[Care of hypertensive patients seen by cardiologists: results of the Snapshot Hypertension Registry].

BACKGROUND: The objective of the Snapshot Hypertension Registry (SHR) was to assess the quality of antihypertensive drug treatment in hypertensive patients seen by cardiologists on three consecutive days in December 2005.
METHODS: Full data sets were obtained for 7302 patients (89.9% of total returned) seen by 268 cardiologists. Mean age of hypertensive patients was 65.4 +/- 11.2 years, 62 % were male, and 93 % were referred to the cardiologist by a general practitioner.
RESULTS: Judging from their casual ("snapshot") blood pressure, 35.3 % were well treated (< 140/90 mm Hg). According to the 24-hour ambulatory blood pressure even a lower rate of hypertensive patients, namely 27.6 %, had their blood pressure well controlled (< 130/80 mm Hg). Of all patients, 24 % were on monotherapy. Only 33.7 % of the patients on monotherapy were normotensive. Of all patients on a combination of drugs 36.9 % were normotensive according to the casual blood pressure measurements. Private patients were prescribed angiotensin receptor blockers more frequently than patients who only had statutory health insurance.
CONCLUSIONS: The Snapshot Registry analysis revealed that the casual blood pressure in the majority of hypertensive patients who were reviewing antihypertensive medication was not in the normotensive range. In addition, our data demonstrate that evidence-based antihypertensive medication was often not adequately used in Germany.
