Abstract

Background Diagnosis of hypertension is based on office, home and ambulatory blood pressure measurements. The aim of the study was to assess blood pressure in either office and ambulatory measurements taking into consideration time of treatment and antropometric parameters.

Material and methods The study group consisted of 161 patients in average age of 50.3 ± 13.9 years old. All patients underwent ambulatory blood pressure monitoring (ABPM) and office blood pressure measurements in sitting position. We additionally assessed: age, sex, weight, height, waist circumference and presence of hypertension complications.

Results Mean blood pressure in office blood pressure measurements was 143/88 mm Hg and in. ABPM mean 24-hour blood pressure was 134/79 mm Hg — no differences between men and women. Mean blood pressure in office and ambulatory blood pressure measurements were respectively: in newly treated group 133/81 v. 147/93 mm Hg, in group treated less than 1 year 134/79 v. 142/88 mm Hg, in group treated from 2 to 5 years 136/81 v. 142/87 mm Hg and in group treated more than 5 years 134/77 v. 145/89 mm Hg. No differences among groups. Mean blood pressure in office and ambulatory blood pressure measurements were respectively: in obese patients 145/86 v. 136/80 mm Hg, in overweight patients 143/90 v. 134/78 mm Hg and in patients with normal weight 142/90 v. 133/80 mm Hg.

Conclusions Mean blood pressure tends to be higher in office than ambulatory blood pressure measurements. Blood pressure is independent on time of hypotensive treatment. Blood pressure is higher in overweight patients. ABPM tends to be more specific than office blood pressure measurements in assessment of hypotensive treatment efficacy.
