#1: Actually, Hyperacute T Waves Can Help Identify Occlusion MI

Spoon Feed
Hyperacute T-waves are best conceptualized as being tall and wide relative to the size of the QRS complex, as well as abnormally symmetric, and can be used to aid in early identification of an acute coronary occlusion.

Hyperacute T-waves Can Be a Useful Sign of Occlusion Myocardial Infarction if Appropriately Defined. Ann Emerg Med. 2023 Mar 3:S0196-0644(23)00025-2. doi: 10.1016/j.annemergmed.2023.01.011. Epub ahead of print.

#2: PROCOAG RCT – Early PCC for Trauma Patients at Risk of Massive Transfusion

Spoon Feed
This well-designed RCT finds early administration of 4-factor prothrombin complex concentrate (PCC) to patients at risk of receiving massive transfusion protocol (MTP) did not reduce 24-hour blood product consumption or mortality but did increase thrombotic events.

Efficacy and Safety of Early Administration of 4-Factor Prothrombin Complex Concentrate in Patients With Trauma at Risk of Massive Transfusion: The PROCOAG Randomized Clinical Trial. JAMA. 2023 Mar 21. doi: 10.1001/jama.2023.4080. Online ahead of print.

Spoon Feed
Previous guidelines suggested that isolated aVR elevation with multi-lead ST depression could be considered as a STEMI equivalent. However, current evidence suggests aVR elevation is not specific for an acute coronary event.

Does ST Elevation in Lead aVR Require an Emergent Trip to the Catheterization Laboratory? JAMA Intern Med. 2023 Mar 1;183(3):261-262. doi: 10.1001/jamainternmed.2022.5901.
