Central Hemodynamic and Sodium Urinary (CHASSI)
Analysis of Central Hemodynamic Parameters and Sodium Urinary Excretion in Controlled and Resistant Hypertensive Patients
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
The urinary sodium (Na+) will be evaluated by flame photometry. Excretion of urinary sodium will be calculated by multiplying the urinary sodium concentration in mE /L by 24-hour urinary volume. Two to three urinary Na+ samples will be collected within six months.
3.3.3 ABLOOD PRESSURE MONITORING - 24 HOURS Ambulatorial blood pressure monitoring 24-hour will be performed using a Mobil-O-Graph® compact digital device (version 12, ambulatory pressure monitor, 2000, UK). Individuals will be instructed to maintain their normal activities of daily living. The device will be pre-programmed to measure blood pressure within 24 hours at 30-minute intervals every hour during the waking period and at 1-hour intervals during sleep. This device will evaluate the following parameters: systolic and peripheral diastolic blood pressure, mean arterial pressure, pulse pressure, systolic central aortic pressure, central diastolic aortic pressure (cDBP), central pulse pressure (cPP), augmentation index corrected for 75 bpm (AI75%) and pulse wave velocity (PWV).

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Controlled Hypertensive Patients (CHP)
Hypertensive patients that have blood pressure less than 140 x 90 mmHg.
This parameter must be evaluated by ambulatory blood pressure monitoring
|
|
Resistant Hypertensive Patients (RHP)
Hypertensive patients that have blood pressure more than 140 x 90 mmHg and they use three antihypertensive medicines; or hypertensive patients that have blood pressure less than 140 x 90 mmHg, but they use four or more antihypertensive medicines.
This parameter must be evaluated by ambulatory blood pressure monitoring.
|
Evaluation of the individuals has the objective determine if they are resistant hypertensive patients.
This is important because the resistant people have worse prognosis than the controlled people and need more attention from the health professionals.
Analysis must be done using the ambulatory blood pressure monitoring.

Measure Description |
Time Frame |
---|---|---|
Pulse wave velocity
Time Frame: The urinary sodium excretion will be evaluated during 24 hours. This evaluation will be done by 2 to 3 times in a period of 6 months. Pulse wave velocity will be also evaluated in this period by the ambulatory blood pressure monitoring 24 hours.
|
The investigators has the objective of investigating if the urinary sodium quantity is associated with pulse wave velocity in resistant hypertensive individuals.
|
The urinary sodium excretion will be evaluated during 24 hours. This evaluation will be done by 2 to 3 times in a period of 6 months. Pulse wave velocity will be also evaluated in this period by the ambulatory blood pressure monitoring 24 hours.
