Background: Hypertension is an important risk factor for
cardiovascular events, stroke and kidney disease, optimal
hypertension control still a controversial subject in medical
literature, several studies proposed the hypertension
control calculating hemodynamic parameters.
Materials and Methods: In the present study we recruited
84 patients’ males (34%) and females (49%) between 32
and 95 years of age with non-controlled hypertension
taken 2 or more medications and measured heart rate (HR),
systolic (SBP), diastolic (DBP) and mean (MAP) blood
pressure, pulse pressure (PP), cardiac index (CI) using
Liljestrand & Zander modified formula to calculate stroke
volume (CI=[HR*(PP/MAP)] / Body surface area), central
venous pressure (CVP) using inferior vena cava diameter
(IVCD), systemic vascular resistance index

Conclusion: Hemodynamic guided treatment to
control high blood pressure had good results in this
study; however, bigger trials are needed to prove his
efficacy.
(SVRi=MAP/CI*80) and divided in six hemodynamic groups:
Hyperdynamics (Hd) were those with CI>3,5L/min/m2, High
Resistance (Hr) group when SVRi>2500dynas, Fluid
overload (FO) whenCVP>8cmH2O or IVCD>2cm and mixed
types, Hd+Hr, Hd+FO and Hr+FO, a basal values was
measured after 1 week washout with captopril, after
washout treatment was selected according hemodynamic
groups with a 6 months follow up.
Results: We found a statistical significant reduction of all
parameters at the first month after treatment and
hypertension control according European of Society
Cardiology guidelines in 100% of patients at 3th month of
treatment with hemodynamic normalization, only Hd+FO
at 6th month, with no symptomatic hypotension.
