Abstract
The optimal target blood pressure (BP) in the treatment of hypertensive patients remains
controversial. Recently, the systolic blood pressure trial (SPRINT) has proposed that
a target systolic blood pressure of < 120 mmHg provides prognostic benefit in elderly
hypertensive patients at high cardiovascular risk. The results of SPRINT contrast
with several other intervention trials which have investigated the effect of intense
BP lowering (Secondary Prevention of Small Subcortical Strokes [SPS3], Action to Control
Cardiovascular Risk in Diabetes [ACCORD], Heart Outcomes Prevention Evaluation [HOPE]-3).
The differences in outcomes in SPRINT vs. other intervention trials are, to a large
extend, due to an "unobserved" BP measurement procedure utilized in the SPRINT trial.
Thus, a BP goal of < 120 mmHg, at least by conventional BP measurement, remains unproven.
Independent of SPRINT the controversial evidence with respect to BP targets calls
for further studies and, possibly, for more individualized treatment goals.
Arterielle Hypertonie gilt als wichtigster kardiovaskulärer Risikofaktor. Im folgenden
Beitrag wird die Frage des optimalen Zielblutdrucks näher beleuchtet und aufgezeigt,
wie Alter, Ausgangsblutdruck sowie verschiedene Blutdruckmessverfahren Einfluss auf
eine wirksame Therapie nehmen können. Außerdem wird erläutert, ob eine zu starke Blutdrucksenkung
das Risiko kardiovaskulärer Komplikationen sogar erhöhen kann.
