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 80 years and older
  • All sexes
  • No healthy volunteers
  • Older adult

Who may be able to join

  • Aged 80 or older
  • Sitting systolic BP 160-199 mmHg AND sitting diastolic BP < 110 mmHg

Who cannot join

  • Known accelerated hypertension (retinal haemorrhages or exudates or papilloedema).
  • Overt clinical congestive heart failure requiring treatment with a diuretic or angiotensin converting enzyme inhibitor. Subjects allowed if treated with digoxin only.
  • Renal failure (serum creatinine of more than 150 µmol/l).
  • Previous documented cerebral or subarachnoid haemorrhage in the last 6 months. (Ischaemic cerebral and cardiac events do not exclude, although the patient must be neurologically and cardiologically stable.)
  • Condition expected to severely limit survival, e.g. terminal illness.

  • Gout.
  • Clinical diagnosis of dementia.
  • Resident in a nursing home, i.e. where the dependency and care requirements of the patients are such that they require the regular input of qualified nurses and therefore the majority of staff in the home are nurses (other forms of residential care are acceptable).

About this study

The purpose of this study is to assess the benefits and risks of treating very elderly (those aged 80 or older) individuals with hypertension.

Read the detailed description

The benefit to risk ratio of treating hypertensives aged 80 or older has not been established. It has been suggested that at this age for each stroke prevented there is one non-stroke death. HYVET is designed to help clarify this.

HYVET is a randomised, double-blind, placebo-controlled trial in hypertensive subjects aged 80 or older. Active treatment consists of indapamide 1.5mg SR with the addition of perindopril 2mg - 4mg to reach a target blood pressure (BP) of <150/80 mmHg. Entry criteria include a systolic blood pressure of 160-199 mmHg. Patients with isolated systolic hypertension (ISH) have been recruited since August 2003.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Indapamide SR 1.5mg; Perindopril 2-4mg in people with Hypertension, run by Imperial College London at 7 sites in 6 countries.

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 2 inclusion and 14 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 21 Aug 2007. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in Bulgaria, China, Finland, Romania, Russia and 1 more country. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

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?

All strokes (fatal and non-fatal) (time frame: Duration of trial). 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 NCT00122811, which also lists 16 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 21 Aug 2007.
