Chinese Multi-provincial Cohort Study-Beijing Project (CMCS-Beijing)

December 2, 2020 updated by: Beijing Institute of Heart, Lung and Blood Vessel Diseases
The Chinese Multi-provincial Cohort Study (CMCS)-Beijing project is a sub-study in CMCS participants from Beijing, which intended to investigate the progression and determinants of atherosclerosis and aging related health problems through repeat examinations. Exam 0 to Exam 3 have been conducted during 1992 to 2012. Exam 4 is scheduled in 2020.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

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
Measure Description
Time Frame
All fatal and nonfatal acute coronary and stroke events
Time Frame: From date of enrollment until the date of first documented event or date of cardiovascular death, whichever came first, assessed at least 5 years
Acute coronary heart disease events included acute myocardial infarction, sudden death, and other coronary deaths. Acute stroke events included subarachnoid hemorrhage, intracerebral hemorrhage, or cerebral infarction.
From date of enrollment until the date of first documented event or date of cardiovascular death, whichever came first, assessed at least 5 years

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
Measure Description
Time Frame
New-onset of coronary events
Time Frame: From date of enrollment until the date of first documented event or date of CHD death, whichever came first, assessed at least 5 years
Acute coronary heart disease events included acute myocardial infarction, sudden death, and other coronary deaths.
From date of enrollment until the date of first documented event or date of CHD death, whichever came first, assessed at least 5 years
New-onset of stroke
Time Frame: From date of enrollment until the date of first documented event or date of stroke death, whichever came first, assessed at least 5 years
Acute stroke events included subarachnoid hemorrhage, intracerebral hemorrhage, or cerebral infarction.
From date of enrollment until the date of first documented event or date of stroke death, whichever came first, assessed at least 5 years
Total death
Time Frame: From date of enrollment until date of death from all cause, assessed at least 5 years
All cause death
From date of enrollment until date of death from all cause, assessed at least 5 years

Time Frame: From date of enrollment until the date of first documented event or date of valvular disease death, whichever came first, assessed at least 5 years
Valvular disease
From date of enrollment until the date of first documented event or date of valvular disease death, whichever came first, assessed at least 5 years

Study Major Dates

Study Start (ACTUAL)

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.

Primary Completion (ANTICIPATED)

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.
