The diagnosis of arterial of hypertension (AH) requires an accurate and precise measurement methodology. The habitual techniques overstimate the prevalence of AH and have a poor correlation with organ damage. The objective of the study is to know the associations between self-measurements of blood pressure (BP) at home and target organ damage of AH.
Descriptive study which compare the association of different techniques of BP measurement with the diagnosis of AH and its organ damage. Sampling selection of consecutive cases; we select 64 cases of hypertensives not treated hypertensive patients, older than 18 years. We achieved 3 BP measurements with mercury sphygmomanometer in the office and 20 self-measurements in the morning in the office and 20 self-measurements in the afternon at home with a automatic validated device, Omron 705CP; the same day BP was measured with ambulatory blood pressure measurement (ABPM) of 24 h with a Takeda TM-2420 device; we achieved eye fundus study, microalbuminuria analysis and echocardiogram.
Mean values of office BP was higher than self-measurements at home and ABPM; these techniques had good correlations and concordance between them. The correlation of selfmeasurements at home with LVMI was higher than office BP and similar to ABPM; this correlation is independent of age, sex and body mass index. The best correlation of self-measurements at home with APBM and LVMI was with the mean values of 2nd-6th self-measurements.
A minimum program of self-measurements of BP at home with automatic devices has a prognostic value and relationship with organ damage of AH similar to ABPM.
