About this study
The primary objective was to assess whether long-term administration of antihypertensive therapy to elderly subjects with isolated systolic hypertension reduced the combined incidence of fatal and non-fatal stroke. The secondary objectives were to evaluate: the effect of long-term antihypertensive therapy on mortality from any cause in elderly people with isolated systolic hypertension; possible adverse effects of chronic use of antihypertensive drug treatment in this population; the effect of therapy on indices of quality-of-life; the natural history of isolated systolic hypertension in the placebo population.
Read the detailed description
BACKGROUND:
More than 3 million persons in the United States over the age of 60 have isolated systolic hypertension. They face an excess risk (2-3 fold) of stroke, other cardiovascular disease and death. Population-based data show that the prevalence rises from approximately 8 percent in the age group 60-69 years to approximately 20 percent over the age of 80. Based on available data, an annual stroke rate of 2.0 percent has been estimated in this population. The full-scale clinical trial followed a pilot study conducted from 1980 to 1983. Recruitment in the trial began in March 1985 and was finished in January 1988. Follow-up ended in February 1991. Data analysis continued through October 1996.
DESIGN NARRATIVE:
A randomized, double-blind trial in which 2,365 subjects were assigned to active treatment and 2,371 to placebo. For the active treatment group, a stepped-care regimen was used which included chlorthalidone 12.5 or 25 mg/day, and as needed, addition of atenolol 25 or 50 mg/day or reserpine, 0.05 or 0.10 mg/day. Treatment goal was to reduce systolic blood pressure by at least 20 mm Hg from baseline and to below 160 mm Hg with minimal amounts of study medication. The primary endpoint was the incidence of fatal and non-fatal stroke. Secondary endpoints were cardiovascular and coronary morbidity and mortality, all-cause mortality, and quality-of-life measures.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The primary objective was to assess whether long-term administration of antihypertensive therapy to elderly subjects with isolated systolic hypertension reduced the combined incidence of fatal and non-fatal stroke. The secondary objectives were to evaluate: the effect of long-term antihypertensive therapy on mortality from any cause in elderly people with isolated systolic hypertension; possible adverse effects of chronic use of antihypertensive drug treatment in this population; the effect of therapy on indices of quality-of-life; the natural history of isolated systolic hypertension in the placebo population.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing chlorthalidone, atenolol and reserpine in people with Cardiovascular Diseases and Cerebrovascular Disorders, run by National Heart, Lung, and Blood Institute (NHLBI).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 15 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.
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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00000514, which also lists 49 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 15 Apr 2016.
