ESC consensus updates temporary mechanical circulatory support guidance in cardiogenic shock

A clinical consensus statement from the European Association of Percutaneous Cardiovascular Interventions and the Association for Acute CardioVascular Care of the European Society of Cardiology updates their 2020 guidance on temporary mechanical circulatory support. Published in the European Heart Journal, it addresses acute myocardial infarction complicated by cardiogenic shock, a heterogeneous syndrome with persistently high mortality.

The abstract highlights one recent randomized controlled trial suggesting a mortality benefit from a percutaneous microaxial flow pump in patients with ST-elevation myocardial infarction and cardiogenic shock. By contrast, routine veno-arterial extracorporeal membrane oxygenation in acute myocardial infarction complicated by shock has not improved survival and has been associated with higher complication rates. Sample sizes, effect estimates, and detailed eligibility criteria are not provided in the available abstract.

The statement emphasizes phenotype-driven patient selection, incorporating SCAI and SHARC classifications to guide device choice, timing, escalation, and de-escalation. It also prioritizes multidisciplinary shock teams, regional hub-and-spoke systems, and structured escalation and futility protocols. This is consensus guidance rather than new trial evidence; without the full text, specific recommendations and the applicability of trial findings to individual patient groups cannot be assessed.
