Ambulatory blood pressure monitoring ( ABPM ) accurately classifies blood pressure ( BP ) status but its impact on the prevalence and control of hypertension is little known. The authors conducted a cross‐sectional study in 2012 among 1047 individuals 60 years and older from the follow‐up of a population cohort in Spain. Three casual BP measurements and 24‐hour ABPM were performed under standardized conditions. Approximately 68.8% patients were hypertensive based on casual BP (≥140/90 mm Hg or current BP medication use) and 62.1% based on 24‐hour ABPM (≥130/80 mm Hg or current BP medication use) ( P =.009). The proportion of patients with treatment‐eligible hypertension who met BP goals increased from 37.4% based on the casual BP target to 54.1% based on the 24‐hour BP target (absolute difference, 16.7%; P <.01). These results were consistent across alternative BP thresholds. Therefore, compared with casual BP , 24‐hour ABPM led to a reduction in the proportion of older patients recommended for hypertension treatment and a substantial increase in the proportion of those with hypertension control.
