A global work index (GWI) of <500 mm Hg% was a predictor of severely impaired ejection fraction, very low exercise capacity, and strongly elevated NT-pro-BNP in patients with heart failure.

Does global work index (GWI) correlate with established prognostic parameters in patients with heart failure?
Global work index (GWI) <500 mm Hg% correlates with established prognostic markers in heart failure, suggesting its potential utility in identifying patients with poor prognosis.
AIM: Identification of patients with heart failure and a poor prognosis is paramount to ensure timely and adequate treatment. We investigated the relationship between the new measures of noninvasive pressure-strain analysis, such as the global work index (GWI), and established prognostic parameters of echocardiography, cardiopulmonary exercise test (CPX), and N-terminal pro-B-type natriuretic peptide (NT-pro-BNP). METHODS AND RESULTS: 15.6 ± 4.2 mL/min/kg). CONCLUSION: GWI correlates with known prognostic markers of heart failure. A GWI of <500 mm Hg% was a predictor of severely impaired ejection fraction, very low exercise capacity, and strongly elevated NT-pro-BNP, indicating a poor prognosis.
Hedwig et al. (Thu,) conducted a observational in Heart failure. Global work index (GWI) was evaluated on Correlation with established prognostic parameters (ejection fraction, exercise capacity, NT-pro-BNP). A global work index (GWI) of <500 mm Hg% was a predictor of severely impaired ejection fraction, very low exercise capacity, and strongly elevated NT-pro-BNP in patients with heart failure.
