About this study

This study is a registry study to examine the clinical features, blood pressure control rate, and clinical prognosis of resistant hypertension in Koreans. This study will register patients with resistance hypertension in eight tertiary hospitals in Korea and follow up them for three years. The prognosis will be analysed according to etiologies, achieved blood pressure, and types of antihypertensive medication.

Read the detailed description

This study will enroll hypertensive patients who are in treatment or those who are referred from primary clinic based on inclusion or exclusion criteria. Basic clinical information, compliance with antihypertensive medications, concomitant use of other medications will be investigated and all patients will perform 24-hr ambulatory blood pressure measurement. Screening for renal artery stenosis and primary aldosteronism will be conducted. Office blood pressure will be taken every 3-6 months. Home blood pressure measurement and 24-hr ambulatory blood pressure measurement will be performed every year. The primary outcome is the newly developed MACE during the follow-up period. The secondary outcomes are newly developed target organ damage (LVH confirmed by echocardiography or EKG, carotid femoral PWV≥ 12m/s, microalbuminuria (Urine albumin-creatinine ratio ≥30 mg/g)) and decline of renal function (doubling of serum creatinine, dialysis). The follow-up period is 3 years.

What is being measured

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

  1. Major adverse cardiac events

    Composite of cardiovascular death, myocardial infarction, stroke, admission for heart fails

    Measured: 3 years

Secondary outcomes (3)
  1. Progression of CKD

    Start dialysis or doubling of serum creatinine

    Measured: 3 years

  2. Target organ damages

    Target organ damage: LVH confirmed by echocardiography or EKG; carotid femoral PWV≥ 12m/s; microalbuminuria (Urine albumin-creatinine ratio ≥30 mg/g)

    Measured: 3 years

  3. Target blood pressure achievement

    Target blood pressure: Achievement of BP below 130/80 or 140/90 mmHg

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Resistant Hypertension, run by Yonsei University at 1 site in South Korea.

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 3 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 30 May 2018. 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 South Korea. 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?

Results are not available in the source record.

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

Contact Sungha Park, MD (82-2-2228-8455, shpark0530@yuhs.ac), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Major adverse cardiac events (time frame: 3 years). 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 NCT03540992, which also lists 2 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 30 May 2018.
