[Home self-measurements of blood pressure and relationship with diagnosis of hypertension and target organ damage: comparative study with ambulatory monitoring].

Background: 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.

Patients And Method: 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.

Results: 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.

Conclusions: 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.
