Prediction of significant coronary artery disease in acute chest pain without infarction in emergency department: MAPAC Cardio-PreTest model.

Acute nontraumatic chest pain is a frequent reaso n for consultation in emergency departments and represents a diagnostic challenge. The objective is to estimate the risk of significant coronary artery disease (CAD) in patients with cardiogenic acute chest pain for whom the diagnosis of infarction was ruled out in the emergency department with a nondiagnostic ECG and negative high-sensitivity troponins. We prospectively recruited 1625 patients from emergency departments of seven Spanish hospitals.

Imaging Assessment of Ectopic Gas Collections.

Ectopic gas is defined as the presence of gas in abnormal locations, that is, outside the aerodigestive tract. It constitutes a common radiologic finding associated with a wide range of disorders. Although it is usually an innocuous and self-limited condition, it should prompt a search for the underlying cause, given that the clinical significance of ectopic gas varies from benign to life threatening, depending on the site involved and the rate of accumulation.

Internal Carotid Artery Web as the Cause of Recurrent Cryptogenic Ischemic Stroke.

Carotid artery web is considered an exceptional cause of recurrent ischemic strokes in the affected arterial territory. The underlying pathology proposed for this entity is an atypical fibromuscular dysplasia. We present the case of a 43-year-old woman with no cardiovascular risk factors who had experienced 2 cryptogenic ischemic strokes in the same arterial territory within an 11-month period.
