Trial summary

In non-ischemic dilated cardiomyopathy (NIDCM), left ventricular reverse remodeling (LVRR) can be achieved through guideline-directed medical therapy (GDMT). LVRR is defined as an increase in left ventricular ejection fraction (LVEF) of more than 10% in heart failure patients with a baseline LVEF of 40% or less, or an… Read more about this study

About this study

In non-ischemic dilated cardiomyopathy (NIDCM), left ventricular reverse remodeling (LVRR) can be achieved through guideline-directed medical therapy (GDMT). LVRR is defined as an increase in left ventricular ejection fraction (LVEF) of more than 10% in heart failure patients with a baseline LVEF of 40% or less, or an increase in LVEF of more than 40% at follow-up, which is classified as heart failure with improved EF (HFimpEF) according to current guidelines. Several studies have examined the prevalence and predictors of LVRR in NIDCM. However, there is a lack of research on LVRR in the context of contemporary pharmacotherapy. Studies have demonstrated the beneficial effects of ivabradine in heart failure with reduced ejection fraction (HFrEF), improving patients' prognosis. A sub-study of the SHIFT trial indicated that ivabradine may also contribute to cardiac remodeling reversal in patients with HFrEF. However, there is limited evidence exploring the relationship between ivabradine and LVRR, particularly in the context of NIDCM.

Consequently, this study is a retrospective, multi-center cohort study aiming to evaluate the impact of ivabradine on LVRR in patients with NIDCM in the current era of medical therapy. Furthermore, by conducting this study, we aim to gain insights into the potential role of ivabradine in promoting LVRR in NIDCM patients receiving contemporary drug therapy.

What is being measured

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

  1. Prevalence of of LVRR in patients with NIDCM

    LVRR is characterized by an increase in left ventricular ejection fraction (LVEF) of more than 10% in heart failure patients with a baseline LVEF of 40% or less, or an increase in LVEF of more than 40% during follow-up, which is classified as heart failure with improved EF (HFimpEF). Furthermore, the initiation of guideline-directed medical therapy (GDMT) is defined as the timeframe for commencing treatment with an angiotensin-converting enzyme inhibitor (ACEi), angiotensin II receptor antagonist (ARB), or beta-blocker after the diagnosis of heart failure with reduced ejection fraction (HFrEF).

    Measured: at 12 months after the initiation of GDMT

Secondary outcomes (7)
  1. Prevalence of LVRR in NIDCM at 8 months after initiation of GDMT

    Measured: at 8 months after GDMT initiation

  2. Extent of LVRR (measured by LVEDD/LVESD, LAVI, E/e' in echocardiography) in NIDCM at 8 and 12 months after GDMT initiation

    Measured: at 8 and 12 months after GDMT initiation

  3. Clinical course of LVRR in NIDCM

    Measured: at 8 and 12 months after GDMT initiation

  4. Effect of targeted HR (HF <60 or 70/min) on LVRR in NIDCM at 8 and 12 months after GDMT initiation

    Measured: at 8 and 12 months after GDMT initiation

  5. Effect of degree of change in HR before and after GDMT on LVRR in NIDCM at 8 and 12 months after GDMT initiation

    Measured: at 8 and 12 months after GDMT initiation

  6. Impact of GDMT on LVRR in NIDCM at 8 and 12 months after GDMT initiation

    Measured: at 8 and 12 months after GDMT initiation

  7. Prevalence of symptomatic bradycardia, syncope, or any other adverse events with Ivabradine

    Measured: at 8 and 12 months after GDMT initiation

Questions about this trial

What is this clinical trial studying?

An observational study of Dilated Cardiomyopathy and Ventricular Remodeling, run by Yonsei University at 1 site in South Korea.

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 5 inclusion and 10 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 3 Aug 2023. 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 South Korea. 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?

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?

Prevalence of of LVRR in patients with NIDCM (time frame: at 12 months after the initiation of GDMT). 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 3 Aug 2023.
