myocardial stunning/dental caries

To assess whether myocardial lipid metabolism is altered in the "stunned" myocardium we have studied the metabolism of (1-14C)-palmitate during reperfusion in a modified rat heart preparation. Hearts were perfused retrogradely at a physiological flow rate (2 ml/min) in a non-recirculating system

BACKGROUND Transient ischaemic dilation (TID) on myocardial perfusion imaging (MPI) is an important finding, conveying a high risk of subsequent cardiac events. However, the mechanism leading to TID on MPI is not well elucidated. This study aimed to determine if TID is due to true LV cavity dilation

OBJECTIVE The effects of hypertonic saline on ventricular function are controversial, whether it is increasing contractility or preload. There are no data, however, on the influence of hypertonic saline in a stunned myocardium. METHODS This study was prospective and randomized in order to analyze

Transient stress-induced cardiomyopathies have been increasingly recognized and while rare, they tend to affect elderly women more than other demographic groups. One type, often called tako-tsubo cardiomyopathy (TTC), is typically triggered by significant emotional or physical stress and is

Takotsubo cardiomyopathy is an acute, reversible form of left ventricular dysfunction precipitated by emotional or physical stress. The condition is important to recognise as it mimics acute myocardial infarction and acute coronary syndrome. Most patients are female and postmenopausal. Presenting

OBJECTIVE Ventricular septal perforation (VSP) is a rare but life-threatening complication of acute myocardial infarction (AMI). Even with assisted circulation heart failure often progresses quickly, and urgent surgical intervention is required to close the VSP. For several years, we have been

OBJECTIVE To report a case of severe and fatal cardiac complication following pericardiotomy to relieve a malignant tamponade. Right ventricular (RV) failure was responsible for major hypoxemia and for a persistent shunt through a patent foramen ovale. In the absence of pulmonary embolism and

Pheochromocytoma is the underlying etiology in 0.1% of hypertensive cases. However, it may be present in up to 5.7% of patients with neurofibromatosis I (NF1). The burst of catecholamines inherent in pheochromocytoma has significant effects on the mechanical and electrical activity of the

The authors report the case of a post-traumatic ventricular septal defect diagnosed after the detection of a systolic murmur in a 39 year old man, 18 months after a car accident. Two-dimensional echocardiography and angioscintigraphy showed an abnormal cavity at the apex of the heart. At cardiac

Potentially fatal cardiac rupture is a complication of myocardial infarction (MI), which can appear in the first hours of the acute event and during the course of the first week. The intramyocardial dissecting hematoma might appear as a component of the rupture during the evolution process. The

Tako-Tsubo cardiomyopathy is characterised by an atypical distribution of left ventricular (LV) dysynergy with apical ballooning and compensatory basal hyperkinesis. Coronary angiography is normal. Several substrates have been put forward to explain the underlying pathophysiology such as raised
