Around half of the patients undergoing an elective coronary angiogram to investigate typical stable angina symptoms are found have non-obstructive arteries (defined as < 50% stenosis). These younger with a female predilection. While underlying mechanisms responsible for these presentations heterogeneous, structural and functional abnormalities microvasculature highly prevalent. Thus, microva...

AIMS To evaluate the efficacy of biochemical parameters in different fluids in the diagnosis of myocardial infarction of different causes, analysed after death. METHODS The myoglobin concentration and total creatine kinase (CK) and creatine kinase MB isoenzyme (CK-MB) activities were measured in serum, pericardial fluid, and vitreous humour from seven diagnostic groups of cadavers classified ...

The incidence of perioperative myocardial ischaemia in patients with coronary artery disease, as reported in the literature, varies widely (tables I, II). Much of the confusion surrounding this issue can probably be related to differences in patient populations studied, study programmes and techniques used to establish ischaemia (table III). Until recently, efforts to avoid myocardial ischaemia...

Abstract Background Pre-test probability (PTP) assessment is crucial in the of patients with suspected ischaemia/coronary artery disease. Presently there no established role for artificial intelligence estimating PTP. Purpose Comparison a recently developed memetic pattern based algorithm (MPA) diagnostic power scores predicting ischaemia on positron emission tomography myocardial perfusion ima...

Changes in atrioventricular conduction coincident with myocardial anoxia were observed experimentaily in the cat over half a century ago (Lewis and Mathison, 1910), but in these experiments the prolongation of atrioventricular conduction time progressing to total atrioventricular dissociation was reversible within a few minutes of restoring full oxygenation. More recent work confirmed the actio...
