Reference values for clinic pulse pressure in a nonselected population.

A wide pulse pressure (PP) may constitute an independent predictor of cardiovascular morbidity and mortality. We assessed the reference values of brachial clinic PP, according to age and gender in a nonselected population (61,724 subjects) who were undergoing a routine systematic health examination. According to mean values, 50 mm Hg is likely the reference value for clinic PP in both men and women. Diagnostic thresholds for clinic PP (> or =65 mm Hg) determined either by adding 2 SD to the means or from the 95th percentiles are in close agreement with clinic PP values previously reported to be associated with increased cardiovascular morbidity and mortality.
