An occlusion or severe stenosis (angiographic culprit lesion) of the infarct-related artery is frequently located at the site of the maximum thrombus burden, whereas the origin of the plaque rupture (the true culprit) can be situated proximal or distal to it. The aim of this study was to examine stent ...

Heart failure causes electrophysiological changes in the heart. Downregulation of repolarizing K+-currents leads to a prolongation of the cardiac action potential. Nevertheless, little is known about the differential expression of atrial and ventricular K+-channels in the failing heart. Ten rabbits underwent progressive rapid right ventricular pacing for 30 days. Digitized ECGs ...

Background: Ventricular over-drainage is a common complication of dysfunctional ventriculoperitoneal devices. Subdural haematomas are usually the most common lesions associated with that complication. Such lesions may arise after ventricular collapse and bridging veins disruption that follows over-drainage, thus contributing to distortion of brain parenchyma, increased intracranial hypertension and neurological decline. ...

It is well known that atrial infarctions are rare comparing to the ventricular. They cannot easily be verified on ECG and the standard autopsy technique does not include a detailed review of the atrial wall, so the atrial infarction often remains undiagnosed. A 63-year-old male was treated and died in ...

Sepsis-induced cardiac dysfunction is a frequent and severe complication of septic shock. The mechanisms responsible for its development are complex and intricate. Echocardiography is the best method to make the diagnosis of cardiac dysfunction. Biomarkers (B-type natriuretic peptides and cardiac troponins) can alert clinicians of the possibility of cardiac dysfunction. ...

Myocardial ischemia activates cardiac sympathetic afferents leading to chest pain and reflex cardiovascular responses. Brief myocardial ischemia leads to ATP release in the interstitial space. Furthermore, exogenous ATP and α,β-methylene ATP (α,β-meATP), a P2X receptor agonist, stimulate cutaneous group III and IV sensory nerve fibers. The present study tested the ...
