One-minute sit-to-stand test cut-offs for risk stratification based on six-minute walk test thresholds in pulmonary hypertension.

Aims: We aimed to establish one-minute sit-to-stand test (1-min STST) cut-off values that align with the guideline-recommended six-minute walk test (6MWT) thresholds (165m and 440m) for one-year mortality risk stratification in pulmonary hypertension (PH) patients. Furthermore, we aimed to compare clinical characteristics and long-term mortality among patients stratified by these proposed 1-min STST cut-offs.

Methods: All patients performed the 1-min STST and 6MWT.

Correction: Functional capacity testing in patients with pulmonary hypertension (PH) using the one-minute sit-to-stand test (1-min STST).

Functional capacity testing in patients with pulmonary hypertension (PH) using the one-minute sit-to-stand test (1-min STST).

Background: The one-minute sit-to-stand-test (1-min STST) is a quick, space saving test to evaluate functional capacity. Exercise testing plays an important role in the long-term follow-up of pulmonary hypertension (PH) patients and is currently evaluated using the six-minute-walk-test (6MWT). The aim of the study was to assess the convergent validity of the 1-min STST in patients with PH and its association with markers of PH severity.
