BACKGROUND The presence and extent of microvascular obstruction (MO) after acute myocardial infarction can be measured by first-pass gadolinium-enhanced perfusion cardiovascular magnetic resonance (CMR) or after gadolinium injection with early or late enhancement (EGE/LGE) imaging. The volume of MO measured by these three methods may differ because contrast(More)
Transthoracic echocardiograms (TTE) and 24-hour Holter recordings are commonly requested investigations for patients presenting with symptoms thought to be due to underlying cardiac pathology. The objective of this study was to audit the use of inpatient TTE and Holter monitors in acute medical patients under the care of physicians other than cardiologists(More)
BACKGROUND Aberrant coronary arteries represent a diverse group of congenital disorders. Post-mortem studies reveal a high risk of exercise-related sudden cardiac death in those with an anomalous coronary artery originating from the opposite sinus of Valsalva (ACAOS) with an inter-arterial course. There is little documentation of lifetime history and(More)
KEY POINTS Dobutamine stress echocardiography is a validated tool for the non-invasive evaluation of myocardial ischaemia and enables the recording of heart rate variability in non-resting conditions. In this study we determined whether individuals with transient myocardial ischaemia had different autonomic responses to the stress of dobutamine infusion(More)
An 84-year-old man presented with continuous chest pain and hypotension. There was no previous medical history. The electrocardiogram demonstrated mild inferior STsegment depression. The serum D-dimer was markedly raised at 2512 ng/mL (normal range 0–230 ng/mL), and troponin T was elevated at 771 ng/L (normal range 0–14 ng/L), hence the patient was(More)
