Design outcomes
Primary
| Measure | Time frame |
|---|---|
| I Evaluation of internal and external cardiac power using cardiac MRI in patients with heart failure with reduced (HFrEF), midrange (HFmrEF) and preserved (HFpEF) ejection fraction. II. Measurement of the aortic valve pressure gradient. III. Measurement of contraction time. IV. Measurement of endsystolic and enddiastolic cardiac blood volume. V. Measurement of myocardial thickness and calculation of myocardial wall tension. VI. Measurement of myocardial wall mass and mass index. VII. Calculation of aortic compliance using pulse wave velocity and area change of aorta ascendens and descendens during systole and diastole in patients with heart failure with reduced (HFrEF), midrange (HFmrEF) and preserved (HFpEF) ejection fraction. VIII. Evaluation of cardiac output calculating the product of heart rate and stroke volume using cardiac MRI in patients with heart failure with reduced (HFrEF), midrange (HFmrEF) and preserved (HFpEF) ejection fraction. XI. Measurement of extracellular volume as a diffuse marker of fibrosis. X. Subjective description of dyspnea initially in person and during follow up in phone visits if patients consents. | — |
