---|---|---|---|---|
Primary | Changes in nocturnal systolic blood pressure | Comparison of blood pressure measured by 24 hour blood pressure measurements at baseline conditions (after two weeks of usual diet) and intervention (after two weeks of dietary sodium restriction) | from day 14 to day 28 | |
Secondary | Changes in day (systolic and diastolic) and 24h blood pressure (systolic and diastolic) | Comparison of blood pressure measured by 24h blood pressure measurements at baseline conditions (after two weeks of usual diet) and intervention (after two weeks of dietary sodium restriction) | from day 14 to day 28 | |
Secondary | Changes in number of nocturnal pauses in breathing (apnoea hypopnoea index, AHI) | Comparison of apnoea hypopnoea index measured by cardio respiratory monitoring at baseline conditions (after two weeks of usual diet) and intervention (after two weeks of dietary sodium restriction) | from day 14 to day 28 | |
Secondary | Changes in day:night sodium urinary sodium excretion | Comparison of baseline conditions (after two weeks of usual diet) and intervention (after two weeks of dietary sodium restriction) | from day 14 to day 28 | |
Secondary | Changes in urinary excretion of aquaporin-2 (U-AQP2) og epithelial sodium channel (u-ENaC?) | Comparison of baseline conditions (after two weeks of usual diet) and intervention (after two weeks of dietary sodium restriction) | from day 14 to day 28 | |
Secondary | Changes in endothelial function (nitric oxide (NO), erythrocyte sodium sensitivity) | Comparison of biomarkers from blood samples drawn at baseline conditions (after two weeks of usual diet) and intervention (after two weeks of dietary sodium restriction) | from day 14 to day 28 |
