Background: Bos et al stated that the well known one-third rule for the calculation of mean arterial pressure (MAP) from diastolic (DBP) and pulse pressure (PP) underestimates the MAP. We calculated the percentage (form factor, FF) of the PP to be added to the DBP to assess MAP at the brachial artery in a population sample of young adults and compared middle-aged adults.
Methods: Brachial artery tonometer measurements were performed in 95 healthy subjects (18 men, 77 women; age 19–35 yr). The pressure waveforms were calibrated using sphygmomanometer SBP and DBP. MAP was assessed as the numerical average of this pressure wave curve.
Results: The table shows the FF as mean percentage ± SD. The FF at the brachial artery was 2.1±0.9 % higher in women compared to men (p<0.02).
| FF % (SD) | Men | Women | Total |
|---|---|---|---|
| Age 19–35 yrs | 37.2 (3.1) | 39.2 (3.4) | 38.9 (3.4) |
| FF based on published data from the Asklepios study (age 35–55) * | |||
| Age 35–55 yrs | 41.3 (3.0) | 43.7 (3.1) | 42.4 (3.3) |

Conclusions: The present study confirms the findings from the Asklepios Study that the form FF to calculate MAP is higher in women than in men. This study also suggests that the FF is age dependent being lower in the age range of 19–35 compared to the range 35–55. Further research is needed to define the influence of age on the form factor to calculate MAP.
