PCI in NSTEMI

Patients with non-ST elevation myocardial infarction who are managed noninvasively at presentation or are catheterized but without revascularization represent a heterogeneous and understudied population. We evaluated the clinical characteristics, management strategies, and outcomes of patients with non-ST elevation myocardial infarction (NSTEMI) who were enrolled in the prospective biannual Acute Coronary Syndrome Israeli Surveys from 2004 to 2013. Patients were divided into 3 groups: no catheterization (no angio), catheterization with revascularization (angio-revascularized), and catheterization without revascularization (angio-nonrevascularized) groups...

BACKGROUND: Immediate invasive approach for non-ST-segment elevation myocardial infarction (NSTEMI) may permit treatment of the underlying plaque rupture as early as possible with subsequent reduction of death and myocardial infarction (MI). We sought to assess clinical impact of immediate percutaneous coronary intervention (PCI) for NSTEMI. METHODS: A total of 6134 NSTEMI patients undergoing PCI from the Korea Acute Myocardial Infarction Registry were divided into group 1 (immediate PCI within 4h, n=1132) and group 2 (non-immediate PCI after 4h, n=5002)...
