Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Aim of this cohort study is to identify subgroups of patients with heart failure with preserved or mildly reduced ejection fraction (HFpEF/ HFmrEF) to allow a better characterisation of the disease and develop individualized therapeutic concepts that can be evaluated in pilot studies. A comparison group will be recruited with participants that show risk factors for cardiovascular disease but have no heart failure manifestation. | — |
