JACC's June 10 issue, focusing on the ACS guideline, features a series of videos with unique perspectives. In this video, JACC: Executive Associate Editor Karthik Murugiah, MBBS, MHS, FACC, introduces his paper discussing the guideline's reliance on four landmark RCTs in AMI-CS. Several sweeping changes in recommendations for MCS use have been codified that should influence practice and improve care for these high-risk patients. While IABP use is expected to decrease, use of mAFP is likely to increase but should be judicious, with caution against overgeneralizing given the narrow selection criteria of DanGer Shock. Evaluating real-world practice patterns and outcomes of patients with AMI-CS based on these recommendations will be paramount.
