Implication

Observational analysis compares cardiac output measurements in postcapillary pulmonary hypertension patients, highlighting implications for all-cause mortality.

Key Points

Moderate correlations were observed between cardiac output from both measurement methods in patients with postcapillary pulmonary hypertension.
Cardiac index derived from thermodilution was associated with improved all-cause mortality risk stratification compared to the estimated Fick method.
The estimated Fick method showed poor agreements with thermodilution, indicating potential limitations in assessing cardiac output reliably.
Lower cardiac index assessed by the Dehmer formula indicates a significantly higher risk of all-cause mortality for patients with postcapillary pulmonary hypertension.
