Usefulness of the Admission Shock Index for Predicting Short-Term Outcomes in Patients With St-Segment Elevation Myocardial Infarction

This study investigated using the shock index (SI) as a risk-stratification tool for patients who present within 12 h of symptom onset for acute ST-segment elevation myocardial infarction (STEMI). Using receiver operating characteristic curves, the investigators defined an SI of 0.7 as the cutoff for risk stratification, with a higher number indicating a higher-risk patient. The primary outcomes of the study were all-cause mortality at 7 and 30 days. The secondary outcomes included life-threatening dysrhythmias, heart failure, re-infarction, recurrent myocardial ischemia, stroke, bleeding, and major adverse cardiac events (MACE) within 7 and 30 days of initial hospitalization.
