is increased and they can be treated in time.

(4) Ambulatory blood pressure can guide drug treatment. In many cases, it can be used to determine the therapeutic effect of drugs, help select drugs, adjust the dosage and time of administration.

(5) Determine whether the target organs (organs susceptible to hypertension) of hypertensive patients are damaged. In hypertensive patients with myocardial hypertrophy, fundus dynamic vascular disease, or altered renal function, diurnal differences were small.

(6) to predict the time of sudden onset of cerebrovascular disease in one day. When blood pressure suddenly rises in the morning, it is possible to have cardiovascular and cerebrovascular diseases.

(7) Ambulatory blood pressure is of great significance in judging prognosis. Compared with conventional blood pressure, patients with high 24-hour blood pressure had higher rates of mortality and first cardiovascular disease than patients with low 24-hour blood pressure. Especially under the age of 50, diastolic blood pressure <16.0kPa(105mmHg) and no cardiovascular disease in the past, the measurement of ambulatory blood pressure is more meaningful, it can guide drug treatment and predict the onset of cardiovascular disease.
