Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

17 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patient treated with ACE or candesartan in the period 1999 - 2007.

Description

Inclusion Criteria:

  • all patients found in electronic patient journals at the participating centres, who were prescribed either ACEis (ATC-C09A-B) or ARBs (C09C-D) for hypertension from 1 January 1999 - 31 December 2007. The first date of such a prescription starts the observation time and is called the index prescription.

Exclusion Criteria:

  • No history of cardiovascular disease.
  • Ongoing malignancy

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Investigate the risk of Cardiovascular Disease (CVD) and new onset diabetes in patients on primary hypertensive treatment with ACE or candesartan for hypertension
Time Frame: Time to first CV event calculated as the time (in days) between date of index prescription and date of the first registration of a CV event. Patients will be followed for min. 1 wk and up to 9 yrs (1999-2007). Median follow up time is estimated to 2 yrs.
Time to first CV event calculated as the time (in days) between date of index prescription and date of the first registration of a CV event. Patients will be followed for min. 1 wk and up to 9 yrs (1999-2007). Median follow up time is estimated to 2 yrs.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
To investigate the risk of CVD and new onset diabetes in patients treated with specific types of ACEi or candesartan for hypertension
Time Frame: Time to first CV event calculated as the time (in days) between date of index prescription and date of the first registration of a CV event. Patients will be followed for min. 1 wk and up to 9 yrs (1999-2007). Median follow up time is estimated to 2 yrs.
Time to first CV event calculated as the time (in days) between date of index prescription and date of the first registration of a CV event. Patients will be followed for min. 1 wk and up to 9 yrs (1999-2007). Median follow up time is estimated to 2 yrs.
To investigate the risk of hypertensive organ damage, renal failure and hyperlipidemia for patients treated with ACEi or candesartan
Time Frame: Time to first CV event calculated as the time (in days) between date of index prescription and date of the first registration of a CV event. Patients will be followed for min. 1 wk and up to 9 yrs (1999-2007). Median follow up time is estimated to 2 yrs.
Time to first CV event calculated as the time (in days) between date of index prescription and date of the first registration of a CV event. Patients will be followed for min. 1 wk and up to 9 yrs (1999-2007). Median follow up time is estimated to 2 yrs.
Evaluate differences in use of health care resources, and assess the potential long term cost effectiveness
Time Frame: Differences in health care consumption will be estimated through models incorporating normalised costs, level of care, age, gender and study year
Differences in health care consumption will be estimated through models incorporating normalised costs, level of care, age, gender and study year

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2010

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
