A uniform policy for regionalization of ST-segment elevation myocardial infarction (STEMI) care raises several concerns. Transferring all STEMI patients to obtain primary percutaneous coronary intervention (PCI) may be less effective than transferring only high-risk STEMI patients. Delays in time to treatment >60 min associated with transferring patients for primary PCI may result in increased ...

OBJECTIVES The aim of this retrospective study was to compare clinical and angiographic outcomes between patients presenting with ST-segment elevation myocardial infarction (STEMI) due to stent thrombosis (ST) and de novo coronary thrombosis. BACKGROUND There are limited data for procedural and mid-term outcomes of patients with ST presenting with STEMI. METHODS From January 2004 to March 2...

OBJECTIVE To describe patterns of prehospital ECG (PHECG) use and determine its association with processes and outcomes of care in patients with ST-elevation myocardial infarction (STEMI) and non-STEMI. METHODS Population-based linked cohort study of a national myocardial infarction registry. RESULTS 288 990 patients were admitted to hospitals via emergency medical services (EMS) between 1 ...

BACKGROUND Homocysteine has been long considered a risk factor for atherosclerosis. However, cardiovascular events cannot be reduced through homocysteine lowering by B vitamin supplements. Although several association studies have reported an elevation of serum homocysteine levels in cardiovascular diseases, the relationship of homocysteine with ST-segment elevation myocardial infarction (STEMI...

BACKGROUND There are limited contemporary data comparing long-term outcomes after cardiac catheterization for ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI). METHODS AND RESULTS We studied patients undergoing cardiac catheterization for STEMI (n=2413) and NSTEMI (n=1974) between 1999 and 2005 with at least 1 significant coronary lesion > or =75%. We compared adjuste...

Objectives The volume of ST-Segment Elevation Myocardial Infarctions (STEMIs) presenting to an emergency department (ED) has been shown to affect treatment quality measures and patient outcomes. Almost half of ST-elevation-myocardial-infarction (STEMI) patients in New Brunswick (NB) present directly to community hospitals. This study seeks to determine if the quality of care received by STEMI p...

OBJECTIVE The best strategy in patients with acute ST-segment elevation myocardial infarction (STEMI) with multivessel coronary artery disease (CAD) regarding completeness of revascularisation of the non-culprit lesion(s) is still unclear. To establish which strategy should be followed, survival rates over a longer period should be evaluated. The aim of this study was to investigate whether com...

BACKGROUND Although considered the evidence-based best therapy for ST-segment elevation myocardial infarction (STEMI), many patients do not receive primary percutaneous coronary intervention (PCI) because of health care resource distribution and constraints. This study describes the clinical management and outcomes of all patients identified with STEMI within a region, including those who did n...

Background: Historically bare metal stents were considered standard of care for STsegment elevation acute myocardial infarction (STEMI). There is limited data on STEMI patients treated for primary angioplasty with ResoluteTM zotarolimus-eluting stent (R-ZES) and the everolimus-eluting stent (EES). Methods: The global RESOLUTE program enrolled STEMI patients in 4 trials: RESOLUTE-All Comers (RAC...

BACKGROUND Ischaemic mitral regurgitation (IMR) is a detrimental complication of ST elevation myocardial infarction (STEMI). OBJECTIVE We sought to determine patient characteristics and outcomes of patients with IMR with focus on anterior or inferior location of STEMI. METHODS All patients presenting with STEMI complicated by IMR to our centre who underwent primary percutaneous coronary int...
