Trial summary

Hypertensive heart disease (HHD) is the leading cause of mortality and morbidity worldwide. In 2017, the prevalence of HHD worldwide was 217.9 per 100,000 people, an increase of 7.4% over 1990, which has brought huge financial burden and social and economic losses to the world.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: 45 patients with hypertensive heart disease admitted to Hong-Kong University, Shenzhen Hospital from January 1 to March 10 in 2021 were included in our study. Hypertensive heart disease was defined using the International Classification of Diseases, Ninth and Tenth Revision (ICD-10) codes. Diseases coded as I11.0 and I11.9 in ICD-10 were identified as hypertensive heart disease[1-2].

Official title: Study on the Correlation Between Serum miR-455-5p Level and Cardiac Structure and Function Parameters in Patients With Hypertensive Heart Disease

Hypertensive heart disease (HHD) is the leading cause of mortality and morbidity worldwide. In 2017, the prevalence of HHD worldwide was 217.9 per 100,000 people, an increase of 7.4% over 1990, which has brought huge financial burden and social and economic losses to the world. Therefore, HHD is a major public health challenge worldwide. In our previous studies, we found that miR-455-5p, a microRNA, could functioned as an inducer to promote cardiac hypertrophy. Because cardiac hypertrophy was a common phenomenon in patients with HHD, so it is interesting to clarify whether miR-455-5p could be employed as a marker to indicate the function and/or structure of heart in the development of HHD. Thus, the purpose of this study was to collect blood samples of hypertensive patients, as well as analysis the correlation between serum miR-455-5p level and cardiac function. The research could help doctors better predict the course of hypertensive heart disease and provide more effective treatments for different patients.

Read the detailed description

The purpose of this study was to collect blood samples of hypertensive patients, in order to clarify the correlation between serum miR-455-5p level and cardiac function. Generally, by using q-PCR assay, miR-455-5p level of each participants will be collected. Besides, SBP, DBP, LVPWd, LVIDd, IVSTd was detected by echocardiography and EF, FS, LVMi, RWT level was further calculated by LVIDd, LVPWd and IVSTd. Finally, the correlation of miR-455-5p level of HHD patients and LVPWd, LVIDd, IVSTd, EF, FS, LVMi, RWT, SBP, DBP was analysed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Measurement of serum miR-455-5p level

    concentration of microRNA-455-5p in 100ml serum was determined by Elisa assay.

    Measured: the miR-455-5p level is collected at week 0, 6, 12 and 24.

  2. Measurement of LVPWd and LVPWs

    left ventricular posterior wall thickness in diastole state and systole state are measured and recorded by echocardiography and its affiliated software.

    Measured: the LVPWd and LVPWs are collected at week 0, 6, 12 and 24.

  3. Measurement of LVIDd and LVIDs

    left ventricular internal diameter in diastole state and systole state are measured and recorded by echocardiography and its affiliated software.

    Measured: the LVIDd and LVIDs are collected at week 0, 6, 12 and 24.

  4. Measurement of IVSTd and IVSTs

    interventricular septum in diastole state and systole state are measured and recorded by echocardiography and its affiliated software.

    Measured: the IVSTd and IVSTs are collected at week 0, 6, 12 and 24.

  5. Calculation of LVMi

    left ventricular mass index was calculated based on the formula: LVMi=LVM/BSA; For LVM, LVM(g)=0.8*1.04*[(IVSTd+LVPWd+LVIDd)^3-LVIDd^3]+0.6; For BSA, BSA=[Body height (cm)*Body weight (kg)/3600]^0.5; Diagnosis of LVH: LVMi(Male)>115g/m2;LVMi(Female)>95g/m2

    Measured: the LVMi is calculated at week 0, 6, 12 and 24.

  6. Measurement of LVEF

    left ventricular ejection fraction are measured and recorded by echocardiography and its affiliated software.

    Generally, LVEF is range from 50% to 70% is regarded as normal. If LVEF less than 50%, the patient is suspected to suffered cardiac systolic dysfunction.

    Measured: the EF is calculated at week 0, 6, 12 and 24.

  7. Measurement of FS

    Fractional shortening are measured and recorded by echocardiography and its affiliated software.

    Generally, FS is range from 25% to 45% is regarded as normal. If FS less than 25%, the patient is suspected to suffered cardiac systolic dysfunction.

    Measured: the FS is calculated at week 0, 6, 12 and 24.

  8. SBP

    systolic blood pressure was measured by sphygmomanometer. For patients whose SBP is higher than 140mmHg, the patients is regarded as hypertension.

    Measured: the SBP is collected at week 0, 6, 12 and 24.

  9. DBP

    diastolic blood pressure was measured by sphygmomanometer. For patients whose DBP is higher than 90mmHg, the patients is regarded as hypertension.

    Measured: the DBP is collected at week 0, 6, 12 and 24.

Questions about this trial

What is this clinical trial studying?

An observational study of Hypertension and Heart Disease, run by The University of Hong Kong-Shenzhen Hospital at 1 site in China.

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 1 inclusion and 1 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: enrolling by invitation, as of the sponsor's last update on 24 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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 the primary outcome measure?

Measurement of serum miR-455-5p level (time frame: the miR-455-5p level is collected at week 0, 6, 12 and 24.). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.
