Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the morphological, biochemical and functional repercussions of Diflunisal treatment in patients with transthyretin cardiac amyloidosis.;Secondary Objective: To assess the safety and tolerability of Dflunisal 250mg / 12 hours for 1 year.;Primary end point(s): The primary analysis of the study will be the change in extracellular volume (CVD) measured by magnetic resonance using a T1 mapping technique before and after contrast at baseline and at 12 months of treatment.;Timepoint(s) of evaluation of this end point: 12 months | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): o Ejection fraction. o Ventricular thicknesses. o Necrotic / fibrotic area, defined as late Gadolinium uptake (high intensity STIR signals). o Functional class determined by the 6-minute walk test. o Score of the Kansas City Cardiomyopathy Questionnaire NT-proBNP levels. o High sensitivity C-reactive protein levels o High sensitivity Troponin levels o Serum TTR concentration o Proportion and description of Adverse Events. o Proportion of adherence to treatment. o Incidence of heart failure, death, or any acute coronary syndrome (IAMCEST or Acute coronary syndrome without ST elevation). ;Timepoint(s) of evaluation of this end point: 3, 6 and 9 months | — |
