Abstract
in English, Spanish

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.

Objetivo: Analizar las diferencias de la presión de pulso (PP) en pacientes hipertensos diabéticos tipo 2 y no diabéticos utilizando la medida de la presión arterial (PA) clínica (PAC) y la monitorización ambulatoria de la presión arterial (MAPA) de 24 h en atención primaria (AP).

Diseño: Estudio descriptivo transversal.

Emplazamiento: Atención primaria.

Participantes: Un total de 163 hipertensos de una muestra no seleccionada de pacientes, en la que se incluyó al primer paciente que acudió a la consulta programada cada día.

Mediciones principales: Registros de PAC (esfigmomanómetro de Hg) y MAPA. Se consideró PP elevada a la diferencia entre la PA sistólica y diastólica superior a 60 mmHg.

Resultados: El 31,3% (51 pacientes) era diabético. La PP clínica media fue de 75,9 ± 18,4 mmHg en diabéticos y 64,5 ± 18,9 mmHg en no diabéticos (p < 0,001) y la PP ambulatoria media fue de 61,4 ± 13,8 mmHg en diabéticos y 53,5 ± 11 mmHg en no diabéticos (p < 0,001), correlacionándose la PP clínica y ambulatoria con la edad. La PP clínica y ambulatoria resultaron elevadas en el 63,8 y 57,4%, respectivamente, de los hipertensos diabéticos. El modelo de regresión logística demostró una mayor probabilidad de PP elevada en los mayores de 64 años y en los que presentaban hipertensión arterial sistólica aislada o diabetes mellitus.

Conclusiones: Encontramos importantes diferencias entre la PP clínica y la ambulatoria, así como entre la PP de la población hipertensa diabética y no diabética. La PP ambulatoria elevada en los pacientes hipertensos se asocia con la diabetes y la hipertensión sistólica aislada.
