ClinicalTrials.gov, NCT00712101 and NCT01612312 Defining remote segments (R) in the presence of infarct areas (I) for the analysis of remote circumferential strain (CS). Remote CS was significantly lower in patients who suffered major adverse cardiac events (MACE) and a cutoff value for remote CS of - 25.8% best identified high-risk patients. In addition, impaired remote CS ≥ - 25.8 % (Remote -) and preserved remote CS < - 25.8 % (Remote +) enabled further risk stratification when added to established parameters like left ventricular ejection fraction (LVEF), global circumferential strain (GCS) or microvascular obstruction (MVO).
