About this study

Official title: Relationship Between Arteriosclerosis and Myocardial Work in Hypertensive Patients With Left Ventricular Ejection Fraction Retention

Hypertension is a serious threat to human health and a major global economic burden.Chronic hypertension can cause left ventricular remodeling and loss of function, eventually leading to heart failure.Exploring the early changes and mechanisms of left ventricular cardiac function caused by hypertension, and to identify individuals who may develop into serious heart injury, may play a positive role in the early prevention and control of heart failure caused by hypertension.Therefore, this study intend to use two-dimensional speckle tracking technology, a non-invasive method to measure left ventricular pressure-strain loop to quantitatively reflect cardiac work index , to study different hypertension patients with normal left ventricular ejection fraction the change of the global and local cardiac work, and the influence of aterosclerosis in thes patients to myocardial work, and explore their relationship with ventricular remodeling and abnormal diastolic function.To improve the understanding of the pathophysiology of hypertension, hypertensive heart disease and heart failure, and to provide scientific support for the early prevention and control of such diseases.

Read the detailed description

Hypertension is a serious threat to human health and a major global economic burden.Chronic hypertension can cause left ventricular remodeling and loss of function, eventually leading to heart failure. Ventricular remodeling in hypertensive patients is an adaptive and decompensating response to persistent elevated blood pressure and increased myocardial work load. Exploring the early changes and mechanisms of left ventricular cardiac function caused by hypertension, and to identify individuals who may develop into serious heart injury, may play a positive role in the early prevention and control of heart failure caused by hypertension.Therefore, this study intend to use two-dimensional speckle tracking technology, a non-invasive method to measure left ventricular pressure-strain loop to quantitatively reflect cardiac work index , to study different hypertension patients with normal left ventricular ejection fraction (including hypertension without heart damage performance with different degree of high blood pressure, hypertension with diastolic dysfunction , hypertension with left ventricular hypertrophy ) the change of the global and local cardiac work, and the influence of aterosclerosis in thes patients to myocardial work, and explore their relationship with ventricular remodeling and abnormal diastolic function.To improve the understanding of the pathophysiology of hypertension, hypertensive heart disease and heart failure, and to provide scientific support for the early prevention and control of such diseases.

Questions about this trial

What is this clinical trial studying?

An observational study of Hypertension; Heart Disease, Hypertensive, run by Chongqing Medical University 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 4 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 5 Oct 2020. 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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact QIN DUAN (8618623349865, 570549500@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

myocardial work (time frame: 2020.09-2021.01). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04573257, which also lists 1 linked publication.

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 5 Oct 2020.
