Cardiac Amyloidosis pRevaleNce of in OLDer Subjects Affected by Heart Failure

Patients recruitment will be curry out in 31 geriatric or cardiologic centres. Patients will be recruited for 24 months. Each patient will participate in the study for 12 months (baseline visit, follow-up phone calls every 3 months up to 12 months i.e., at 3, 6, 9 and 12 months). The following data will be collected at teh baseline visit: Medical history, demography, clinical data, frailty status assessed by Fried, Triage Risk Screening Tool (TRST), triggers for cardiac decompensation, biological examination, genetic testing, echocardiographic data and other data. Bone scanning with 99mTc-DPD or 99mTc-HMDP (early or late time with SPECT will be done during hospitalization or after discharge depending on availability at the imaging centre. The results of each examination will be evaluated to establish the existence and degree of fixation in the myocardium and to determine its distribution. Follow-up phone s will be conducted every 3 months up to 12 months to collect hospitalizations for heart failure, hospitalizations for other cardio-vascular events, hospitalizations for non-cardiac events, admission to nursing homes or long-term care (LTC) facilities and death
