Abstract Background: Hypertension (HTN) is a major risk factor for cardiovascular morbidity and mortality and therefor, its diagnosis and follow up by the different methods of BP measurements are held to get the most accurate values of BP for each patient. Purpose: to compare the accuracy and degree of agreement of the automated sequential blood pressure(aSqBP)with the office blood pressure (OBP) and the ambulatory blood pressure (ABPM) readings, and whether the ABPM can replace the day-time ABPM. Methods:This cross sectionalobservational study enrolled 64 patients ,known hypertensive or to check up their BP, coming to Kasr ElAiniSpecialized hypertension clinic. Full medical history was taken. Full clinical examination, ECG and laboratory for kidney functions, were done for each patient. Blood pressure of the patient was recorded in Office BP, aSqBP and ABPM. Results: The patients age ranged between 20 and 85 years, with a mean± SD age of 50.0 ± 15.0 years.There were 53.1% females.The OBP readings were higher than the daytime ABPM asthere was a statistically significant difference between OBP and ABPM daytime SBP (mean ±SD was142.7± 15.5 versus 135.8± 15.7 mmHg, p< 0.0001), and daytimeDBP (mean ±SD was 88.5±12.3 versus 82.1± 13.7 mmHg, P <0.0001).The aSqBP has a strong positive correlation with daytime ABPM asr= 0.74 and P<0.0001.There is a moderate degree of agreement between aSqSBP anddaytime systolic ABPM and a fair degree of agreement between aSqBP and the daytime ABPM. Conclusion:The aSqBP measurement is more accurate than office BP measurement , however it can reflect the daytime ABPM moderately for the SBP& fairlyfor the DBP. ABPM is better than both of them, and is still the reference in cases with labile HTN, white coat HTN and marked BP variability |
