BACKGROUND: Symptom presentation has been sparsely studied from a gender perspective restricting the inclusion to ST elevation myocardial infarction (STEMI) patients. Correct symptom recognition is vital in order to promptly seek care in STEMI where fast reperfusion therapy is of utmost importance. Female gender has been found associated with atypical presentation in studies on mixed MI populations but it is unclear whether this is valid also in STEMI. OBJECTIVES: We assessed whether there are gender differences in symptoms and interpretation of these in STEMI, and if this is attributable to sociodemographic and clinical factors...

BACKGROUND: The impact on mortality due to prompt recognition of ST-segment Elevation Myocardial Infarction (STEMI) patients by EMS has not been well described. The objective of this study was to describe the association between the time interval, 9-1-1 call to percutaneous intervention (PCI), and mortality at one year. METHODS: This retrospective analysis included patients that were transported by EMS as a "code STEMI" and underwent PCI.  Total time from 9-1-1 call to PCI was calculated for each patient and was the independent variable of interest...

BACKGROUND: Sex-based differences in acute coronary syndrome (ACS) mortality may attenuate with age due to better symptom recognition and prompt care. Hypothesis Age is a modifier of temporal trends in sex-based differences in ACS care. METHODS: Among 104,817 eligible patients with ACS enrolled in the AHA GWTG-CAD registry between 2003-2008, care and in-hospital mortality were evaluated stratified by sex and age (<65 years and ≥65 years). Temporal trends within sex and age groups were assessed for two care processes: the percentage of patients with ST-elevation MI (STEMI) presenting to PCI capable hospitals with a door-to-balloon time ≤ 90 minutes (DTB90) and the proportion of eligible patients with ACS treated with aspirin within 24 hours of presentation...

OBJECTIVE: Repeated or serial 12-lead electrocardiograms (ECGs) in the prehospital setting may improve management of patients with subtle ST-segment elevation (STE) or with a ST-segment elevation myocardial infarction (STEMI) that evolves over time. However, there is a minimal amount of scientific evidence available to support the clinical utility of this method. Our objective was to evaluate the use of serial 12-lead ECGs to detect STEMI in patients during transport in a Canadian emergency medical services (EMS) jurisdiction...

BACKGROUND: Acute myocardial infarction (MI) is associated with high mortality and among survivors have high morbidity. Electrocardiogram (ECG), a cost-effective and easily available, has traditionally been used not only just for diagnosis of MI but also for culprit vessel recognition and for prognostication. However, the role of lead augmented vector right (aVR) and leads V7-V9 in acute MI are often neglected in clinical practice. We studied the role of lead aVR and leads V7-V9 in ST-elevation MI (STEMI) patients...

BACKGROUND: Hyperkalemia is a common electrolyte abnormality and has well-recognized early electrocardiographic manifestations including PR prolongation and symmetric T wave peaking. With severe increase in serum potassium, dysrhythmias and atrioventricular and bundle branch blocks can be seen on electrocardiogram. Although cardiac arrest is a worrisome consequence of untreated hyperkalemia, rarely does hyperkalemia electrocardiographically manifest as acute ischemia. CASE PRESENTATION: We present a case of acute renal failure complicated by malignant hyperkalemia and eventual ventricular fibrillation cardiac arrest...

Current guidelines recommend that patients with non-ST elevation myocardial infarction (NSTEMI) are treated with medical management alone, or in combination with coronary angiography within 24 h. Recent research suggests that NSTEMIs show angiographic evidence of complete occlusion at rates comparable to STEMIs, suggesting a subgroup of NSTEMI patients who require urgent angiography. Novel ECG changes, termed 'STEMI-equivalents', have been described as a way of identifying this subgroup. The aim of this study was to determine whether patients with STEMI-equivalent ECG changes experience similar degrees of myocardial damage, and would thus benefit from urgent PCI...

Recognition and identification of the cause of non-coronary ST elevation is important in daily practice, mainly for avoiding unnecessary diagnostic and therapeutic procedures. In this case, a rare cause, spontaneous, left sided tension pneumothorax was in the background of the suddenly appearing, complex ECG changes - ST elevation mimicking inferior wall myocardial infarction associated with type 1 Brugada pattern ("coved" ST-segment elevation ≥ 2 mm) in the precordial leads. The clinical picture and course, the differential diagnostic problems related to the case and the possible causes of the ECG changes will be presented...

The AngelMed Guardian System is an implantable device similar to a single chamber pacemaker that continuously monitors the intracardiac electrogram for evidence of ST segment shift indicating acute coronary artery occlusion. The system aims to reduce time to presentation by alerting patients to present to a medical facility whether symptoms are present or not. In March 2016, the US Food and Drug Administration (FDA) assembled a meeting of the Circulatory System Devices Panel to review the results of the AngelMed for Early Recognition and Treatment of STEMI (ALERTS) pivotal trial and the accompanying premarket approval (PMA) application for regulatory approval of the AngelMed Guardian System in the US...

The concept of the 'vulnerable plaque' originated from pathological observations in patients who died from acute coronary syndrome. This recognition spawned a generation of research that led to greater understanding of how complicated atherosclerotic plaques form and precipitate thrombotic events. In current practice, an increasing number of patients who survive their first event present with non-ST-segment elevation myocardial infarction (NSTEMI) rather than myocardial infarction (MI) with ST-segment elevation (STEMI)...

ST-elevation myocardial infarction (STEMI), which constitutes nearly 25-40 % of current acute myocardial infarction (AMI) cases, is a medical emergency that requires prompt recognition and treatment. Since the 2013 STEMI practice guidelines, a wealth of additional data that may further advance optimal STEMI practices has emerged. These data highlight the importance of improving patient treatment and transport algorithms for STEMI from non-primary percutaneous coronary intervention (PCI) centers. In addition, a focus on the reduction of total pain-to-balloon (P2B) times rather than simply door-to-balloon (D2B) times may further improve outcomes after primary PCI for STEMI...

Karim D Mahmoud, Felix Zijlstra
The success of primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) is often hampered by incomplete microvascular myocardial reperfusion owing to distal embolization of thrombus resulting in microvascular obstruction. To address this problem, thrombus aspiration devices have been developed that can be used to evacuate coronary thrombus either manually or mechanically. Thrombus aspiration has the potential to reduce the local thrombus load, minimize the need for balloon predilatation, facilitate direct stenting, prevent distal embolization, and ultimately improve myocardial reperfusion...

BACKGROUND: The appropriate management of patients with ST-segment elevation myocardial infarction (STEMI) depends on accurate interpretation of the 12-lead ECG by paramedics. Computer interpretation messages on ECGs are often provided, but the effect they exert on paramedics' decision-making is not known. The objective of this study was to assess the feasibility of using an online assessment tool, and collect pilot data, for a definitive trial to determine the effect of computer interpretation messages on paramedics' diagnosis of STEMI...

BACKGROUND: Early recognition of viable myocardium after acute myocardial infarction (AMI) is of clinical relevance, since affected segments have the potential of functional recovery. Delayed contrast-enhanced magnetic resonance imaging (DCE-CMR) has been validated extensively for the detection of viable myocardium. An alternative parameter for detecting viability is the perfusable tissue index (PTI), derived using [(15)O]H2O positron emission tomography (PET), which is inversely related to the extent of myocardial scar (non-perfusable tissue)...

Primary percutaneous coronary intervention (PCI) has become the treatment of choice in patients with ST-segment elevation myocardial infarction (STEMI) throughout the last years. A significant number of studies have demonstrated a morbidity and mortality benefit over thrombolysis, which has been attributed to better coronary perfusion in patients undergoing primary PCI. Even though it usually achieves normal flow in the affected epicardial vessel, myocardial reperfusion is not fully restored in a significant percentage of patients...

Timely reperfusion therapy by means of primary percutaneous coronary intervention (PCI) is the preferred treatment for patients with ST-segment elevation myocardial infarction. A significant number of patients with large acute myocardial infarction, caused by occlusion of an epicardial coronary artery, do not show ST-elevation on the electrocardiogram. Other ECG abnormalities may be present, the so called STEMI-equivalents. One such STEMI equivalent, junctional ST-segment depression followed by tall symmetrical T-waves in the precordial leads, often in combination with slight ST-elevation in lead AVR, has been associated with proximal occlusion of the left anterior descending coronary artery...
