Abstract/OtherAbstract:
Few studies have investigated the reproducibility of responses to antihypertensive therapies. The purpose of this study was to assess the reproducibility of the blood pressure response to a thiazide diuretic, a preferred initial treatment for hypertension. Twenty-two subjects who underwent monotherapy with hydrochlorothiazide as part of a study to identify predictors of blood pressure response agreed to undergo the same protocol a second time, 26.6+/-11.8 (range, 4-52) months after their first participation. The mean systolic and diastolic blood pressure responses to hydrochlorothiazide did not differ significantly between the first and second participation (systolic response, -14.2+/-16.4 mm Hg vs. -16.0+/-16.5 mm Hg; diastolic response, -7.1+/-11.8 mm Hg vs. -6.6+/-8.6 mm Hg), and these responses were significantly correlated between the two trials (systolic response, r=0.61 and p<0.01; diastolic response, r=0.64 and p<0.01). However, both the direction and magnitude of responses for individual subjects varied considerably, with the limits of agreement between the first and second participations (i.e., 2 standard deviations above and below the mean difference between responses) ranging from 27.4 mm Hg to -23.8 mm Hg for systolic blood pressure response and from 17.4 mm Hg to -18.4 mm Hg for diastolic blood pressure response. These results show that the average systolic and diastolic blood pressure responses to hydrochlorothiazide for a group of subjects are reproducible; however, the responses for individual subjects are unpredictable.
