Among Unstable Angina and Non-ST Elevation MI Patients Transient Myocardial Ischemia and Early Invasive Treatment are Predictors of Major In-Hospital Complications

摘要

BackgroundTreatment for unstable angina (UA) or non-STEMI (NSTEMI) is aimed at plaque stabilization to prevent infarction. Two treatment strategies are: (1) invasive (i.e., cardiac catheterization laboratory < 24 hours after admission), or (2) selectively invasive (i.e., medications with cardiac catheterization laboratory > 24 hours for recurrent symptoms). However, it is not known if the frequency of transient myocardial ischemia (TMI), or complications during hospitalization varies by treatment.
