Conditions
Brief summary
The INERTIA trial is a multicenter double-blinded randomized trial of intravenous iron supplementation in patients with severe aortic stenosis and iron deficiency undergoing TAVI or SAVR. The primary endpoint is the time to HF hospital admission or cardiovascular death. Secondary endpoints will assess quality of life indicators and functional capacity at 6 months.
Interventions
Intravenous ferric carboxymaltose according to baseline weight and hemoglobin

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients with heart failure hospital admission or cardiovascular death | up to 52 weeks | Analyzed as time-to-event |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Total number of allogeneic RBC units received | 30 days post-TAVI or SAVR | — |
| Walking distance | 6 months post-TAVI or SAVR | 6 minute walking test |
| Kansas City Cardiomyopathy Questionnaire | 6 months post-TAVI or SAVR | Heart failure symptoms assessment. 0-100 scale, higher scores reflect better health status. |
| Patient Global Assessment | 6 months post-TAVI or SAVR | Patient reported outcome on the impact of the disease in daily live |
| EQ-5D-5L | 6 months post-TAVI or SAVR | Quality of life assessment in five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. |
