Delay to Hospital Presentation for Patients with Non%u2013ST-Segment Elevation Myocardial Infarction

Delay from Symptom Onset to Hospital Presentation for Patients with Non–ST-Segment Elevation Myocardial Infarction
Journal: Archives of Internal Medicine (November 8, 2010)
Authors: Ting H, Chen A, Roe M, et al
Purpose: Though “secular trends and factors associated with delay time from symptom onset to hospital presentation are known for patients with ST-segment elevation myocardial infarction,” they “are less well-described for non-STEMI.”
Results: The authors “studied 104,622 patients with non-STEMI enrolled at 568 hospitals participating in the Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the American College of Cardiology/American Heart Association Guidelines” over a six-year period and found that “lond delay times are common and have not changed over time for patients with non-STEMI” in large part because “patients cannot differentiate whether symptoms are due to STEMI or non-STEMI.” This highlights the importance of “early presentation…in both instances.”
