Management in a hypertension clinic achieved satisfactory clinic blood pressure control in 50.3% of 700 patients, though ambulatory monitoring in a subgroup suggested this overestimates true control.

Clinic blood pressure measurements may overestimate true blood pressure control compared to ambulatory monitoring, which correlates better with target organ damage such as left ventricular hypertrophy.
OBJECTIVES: First, to evaluate the prevalence of clinic blood pressure (BP) control (BP 125 g/m2 in men and >110 g/m2 in women). DESIGN AND METHODS: Seven hundred consecutive hypertensive patients who attended our hypertension centre clinic during a period of 6 months and who had regularly been followed up by the same medical team were included in the study. BP was taken in the clinic by a doctor using a mercury sphygmomanometer with the participants seated. Seventy-four patients with similar demographic and clinical characteristics to the entire population of participants underwent complete echocardiographic examination and 24 h ABP monitoring. RESULTS: During follow-up, 352 of the treated patients had clinic BP 160/95 mm Hg, indicating that BP control was satisfactory in 50.3%, borderline in 28.3% and unsatisfactory in 21.4% of the cases. In the subgroup of 74 patients, the proportion of individuals with satisfactory clinic BP control (CBP< or =140/90 mm Hg) was higher (50.0 versus 33.6%) than with satisfactory ABP control (daytime ABP values < or =132/85 mm Hg). LVH was found in 21 of the 74 patients (28.3%): 12 of them had unsatisfactory CBP control and 19 had unsatisfactory ABP control. LVMI did not correlate with CBP values but only with ABP values (mean 24 h systolic r = 0.47, diastolic r = 0.40, P<0.001; mean daytime systolic r = 0.45, mean daytime diastolic r = 0.39, P<0.001; mean night-time systolic r = 0.38, mean night-time diastolic r = 0.38, P<0.001). CONCLUSION: This study demonstrates that hypertensive patients managed in a hypertension centre clinic have satisfactory CBP control in 50% of cases, but this rate seems to over-estimate the effective BP control during daily life. A large fraction of patients show persistence of LVH and this evidence of organ damage almost entirely concerns individuals with poor ABP control.
Cuspidi et al. (Tue,) conducted a observational in Hypertension (n=700). Management in a hypertension centre clinic was evaluated on Prevalence of clinic blood pressure control (<= 140/90 mm Hg). Management in a hypertension clinic achieved satisfactory clinic blood pressure control in 50.3% of 700 patients, though ambulatory monitoring in a subgroup suggested this overestimates true control.
