- W4315703330 abstract "Background: Hypertension is the most prevalent chronic disease worldwide and is related to a high probability of cardiac disease, kidney disease and cerebrovascular events. Blood pressure measurement was used in the last decades to diagnose and guide antihypertensive therapy; however blood pressure is the result of the interaction of more complex hemodynamic parameters previously reserved for experimental studies or critical care patients management using invasive methods. Since 1996 few studies have proposed the use of hemodynamic parameters to classify and guide hypertension therapy with good results. Purpose: The present study's purpose was to measure hemodynamic parameters in patients with non-controlled resistant hypertension and use it to guide pharmacologic treatment to archive control blood pressure values according to the European Society of Cardiology guidelines. Methods: A total of 84 patients between 32 and 95 years old diagnosed with non-controlled primary resistant hypertension were recruited and after previous therapy washout hemodynamic parameters were measured using noninvasive Methods: preload by central venous pressure (CVP) using inferior vena cava diameter, cardiac index and systemic vascular resistance using Lyljestrand & Zander modified formula. Patients were classified into 3 basic groups depending on which parameter was above normal value: hyperdynamic (HD) for high cardiac index > 3.5 L/min/m2, fluid overload (FO) for CVP > 8cmH2O and high systemic vascular resistance index (HSVRi) > 2500 dynes/sec/m2/cm5, also 3 combined groups were a patient had 2 simultaneous hemodynamic alterations (HD+FO, HD+HSVRi and FO+HSRVi), according to this classification pharmacotherapy was guided indicating Bisoprolol in HD group, Amlodipine to HSVR patients and Hydrochlorothiazide to FO patients, in combined groups, combined therapy was given. Patients were observed for 6 months period taking as primary endpoint blood pressure control, acute cardiovascular events and hypotension. Results: A significant reduction of hemodynamic parameters and blood pressure was observed in the first month of treatment obtaining a 100% hemodynamic and blood pressure goals in all patients in the third month of therapy without hypotension or acute cardiovascular event during this period, the HD+FO group reach goals at the 6th month of treatment without reported complications. Conclusions: In this preliminary study we observed that hemodynamic guided high blood pressure control may be a valuable tool for a better understanding, classification and treatment in patients with resistant hypertension; however larger outcome studies confirm this hypothesis." @default.
