Does the Mechanical Support Device Matter in Cardiogenic Shock Complicating AMI?

Thirty-day mortality was about 50% in patients with acute myocardial infarction and cardiogenic shock who received either an intra-aortic balloon pump or a percutaneous ventricular assist device.

The utility of intra-aortic balloon pumps (IABPs) for circulatory support in patients with cardiogenic shock has not been observed in clinical trials. Nevertheless, IABP use remains frequent. Another form of circulatory support is Impella CP (maximum output, 3.7 L/minute), a percutaneous ventricular assist device (PVAD). In the randomized IMPRESS trial comparing this device with IABP, Dutch researchers enrolled 48 mechanically ventilated patients (mean age, 58; 79% male) with ST-elevation myocardial infarction (STEMI) and cardiogenic shock being treated with primary percutaneous intervention (PCI).

Catecholamine support was given to 96% of patients; prerandomization cardiac arrest occurred in 92%. Except for eight patients, PVAD or IABP plac…
