Radiomics features could be especially useful for determining TSS in scenarios where clinical data is lacking or unreliable, such as when patients have altered mental status.

Extracorporeal CPR for out-of-hospital cardiac arrest: New research fails to provide answers

While a previous study had found that extracorporeal CPR outperformed conventional CPR among patients with out-of-hospital cardiac arrest, a newer analysis suggests the two treatment options result in similar outcomes. 

New stamp-sized wearable device uses AI to deliver on-the-go cardiac imaging

The device, designed to be worn for up to 24 hours at a time, uses ultrasound technology and artificial intelligence to track how much blood the user's heart is pumping.
