Study summary

Patients with cardiovascular diseases from Guangdong province will be recruited and followed up for at least 4 years to evaluate the risk factors for cardiovascular-related mortality and disability. Physical examination, questionnaire survey and biological sample collection will be conducted at baseline and the incidence of all-cause and cardiovascular mortality will be investigated during follow-up.

Read the detailed description

5,000 patients (30-85 years old) with primary hypertension, coronary heart disease, heart failure or peripheral vascular disease and who have been living in Guangdong province for more than 5 years will be recruited. All participants will be prospectively followed up for the incidence of all-cause and cardiovascular mortality. Information about socio-demographic, diet, lifestyle, psychological status, medical history and current medication will be collected by questionnaires. Physical examinations including height, weight, waist and hip circumferences, blood pressure, fat mass and vital capacity will be conducted.Besides, blood, urine and fecal samples will be collected for further analysis. The associations between diet and lifestyle and risks for cardiovascular disease will be evaluated.

What researchers measure

Primary outcomes

  1. All-Cause Mortality

    All-cause mortality was confrmed through a combination of hospital medical records, telephone contacts with patients or family members, and death registration at the Guangdong Provincial Center for Disease Control and Prevention.

    Time frame: 4 years

Secondary outcomes

  1. Cardiovascular Mortality

    Cardiovascular mortality was defned as death attributable to an ischemic cardiovascular cause (including fatal MI, stroke, and peripheral arterial disease) or sudden death due to an unknown but presumed cardiovascular cause in high-risk patients.

    Time frame: 4 years

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Nov 2017 (actual). Primary completion is estimated for Dec 2030, 157 months after the start.

Of 580 non-industry observational studies under Cardiovascular Diseases, half reached primary completion within 70 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 196. This study's planned 157 months is above that.

Counting every sponsor, half of 664 studies reached it within 61 months; a quarter within 24 and three quarters within 192.

Cardiovascular Diseases covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 5, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
