Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Left ventricular strains and twist/untwist kinetics during the transitions from rest to exercise, measured non-invasively using 2D-strain echocardiography. Each subject of the study was evaluated one time only (i.e. transversal design) | — |
Secondary
| Measure | Time frame |
|---|---|
| Global systolic and diastolic functions, measured non-invasively using Doppler echocardiography. Each subject of the study was evaluated one time only (i.e. transversal design) | — |
