Over the last thirty years white coat hypertension has been the object of numerous studies which suggest that the interactions between doctor and patient and environmental, psychological circumstances suffice to determine a significant increase of arterial pressure in subjects who are generally normotense. The aim of this study was to evaluate the prevalence of white coat hypertension in elderly subjects with hypertension which had been diagnosed recently using the traditional sphygmomanometric method three times in the space of one week. We divided 69 patients (age range 60 to 82 years) into three groups depending on their clinic pressures, i.e. patients with isolated systolic, systo-diastolic or diastolic hypertension. Non invasive 24 h pressure ambulatory monitoring was performed in each subject using a Takeda recorder TM 2420 and adopting a protocol for single measurements at 15 minutes intervals between 08.00 and 20.00 (daytime measurements) and 30 minutes intervals between 20.00 and 08.00 (night-time measurements). Ambulatory monitoring with less than 60 recordings, and those where measurements were not taken for over 60 minutes during the day or 90 minutes during the night were excluded from the study, and the mean daytime and 24 h pressure load was calculated. Monitoring conducted in 60 subjects (39 males and 21 females) was considered valid. Statistical analysis of the mean arterial pressure values of each subject determined by the two methods was performed using a t-test. Comparison between mean clinic, daytime and 24 h ambulatory pressure in the whole study population showed a statistically significant decrease (P <0.001) in mean daytime systolic ambulatory pressure and mean 24 h systolic and diastolic ambulatory pressure compared with mean clinical values, whereas mean daytime diastolic ambulatory levels presented a slightly lower, albeit statistically significant reduction (P <0.5). Our data showed that overall prevalence of white coat hypertension is 31.67%. Moreover, they agree with the literature that this prevalence is significant (73.67%) in subjects with isolated systolic hypertension.
