Abstract:
BACKGROUND AND OBJECTIVE:Hypertension is highly prevalent in the very elderly. We studied control rates of hypertension according to clinic blood pressure (BP) and ambulatory BP monitoring (ABPM) in treated hypertensives aged > or =80 years. PATIENTS AND METHOD:Data came from the Spanish Society of Hypertension ABPM Registry (CARDIORISC - MAPAPRES project), which comprises a nation-wide network of more than 1,000 physicians sending standardized ABPM registries via web. Between June 2004 and April 2007 we obtained a 33.829-patient database. Control of hypertension was defined at the clinic when office BP was <140/90mmHg and at the ABPM when mean BP during the 24-h period was <130/80mmHg. RESULTS:We identified 2,311 patients (6.8%) aged > or =80 years. Mean age (SD) was 83.1 (3.2) years and 63% were women. Control of clinic BP was observed in 21.5% of cases (95%CI: 19.1-23.9) and control of 24-h BP in ABPM was 42.1% (95%CI: 39.7-45.3). Prevalence of masked hypertension was 7.0% (95%CI: 6.0-8.0) and prevalence of office-resistant control (white coat) was 27.6% (95% CI: 25.7-29.4). Diabetes, kidney disease, and duration of hypertension were associated with lack of control in ABPM. CONCLUSIONS:In very old hypertensives, control of clinic BP was 21.5% but ambulatory-based hypertension control was 42.1%. Physicians should be aware that the likelihood of misestimating BP control is high in these subjects. A wider use of ABPM in the elderly with hypertension should be considered.
