The investigators plan to investigate the feasibility and validity of tests of exercise capacity, when these are performed in hospital and at home, by patients who are diagnosed with pulmonary hypertension.
Patients with pulmonary hypertension develop high blood pressure within the lungs, leading to a limitation in the amount of exercise they are able to perform. At diagnosis and follow-up patients routinely perform short exercise tests which are performed under supervision in the clinic or hospital. The results from these are compared over time and are used to assess how stable patients are. Currently, patients are required to travel to hospital to perform such a test and thus telephone or video appointments do not include this information. This study aims to investigate a range of exercise tests to assess whether they are valid in pulmonary hypertension (whether the results are comparable to the results from the current exercise test performed in hospital, the six-minute walk test) and whether it is feasible for patients to to perform these tests at home.
The investigators aim to investigate four different home exercise tests, including a sit-to-stand test, a timed up and go test, a six-minute walk test and a step test. The investigators will ask patients to perform these tests in a hospital environment and at home on two occasions. The results of these will be compared to see how they change over time and will be compared to other results obtained during standard care. Additionally, patients will be asked a questionnaire to assess their views on the four tests.

| Cross-sectional assessment of novel exercise test validity (part 1) | During the inpatient hospital visit (visit 1), correlation will be analysed between the distance (metres) walked on a six-minute walk test and the outcome of each of the study tests (as listed below).
| 2 years |
| Cross-sectional assessment of novel exercise test validity (part 2) | Agreement will be analysed between each of study tests when performed during visit 1 (inpatient hospital visit) and when performed during visit 2 (within 7 days of being discharged from hospital). This will be performed with Bland-Altman analysis. | 2 years |
| Longitudinal study of feasibility | Proportion of patients that completed each of the allocated tests at visit 2 and at visit 3 (3 months after being discharged from hospital). | 2 years |
| Longitudinal study of validity | Concordance of change will be analysed between each of study tests when performed during visit 2 (and when performed during visit 3. This degree of change will be compared against the patients standard six minute walk test result when measured at visit 1 and visit 3. | 2 years |
