About this study

A single-center, single-blind, randomized study to investigate the effectiveness of a hemodynamic-guided treatment strategy to improve blood pressure control

Read the detailed description

Hypertension is a hemodynamic-related disorder characterized by abnormalities of the cardiac output (CO) and/or systemic vascular resistance (SVR). It is hypothesized that selecting antihypertensive therapy based on patients' hemodynamic profile could lead to more effective blood pressure (BP) control than standard care in a real-world population of hypertensive patients in outpatient setting. A single-center, randomized trial was conducted to include adults with uncontrolled hypertension who seek outpatient care at Peking University People's Hospital between December 2018 and December 2019 in Beijing, China.

Participants were randomly assigned to the standard care group or the hemodynamic group in a 1:1 ratio. Impedance cardiography (ICG) was performed with all participants to measure hemodynamic parameters. Only physicians in the hemodynamic group were provided with patients' ICG findings and a computerized clinical decision support of recommended treatment choices based on patients' hemodynamic profiles. The primary outcomes were the reductions in systolic BP (SBP) and diastolic BP (DBP) levels at the follow-up visit 8(±4) weeks after baseline. Secondary outcomes included achievement of BP goal of <140/ 90 mmHg and the reductions in BP by baseline BP, age, sex, and BMI.

The ICG device used (HDproTM CHM T3002/P3005, designed by Beijing Li-Heng Medical Technologies, Ltd, manufactured by Shandong Baolihao Medical Appliances, Ltd.) was developed based on improved hardware and advanced digital filtering algorithms, and has been validated versus both invasive thermodilution and non-invasive echocardiography in different settings.

    Measured: 8 weeks post-baseline

  2. Change from baseline diastolic blood pressure at 8 weeks

    Change from baseline diastolic blood pressure at 8 weeks in the window of 4-12

    Measured: 8 weeks post-baseline

Secondary outcomes (6)
  1. BP control rate at 8 weeks

    proportion of subjects with BP < 140/90 mmHg at 8 weeks post-baseline visit

  2. Change from baseline heart rate (HR) at 8 weeks

    Change from baseline heart rate (heart beats per minute) at 8 weeks in the window of 4-12 weeks

    Measured: 8 weeks post-baseline

  3. Change from baseline cardiac index (CI) at 8 weeks

    Change from baseline cardiac index (cardiac output devided by body surface area) at 8 weeks in the window of 4-12 weeks

    Measured: 8 weeks post-baseline

  4. Change from baseline arterial stiffness (AS) at 8 weeks

    Change from baseline arterial stiffness at 8 weeks in the window of 4-12 weeks

    Measured: 8 weeks post-baseline

  5. Change from baseline systemic vascular resistance index (SVRI) at 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing ICG-guided drug selection and empirical drug selection in people with Hypertension, run by Peking University People's Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline systolic blood pressure at 8 weeks (time frame: 8 weeks post-baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04715698, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jan 2021.
