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). 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.
