Prevalence and outcome of patients referred for chest pain with high-sensitivity troponin elevation and no diagnosis at discharge.

Introduction: Specialized chest pain units appear to increase the proportion of patients with acute chest pain who are properly evaluated, but some of them remain doubtful.

Hypothesis: The aim of this study was to evaluate the survival and occurrence of cardiovascular events in patients without diagnosis at the end of management of chest pain with high-sensitivity troponin (Tn) elevation.

Method: All consecutive patients who came to the cardiac emergency room of Poitiers University Hospital between January 1, 2014, and August 7, 2015, for chest pain and Tn elevation were included.

Pancarditis: an unusual complication of a group B streptococcal infection.

Pancarditis is a rare condition with a poor prognosis combining endocarditis, myocarditis with abscess formation, and purulent pericarditis. Diagnosis is often delayed and the clinical signs are predominantly those of the embolic complications. Literature is scarce.

Prognostic value of left atrial function in systemic light-chain amyloidosis: a cardiac magnetic resonance study.

Background: Cardiac involvement in systemic light-chain amyloidosis (AL) imparts an adverse impact on outcome. The left atrium (LA), by virtue of its anatomical location and muscular wall, is commonly affected by the amyloid process. Although LA infiltration by amyloid fibrils leads to a reduction in its pump function, the infiltration of the left ventricular (LV) myocardium results in diastolic dysfunction with subsequent increase in filling pressures and LA enlargement.

Real three-dimensional assessment of left atrial and left atrial appendage volumes by 64-slice spiral computed tomography in individuals with or without cardiovascular disease.

Context: Left atrial (LA) volume is a prognosis factor of cardiovascular morbidity in patients with cardiovascular disease (CD). Recent developments of multislice computed tomography (MSCT) have made non invasive coronary angiography reliable for selected patients and new software facilitates truly volume measurements without geometrical assumptions.

Objective: To define, by using MSCT, LA and left atrial appendage (LAA) volumes in patients with or without CD.
