Multicentre medicoeconomic evaluation of cardiac magnetic resonance imaging for predicting coronary artery disease in left ventricular dysfunction: The CAMAREC study design.

Background: Cardiac magnetic resonance imaging may provide a non-invasive alternative to coronary angiography for differentiating between ischaemic and non-ischaemic cardiomyopathy in cases of unexplained reduced left ventricular ejection fraction.

Aim: The CAMAREC study aims to evaluate the diagnostic accuracy of cardiac magnetic resonance imaging in predicting significant coronary artery disease in patients with reduced left ventricular ejection fraction, using coronary angiography as the gold standard for comparison.

Methods: CAMAREC is a prospective cohort study of 406 patients in 10 centres with newly diagnosed, unexplained left ventricular ejection fraction ≤ 45%.

Effectiveness of Hypnosis for the Prevention of Anxiety During Coronary Angiography (HYPCOR study): a prospective randomized study.

Background: Coronary angiography is the gold standard for the diagnosis of coronary artery disease. This intervention is nevertheless a source of anxiety for the patient both by its discomfort and by the consequences linked to the discovery of potential diseases.

Objectives: The aim of this study was to determine the effectiveness of hypnosis in reducing anxiety in patients undergoing coronary angiography.

[Renal hemosiderosis following mechanical hemolysis: An original case report].

Renal hemosiderosis is a rare cause of acute kidney injury, but it can also lead to chronic kidney failure. We report here the case of a 73-year-old patient with acute kidney caused by a massive hemosiderosis following the proximal disinsertion of a prosthesis of the ascendant aorta with chronic aortic dissection. The kidney biopsy revealed the diagnosis, showing massive iron deposits inside the proximal tubules, especially with Perls staining and also diffuse hematic casts in the lumen of the tubules.

Myocardial infarction in a 45-year-old man following an anaphylactic reaction to a wasp sting.

We present the case of a 45-year-old man with clinical features of acute coronary syndrome with persistent ST segment elevation following an anaphylactic reaction to a wasp sting treated with adrenaline. A thrombolysis is performed with no effect on clinical signs, leading to an emergency cardiac catheterization which reveals a non-occlusive thrombosis of the right coronary artery. The pathophysiology and clinical implications of this association are discussed.
