ABSTRACT
BACKGROUND:
Heart failure with preserved ejection fraction (HFpEF) is a major cause of morbidity and mortality. Precise risk stratification remains challenging. The one-minute sit-to-stand-test (1-min STST), a quick, objective test of functional capacity may be helpful for stratification of clinical profile in HFpEF patients.OBJECTIVE:
The aim of this initial investigation was to prospectively examine whether the 1-min STST can be used for the evaluation of exercise capacity in HFpEF patients and whether it is in line with echocardiographic as well as quality of life (QoL) findings.METHODS:
39 HFpEF patients were prospectively studied. Functional performance was examined with the 1-min STST and QoL with the CAMPHOR questionnaire. Clinical parameters including echocardiographic measurements [estimated pulmonary artery systolic pressure (ePASP), tricuspid regurgitation velocity (TRV)] were obtained. Patients were divided into two groups based on their number of 1-min STST repetitions (Group I ≤50% of predicted 1-min STST repetitions using the norm-reference values developed by Strassmann et al. for healthy people, N=24; Group II >50% of predicted 1-min STST repetitions, N=15).RESULTS:
Patients in group I with limited 1-min STST performance showed worse echocardiographic parameters [higher ePASP (p=0.038), higher TRV (p=0.018) and more reduced tricuspid annular plane systolic excursion (TAPSE) (p=0.001)], worse six-minute walk test (6MWT) (p<0.001) and worse QoL (p<0.001) compared to patients in group II.CONCLUSION:
Our study shows potential usefulness of the 1-min STST as an evaluative tool for exercise capacity in HFpEF patients, because patients with worse 1-min STST performance have worse clinical parameters and QoL.Palabras clave
