Objective:
To analyse the differences in pulse pressure (PP) between type-2 diabetic and non-diabetic hypertense patients, using clinical blood pressure (CBP) measurement and out-patient blood pressure monitoring (OPBPM) over 24 hours in primary care.
Design:
Cross-sectional descriptive study.
Setting:
Primary care.
Participants:
163 hypertense patients in a random sample, including the first patient of each day with an appointment.
Main Measurements:
CBP (Hg sphygmomanometer) and OPBPM recording. PP was considered high when the difference between systolic and diastolic pressure was over 60 mm Hg.
Results:
31.3% (51 patients) were diabetic. Mean clinical PP was 75.9 +/- 18.4 in diabetics and 64.5 +/- 18.9 mm Hg in non-diabetics (P<.001). Mean out-patient PP was 61.4 +/- 13.8 in diabetics and 53.5 +/- 11 mm Hg in non-diabetics (P<.001), with clinical and out-patient PP correlating with age. Clinical and out-patient PP were high in 63.8% and 57.4%, respectively, of hypertense diabetics. The logistical regression model showed more likelihood of high PP in those over 64 and in those with isolated systolic hypertension and/or diabetes mellitus.
Conclusions:
We found considerable differences between clinical and out-patient PP, and between the PP of the diabetic and non-diabetic population with hypertension. High out-patient PP in hypertense patients is related to diabetes and isolated systolic hypertension.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
