Management Strategies and Outcomes of ST‐Segment Elevation Myocardial Infarction Patients Transferred After Receiving Fibrinolytic Therapy in the United States

摘要

Fibrinolytic therapy is still used in patients with ST-segment elevation myocardial infarction (STEMI) when the primary percutaneous coronary intervention cannot be provided in a timely fashion. Management strategies and outcomes in transferred fibrinolytic-treated STEMI patients have not been well assessed in real-world settings. Using the Nationwide Inpatient Sample from 2008 to 2012, we identified 18 814 patients with STEMI who received fibrinolytic therapy and were transferred to a different facility within 24 hours. The primary outcome was in-hospital mortality. Secondary outcomes included gastrointestinal bleeding, bleeding requiring transfusion, intracranial hemorrhage (ICH), length of stay, and cost. The patients were divided into 3 groups: those who received medical therapy alone (n = 853; 4.5%), those who underwent coronary artery angiography without revascularization (n = 2573; 13.7%), and those who underwent coronary artery angiography with revascularization (n = 15 388; 81.8%). Rates of in-hospital mortality among the groups were 20% vs 6.6% vs 2.1%, respectively ( P
