BACKGROUND Long-term outcomes of drug-eluting stents (DES) versus bare-metal stents (BMS) in patients with ST-segment elevation myocardial infarction (STEMI) remain uncertain. OBJECTIVE To investigate long-term outcomes of drug-eluting stents (DES) versus bare-metal stents (BMS) in patients with ST-segment elevation myocardial infarction (STEMI). METHODS We performed search of MEDLINE, EMBA...
BACKGROUND Thrombectomy for the treatment of ST elevation myocardial infarction (STEMI) is a simple and intuitive idea. In the 2000s, several studies evaluated the efficacy of thrombus aspiration and showed that thrombus aspiration led to improved myocardial perfusion, as assessed by a range of surrogate endpoints. These findings were confirmed by meta-analyses. However, the favorable results w...
Characteristic electrocardiogram (ECG) features of posterior myocardial infarction (PMI) do not include typical ST-segment elevation and, therefore, carries the risk of delayed diagnosis and management. The aim of this study was to investigate how well PMIs are recognised and whether a lack of recognition translates to a larger infarction. This was a retrospective cohort study of patients sourc...
Background Clinical outcome after acute ST-elevation myocardial infarction (STEMI) has been shown to be predictable by myocardial salvage index (MSI) and microvascular obstruction as determined by cardiac magnetic resonance imaging (CMR). In the setting of non-ST-elevation myocardial infarction (NSTEMI) prognostic significance is less well investigated. Due to comparable incidence of major adve...
Acute myocardial infarction can be defined from a number of different perspectives related to clinical, electrocardiographic, biochemical and pathological characteristic. The electrocardiogram (ECG) is the most important diagnostic tool in the diagnosis of ST-segment elevation myocardial infarction (STEMI), and therefore it should be accomplished immediately at hospital admission. In fact, it r...
OBJECTIVE To investigate the specificity of the electrocardiographic diagnosis of ST-segment elevation myocardial infarction in the critical care unit setting. DESIGN Retrospective observational cohort analysis. SETTING An 880-bed tertiary care teaching hospital with 120 intensive care unit beds. PATIENTS The population included medical, surgical, trauma, and neurosurgical intensive care ...
OBJECTIVES This study sought to evaluate the potential utility of a novel polyethylene terephthalate micronet mesh-covered stent (MGuard) in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). BACKGROUND Suboptimal myocardial reperfusion after PCI in STEMI is common and results in increased infarct size and mortality. The...
BACKGROUND The value of prehospital initiation of glycoprotein IIb/IIIa inhibitors remains a controversial issue. We sought to investigate whether in-ambulance initiation of abciximab in patients with ST-segment elevation myocardial infarction (STEMI) improves ST-segment elevation resolution (STR) after primary percutaneous coronary intervention (PCI). METHODS AND RESULTS MISTRAL (Myocardial ...
BACKGROUND The best treatment approach for ST-segment elevation myocardial infarction (STEMI) is prompt primary percutaneous coronary intervention (PCI). However, some patients show ST elevation on electrocardiography (ECG), but do not have myocardial infarction. We sought to identify the frequency of and to develop a prediction model for false-positive STEMI. METHODS This study was conducted...
CONTEXT Randomized trials provide robust evidence for the impact of pharmacological and interventional treatments in patients with ST-segment elevation and non-ST-segment elevation acute coronary syndromes (NSTE ACS), but whether this translates to changes in clinical practice is unknown. OBJECTIVE To determine whether changes in hospital management of patients with ST-segment elevation myoca...
