BACKGROUND Two-dimensional (2D) speckle imaging has shown that it could evaluate not only regional but also global strain (epsilon) and strain rate (SR) of the left and right ventricles. There are no data for global epsilon/SR imaging for left atrial (LA) function evaluation. METHODS A total of 54 subjects (37 men; mean age, 44 +/- 10 years) with normal(More)
OBJECTIVES The objective of the present study was to investigate whether the combined use of transcricothyroid membrane ultrasonography and ultrasonographic evaluation for pleural sliding is useful for verifying endotracheal intubation in the ED. METHODS We performed a prospective clinical trial in the ED from January to July 2008. All patients enrolled(More)
Current guideline recommends that immediate coronary angiography (CAG) should be considered in all postcardiac arrest patients in whom acute coronary syndrome is suspected. In the setting of out-of-hospital cardiac arrest (OHCA), obtaining clinical data such as chest discomfort and medical diseases associated with acute coronary syndrome can be difficult.(More)
Coronary artery anomalies in patients undergoing coronary angiography are often technically challenging for invasive cardiologists and may delay revascularization time. We report a patient who underwent successful bailout revascularization using dual-source computed tomography after failed emergency angiography. This case emphasizes the utility of(More)
BACKGROUND Investigations of a strain index for the viability of ischemic myocardium with acute myocardial infarction (AMI) have been challenging. Therefore, the aim of this study was to evaluate patients with AMI to determine an optimal strain index for predicting the viability of ischemic myocardium. METHODS AND RESULTS A total of 57 patients with AMI(More)
A couple of new antistasin family serine protease inhibitors have been isolated from the non-hematophagous earthworm, Eisenia andrei. These novel inhibitors have been designated as eisenstasin I and II. Similar to other antistasin family inhibitors, eisenstasin I and II feature 3 and 4 internal repeats, respectively, of a 24–29 amino acid sequence, both of(More)
OBJECTIVE We compared training using a voice advisory manikin (VAM) with an instructor-led (IL) course in terms of acquisition of initial cardiopulmonary resuscitation (CPR) skills, as defined by the 2010 resuscitation guidelines. METHODS This study was a randomized, controlled, blinded, parallel-group trial. We recruited 82 first-year emergency medical(More)
We report a case of multicentric, biatrial cardiac myxoma in a 29-year-old female who complained of exertional dyspnea, abdominal distension and peripheral edema. Any other associated skin lesions, breast mass or endocrine disorder presenting complex form were' not seen on her. Also, there was no contributory medical history, hypertension and diabetes(More)
