About this study

Official title: RESynchronizaTiOn theRapy and bEta-blocker Titration : RESTORE

Patients will be treated according to the clinical practice of the participating centers and to the international guidelines for the treatment of heart failure.The present analysis provides a collection of data about the changes to drug therapy after the "Cardiac Resynchronization Therapy" (CRT) procedure , and any signs and symptoms of intolerance to prescribed medications.

Read the detailed description

The treatment of chronic heart failure is currently based on the use of ACE (Angiotensin Converting Enzyme) inhibitors and beta-blockers. Although this therapy is universally accepted up to 10-20% of patients may be intolerant. Moreover, the majority of patients are not treated with the doses that have been shown to be effective in controlled clinical trials. Although it is possible that even low doses of neurohumoral inhibitors are still effective than placebo, a greater benefit can be obtained at maximum doses. Therefore, it is generally recommended that these agents are used at recommended doses found to be effective in controlled studies. There are many reasons for the lack of prescription neurohumoral inhibitors and their use in non-optimal doses. These include both an inadequate clinical management, and low tolerance to drugs. As far as beta-blockers, their poor tolerability has at least two main causes: 1) the effects not related to heart failure (eg, bradycardia, AtrioVentricular (AV) block, bronchial asthma), 2) the acute negative inotropic effects, which can cause a further deterioration of hemodynamic parameters.

The primary objective of the analysis is to demonstrate that cardiac resynchronization therapy (CRT) may allow titration of beta-blockers (carvedilol or bisoprolol) until the optimal dosage, or at least to the effective dose, in patients with heart failure treated to maximal doses of beta-blockers and with the indications for CRT according to current international guidelines.

The secondary objective is to evaluate the effectiveness of remote monitoring with a telemedicine system to facilitate the automatic titration of beta-blockers in comparison with the standard approach, which consists of periodic outpatient visits. The strategy adopted will depend on the availability of remote monitoring systems and standard clinical practice of each participating center.

In addition, we will evaluate the clinical response to CRT, depending on the optimal or sub-optimal dosage of beta-blockers.

What participants receive

Study groupRoleWhat they receive
Optimal beta blocker titrationWe will compare the efficacy of two management strategies for beta-blocker up-titration: Standard in-office visits vs. Remote follow-up.
Without optimal titration of beta blockerThis analysis will be conducted within the Cardiac Resynchronization Therapy observational study Modular Registry (CRT MORE - ClinicalTrials.gov Identifier: NCT01573091).

What is being measured

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

  1. Optimal beta-blockers titration due to CRT

    The primary objective of the analysis is to demonstrate that cardiac resynchronization therapy (CRT) may allow titration of beta-blockers (carvedilol or bisoprolol) until the optimal dosage, or at least to the effective dose, in patients with heart failure treated to maximal doses of beta-blockers and with the indications for CRT according to current international guidelines.The goal is to achieve the optimal dosage of 10mg/die of bisoprolol or 50mg/die of carvedilol, or at least the recommended dose (carvedilol 37.5 mg / day or bisoprolol 7.5 mg), as shown in international treatment guidelines.

    Measured: 3 months

Secondary outcomes (2)
  1. Beta-blocker Titration with telemedicine system

    The secondary objective is to evaluate the effectiveness of a Remote Patient Management (RPM) system to optimize the titration of beta-blockers in comparison with the standard approach, which consists of periodic in -hospital visits.

    Measured: 3 months

  2. Clinical response to CRT

    The response will be measured at 3 and 12 months in terms of:

    1. Amount of reverse remodeling of the left ventricle;
    2. Changes in NYHA (New York Heart Association) functional class;
    3. Ventricular arrhythmias treated by the Implantable Cardioverter Defibrillator (ICD);
    4. Adverse cardiovascular events (cardiovascular hospitalization, heart failure hospitalization) and mortality from all causes.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Beta Blocker Intolerance and Congestive Heart Failure, run by Giuseppe Ricciardi at 4 sites in Italy.

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 7 inclusion and 6 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 24 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Italy. 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?

Optimal beta-blockers titration due to CRT (time frame: 3 months). 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 NCT02173028, 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 24 Feb 2017.
