Objetivo

Averiguar qué variables influyen en las alteraciones de la distensibilidad arterial en los sujetos hipertensos mediante medición de la velocidad de onda de pulso (VOP).

Diseño

Estudio descriptivo transversal.

Ámbito

Centro de salud rural.

Sujetos

Ciento cincuenta y seis pacientes hipertensos menores de 76 años, seleccionados por medio de muestreo aleatorio simple entre los incluidos en el registro de hipertensión arterial (HTA).

Mediciones e intervenciones

Determinamos grado de HTA, años de evolución, tensión arterial sistólica (TAS) y diastólica (TAD), índice de masa corporal (IMC), glucemia, existencia de dislipemia, diabetes o intolerancia a la glucosa, hábito tabáquico, edad, sexo y VOP (medición automática por ordenador). Realizamos análisis multivariante mediante regresión lineal múltiple, siendo la variable dependiente la VOP y las independientes edad, TAS, TAD, IMC, años de evolución de la HTA, colesterol, triglicéridos y glucemia.

Resultados

Edad media 62,5 (DE, 8,8); el 28,2% varones; TAS media, 153 (DE, 18,9); TAD media, 87 (DE, 10,3); media de años de evolución, 10,4 (DE, 7,4); IMC medio, 31,2 (DE, 4,9); hiperglucemia, 24,4%; glucemia media, 111,3 (DE, 29); VOP media, 11,82 (DE, 2,37). La VOP era superior a las cifras normales teóricas en un 69,2%. La regresión lineal múltiple mostró que las variables que influyen significativamente en la VOP son edad, TAS e hiperglucemia.

Conclusiones

La mejora de la distensibilidad arterial puede obtenerse controlando la TAS, puesto que los otros factores relacionados son inmodificables.

Objective

To find out what variables affect changes in arterial compliance in subjects with hypertension by measuring their pulse wave velocity (PWV).

Design

Cross-sectional, descriptive study.

Setting

Rural health centre.

Patients

156 hypertense patients under 76, chosen by simple random sampling from those on the hypertension register.

Measurements and interventions

We determined the degree of hypertension, years of evolution, systolic pressure (SBP), diastolic pressure (DBP), body mass index (BMI), glucaemia, whether lipaemia existed, diabetes or glucose intolerance, tobacco habit, age, sex and PWV (measured automatically by computer).We performed multivariate analysis by means of multiple linear regression, with PWV as the dependent variable, and age, SBP, DBP, BMI, years of evolution of hypertension, cholesterol, triglycerides and glucaemia as independent variables.

Results

Mean age 62.5 (SD 8.8). 28.2% male. Mean SBP 153 (SD 18.9). Mean DBP 87 (SD 10.3). Mean years of evolution 10.4 (SD 7.4). Mean BMI 31.2 (SD 4.9). Hyperglucaemia 24.4%. Mean glucaemia 111.3 (SD 29). Mean PWV 11.82 (SD 2.37). PWV was above the theoretically normal figures in 69.2% of cases. Multiple linear regression showed that the variables which affected PWV significantly were age, SBP and hyperglucaemia.

Conclusions

Arterial compliance can be improved by controlling SBP, given that the other related factors cannot be changed.
