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.
