Blood pressure control and physician management of hypertension in hospital hypertension units in Spain

Abstract

Goal blood pressure (BP) was defined by the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-VI) and the World Health Organization-International Society of Hypertension (WHO/ISH) as <140 mm Hg systolic and <90 mm Hg diastolic for the general and <130 mm Hg systolic and <85 mm Hg diastolic for special high-risk populations. However, there are few reports that address BP control among special subgroups of hypertensives by reference to targeted BP. We therefore conducted a study to evaluate BP control of 4049 hypertensives in 47 hospital-based hypertension units in Spain. Overall, 42% of patients achieved goal BP (<140 mm Hg systolic and <90 mm Hg diastolic). Only 13% of diabetic patients and 17% of those with renal disease achieved the BP goal (<130 mm Hg systolic and <85 mm Hg diastolic), and only 10% and 12%, respectively, achieved the even more rigorous goal (<130 mm Hg systolic and <80 mm Hg diastolic). Likewise, only 18% of patients in JNC-VI risk group C and 17% of WHO/ISH high-risk patients attained a goal BP <130 mm Hg systolic and <85 mm Hg diastolic. BP control (<125 mm Hg systolic and <75 mm Hg diastolic) was extremely low (2%) in patients with proteinuria >1 g/d. Poorer BP control was observed among patients at high risk, with diabetes, renal disease, or obesity, than in lower-risk groups. BP control was lower for systolic than for diastolic BP. In >50% of uncontrolled patients, no measures were taken by doctors to optimize pharmacologic treatment, and approximately one-third of patients were still using drug monotherapy. Control of BP, particularly of systolic BP, is still far from optimal in hospital-based hypertension units. Patients at high risk, with diabetes or proteinuria, warrant focused attention. Moreover, a more aggressive behavior of doctors treating uncontrolled hypertension is needed.
