Cardiovascular Critical Care I

However, for patients with SCAI Stages C–E cardiogenic shock, using pulmonary artery catheter-

derived hemodynamic data has been associated with improved mortality (J Am Coll Cardiol HF

2020;8:903-13).

A recent prospective trial showed that providers, regardless of training level (intern to advanced HF

attending), do not accurately identify cardiogenic shock on physical examination alone. The positive

and negative predictive values of clinical assessment compared with right heart catheterization in

cardiogenic shock were 74.7% and 50.4% (J Card Fail. 2020;26(2):128-135).

Diligent use and skilled interpretation of these technologies, together with patient assessment, can be

used to guide therapeutic interventions.

See comparisons of invasive and minimally invasive hemodynamic monitoring devices (Table 2 in the

Shock Syndromes I chapter).
