Protocol-Driven Best Practices and Cardiogenic Shock Survival in Asian Patients.

Background: Cardiogenic shock carries high mortality. This study investigated the relationship between protocol-advocated best practices and outcomes.

Methods: Patients with cardiogenic shock supported by Impella CP in an Asian tertiary cardiac center were evaluated for 30-day post percutaneous ventricular assist device (PVAD) survival after adopting a standardized protocol emphasizing early mechanical circulatory support (shock-to-PVAD time ≤180 minutes), pulmonary artery catheterization for invasive hemodynamics, and safe vascular access.

Cardiac power output ratio: Novel survival predictor after percutaneous ventricular assist device in cardiogenic shock.

Aims: Currently, there is limited data on prognostic indicators after insertion of percutaneous ventricular assist device (PVAD) in the treatment of cardiogenic shock (CS). This study evaluated the prognostic role of cardiac power output (CPO) ratio, defined as CPO at 24 h divided by early CPO (30 min to 2 h), in CS patients after PVAD.

Methods And Results: Consecutive CS patients from the QEH-PVAD Registry were followed up for survival at 90 days after PVAD.
