Randomized Controlled Trial
Improvement in chest compression quality using a feedback device (CPRmeter): a simulation randomized crossover study.
Cardiac arrest survival depends on celerity and efficiency of life support action. Guidelines emphasized the chest compression (CC) quality and feedback devices are encouraged. The purpose is to study the impact of the CPRmeter feedback device on resuscitation performed by untrained rescuers. ⋯ The use of the CPRmeter significantly improved CC quality performed by students inexperienced in cardiopulmonary resuscitation.

A 59-year-old woman presented to emergency department with sudden onset of chest tightness and shortness of breath. Laboratory test revealed elevated D-dimer (1558 ng/mL). The electrocardiogram revealed right axis deviation, S1Q3T3 pattern, and T-wave inversion in leads V1 to V6. ⋯ The high attenuation lesions in both of the aorta and pulmonary artery showed no contrast enhancement indicating presence of intramural hematoma (IMH). Based on the image findings, a diagnosis of type A aortic IMH with pulmonary artery extension, instead of chronic pulmonary embolism, was made. Follow-up CTA 3 months later showed much improved of the right pulmonary artery narrowing and nearly complete resolution of the IMH.

Comparative Study
Cardiac risk factors and risk scores vs cardiac computed tomography angiography: a prospective cohort study for triage of ED patients with acute chest pain.
The objective of the study is to evaluate cardiac risk factors and risk scores for prediction of coronary artery disease (CAD) and adverse outcomes in an emergency department (ED) population judged to be at low to intermediate risk for acute coronary syndrome. ⋯ Among ED patients who present with chest pain judged to be at low to intermediate risk for acute coronary syndrome, traditional risk factors are not useful to stratify risk for CAD and adverse outcomes. Coronary computed tomography angiography is an excellent predictor of CAD and outcome.
