Περίληψη: Background: Exercise intolerance (EI) predicts hospitalization for symptomatic heart failure (HF) in patients with type 2 diabetes mellitus (T2DM); however, cardiopulmonary exercise testing (CPET) is not always feasible in routine practice. The prognostic value of the 30-second chair stand test (CS30), a simple functional assessment correlated with peak oxygen uptake (peakVO2), remains unclear. We investigated whether the CS30 reflects exercise capacity and predicts hospitalization for symptomatic HF in patients with T2DM and stage B HF.
Methods: A total of 502 outpatients with T2DM and stage B HF were prospectively enrolled. Exercise capacity was assessed using peakVO2 from CPET and functional performance using CS30. EI was defined as peakVO2 ≤80% predicted, and abnormal-CS30 as <18 repetitions for males and <16 for females. Participants were followed for the first hospitalization for symptomatic HF. Associations were assessed using multivariable Cox models, and discrimination using the 5-year time-dependent area under the receiver operating characteristic curve (AUC).
Results: The CS30 performance was significantly associated with peakVO2. Over a median follow-up of 5.1 years, 91 patients were hospitalized for symptomatic HF. Abnormal-CS30 independently predicted hospitalization for symptomatic HF after adjustment for the WATCH-DM score, B-type natriuretic peptide, left ventricular hypertrophy, and atrial fibrillation. Adding the CS30 to resting risk models significantly improved the 5-year AUC, with performance comparable to that of EI.
Conclusions: In patients with T2DM and stage B HF, the CS30 reflected reduced exercise capacity and independently predicted hospitalization for symptomatic HF. Given its simplicity and feasibility, the CS30 may serve as a practical functional marker to complement resting risk models when CPET is unavailable.
