Although a diagnosis of acute myocardial infarction (AMI) that mandates emergency reperfusion therapy requires ST-segment elevation greater than 1 mm in at least 2 contiguous leads, some of the early electrocardiogram (ECG) changes of AMI can be subtle. Any ST-segment depression or T-wave inversion in lead aVL may be implicated ...

Coronary spasm is an important and often overlooked etiology of chest pain. Although coronary spasm, or Prinzmetal's angina, has been thought of as benign, contemporary studies have shown serious associated adverse outcomes, including acute coronary syndrome, arrhythmia, and death. Definitive diagnosis of coronary spasm can at times be difficult, given ...

Peripartum cardiomyopathy (PPCM) has a remarkable potential for recovery. It may be within our capability to help almost all women with PPCM not only to survive, but also to completely recover heart function. Time-of-diagnosis left ventricular ejection fraction (LVEF) ≥0.35 is associated with better survival rates and higher full recovery ...

Abstract Biomarkers play a critical role in the diagnosis of acute myocardial infarction (AMI), especially in patients with atypical clinical and/or electrocardiographic presentation or co-morbidities, like the elderly. High-sensitivity assays based on specific biomarkers (e.g. cardiac troponins) enabling earlier AMI diagnosis have recently become available in clinical practice. Although no ...

Myocardial infarction (MI) is the leading cause of death in the developed world. Biomarkers have an essential role in diagnosis, risk stratification, guiding management and clinical decision making in the setting of patients presenting with signs and symptoms of MI. Cardiac troponin (cTn) rose to prominence during the 1990s and ...

In the past ten years, primary percutaneous coronary intervention (PCI) has replaced thrombolysis as the revascularisation strategy for many patients presenting with ST-segment elevation myocardial infarction (STEMI). However, delivery of primary PCI within evidence-based timeframes is challenging, and health-care provision varies substantially worldwide. Consequently, even with the ideal circumstances of ...

Small non-coding microRNAs (miRNAs) are important physiological regulators of post-transcriptional gene expression. miRNAs not only reside in the cytoplasm but are also stably present in several extracellular compartments, including the circulation. For that reason, miRNAs are proposed as diagnostic biomarkers for various diseases. Early diagnosis of acute coronary syndrome (ACS), ...

Thin cap fibroatheromas (TCFAs) are thought to be the most common underlying substrate in patients suffering acute coronary thrombotic events. Recently, an interesting association between TCFAs and a particular depot of visceral fat called epicardial adipose tissue (EAT) has been suggested. In this article, we discuss some basic and clinical ...

Idiopathic ventricular tachycardia (VT) refers to VT occurring in structurally normal hearts. It is commonly seen in young patients and typically has a benign course. Because the origin is typically focal and the heart is without scar, the 12-lead electrocardiogram is extremely useful for localizing the origin of idiopathic VT. ...

Dynamic ischemic-type electrocardiographic T-wave inversions raise the possibility of myocardial ischemia or infarction but are actually a nonspecific finding. We present a case of a young man presenting with headache and dizziness found to have marked hypertension, deepening T-wave inversions, and troponin elevation. Initial concerns were for acute coronary syndrome ...

We present a patient who had a wide QRS tachycardia; it was initially difficult to determine whether it was superventricular tachycardia (SVT) or ventricular tachycardia (VT). By some criteria (sinus capture beats, pseudo-δ waves and wide QRS) the patient's ECG was suggestive of VT of epicardial origin. On the coronary ...

Rapid and correct diagnosis of acute myocardial infarction (AMI) plays a crucial role in saving patients' life. Although some biomarkers (such as cardiac troponin and creatine kinase) are available for AMI diagnosis so far, there is still a clinical need for novel biomarkers, which can reliably rule in or rule ...

We report a patient who presented with takotsubo cardiomyopathy but was misdiagnosed as an anterior wall ST elevation myocardial infarction (AWMI). We illustrate how misdiagnosis led to mismanagement by initiating intravenous inotropic agents that led to further hemodynamic compromise. Subsequent withdrawal of the inotropic agents and simultaneous administration of oral ...
