RCT: In patients with cardiogenic shock receiving VA-ECMO, moderate hypothermia did not significantly reduce 30-day mortality. 42% of patients in the moderate hypothermia group died vs. 51% in the normothermia group (adjusted odds ratio, 0.71 [95% CI, 0.45 to 1.13], P = .15).

In this RCT, for patients with cardiogenic shock receiving venoarterial ECMO, moderate hypothermia for 24 hours compared with normothermia did not significantly decrease 30-day mortality. https://t.co/0LKYJ1bNB3 pic.twitter.com/KmXPAlvqh9
