Trial summary

The aging of the population is a reality in our society, with a strong increase in the number of elderly patients hospitalized for heart failure in our institutions. Heart failure in these patients is more present than to younger patients, with preserved ejection fraction form (HFpEF). Read more about this study

About this study

The aging of the population is a reality in our society, with a strong increase in the number of elderly patients hospitalized for heart failure in our institutions. Heart failure in these patients is more present than to younger patients, with preserved ejection fraction form (HFpEF). Aging is responsible for the onset of senile amyloid cardiomyopathy. This pathology is still imperfectly understood and its link with the increase in the frequency of HFpEF is important. In addition, specific treatments have just shown their effectiveness. It is therefore urgent to better identify the prognostic predictive parameters of this cardiomyopathy.

The pathophysiological involvement of the coronary microcirculation responsible for a true microvascular coronary disease (CMVD) has been described as predictive factor in all cardiomyopathies. However the implementation of preventive strategies and / or therapeutic of the coronary microcirculation dysfunction are limited because we lack of diagnostic tests available and applicable to large cohorts of patients.

Our team INSERM U1039 Radiopharmaceutiques Biocliniques in collaboration with the laboratory GIPSA-lab (Grenoble Images Speech Signal Automatique), laboratory specialized in the signal analysis, has developed a new method of analysis allowing to measure the coronary microcirculation dysfunction usable in SPECT thanks to the measurement of a myocardial perfusion heterogeneity index (IHPM) (patented technique). The 3C registry (NCT03479580) is a registry studying the prevalence and cardiovascular prognosis of macro and microcirculatory coronary artery disease using the latest coronary evaluation techniques in patient with cardiomyopathy. This registry deployed on interventional cardiology centers on the Alpine Arc is therefore also addressed to patients with senile cardiomyopathy. The data collected will provide a better understanding of the factors influencing the prognosis of senile cardiomyopathy and the prognostic contribution of the measurement of the IHPM will be evaluated.

    Rate of occurrence of the primary endpoint: all-cause mortality at 1 year

    Measured: 1 year

Secondary outcomes (8)
  1. Prognostic value of IHMP on hospitalizations for heart failure in patients with senile cardiac amyloidosis.

    Rate of secondary endpoint: hospitalization for heart failure

    Measured: 1 year

  2. Prognostic value of IHPM on the quality of life in patients with senile cardiac amyloidosis

    Minnesota Quality of Life Questionnaire

    Measured: 1 year

  3. Relationships between IHPM and structural and functional measures in cardiac imaging in cardiac ultrasound

    Measurements in cardiac echography (longitudinal, radial and circumferential strain of the left ventricle in speckle tracking, left atrial strain in speckle tracking)

    Measured: Inclusion

  4. Relationships between IHPM and structural and functional measures in cardiac imaging in MRI.

    Measurement of IHPM in scintigraphy and measurements in cardiac MRI (right and left ventricular function, cardiac mass,% LV fibrosis).

    Measured: Inclusion

  5. Correlations between IHMP and geriatric frailty.

    grid SEGA-A (short emergency geriatric evaluation)

    Measured: Inclusion

  6. Relationships between IHPM in cardiac scintigraphy and the rhythmic evaluations.

    Measured: inclusion

  7. Comparison of IHPM between patients with amyloid senile cardiomyopathy and a control population paired with age and sex.

    Measurement of IHPM in myocardial scintigraphy in patients with senile cardiac amyloidosis and a control population paired with age and sex.

Questions about this trial

What is this clinical trial studying?

An observational study of Cardiac Amyloidosis, run by University Hospital, Grenoble at 1 site in France.

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 5 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 19 May 2022. 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 France. 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 Charlotte Casset, Dr (+33476763627, ccasset@chu-grenoble.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Prognostic value of myocardial perfusion heterogeneity index on mortality at 1 year in patients with senile cardiac amyloidosis. (time frame: 1 year). 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 19 May 2022.
