- Masking: None
- Phase: None
- Number of Arms: None

Eligibility Criteria:
Inclusion Criteria:~* Age \> 18 years~* Unclear etiology of dyspnea with non-invasive testing~* HFA-PEFF score 2-4 points and thus an intermediate risk for HFpEF~* Willingness to participate and obtained written consent~Exclusion Criteria:~* Consent for study participation not obtained~* Age \< 18 years~* Medical contraindications to perform right heart catheterization

Study Arms:
- Patients with intermediate risk for HFpEF at rest (Type: None): Patients with a HFA-PEFF score of 2-4 points and no obvious extracardiac explanation for exercise-induced dyspnea. Right heart catheterization with be performed at rest and during stress testing.

Based on this trial design, predict the completion outcome and termination type (if applicable).
