Trial summary

There have been reports suggesting that progressive RV failure and death in connective tissue disease (CTD) are related to right ventricular hypertrophy (RVH) and dilation, irrespective of pulmonary arterial hypertension (PAH). Read more about this study

About this study

Official title: Early Detection of Cardiac Impairment and Prediction of Right Ventricular Hypertrophy in Patients With Connective Tissue Disease

There have been reports suggesting that progressive RV failure and death in connective tissue disease (CTD) are related to right ventricular hypertrophy (RVH) and dilation, irrespective of pulmonary arterial hypertension (PAH). The investigators aim to identify cardiac markers that occur before RVH and to investigate predictors of RVH.

Read the detailed description

Patients with connective tissue disease (CTD) frequently exhibit multi-organ pathophysiological and functional damage. The heart, one of the leading causes of CTD mortality, has attracted increasing attention. However, most patients with CTD present with nonspecific cardiac symptoms, normal ECG, and preserved left ventricular ejection fraction (LVEF) and therefore do not receive an early cardiac diagnosis. Pulmonary arterial hypertension (PAH), right ventricular (RV) dilatation and hypertrophy are the first and the most frequent cardiac findings. However, these are late-stage phenomena, which can eventually lead to death or right heart failure in CTD.Right ventricle abnormalities is associated with the risk of heart failure and cardiovascular death. RV dilation has long been considered a direct consequence of pulmonary arterial hypertension (PAH), but recently, physicians have observed RVH in CTD patients as well. RV dilation and RVH are not necessarily found in the same patient. The pathophysiology behind these issues is less well-understood. RVH progression continues even as CTD-associated PAH alleviates. This finding implies PAH might not be the sole index that leads to RVH. It would be interesting to explore factors that can predict the presence of RVH, which may reduce major adversecardiovascular events in patients with CTD.

Cardiovascular magnetic resonance (CMR) is able to depict myocardial characteristics from structure to tissue properties using cine and late gadolinium enhancement (LGE) sequences. Newly developed imaging studies to date include T1 mapping and T1-derived Manuscript ECV estimation.All the previous studies in CTD have been restricted to patients with advanced cardiac involvement. Together with clinical assessment and multi-imaging tests, the aim of the present study was to find markers to detect cardiac involvement before RVH presented, which could be important for guiding treatment decisions such as the timing and choice of pharmaceutical treatment. The combination of myocardial functional and tissue changes may offer further insight into the pathophysiology of CTD.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CMR examinationDiagnostic test

    After recruiting participants and collecting the baseline information, a CMR scan and a post-processed imaging procedure will be carried on in order to detect the cardiac impairment.

Study groups in NCT04297371
Study groupRoleWhat they receive
CTD with RVHThe diagnosis of CTD was made based on the clinical classification criteria. The RVH patient was diagnosed by an echocardiography demonstration (later confirmed by CMR) of a hypertrophic RV (maximal end-diastole RV wall thickness >4 mm) due to CTD.
Receives: Diagnostic Test: CMR examination
CTD without RVHThe diagnosis of CTD was made based on the clinical classification criteria.The subjects were enrolled as having non-RVH if their RV wall thickness was ≤ 4 mm (later confirmed by CMR).
Receives: Diagnostic Test: CMR examination
Control groupThe controls were healthy volunteers who have normal electrocardiographic and echocardiographic results and normal CMR findings
Receives: Diagnostic Test: CMR examination

What is being measured

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

  1. Composite endpoint of cardiac condition

    Compose of ventricular mass (g), volume (mL), ejection fraction (%) and strain (%) of both left and right ventricles.

    Measured: within 2 days of CMR scan

  2. Composite endpoint of quantitative fibrosis assessment

    Compose of percentage of extracellular volume (%) and positive rate of late gadolinium enhancement (%).

    Measured: within 2 days of CMR scan

Questions about this trial

What is this clinical trial studying?

An observational study of Connective Tissue Diseases and Right Ventricular Hypertrophy, run by RenJi 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 10 inclusion and 4 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: finished, as of the sponsor's last update on 13 Aug 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Composite endpoint of cardiac condition (time frame: within 2 days of CMR scan). The study lists 2 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.

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 13 Aug 2020; AzTrials last refreshed its copy on 8 Nov 2026.
