Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Sampling Design: hypertensive patients will be continuously sampled for case detection in each center. PASS 11.0 Software-Confidence Intervals for One Proportion was used to calculate the sample size. A sample size of 2928 produces a two-sided 95% confidence interval with a width equal to 0.02 when the sample proportion(prevalence of PA) is 0.080. Accounting for the 20% withdraw rate in the process of case detection, the final sample size should be 3635 (about 4000 cases).

Who may be able to join

  • Newly diagnosed hypertension(with a course less than six months);
  • Drug negative, or voluntary to discontinue/change the anti-hypertensive medications;
  • Aged between 18-80 year, gender is not limited;
  • Voluntary to sign on the informed consent.

Who cannot join

  • patients with severe cardiac, hepatic or renal dysfunction;
  • suspicious or confirmed other types of secondary hypertension, including Cushing's syndrome, pheochromocytoma and renal artery stenosis.

About this study

To investigate the prevalence of primary aldosteronism (PA) in Chinese patients with newly diagnosed hypertension.

Read the detailed description

This is a nationwide sampling study. To investigate the prevalence of primary aldosteronism (PA) in Chinese patients with hypertension, we will conduct a case detection of PA in Chinese hypertensive patients from 10 centers of China (including Beijing, Chongqing, Shanghai, Guangzhou, et al.); furthermore, a case confirmation of PA (captopril challenge test and saline infusion test) will be performed if the result of case detection is positive. This study will be completed in two years.

Being tested
Aldosterone/renin ratio (ARR) testing, Confirmatory tests
Keywords

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of subjects with newly diagnosed hypertension

    To calculate the prevalence of PA in Chinese patients with hypertension

    Measured: 2 years

  2. Number of subjects with confirmed primary aldosteronism (PA)

    To calculate the prevalence of PA in Chinese patients with hypertension

    Measured: 2 years

  3. Prevalence of PA

    Prevalence of PA= Number of PA / Number of subjects with hypertension

    Measured: 2 years

Secondary outcomes (5)
  1. Age

    Characteristics of PA in Chinese patients with hypertension

    Measured: 2 years

  2. Blood pressure

    Characteristics of PA in Chinese patients with hypertension

    Measured: 2 years

  3. Family history of hypertension

    Characteristics of PA in Chinese patients with hypertension

    Measured: 2 years

  4. Fasting blood glucose

    Characteristics of PA in Chinese patients with hypertension

    Measured: 2 years

  5. Cardiovascular events

    Characteristics of PA in Chinese patients with hypertension

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Hyperaldosteronism; Primary and Hypertension Secondary, run by Qifu Li 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 2 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 23 Oct 2020. 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?

Number of subjects with newly diagnosed hypertension (time frame: 2 years). The study lists 3 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 NCT03155139, which also lists 4 linked publications.

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 23 Oct 2020.
